Background
Following the release and success of her album Loud (2010), Rihanna originally revealed via Twitter that the album would be re-issued with new songs and released in Fall 2011, writing that "[t]he [Loud era] continues with more new music to add to [your] collection"  In September 2011, Rihanna again took to the social networking site to confirm that the plans had been scrapped, with the singer tweeting "I [thought about] a [re-release], but LOUD is its own body of work! Plus [you] guys work so hard that [you] deserve to act brand new"  On September 19, 2011, Rihanna further provoked excitement amongst her followers when she posted that she was listening to the song, only to be re-tweeted by Calvin Harris, who replied "Sometimes it feels like we find love in the most hopeless place", suggesting that his response contained possible lyrics from the song  In an interview with Capital FM, Harris – who produced the track – explained that followers of Rihanna had sent messages to him regarding their expectations of the song, saying "The song better not be rubbish", which he interpreted as slightly threatening, but went on to say that "it's all part of the fun"  In an interview for Q magazine, Harris said of the lyric, "we found love in a hopeless place," "It could have been Jumpin Jaks in Dumfries (Harris' home town), I don't know exactly what I was thinking about ""We Found Love" premiered in the United Kingdom on September 22, 2011, on Capital FM, and was sent for mainstream adds in the United States on October 11, 2011  The song was released via iTunes on September 22, 2011  During an interview with MTV News, Calvin Harris revealed, "'We Found Love,' is the most successful thing I've done ever    It's not strictly a song by me, obviously, it's by Rihanna  She sings it   It was great to work with her    No one could have taken it as far as she did  You can't escape it here [in America]  I've heard it a lot  I've heard it probably more times today than I did when I was mixing it  Which is a good thing    Ever since the Rihanna song did well, a lot of people want to do some stuff, which is great    That's what I enjoy doing  In terms of actual names, I've not done anything yet " In October 2012, British singer Leona Lewis claimed that she was originally chosen to sing the song but ended up losing it to Rihanna when Harris went touring with the latter, commenting  "I didn’t commit to it because I wanted "Trouble" to be my first single so I think that was another reason they went with Rihanna  It was the same version and production but mine’s better " In 2013, Nicole Scherzinger claimed that she was the first artist given the song but ended up rejecting it, commenting  "I've got the demo of that song and I was busy at the time  They'd sent me a few dance tracks and I wasn't able to get to them and I was like, 'Oh there's so much dance and I want to take a break from it "

Artwork
The artwork for "We Found Love" was released by Rihanna's official Facebook page on September 22, 2011  Grady Smith of Entertainment Weekly's The Music Mix criticized the song's artwork, writing "'We found love in a hopeless place,' Rihanna repeats over a David Guetta-ish synth beat  But judging by the single cover, her place doesn't look too hopeless, does it? Maybe there's a building on fire outside the frame, and that fire hydrant doesn't work  I guess that would be hopeless " A reviewer for Sugar Magazine wrote that "On anyone else this would be a pretty odd look but Rihanna somehow makes a denim overload look good " A reviewer for Neon Limelight commented that Rihanna appeared to be adopting a tomboy image for the new project, writing, "She really is going for that sexy tomboy look this album era it seems; remember the laid back look she rocked on the single's cover art?" 

Composition
"We Found Love" is an electro house song with elements of Europop, pop, techno, dance-pop, trance, and Euro disco  According to the digital music sheet published at musicnotes com, the song is written in the key of F ♯ major and it is set at a tempo of 128 beats per minute  The instrumentation of "We Found Love" consists of alarm bells, a keyboard, repetitive pumped-up synthesizers and 4/4 beats Rihanna's vocal range in the song spans one octave, from the lower note of C♯4 to the higher note of C♯5  Priya Elan of NME commented that Rihanna sounds "extremely relaxed" and Bill Lamb of About com wrote that her vocals are simple and unaffected  Leah Collins of The Vancouver Sun wrote that Rihanna's vocals on "We Found Love" were similar to her vocals on "Fly"  According to Elan, the keyboard work in the song bears resemblance to that in from "Only Girl (In the World)" and the melody is similar to that of "Complicated", a track included in Rihanna's 2010 studio album Loud  Similarly, Michael Cragg of The Guardian noted that "We Found Love" is in the same vein as "Only Girl (In the World)", with regard to its dance beat The lyrical content of the song is sparse and largely revolves around Rihanna chanting the song's hook line, "We found love in a hopeless place"  Jody Rosen of Rolling Stone described it as "half-baked romantic"   Rihanna starts the song in a falsetto airy voice as she sings, "Yellow diamonds in the light / And we’re standing side by side / As your shadow crosses mine / What it takes to come alive " Michael Cragg commented that the first chorus is almost being sidelined in favor of a large chunk of Harris's riff, before they join on the second chorus  The hook repeatedly rings throughout the song 

Critical reception
The song received polarized reviews from music critics  Amanda Dobbins of New York magazine praised the composition of the song, writing "Harris's electro fingerprints are all over this one — it plays like a straight house track, with some dreamy Rihanna vocals added in over the beat " Robbie Daw of Idolator commented on the song's lyrics, with particular emphasis on the line "We found love in a hopeless place", writing that it is possibly the best lyric in pop music so far in 2011  A reviewer for Instinct magazine praised the song, writing that "We Found Love" does not mark a departure from the dance-floor oriented material Rihanna debuted on Loud, but it certainly boasts "a higher-energy, peak-hour vibe"  Similarly, Michael Cragg of The Guardian commented that the song takes the dance direction Rihanna hinted at on "Only Girl (In the World)" and continues releasing similar songs, making reference to "We Found Love"  Cragg also likened the song to Leona Lewis's recent single, "Collide", but criticized the song's structure, writing "[it] is slightly odd"  He ended his review writing, "Either way, she could have recited Nick Clegg's conference speech from Wednesday over the sound of Harris cracking his knuckles and it would be a hit "Priya Elan of NME commented, "By now it's pretty customary to have a jaw-on-the-floor reaction to the first single from a Rihanna album  'Pon De Replay', 'SOS', 'Umbrella', 'Russian Roulette', 'Only Girl In The World' " Despite complimenting Rihanna for sounding extremely relaxed and calling her vocal as "luxurious calling to mind the atmosphere", Elan concluded that the over-all effect is underwhelming  She continued by writing that instead of re-inventing the pop wheel, "We Found Love" has "a whiff of treading-water about it" and that "if there is a 'goosebump' moment to be had it comes after many multiple plays and, dare we say it, a glass of something strong " Awarding "We Found Love" two stars out of five, Jody Rosen of Rolling Stone was critical, writing that it "is much ado about very little indeed" and that is "an insipid tune"  He concluded that Rihanna repeats 'We found love in a hopeless place' "approximately 350 times, hoping it will start to mean something  It's the worst single of Rihanna’s career  It will probably top the Hot 100 anyway " Leah Collins of The Vancouver Sun initially praised Rihanna's vocal performance in the song, writing that she "smoothes out her vocals", before adding, "Angelic as she sounds, though, [her] performance – which is mostly just her repeating the line 'We found love in a hopeless place' – seems to take second place to Harris' repetitive synth-based blare " Similarly, Amos Barshad of Grantland criticized the singer's vocal performance, calling it "a complete afterthought" before concluding, "People who regularly attend the Electric Zoo festival: Rihanna wants your money!"A reviewer for GlobalGrind commented on the song's lyrics, suggesting that there is perhaps an underlying message in the song for ex-boyfriend Chris Brown, in the line "We found love in a hopeless place"  This further raised suspicion when Brown re-tweeted one of Rihanna's posts on Twitter, which read "Sometimes it feels like we find love in the most hopeless place"  Jessica Herndon of People magazine praised the song, saying that "'We Found Love' had an amazing influence on people all across the world in 2012, becoming one of the most popular and most successful songs" Pitchfork Media commented, "Over a frantic, Calvin Harris-produced, Guetta-meets-'Sandstorm' beat on her sixth record's lead-off single, Rihanna repeats these words almost 20 times  'We Found Love' ranks among Ri's best singles because it recognizes that there's not much more that needs to be said: in three and a half minutes, the line moves from being a great pop lyric to a triumphant mantra to something suggestive of a whole spectrum of unspoken emotion  The best pop music transports you to somewhere beyond words, and Rihanna's strongest singles all seem to be in on this secret " Allmusic chose the song as a highlight on Talk That Talk, and wrote about the "singer's ecstatic vocal than Calvin Harris' shrill, plinky production"  Los Angeles Times commented that the song was an "ode for bad love" and added it "wouldn't be out of place at Electric Daisy Carnival"  The New York Times' writer commented "'We Found Love' almost criminally recalls the swinging Crystal Waters singles, with triumphant percussion somewhere between church and seventh-inning stretch " Billboard magazine also praised the song, saying that: "Through a haze of glitter and bliss, Rihanna emerges to let us find a gorgeous hook in a hopeless place, and Calvin Harris becomes a household name " As of January 2015, Billboard named "We Found Love" as the best song of the 2010s (so far)  USA Today considered the song to be a highlight on the set, commenting that Rihanna sings "bistfully"   Entertainment Weekly noted, "U K  club king Calvin Harris trades Rihanna's usual somber synths for disco ecstasy on 'We Found Love,' a song that builds and builds to a climax that's so arena-ready it practically begs for someone to blow a vuvuzela" 

Recognition and awards
MTV chose "We Found Love" as the third best song of 2011, and "Video of the Year" at the MTV Video Music Awards 2012  The writers of the website further commented, "The leadoff single from Talk That Talk is where Rihanna fully embraced EDM  Produced by Calvin Harris, 'We Found Love' is a swirling party track about love and loss, the rare song that manages to be sad and joyous all at once  And it is a pinnacle of the pop/dance crossover, a throwback to '90s raves that could make even the most stoic lover of pop want to break out a glow stick and just dance  Rob Sheffield of Rolling Stone put "We Found Love" at number eleven on his list of Top 25 Songs of 2011 commenting, "While her other hits tried to camouflage her spindly voice, here it just strains for that spindly melody " It was named the third biggest love song of all time by Billboard

Music video
The music video for "We Found Love" was shot in Northern Ireland in late September 2011, in County Down, Northern Ireland and the New Lodge area of North Belfast   The video was directed by Melina Matsoukas, who had previously directed the videos for "Hard" (2009), "Rude Boy" (2010), "Rockstar 101" (2010) and the controversial "S&M" (2011)  Anticipation for the video grew in the United Kingdom when the national news picked up on the story of sixty-one-year-old Northern Ireland farmer Alan Graham withdrawing his permission to film in his barley field in Bangor, County Down after taking issue with Rihanna's clothing, focusing on her appearing topless and also wearing a red bikini top which he thought was an "inappropriate state of undress"  Rihanna and her film crew departed amiably after Graham advised them to "be acquainted with God and to consider His Son, the Lord Jesus Christ, and His death and Resurrection "The video begins with a monologue about love and heartbreak by an unseen narrator, fashion model Agyness Deyn  Multiple scenes of Rihanna and boxer Dudley O'Shaughnessy are intercut throughout the narration, depicting them in different love and hate situations with each other  The two are shown as completely enamored with each other while engaging in fun activities together, including enjoying their time at an indoor skating centre and eating in fast food restaurants  During the chorus, the video shows the romance to be somewhat warped, as images of drugs, various pills and dilated pupils are shown, while brief scenes of Rihanna and her boyfriend preparing to engage in sexual intercourse and their various stages of undress are shown  The chorus continues and the video abruptly cuts to Rihanna and other people at an outdoor rave, dancing to music  Calvin Harris features as the DJ during this scene 
From the second verse, Rihanna and her boyfriend are seen happily running amok in a supermarket, pushing each other in a shopping cart and spraying canned drinks at each other  This scene is interrupted with Rihanna in a Pontiac Trans Am outside with her boyfriend who begins to recklessly drive in circles, resulting in Rihanna asking him to stop the car which ensues into an argument between the pair  The video then progressively shows the couple experiencing mounting difficulties in their relationship  Rihanna removes herself from the car and returns moments later where we see her boyfriend grab her chin to look at him, suggesting that he is domestically violent towards her  During the final chorus Rihanna can be seen vomiting what appears to be pink and white streamers; she is also seen passed out on the street while her boyfriend tries to revive her  In another scene, Rihanna is seen lying on a couch while her boyfriend tattoos the word 'MINE' on her backside  Eventually, Rihanna decides to leave her boyfriend after finding him passed out on the floor of his apartment – and most likely due to the previous events shown throughout the video  The clip ends with Rihanna curled up in the corner of a room, crying The video generated controversy for its depiction of violence and drug use, as well as for Rihanna's removal of her clothes during filming  One journalist wrote, "The song is probably one of the most talked about in the country following the Barbadian being told to 'find God' after running naked through a Northern Irish farmer's field " It was described as a "disgrace" by an anti-rape campaigner, and Christian commenters worried about the effects of the video and that "Rihanna is damaging the moral and self-worth of young impressionable teens " However, The Guardian praised the video for being different in its time period and called it "a very British music video", comparing it to UK TV series, Skins  The video won a Grammy Award for 'Best Short-Form Music Video  As of January 2015, Billboard named the video as the second best music video of the 2010s (so far)

YouTubers Tom Scott and Matt Gray spoofed the song in their video 'Ten Illegal Things To Do In London ' The parody, where the song's chorus lyrics are replaced with 'We Flew A Kite In A Public Place,' plays over footage of Gray flying a kite in a public place, which is illegal in the U K  under the Metropolitan Police Act 1839 

Remixes
In November 2011, R3hab released a remix of "We Found Love" with a "Halloween" sound  He explained "I made two versions     one version is more melodic and euphoric  This [first] one is more dark because the lyrics [to] 'We Found Love' can also be seen as something dark  'We are at the end of the world/ And I still found love ' So from there came the more darker chord progression and the more darker atmosphere, like Dracula is coming to get you  It's just got a lot of emotion and that worked out great for me "On January 13, 2012, Rap-Up released a remix of "We Found Love" featuring American rapper Flo Rida  Flo Rida's parts overlap Calvin Harris' produced dance beats  In the opening lines, Flo Rida introduces himself and raps tongue twisters about Rihanna and The Bahamas, "You know I got love for you/ See what happened was we in Bahams/ I remember it was the ox summer, oh so pretty I/   Girl nice to meet you what's the honour/ Yeah she tap me told me she Rihanna "  He also references singer Mick Jagger singing that he is "rocking a party 'like I'm Mick Jagger " Flo Rida, himself in an interview with NME revealed that it was an honor for him to work with Rihanna  He also revealed that "We Found Love" was one of his favorite songs and that's why he decided to make a remix with Rihanna  He added that Calvin Harris' production impressed him and heavily influenced him on his future work  Rihanna also noted that she decided to work with Flo Rida because of his "wild" productions on his songs Andrew Unterberger of the website PopDust wrote that Flo Rida was "exactly" what the original version of "We Found Love" was missing  He added, "No Rihanna, you got it backwards—it's Flo Rida who needs to have other, more talented people on his songs in order to turn them into hits, not the other way around    At least this remix does feature a sizeable contribution from Flo, as he shows up on both the intro and over the song's primary instrumental hook with his trademark unintelligible yammering, though he gets in at least one reference to rocking a party 'like I'm Mick Jagger '" Matthew Perpetua of Rolling Stone praised the remix of the song, saying that "once again, Flo Rida shows his true rapping skills over the beat of Rihanna's 'We Found Love'"  Both Billboard's Erika Ramirez and Spin's Marc Hogan praised the remixed version calling it "refreshing" and "interesting"  However, Becky Bain of the website Idolator was more negative towards the remix  She noted, "Being that Rihanna's 'We Found Love' has enough beats and synths to be its own remix, not to mention it couldn't possibly be even more popular on the Hot 100    we find it pointless to release a new version of the single with Flo Rida "

Sometimes the brightest gems are right in front of your eyes, hiding in plain sight  Or just obscured by people who know they are there, but have forgotten to tell you 
With this song, and its fantastic video, I will admit that my attention was miles away, probably raking through some slower, drabber, less fun things (ie: ANYTHING ELSE)  I had no idea something this ker-ay-zee, this life-affirming, this astonishingly chipper was released across on my beloved internet just seven days ago, until a friend dragged me over to look at what he called "the skipping video" on his phone 
Yeah, that's right, a skipping video  I mean how impressive can a video which features people either successfully or unsuccessfully jumping over a moving rope actually b   oh my LORD have you SEEN THE SKIPPING VIDEO? YOU'VE GOT TO SEE THE SKIPPING VIDEO! THE SKIPPING VIDEO IS AMAZING!

Grace Kelly (song)
"Grace Kelly" is the second single by British singer Mika  It is the opening track on Mika's debut studio album Life in Cartoon Motion (2007)  Produced and mixed by Greg Wells, the song entered the UK Singles Chart at number three and the UK Official Download Chart at number one  One week later, it jumped to the top of the UK Singles Chart on download sales alone, the second song to do so after Gnarls Barkley's "Crazy" the previous year  The track was number one on the UK Singles Chart for five weeks, and ended 2007 as the year's third biggest-selling single in that country  In the US, "Grace Kelly" was made available for digital download on 16 January 2007  This song was also No  89 on MTV Asia's list of Top 100 Hits of 2007  It was designed to be a mocking satire of musicians who try to reinvent themselves to be popular 
The song is titled after Academy Award-winning American film and stage actress, and Princess of Monaco, Grace Kelly  The bit of dialogue used in the song is from the film The Country Girl, which stars Kelly  Mika claims the song was inspired after a bad experience with a record company executive, in which he was told to be more like Craig David  The lyric "So I tried a little Freddie" is a reference to Queen's Freddie Mercury, to whose singing voice Mika's has been compared  On at least one occasion, Mika confirmed that he used the main melody from Figaro's famous aria "Largo al factotum", from the opera The Barber of Seville by Gioachino Rossini  Mika performed the song at the MTV Europe Music Awards 2007 in Munich and at the 2008 BRIT Awards at the Earls Court Exhibition Centre, London, where it was nominated for Best British Single, but lost to "Shine" by Take That  The song has sold over 630,000 copies in the UK, as stated by the Official Charts Company 

Background and composition
Mika wrote the song after he felt frustrated with record label executives that wanted him to change his sound to fit the common pop mold  In the song, Mika points out how he can pretend to be anyone he likes to win approval – in this case the glamorous actress Grace Kelly  He wrote the song after the record company told him that they wanted to model his look and sound on Craig David, who was popular at the time in the UK  Mika rejected this idea and wrote "Grace Kelly" as a way of expressing his individuality  The song's melody is based on the aria "Largo al factotum", from the opera The Barber of Seville by Gioachino Rossini 

Critical reception
The song received positive reviews from music critics  Heather Phares from AllMusic wrote a positive review for the song, stating that "Mika's singles are his most charming moments, including the instant sunshine of "Grace Kelly," which crams tap-dancing rhythms, filmic dialogue, Elton's pianos, Freddie's vocal harmonies, and Brian May's guitars into just over three minutes " Christian John Wikane from PopMatters wrote an extensive article about the comparisons between Mika and Freddie Mercury, writing that "he sounds a lot like Mercury and wears the influence like a badge of honor, even name-checking the late front man of Queen in the first verse  Mika vacillates between the affected theatricality of Mercury's full-throttled voice and his own strong falsetto, where he earnestly implores "Why don't you like me?" no less than 12 times Beth Johnson from Entertainment Weekly wrote that "Nothing quite matches the crystal-shattering exuberance of hit Grace Kelly " John Murphy from musicOMH wrote that "It's big, joyous, dumb pop, and the only danger with it is that you'll be utterly sick of it fast " Lizzie Enever from BBC Music was direct, writing that "Grace Kelly is a great pop song – it's catchy, you can't help singing along and it grates on you after a few days when you can't get it out of your head but you still go back for more – flawless credentials " Graham Griffith, also from About com, wrote that the song "is an outrageously irresistible and infectious pop gem " Dom Passantino from Stylus Magazine criticized the track, writing that "it seems to suggest the boy has some level for musicals, being as it is all Broadway flittering and hackneyed attempts at conveying a story with its lyrics  But here's the problem: he's got no tales to tell, just a tab at his local make-up supplier  "Am I too dirty, am I too flirty?" he sings at one point "

Accolades
At the 2007 World Music Awards, Mika won for Best Selling British Artist, Best Selling New Artist, Best Selling Male Entertainer, and World's Best Selling Pop Rock Male Artist

Biography
Bennett was born in Twin Falls, Idaho  He joined the NASA headquarters in June 1988 as the Manager of Advanced Space Power Systems in the transportation division of the Office of Advanced Concepts and Technology  There, he managed a number of transportation technology programs including hybrid propulsion, electric propulsion, low-thrust chemical propulsion, and other advanced propulsion concepts (e g , fusion, antimatter)  He was also the first program manager of the advanced technology insertion program for the Pluto Fast Flyby (now New Horizons) mission and the TIMED space physics mission 
Prior to coming to NASA, Bennett held key positions in DoE's space radioisotope power program, including serving as Director of Safety and Nuclear Operations for the radioisotope power sources that were used on the Galileo mission to Jupiter and that are being used on the Ulysses mission to explore the polar regions of the Sun   This same radioisotope power source design was then flown on the Cassini mission to Saturn and on the New Horizons mission to Jupiter 
Previous positions included Chief of the Research Support Branch in the US Nuclear Regulatory Commission (NRC) where Bennett was instrumental in creating and managing NRC's reactor operational safety research program 
Bennett was the flight safety manager for the radioisotope power sources currently in use on the Voyager 1 and Voyager 2 spacecraft (which went to Jupiter, Saturn, Uranus, Neptune and beyond) and on Lincoln Laboratory's LES 8 and LES 9 communications satellites 
Bennett also worked as a physicist in the NERVA (Nuclear Engine for Rocket Vehicle Applications) program at what was then NASA's Lewis Research Center (now the John H  Glenn Research Center) in Cleveland, Ohio   He did fundamental reactor safety research at what is now the Department of Energy's Idaho National Laboratory (INL) 
From 1980 to 1988, he was a member of or adviser to US delegations to the two subcommittees of the United Nations Committee on the Peaceful Uses of Outer Space and he prepared the official US position papers on the use of nuclear power sources in outer space 
From 1988 to 1990, Bennett chaired the Steering Group of the Interagency Advanced Power Group (IAPG), the national coordinating group for federally sponsored space and terrestrial power research   During his tenure and under his initiative the IAPG saw its greatest increase in membership 
Bennett received his PhD in physics from Washington State University in 1970; a Master of Nuclear Science degree in 1966, and a BSc degree in physics from the University of Idaho in 1962; and an Associate of Arts degree from Boise Junior College (now Boise State University) in 1960 
Since 1995, he has been active in promoting the teaching of science (specifically evolution) and received the Friend of Darwin Award  Bennett has also been a champion of the First Amendment and was elected to the National Advisory Council of Americans United for Separation of Church and State

Passage 2:
Planetary protection
Planetary protection is a guiding principle in the design of an interplanetary mission, aiming to prevent biological contamination of both the target celestial body and the Earth in the case of sample-return missions  Planetary protection reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail There are two types of interplanetary contamination  Forward contamination is the transfer of viable organisms from Earth to another celestial body   Back contamination is the transfer of extraterrestrial organisms, if they exist, back to the Earth's biosphere 

History
The potential problem of lunar and planetary contamination was first raised at the International Astronautical Federation VIIth Congress in Rome in 1956 In 1958 the U S  National Academy of Sciences (NAS) passed a resolution stating, “The National Academy of Sciences of the United States of America urges that scientists plan lunar and planetary studies with great care and deep concern so that initial operations do not compromise and make impossible forever after critical scientific experiments ” This led to creation of the ad hoc Committee on Contamination by Extraterrestrial Exploration (CETEX), which met for a year and recommended that interplanetary spacecraft be sterilized, and stated, “The need for sterilization is only temporary  Mars and possibly Venus need to remain uncontaminated only until study by manned ships becomes possible” In 1959, planetary protection was transferred to the newly formed Committee on Space Research (COSPAR)  COSPAR in 1964 issued Resolution 26 affirming that:

the search for extraterrestrial life is an important objective of space research, that the planet of Mars may offer the only feasible opportunity to conduct this search during the foreseeable future, that contamination of this planet would make such a search far more difficult and possibly even prevent for all time an unequivocal result, that all practical steps should be taken to ensure that Mars be not biologically contaminated until such time as this search has been satisfactorily carried out, and that cooperation in proper scheduling of experiments and use of adequate spacecraft sterilization techniques is required on the part of all deep space probe launching authorities to avoid such contamination 
In 1967, the US, USSR, and UK ratified the United Nations Outer Space Treaty   The legal basis for planetary protection lies in Article IX of this treaty:
"Article IX:     States Parties to the Treaty shall pursue studies of outer space, including the Moon and other celestial bodies, and conduct exploration of them so as to avoid their harmful contamination and also adverse changes in the environment of the Earth resulting from the introduction of extraterrestrial matter and, where necessary, shall adopt appropriate measures for this purpose    
This treaty has since been signed and ratified by 104 nation-states  Another 24 have signed but not ratified   All the current space-faring nation-states, along with all current aspiring space-faring nation-states, have both signed and ratified the treaty The Outer Space Treaty has consistent and widespread international support, and as a result of this, together with the fact that it is based on the 1963 declaration which was adopted by consensus in the UN National Assembly, it has taken on the status of customary international law  The provisions of the Outer Space Treaty are therefore binding on all states, even those who have neither signed nor ratified it For forward contamination, the phrase to be interpreted is "harmful contamination"   Two legal reviews came to differing interpretations of this clause (both reviews were unofficial)  However the currently accepted interpretation is that “any contamination which would result in harm to a state’s experiments or programs is to be avoided”  NASA policy states explicitly that “the conduct of scientific investigations of possible extraterrestrial life forms, precursors, and remnants must not be jeopardized” 

COSPAR recommendations and categories
The Committee on Space Research (COSPAR) meets every two years, in a gathering of 2000 to 3000 scientists, and one of its tasks is to develop recommendations for avoiding interplanetary contamination  Its legal basis is Article IX of the Outer Space Treaty  (see history below for details) 
Its recommendations depend on the type of space mission and the celestial body explored   COSPAR categorizes the missions into 5 groups:

Category I: Any mission to locations not of direct interest for chemical evolution or the origin of life, such as the  Sun or Mercury  No planetary protection requirements 
Category II: Any mission to locations of significant interest for chemical evolution and the origin of life, but only a remote chance that spacecraft-borne contamination could compromise investigations  Examples include the Moon, Venus, and comets  Requires simple documentation only, primarily to outline intended or potential impact targets, and an end of mission report of any inadvertent impact site if such occurred 
Category III: Flyby and orbiter missions to locations of significant interest for chemical evolution or the origin of life, and with a significant chance that contamination could compromise investigations e g , Mars, Europa, Enceladus  Requires more involved documentation than Category II  Other requirements, depending on the mission, may include trajectory biasing, clean room assembly, bioburden reduction, and if impact is a possibility, inventory of organics 
Category IV: Lander or probe missions to the same locations as Category III  Measures to be applied depend on the target body and the planned operations  "Sterilization of the entire spacecraft may be required for landers and rovers with life-detection experiments, and for those landing in or moving to a region where terrestrial microorganisms may survive and grow, or where indigenous life may be present  For other landers and rovers, the requirements would be for decontamination and partial sterilization of the landed hardware "Missions to Mars in category IV are subclassified further:Category IVa  Landers that do not search for Martian life - uses the Viking lander pre-sterilization requirements, a maximum of 300,000 spores per spacecraft and 300 spores per square meter 
Category IVb  Landers that search for Martian life   Adds stringent extra requirements to prevent contamination of samples 
Category IVc  Any component that accesses a Martian special region (see below) must be sterilized to at least to the Viking post-sterilization biological burden levels of 30 spores total per spacecraft Category V: This is further divided into unrestricted and restricted sample return Unrestricted Category V: samples from locations judged by scientific opinion to have no indigenous lifeforms  No special requirements 
Restricted Category V: (where scientific opinion is unsure) the requirements include: absolute prohibition of destructive impact upon return, containment of all returned hardware which directly contacted the target body, and containment of any unsterilized sample returned to Earth For Category IV missions, a certain level of biological burden is allowed for the mission  In general this is expressed as a 'probability of contamination', required to be less than one chance in 10,000 of forward contamination per mission, but in the case of Mars Category IV missions (above) the requirement has been translated into a count of Bacillus spores per surface area, as an easy to use assay method More extensive documentation is also required for Category IV  Other procedures required, depending on the mission, may include trajectory biasing, the use of clean rooms during spacecraft assembly and testing, bioload reduction, partial sterilization of the hardware having direct contact with the target body, a bioshield for that hardware, and, in rare cases, complete sterilization of the entire spacecraft For restricted Category V missions, the current recommendation is that no uncontained samples should be returned unless sterilized  Since sterilization of the returned samples would destroy much of their science value, current proposals involve containment and quarantine procedures  For details, see Containment and quarantine below  Category V missions also have to fulfill the requirements of Category IV to protect the target body from forward contamination 

Mars special regions
A special region is a region classified by COSPAR where terrestrial organisms could readily propagate, or thought to have a high potential for existence of Martian life forms  This is understood to apply to any region on Mars where liquid water occurs, or can occasionally occur, based on the current understanding of requirements for life 
If a hard landing risks biological contamination of a special region, then the whole lander system must be sterilized to COSPAR category IVc 

Target categories
Some targets are easily categorized  Others are assigned provisional categories by COSPAR, pending future discoveries and research 
The 2009 COSPAR Workshop on Planetary Protection for Outer Planet Satellites and Small Solar System Bodies covered this in some detail  Most of these assessments are from that report, with some future refinements  This workshop also gave more precise definitions for some of the categories:

Category I
“not of direct interest for understanding the process of chemical evolution or the origin of life ” 
Io, Sun, Mercury, undifferentiated metamorphosed asteroids

Category II
… where there is only a remote chance that contamination carried by a spacecraft could jeopardize future exploration”  In this case we define “remote chance” as “the absence of niches (places where terrestrial microorganisms could proliferate) and/or a very low likelihood of transfer to those places ” 
Callisto, comets, asteroids of category P, D, and C, Venus, Kuiper belt objects (KBO) < 1/2 size of Pluto 

Provisional Category II
Ganymede, Titan, Triton, the Pluto–Charon system, and other large KBOs (> 1/2 size of Pluto), CeresProvisionally, they assigned these objects to Category II  However, they state that more research is needed, because there is a remote possibility that the tidal interactions of Pluto and Charon could maintain some water reservoir below the surface  Similar considerations apply to the other larger KBOs 
Triton is insufficiently well understood at present to say it is definitely devoid of liquid water  The only close up observations to date are those of Voyager 2 
In a detailed discussion of Titan, scientists concluded that there was no danger of contamination of its surface, except short term adding of negligible amounts of organics, but Titan could have a below surface water reservoir that communicates with the surface, and if so, this could be contaminated 
In the case of Ganymede, the question is, given that its surface shows pervasive signs of resurfacing, is there any communication with its subsurface ocean? They found no known mechanism by which this could happen, and the Galileo spacecraft found no evidence of cryovolcanism  Initially, they assigned it as Priority B minus, meaning that precursor missions are needed to assess its category before any surface missions  However, after further discussion they provisionally assigned it to Category II, so no precursor missions are required, depending on future research 
If there is cryovolcanism on Ganymede or Titan, the undersurface reservoir is thought to be 50 – 150 km below the surface  They were unable to find a process that could transfer the surface melted water back down through 50 km of ice to the under surface sea  This is why both Ganymede and Titan were assigned a reasonably firm provisional Category II, but pending results of future research 
Icy bodies that show signs of recent resurfacing need further discussion and might need to be assigned to a new category depending on future research  This approach has been applied, for instance, to missions to Ceres  The planetary protection Category is subject for review during the mission of the Ceres orbiter (Dawn) depending on the results found 

Category III / IV
“…where there is a significant chance that contamination carried by a spacecraft could jeopardize future exploration ” We define “significant chance” as “the presence of niches (places where terrestrial microorganisms could proliferate) and the likelihood of transfer to those places ” 
Mars because of possible subsurface habitats 
Europa because of its subsurface ocean 
Enceladus because of evidence of water plumes 

Category V
Unrestricted Category V: “Earth-return missions from bodies deemed by scientific opinion to have no indigenous life forms ”
Restricted Category V: "Earth-return missions from bodies deemed by scientific opinion to be of significant interest to the process of chemical evolution or the origin of life "
In the category V for sample return the conclusions so far are:
Unrestricted Category V: Venus, the Moon 
Restricted Category V: Mars, Europa, Enceladus 

The Coleman–Sagan equation
The aim of the current regulations is to keep the number of microorganisms low enough so that the probability of contamination of Mars (and other targets) is acceptable  It is not an objective to make the probability of contamination zero 
The aim is to keep the probability of contamination of 1 chance in 10,000 of contamination per mission flown  This figure is obtained typically by multiplying together the number of microorganisms on the spacecraft, the probability of growth on the target body, and a series of bioload reduction factors 
In detail the method used is the Coleman–Sagan equation

   is a number chosen by Sagan et al , somewhat arbitrarily  Sagan and Coleman assumed that about 60 missions to the Mars surface would occur before the exobiology of Mars is thoroughly understood, 54 of those successful, and 30 flybys or orbiters, and the number was chosen to endure a probability to keep the planet free from contamination of at least 99 9% over the duration of the exploration period 

Critiques
The Coleman–Sagan equation has been criticised because the individual parameters are often not known to better than a magnitude or so  For example, the thickness of the surface ice of Europa is unknown, and may be thin in places, which can give rise to a high level of uncertainty in the equation  It has also been criticised because of the inherent assumption made of an end to the protection period and future human exploration  In the case of Europa, this would only protect it with reasonable probability for the duration of the period of exploration Greenberg has suggested an alternative, to use the natural contamination standard — that our missions to Europa should not have a higher chance of contaminating it than the chance of contamination by meteorites from Earth 
As long as the probability of people infecting other planets with terrestrial microbes is substantially smaller than the probability that such contamination happens naturally, exploration activities would, in our view, be doing no harm  We call this concept the natural contamination standard 
Another approach for Europa is the use of binary decision trees which is favoured by the Committee on Planetary Protection Standards for Icy Bodies in the Outer Solar System under the auspices of the Space Studies Board  This goes through a series of seven steps, leading to a final decision on whether to go ahead with the mission or not 
Recommendation: Approaches to achieving planetary protection should not rely on the multiplication of bioload estimates and probabilities to calculate the likelihood of contaminating Solar System bodies with terrestrial organisms unless scientific data unequivocally define the values, statistical variation, and mutual independence of every factor used in the equation Recommendation: Approaches to achieving planetary protection for missions to icy Solar System bodies should employ a series of binary decisions that consider one factor at a time to determine the appropriate level of planetary protection procedures to use 

Containment and quarantine for restricted Category V sample return
In the case of restricted Category V missions, Earth would be protected through quarantine of sample and astronauts in a yet to be built Biosafety level 4 facility  In the case of a Mars sample return, missions would be designed so that no part of the capsule that encounters the Mars surface is exposed to the Earth environment  One way to do that is to enclose the sample container within a larger outer container from Earth, in the vacuum of space  The integrity of any seals is essential and the system must also be monitored to check for the possibility of micro-meteorite damage during return to Earth The recommendation of the ESF report is that
“No uncontained Mars materials, including space craft surfaces that have been exposed to the Mars environment should be returned to Earth unless sterilised"   "For unsterilised samples returned to Earth, a programme of life detection and biohazard testing, or a proven sterilisation process, shall be undertaken as an absolute precondition for the controlled distribution of any portion of the sample ”
No restricted category V returns have been carried out  During the Apollo program, the sample-returns were regulated through the Extra-Terrestrial Exposure Law  This was rescinded in 1991, so new regulations would need to be enacted  The Apollo era quarantine procedures are of interest as the only attempt to date of a return to Earth of a sample that, at the time, was thought to have a remote possibility of including extraterrestrial life 
Samples and astronauts were quarantined in the Lunar Receiving Laboratory  The methods used would be considered inadequate for containment by modern standards  Also the lunar receiving laboratory would be judged a failure by its own design criteria as the sample return didn't contain the lunar material, with two failure points during the Apollo 11 return mission, at the splashdown and at the facility itself 
However the Lunar Receiving Laboratory was built quickly with only two years from start to finish, a time period now considered inadequate  Lessons learned from it can help with design of any Mars sample return receiving facility Design criteria for a proposed Mars Sample Return Facility, and for the return mission, have been developed by the American National Research Council, and the European Space Foundation  They concluded that it could be based on biohazard 4 containment but with more stringent requirements to contain unknown microorganisms possibly as small as or smaller than the smallest Earth microorganisms known, the ultramicrobacteria  The ESF study also recommended that it should be designed to contain the smaller gene transfer agents if possible, as these could potentially transfer DNA from martian microorganisms to terrestrial microorganisms if they have a shared evolutionary ancestry  It also needs to double as a clean room facility to protect the samples from terrestrial contamination that could confuse the sensitive life detection tests that would be used on the samples 
Before a sample return, new quarantine laws would be required  Environmental assessment would also be required, and various other domestic and international laws not present during the Apollo era would need to be negotiated 

Decontamination procedures
For all spacecraft missions requiring decontamination, the starting point is clean room assembly in US federal standard class 100 cleanrooms  These are rooms with fewer than 100 particles of size 0 5 µm or larger per cubic foot  Engineers wear cleanroom suits with only their eyes exposed  Components are sterilized individually before assembly, as far as possible, and they clean surfaces frequently with alcohol wipes during assembly  Spores of Bacillus subtilis was chosen for not only its ability to readily generate spores, but its well-established use as a model species  It is a useful tracker of UV irradiation effects because of its high resilience to a variety of extreme conditions  As such it is an important indicator species for forward contamination in the context of planetary protection 
For Category IVa missions (Mars landers that do not search for Martian life), the aim is to reduce the bioburden to 300,000 bacterial spores on any surface from which the spores could get into the Martian environment  Any heat tolerant components are heat sterilized to 114 °C  Sensitive electronics such as the core box of the rover including the computer, are sealed and vented through high-efficiency filters to keep any microbes inside For more sensitive missions such as Category IVc (to Mars special regions), a far higher level of sterilization is required  These need to be similar to levels implemented on the Viking landers, which were sterilized for a surface which, at the time, was thought to be potentially hospitable to life similar to special regions on Mars today 
In microbiology, it is usually impossible to prove that there are no microorganisms left viable, since many microorganisms are either not yet studied, or not cultivable  Instead, sterilization is done using a series of tenfold reductions of the numbers of microorganisms present  After a sufficient number of tenfold reductions, the chance that there any microorganisms left will be extremely low The two Viking Mars landers were sterilized using dry heat sterilization   After preliminary cleaning to reduce the bioburden to levels similar to present day Category IVa spacecraft, the Viking spacecraft were heat-treated for 30 hours at 112 °C, nominal 125 °C (five hours at 112 °C was considered enough to reduce the population tenfold even for enclosed parts of the spacecraft, so this was enough for a million-fold reduction of the originally low population) Modern materials however are often not designed to handle such temperatures, especially since modern spacecraft often use "commercial off the shelf" components  Problems encountered include nanoscale features only a few atoms thick, plastic packaging, and conductive epoxy attachment methods  Also many instrument sensors cannot be exposed to high temperature, and high temperature can interfere with critical alignments of instruments As a result, new methods are needed to sterilize a modern spacecraft to the higher categories such as Category IVc for Mars, similar to Viking  Methods under evaluation, or already approved, include:

Vapour phase hydrogen peroxide - effective, but can affect finishes, lubricants and materials that use aromatic rings and sulfur bonds  This has been established, reviewed, and a NASA/ESA specification for use of VHP has been approved by the Planetary Protection Officer, but it has not yet been formally published 
Ethylene oxide - this is widely used in the medical industry, and can be used for materials not compatible with hydrogen peroxide  It is under consideration for missions such as ExoMars 
Gamma radiation and electron beams have been suggested as a method of sterilization, as they are used extensively in the medical industry  They need to be tested for compatibility with spacecraft materials and hardware geometries, and are not yet ready for review Some other methods are of interest as they can sterilize the spacecraft after arrival on the planet 
Supercritical carbon dioxide snow (Mars) - is most effective against traces of organic compounds rather than whole microorganisms  Has the advantage though that it eliminates the organic traces - while other methods kill the microorganisms, they leave organic traces that can confuse life detection instruments  Is under study by JPL and ESA 
Passive sterilization through UV radiation (Mars)  Highly effective against many microorganisms, but not all, as a Bacillus strain found in spacecraft assembly facilities is particularly resistant to UV radiation  Is also complicated by possible shadowing by dust and spacecraft hardware 
Passive sterilization through particle fluxes (Europa)  Plans for missions to Europa take credit for reductions due to this 

Bioburden detection and assessment
The spore count is used as an indirect measure of the number of microorganisms present  Typically 99% of microorganisms by species will be non-spore forming and able to survive in dormant states, and so the actual number of viable dormant microorganisms remaining on the sterilized spacecraft is expected to be many times the number of spore-forming microorganisms 
One new spore method approved is the "Rapid Spore Assay"  This is based on commercial rapid assay systems, detects spores directly and not just viable microorganisms and gives results in 5 hours instead of 72 hours 

Challenges
It is also long been recognized that spacecraft cleaning rooms harbour polyextremophiles as the only microbes able to survive in them  For example, in a recent study, microbes from swabs of the Curiosity rover were subjected to desiccation, UV exposure, cold and pH extremes  Nearly 11% of the 377 strains survived more than one of these severe conditions  The genomes of resistant spore producing Bacillus sp  have been studied and genome level traits potentially linked to the resistance have been reported This does not mean that these microbes have contaminated Mars  This is just the first stage of the process of bioburden reduction  To contaminate Mars they also have to survive the low temperature, vacuum, UV and ionizing radiation during the months long journey to Mars, and then have to encounter a habitat on Mars and start reproducing there  Whether this has happened or not is a matter of probability  The aim of planetary protection is to make this probability as low as possible  The currently accepted target probability of contamination per mission is to reduce it to less than 0 01%, though in the special case of Mars, scientists also rely on the hostile conditions on Mars to take the place of the final stage of heat treatment decimal reduction used for Viking  But with current technology scientists cannot reduce probabilities to zero 

New methods
Two recent molecular methods have been approved for assessment of microbial contamination on 
spacecraft surfaces 
Adenosine triphosphate (ATP) detection - this is a key element in cellular metabolism  This method is able to detect non cultivable organisms  It can also be triggered by non viable biological material so can give a "false positive" 
Limulus Amebocyte Lysate assay - detects lipopolysaccharides (LPS)  This compound is only present in Gram-negative bacteria  The standard assay analyses spores from microbes that are primarily Gram-positive, making it difficult to relate the two methods 

Impact prevention
This particularly applies to orbital missions, Category III, as they are sterilized to a lower standard than missions to the surface  It is also relevant to landers, as an impact gives more opportunity for forward contamination, and impact could be on an unplanned target, such as a special region on Mars 
The requirement for an orbital mission is that it needs to remain in orbit for at least 20 years after arrival at Mars with probability of at least 99% and for 50 years with probability at least 95%  This requirement can be dropped if the mission is sterilized to Viking sterilization standard In the Viking era (1970s), the requirement was given as a single figure, that any orbital mission should have a probability of less than 0 003% probability of impact during the current exploratory phase of exploration of Mars For both landers and orbiters, the technique of trajectory biasing is used during approach to the target  The spacecraft trajectory is designed so that if communications are lost, it will miss the target 

Issues with impact prevention
Despite these measures there has been one notable failure of impact prevention  The Mars Climate Orbiter which was sterilized only to Category III, crashed on Mars in 1999 due to a mix-up of imperial and metric units  The office of planetary protection stated that it is likely that it burnt up in the atmosphere, but if it survived to the ground, then it could cause forward contamination Mars Observer is another Category III mission with potential planetary contamination  Communications were lost three days before its orbital insertion maneuver in 1993  It seems most likely it did not succeed in entering into orbit around Mars and simply continued past on a heliocentric orbit  If it did succeed in following its automatic programming, and attempted the manoeuvre, however, there is a chance it crashed on Mars Three landers have had hard landings on Mars   These are Schiaparelli EDM lander, the Mars Polar Lander, and Deep Space 2  These were all sterilized for surface missions but not for special regions (Viking pre-sterilization only)  Mars Polar Lander, and Deep Space 2 crashed into the polar regions which are now treated as special regions because of the possibility of forming liquid brines 

Controversies
Meteorite argument
Alberto G  Fairén and Dirk Schulze-Makuch published an article in Nature recommending that planetary protection measures need to be scaled down  They gave as their main reason for this, that exchange of meteorites between Earth and Mars means that any life on Earth that could survive on Mars has already got there and vice versa Robert Zubrin used similar arguments in favour of his view that the back contamination risk has no scientific validity 

Rebuttal by NRC
The meteorite argument was examined by the NRC in the context of back contamination  It is thought that all the Martian meteorites originate in relatively few impacts every few million years on Mars  The impactors would be kilometers in diameter and the craters they form on Mars tens of kilometers in diameter  Models of impacts on Mars are consistent with these findings Earth receives a steady stream of meteorites from Mars, but they come from relatively few original impactors, and transfer was more likely in the early Solar System  Also some life forms viable on both Mars and on Earth might be unable to survive transfer on a meteorite, and there is so far no direct evidence of any transfer of life from Mars to Earth in this way 
The NRC concluded that though transfer is possible, the evidence from meteorite exchange does not eliminate the need for back contamination protection methods Impacts on Earth able to send microorganisms to Mars are also infrequent  Impactors of 10 km across or larger can send debris to Mars through the Earth's atmosphere but these occur rarely, and were more common in the early Solar System 

Proposal to end planetary protection for Mars
In their 2013 paper "The Over Protection of Mars", Alberto Fairén and Dirk Schulze-Makuch suggested that we no longer need to protect Mars, essentially using Zubrin's meteorite transfer argument  This was rebutted in a follow up article "Appropriate Protection of Mars", in Nature by the current and previous planetary protection officers Catharine Conley and John Rummel 

Critique of Category V containment measures
The scientific consensus is that the potential for large-scale effects, either through pathogenesis or ecological disruption, is extremely small  Nevertheless, returned samples from Mars will be treated as potentially biohazardous until scientists can determine that the returned samples are safe  The goal is to reduce the probability of release of a Mars particle to less than one in a million 

Policy proposals
Non-biological contamination
A COSPAR workshop in 2010, looked at issues to do with protecting areas from non biological contamination  They recommended that COSPAR expand its remit to include such issues  Recommendations of the workshop include:

Recommendation 3 COSPAR should add a separate and parallel policy to provide guidance on requirements/best practices for protection of non-living/nonlife-related aspects of Outer Space and celestial bodies
Some ideas proposed include protected special regions, or "Planetary Parks" to keep regions of the Solar System pristine for future scientific investigation, and also for ethical reasons 

Proposed extensions
Astrobiologist Christopher McKay has argued that until we have better understanding of Mars, our explorations should be biologically reversible  For instance if all the microorganisms introduced to Mars so far remain dormant within the spacecraft, they could in principle be removed in the future, leaving Mars completely free of contamination from modern Earth lifeforms 
In the 2010 workshop one of the recommendations for future consideration was to extend the period for contamination prevention to the maximum viable lifetime of dormant microorganisms introduced to the planet 

"'Recommendation 4 ' COSPAR should consider that the appropriate protection of potential indigenous extraterrestrial life shall include avoiding the harmful contamination of any habitable environment —whether extant or foreseeable— within the maximum potential time of viability of any terrestrial organisms (including microbial spores) that may be introduced into that environment by human or robotic activity "
In the case of Europa, a similar idea has been suggested, that it is not enough to keep it free from contamination during our current exploration period  It might be that Europa is of sufficient scientific interest that the human race has a duty to keep it pristine for future generations to study as well  This was the majority view of the 2000 task force examining Europa, though there was a minority view of the same task force that such strong protection measures are not required 

"One consequence of this view is that Europa must be protected from contamination for an open-ended period, until it can be demonstrated that no ocean exists or that no organisms are present  Thus, we need to be concerned that over a time scale on the order of 10 million to 100 million years (an approximate age for the surface of Europa), any contaminating material is likely to be carried into the deep ice crust or into the underlying ocean "
In July 2018, the National Academies of Sciences, Engineering, and Medicine issued a Review and Assessment of Planetary Protection Policy Development Processes  In part, the report urges NASA to create a broad strategic plan that covers both forward and back contamination  The report also expresses concern about private industry missions, for which there is no governmental regulatory authority 

Protecting objects beyond the Solar System
The proposal by the German physicist Claudius Gros, that the technology of the Breakthrough Starshot project may be utilized to establish a biosphere of unicellular organisms on otherwise only transiently habitable exoplanets, has sparked a discussion, to what extent planetary protection should be extended to exoplanets  Gros argues that the extended timescales of
interstellar missions imply that planetary and exoplanetary protection have different ethical groundings

Passage 3:
Transit (astronomy)
In astronomy, a transit (or astronomical transit) is a phenomenon when a celestial body passes directly between a larger body and the observer  As viewed from a particular vantage point, the transiting body appears to move across the face of the larger body, covering a small portion of it The word "transit" refers to cases where the nearer object appears smaller than the more distant object  Cases where the nearer object appears larger and completely hides the more distant object are known as occultations 
However, the probability of seeing a transiting planet is low because it is dependent on the alignment of the three objects in a nearly perfectly straight line  Many parameters of  a planet and its parent star can be determined based on the transit 

In the Solar System
One example of a transit involves the motion of a planet between a terrestrial observer and the Sun  This can happen only with inferior planets, namely Mercury and Venus (see transit of Mercury and transit of Venus)  However, because a transit is dependent on the point of observation, the Earth itself transits the Sun if observed from Mars  In the solar transit by the Moon captured during calibration of the STEREO B spacecraft's ultraviolet imaging, the Moon appears much smaller than it does when seen from Earth, because the spacecraft–Moon separation was several times greater than the Earth–Moon distance 
The term can also be used to describe the motion of a satellite across its parent planet, for instance one of the Galilean satellites (Io, Europa, Ganymede, Callisto) across Jupiter, as seen from Earth 
Although rare, cases where four bodies are lined up do happen  One of these events occurred on 27 June 1586, when Mercury transited the Sun as seen from Venus at the same time as a transit of Mercury from Saturn and a transit of Venus from Saturn 

Notable observations
No missions were planned to coincide with the transit of Earth visible from Mars on 11 May 1984 and the Viking missions had been terminated a year previously  Consequently, the next opportunity to observe such an alignment will be in 2084 
On 21 December 2012, the Cassini–Huygens probe, in orbit around Saturn, observed the planet Venus transiting the Sun On 3 June 2014, the Mars rover Curiosity observed the planet Mercury transiting the Sun, marking the first time a planetary transit has been observed from a celestial body besides Earth 

Mutual planetary transits
In rare cases, one planet can pass in front of another  If the nearer planet appears smaller than the more distant one, the event is called a mutual planetary transit 

Outside the Solar System
Exoplanet Detection

The transit method can be used to discover exoplanets  As a planet eclipses/transits its host star it will block a portion of the light from the star  If the planet transits in-between the star and the observer the change in light can be measured to construct a light curve  Light curves are measured with a charge-coupled device  The light curve of a star can disclose several physical characteristics of the planet and star, such as density  Multiple transit events must be measured to determine the characteristics which tend to occur at regular intervals  Multiple planets orbiting the same host star can cause transit-timing variations (TTV)  TTV is caused by the gravitational forces of all orbiting bodies acting upon each other  The probability of seeing a transit from Earth is low, however  The probability is given by the following equation 

  
    
      
        
          P

        a
        ,
      
    
    {\displaystyle P_{\text{transit}}=(R_{\text{star}}+R_{\text{planet}})/a,}
  where Rstar and Rplanet are the radius of the star and planet, respectively, and a is the semi-major axis  Because of the low probability of a transit in any specific system, large selections of the sky must be regularly observed in order to see a transit  Hot Jupiters are more likely to be seen because of their larger radius and short semi-major axis  In order to find Earth-sized planets, red dwarf stars are observed because of their small radius  Even though transiting has a low probability it has proven itself to be a good technique for discovering exoplanets 
In recent years, the discovery of extrasolar planets has prompted interest in the possibility of detecting their transits across their own stellar primaries  HD 209458b was the first such transiting planet to be detected 
The transit of celestial objects is one of the few key phenomena used today for the study of exoplanetary systems  Today, transit photometry is the leading form of exoplanet discovery  As an exoplanet moves in front of its host star there is a dimming in the luminosity of the host star that can be measured  Larger planets make the dip in luminosity more noticeable and easier to detect  Followup observations using other methods are often carried out to ensure it is a planet 
There are currently (December 2018) 2345 planets confirmed with Kepler light curves for stellar host 

Contacts
During a transit there are four "contacts", when the circumference of the small circle (small body disk) touches the circumference of the large circle (large body disk) at a single point   Historically, measuring the precise time of each point of contact was one of the most accurate ways to determine the positions of astronomical bodies   The contacts happen in the following order:

First contact: the smaller body is entirely outside the larger body, moving inward ("exterior ingress")
Second contact: the smaller body is entirely inside the larger body, moving further inward ("interior ingress")
Third contact: the smaller body is entirely inside the larger body, moving outward ("interior egress")
Fourth contact: the smaller body is entirely outside the larger body, moving outward ("exterior egress")A fifth named point is that of greatest transit, when the apparent centers of the two bodies are nearest to each other, halfway through the transit 

Missions
Since transit photometry allows for scanning large celestial areas with a simple procedure, it has been the most popular and successful form of finding exoplanets in the past decade and includes many projects, some of which have already been retired, others in use today, and some in progress of being planned and created  The most successful projects include HATNet, KELT, Kepler, and WASP, and some new and developmental stage missions such as TESS, HATPI, and others which can be found among the List of Exoplanet Search Projects 

HATNet
HATNet Project is a set of northern telescopes in Fred Lawrence Whipple Observatory, Arizona and Mauna Kea Observatories, HI, and southern telescopes around the globe, in Africa, Australia, and South America, under the HATSouth branch of the project  These are small aperture telescopes, just like KELT, and look at a wide field which allows them to scan a large area of the sky for possible transiting planets  In addition, their multitude and spread around the world allows for 24/7 observation of the sky so that more short-period transits can be caught A third sub-project, HATPI, is currently under construction and will survey most of the night sky seen from its location in Chile 

KELT
KELT is a terrestrial telescope mission designed to search for transiting systems of planets of magnitude 8<M<10  It began operation in October 2004 in Winer Observatory and has a southern companion telescope added in 2009  KELT North observes "26-degree wide strip of sky that is overhead from North America during the year", while KELT South observes single target areas of the size 26 by 26 degrees  Both telescopes can detect and identify transit events as small as a 1% flux dip, which allows for detection of planetary systems similar to those in our planetary system 

Kepler / K2
The Kepler satellite served the Kepler mission between 7 March 2009 and 11 May 2013, where it observed one part of the sky in search of transiting planets within a 115 square degrees of the sky around the Cygnus, Lyra, and Draco constellations  After that, the satellite continued operating until 15 November 2018, this time changing its field along the ecliptic to a new area roughly every 75 days due to reaction wheel failure 

TESS
TESS was launched on 18 April 2018, and is planned to survey most of the sky by observing it strips defined along the right ascension lines for 27 days each  Each area surveyed is 27 by 90 degrees  Because of the positioning of sections, the area near TESS's rotational axis will be surveyed for up to 1 year, allowing for the identification of planetary systems with longer orbital periods

Passage 4:
Roche limit
In celestial mechanics, the Roche limit, also called Roche radius, is the distance from a celestial body within which a second celestial body, held together only by its own force of gravity, will disintegrate because the first body's tidal forces exceed the second body's self-gravitation  Inside the Roche limit, orbiting material disperses and forms rings, whereas outside the limit, material tends to coalesce  The Roche radius depends on the radius of the first body and on the ratio of the bodies' densities 
The term is named after Édouard Roche (French: [ʁɔʃ], English:  ROSH), the French astronomer who first calculated this theoretical limit in 1848 

Explanation
The Roche limit typically applies to a satellite's disintegrating due to tidal forces induced by its primary, the body around which it orbits  Parts of the satellite that are closer to the primary are attracted more strongly by gravity from the primary than parts that are farther away; this disparity effectively pulls the near and far parts of the satellite apart from each other, and if the disparity (combined with any centrifugal effects due to the object's spin) is larger than the force of gravity holding the satellite together, it can pull the satellite apart  Some real satellites, both natural and artificial, can orbit within their Roche limits because they are held together by forces other than gravitation  Objects resting on the surface of such a satellite would be lifted away by tidal forces  A weaker satellite, such as a comet, could be broken up when it passes within its Roche limit 
Since, within the Roche limit, tidal forces overwhelm the gravitational forces that might otherwise hold the satellite together, no satellite can gravitationally coalesce out of smaller particles within that limit  Indeed, almost all known planetary rings are located within their Roche limit  (Notable exceptions are Saturn's E-Ring and Phoebe ring  These two rings could possibly be remnants from the planet's proto-planetary accretion disc that failed to coalesce into moonlets, or conversely have formed when a moon passed within its Roche limit and broke apart )
The Roche limit is not the only factor that causes comets to break apart  Splitting by thermal stress, internal gas pressure and rotational splitting are other ways for a comet to split under stress 

Determination
The limiting distance to which a satellite can approach without breaking up depends on the rigidity of the satellite  At one extreme, a completely rigid satellite will maintain its shape until tidal forces break it apart  At the other extreme, a highly fluid satellite gradually deforms leading to increased tidal forces, causing the satellite to elongate, further compounding the tidal forces and causing it to break apart more readily 
Most real satellites would lie somewhere between these two extremes, with tensile strength rendering the satellite neither perfectly rigid nor perfectly fluid  For example, a rubble-pile asteroid will behave more like a fluid than a solid rocky one; an icy body will behave quite rigidly at first but become more fluid as tidal heating accumulates and its ices begin to melt 
But note that, as defined above, the Roche limit refers to a body held together solely by the gravitational forces which cause otherwise unconnected particles to coalesce, thus forming the body in question  The Roche limit is also usually calculated for the case of a circular orbit, although it is straightforward to modify the calculation to apply to the case (for example) of a body passing the primary on a parabolic or hyperbolic trajectory 

Rigid satellites
The rigid-body Roche limit is a simplified calculation for a spherical satellite  Irregular shapes such as those of tidal deformation on the body or the primary it orbits are neglected  It is assumed to be in hydrostatic equilibrium  These assumptions, although unrealistic, greatly simplify calculations 
The Roche limit for a rigid spherical satellite is the distance, 
  
    
      
        d
      
    
    {\displaystyle d}

            M

    {\displaystyle M_{m}}
   is the mass of the secondary 
This does not depend on the size of the objects, but on the ratio of densities  This is the orbital distance inside of which loose material (e g  regolith) on the surface of the satellite closest to the primary would be pulled away, and likewise material on the side opposite the primary will also go away from, rather than toward, the satellite 

Fluid satellites
A more accurate approach for calculating the Roche limit takes the deformation of the satellite into account  An extreme example would be a tidally locked liquid satellite orbiting a planet, where any force acting upon the satellite would deform it into a prolate spheroid 
The calculation is complex and its result cannot be represented in an exact algebraic formula  Roche himself derived the following approximate solution for the Roche limit:

  
    
      
        d
        ≈
        2 44
        R

                  ρ
                  
                    m

Passage 5:
Ulysses (spacecraft)
Ulysses ( yoo-LISS-eez, UK also  YOO-liss-eez) was a robotic space probe whose primary mission was to orbit the Sun and study it at all latitudes  It was launched in 1990 and made three "fast latitude scans" of the Sun in 1994/1995, 2000/2001, and 2007/2008  In addition, the probe studied several comets  Ulysses was a joint venture of the European Space Agency (ESA) and the United States' National Aeronautics and Space Administration (NASA), under leadership of ESA with participation from Canada's National Research Council  The last day for mission operations on Ulysses was 30 June 2009 To study the Sun at all latitudes, the probe needed to change its orbital inclination and leave the plane of the Solar System  To change the orbital inclination of a spacecraft to about 80° requires a large change in heliocentric velocity, the energy to achieve which far exceeded the capabilities of any launch vehicle  To reach the desired orbit around the Sun, the mission's planners chose a gravity assist maneuver around Jupiter, but this Jupiter encounter meant that Ulysses could not be powered by solar cells  The probe was powered instead by a radioisotope thermoelectric generator (RTG) 
The spacecraft was originally named Odysseus, because of its lengthy and indirect trajectory to study the solar poles  It was renamed Ulysses, the Latin translation of "Odysseus", at ESA's request in honor not only of Homer's mythological hero but also of Dante's character in the Inferno  Ulysses was originally scheduled for launch in May 1986 aboard the Space Shuttle Challenger on STS-61-F  Due to the 28 January 1986 loss of Challenger, the launch of Ulysses was delayed until 6 October 1990 aboard Discovery (mission STS-41) 

Spacecraft
The spacecraft was designed by ESA and built by Dornier Systems, a German aircraft manufacturer  The body was roughly a box, approximately 3 2 m × 3 3 m × 2 1 m (10 5 ft × 10 8 ft × 6 9 ft) in size  The box mounted the 1 65 m (5 ft 5 in) dish antenna and the GPHS-RTG radioisotope thermoelectric generator (RTG) power source  The box was divided into noisy and quiet sections  The noisy section abutted the RTG; the quiet section housed the instrument electronics  Particularly "loud" components, such as the preamps for the radio dipole, were mounted outside the structure entirely, and the box acted as a Faraday cage 
Ulysses was spin-stabilised about its z-axis which roughly coincides with the axis of the dish antenna  The RTG, whip antennas, and instrument boom were placed to stabilize this axis, with the spin rate nominally at 5 rpm  Inside the body was a hydrazine fuel tank  Hydrazine monopropellant was used for course corrections inbound to Jupiter, and later used exclusively to repoint the spin axis (and thus, the antenna) at Earth  The spacecraft was controlled by eight thrusters in two blocks  Thrusters were pulsed in the time domain to perform rotation or translation  Four sun sensors detected orientation  For fine attitude control, the S-band antenna feed was mounted slightly off-axis  This offset feed combined with the spacecraft spin introduced an apparent oscillation to a radio signal transmitted from Earth when received on board the spacecraft  The amplitude and phase of this oscillation were proportional to the orientation of the spin axis relative to the Earth direction  This method of determining the relative orientation is called conical scanning and was used by early radars for automated tracking of targets and was also very common in early infrared guided missiles 
The spacecraft used S-band for uplinked commands and downlinked telemetry, through dual redundant 5-watt transceivers  The spacecraft used X-band for science return (downlink only), using dual 20 watts TWTAs until the failure of the last remaining TWTA in January 2008  Both bands used the dish antenna with prime-focus feeds, unlike the Cassegrain feeds of most other spacecraft dishes 
Dual tape recorders, each of approximately 45-megabit capacity, stored science data between the nominal eight-hour communications sessions during the prime and extended mission phases 
The spacecraft was designed to withstand both the heat of the inner Solar System and the cold at Jupiter's distance  Extensive blanketing and electric heaters protected the probe against the cold temperatures of the outer Solar System 
Multiple computer systems (CPUs/microprocessors/Data Processing Units) are used in several of the scientific instruments, including several radiation-hardened RCA CDP1802 microprocessors  Documented 1802 usage includes dual-redundant 1802s in the COSPIN, and at least one 1802 each in the GRB, HI-SCALE, SWICS, SWOOPS and URAP instruments, with other possible microprocessors incorporated elsewhere Total mass at launch was 371 kg (818 lb), of which 33 5 kg was hydrazine propellant used for attitude control and orbit correction 

Instruments
The twelve different Instruments came from ESA and NASA  The first design was based on two probes, one by NASA and one by ESA, but the probe of NASA was defunded and in the end the instruments of the cancelled probe were mounted on Ulyssses 
Radio/Plasma antennas: Two beryllium copper antennas were unreeled outwards from the body, perpendicular to the RTG and spin axis  Together this dipole spanned 72 meters (236 2 ft)  A third antenna, of hollow beryllium copper, was deployed from the body, along the spin axis opposite the dish  It was a monopole antenna, 7 5 meters (24 6 ft) long  These measured radio waves generated by plasma releases, or the plasma itself as it passed over the spacecraft  This receiver ensemble was sensitive from DC to 1 MHz 
Experiment Boom: A third type of boom, shorter and much more rigid, extended from the last side of the spacecraft, opposite the RTG  This was a hollow carbon-fiber tube, of 50 mm (2 in ) diameter  It can be seen in the photo as the silver rod stowed alongside the body  It carried four types of instruments: a solid-state X-ray instrument, composed of two silicon detectors, to study X-rays from solar flares and Jupiter's aurorae; the Gamma-Ray Burst experiment, consisting of two CsI scintillator crystals with photomultipliers; two different magnetometers, a helium vector magnetometer and a fluxgate magnetometer; and a two-axis magnetic search coil antenna measured AC magnetic fields 
Body-Mounted Instruments: Detectors for electrons, ions, neutral gas, dust, and cosmic rays were mounted on the spacecraft body around the quiet section 
Lastly, the radio communications link could be used to search for gravitational waves (through Doppler shifts) and to probe the Sun's atmosphere through radio occultation  No gravitational waves were detected 
Total instrument mass was 55 kg 
Magnetometer (MAG): MAG measured the magnetic field in the heliosphere  Measurements of Jupiter's magnetic field were also performed 
Solar Wind Plasma Experiment (SWOOPS): detected the solar wind at all solar distances and latitudes and in three dimensions  It measured positive ions and electrons 
Solar Wind Ion Composition Instrument (SWICS): determined composition, temperature and speed of the atoms and ions that comprise the solar wind 
Unified Radio and Plasma Wave Instrument (URAP): picked up radio waves from the Sun and electromagnetic waves generated in the solar wind close to the spacecraft 
Energetic Particle Instrument (EPAC) and GAS: EPAC investigated the energy, fluxes and distribution of energetic particles in the heliosphere  GAS studied the uncharged gases (helium) of interstellar origin 
Low-Energy Ion and Electron Experiment (HI-SCALE): investigated the energy, fluxes and distribution of energetic particles in the heliosphere 
Cosmic Ray and Solar Particle Instrument (COSPIN): investigated the energy, fluxes and distribution of energetic particles and galactic cosmic rays in the heliosphere 
Solar X-ray and Cosmic Gamma-Ray Burst Instrument (GRB): studied cosmic gamma ray bursts and X-rays from solar flares 
Dust Experiment (DUST): Direct measurements of interplanetary and interstellar dust grains to investigate their properties as functions of the distance from the Sun and solar latitude 

Mission
Planning
Until Ulysses, the Sun had only been observed from low solar latitudes  The Earth's orbit defines the ecliptic plane, which differs from the Sun's equatorial plane by only 7 25°  Even spacecraft directly orbiting the Sun do so in planes close to the ecliptic because a direct launch into a high-inclination solar orbit would require a prohibitively large launch vehicle 
Several spacecraft (Mariner 10, Pioneer 11, and Voyagers 1 and 2) had performed gravity assist maneuvers in the 1970s  Those maneuvers were to reach other planets also orbiting close to the ecliptic, so they were mostly in-plane changes  However, gravity assists are not limited to in-plane maneuvers; a suitable flyby of Jupiter could produce a significant plane change  An Out-Of-The-Ecliptic mission (OOE) was thereby proposed  See article Pioneer H 
Originally, two spacecraft were to be built by NASA and ESA, as the International Solar Polar Mission  One would be sent over Jupiter, then under the Sun  The other would fly under Jupiter, then over the Sun  This would provide simultaneous coverage  Due to cutbacks, the U S  spacecraft was cancelled in 1981  One spacecraft was designed, and the project recast as Ulysses, due to the indirect and untried flight path  NASA would provide the Radioisotope Thermoelectric Generator (RTG) and launch services, ESA would build the spacecraft assigned to Astrium GmbH, Friedrichshafen, Germany (formerly Dornier Systems)  The instruments would be split into teams from universities and research institutes in Europe and the United States  This process provided the 12 instruments on board 
The changes delayed launch from February 1983 to May 1986 when it was to be deployed by the Space Shuttle Challenger (boosted by the proposed Centaur G Prime upper stage  However, the Challenger disaster forced a two-and-a-half year stand down of the shuttle fleet, mandated the cancellation of the Centaur-G upper stage, and pushed the launch date to October 1990 

Launch
Ulysses was deployed into low Earth orbit from the Space Shuttle Discovery  From there, it was propelled on a trajectory to Jupiter by a combination of solid rocket motors  This upper stage consisted of a two-stage Boeing IUS (Inertial Upper Stage), plus a McDonnell Douglas PAM-S (Payload Assist Module-Special)  The IUS was inertially stabilised and actively guided during its burn  The PAM-S was unguided and it and Ulysses were spun up to 80 rpm for stability at the start of its burn  On burnout of the PAM-S, the motor and spacecraft stack was yo-yo de-spun (weights deployed at the end of cables) to below 8 rpm prior to separation of the spacecraft  On leaving Earth, the spacecraft became the fastest ever artificially-accelerated spacecraft, and held that title until the New Horizons probe was launched 
On its way to Jupiter, the spacecraft was in an elliptical non-Hohmann transfer orbit  At this time, Ulysses had a low orbital inclination to the ecliptic 

Jupiter swing-by
It arrived at Jupiter on 8 February 1992 for a swing-by maneuver that increased its inclination to the ecliptic by 80 2°  The giant planet's gravity bent the spacecraft's flight path southward and away from the ecliptic plane  This put it into a final orbit around the Sun that would take it past the Sun's north and south poles  The size and shape of the orbit were adjusted to a much smaller degree so that aphelion remained at approximately 5 AU, Jupiter's distance from the Sun, and perihelion was somewhat greater than 1 AU, the Earth's distance from the Sun  The orbital period is approximately six years 

Polar regions of the Sun
Between 1994 and 1995 it explored both the southern and northern polar regions of the Sun, respectively 

Comet C/1996 B2 (Hyakutake)
On 1 May 1996, the spacecraft unexpectedly crossed the ion tail of Comet Hyakutake (C/1996 B2), revealing the tail to be at least 3 8 AU in length 

Comet C/1999 T1 (McNaught–Hartley)
An encounter with a comet tail happened again in 2004  when Ulysses flew through the ion tailings of C/1999 T1 (McNaught-Hartley)  A coronal mass ejection carried the cometary material to Ulysses 

Second Jupiter encounter
Ulysses approached aphelion in 2003/2004 and made further distant observations of Jupiter 

Comet C/2006 P1 (McNaught)
In 2007, Ulysses passed through the tail of comet C/2006 P1 (McNaught)  The results were surprisingly different from its pass through Hyakutake's tail, with the measured solar wind velocity dropping from approximately 700 kilometers per second (1,566,000 mph) to less than 400 kilometers per second (895,000 mph) 

Extended mission
ESA's Science Program Committee approved the fourth extension of the Ulysses mission to March 2004  thereby allowing it to operate over the Sun's poles for the third time in 2007 and 2008  After it became clear that the power output from the spacecraft's RTG would be insufficient to operate science instruments and keep the attitude control fuel, hydrazine, from freezing, instrument power sharing was initiated  Up until then, the most important instruments had been kept online constantly, whilst others were deactivated  When the probe neared the Sun, its power-hungry heaters were turned off and all instruments were turned on On 22 February 2008, 17 years and 4 months after the launch of the spacecraft, ESA and NASA announced that the mission operations for Ulysses would likely cease within a few months  On 12 April 2008, NASA announced that the end date will be 1 July 2008 The spacecraft operated successfully for over four times its design life  A component within the last remaining working chain of X-band downlink subsystem failed on 15 January 2008  The other chain in the X-band subsystem had previously failed in 2003 Downlink to Earth resumed on S-band, but the beamwidth of the high gain antenna in the S-band was not as narrow as in the X–band, so that the received downlink signal was much weaker, hence reducing the achievable data rate  As the spacecraft traveled on its outbound trajectory to the orbit of Jupiter, the downlink signal would have eventually fallen below the receiving capability of even the largest antennas (70 meters - 229 7 feet - in diameter) of the Deep Space Network 
Even before the downlink signal was lost due to distance, the hydrazine attitude control fuel on board the spacecraft was considered likely to freeze, as the radioisotope thermal generators (RTGs) failed to generate enough power for the heaters to overcome radiative heat loss into space  Once the hydrazine froze, the spacecraft would no longer be able to maneuver to keep its high gain antenna pointing towards Earth, and the downlink signal would then be lost in a matter of days  The failure of the X-band communications subsystem hastened this, because the coldest part of the fuel pipework was routed over the X-band traveling-wave tube amplifiers, because they generated enough heat during operation to keep the propellant plumbing warm 
The previously announced mission end date of 1 July 2008, came and went but mission operations continued albeit in a reduced capacity  The availability of science data gathering was limited to only when Ulysses was in contact with a ground station due to the deteriorating S-band downlink margin no longer being able to support simultaneous real-time data and tape recorder playback  When the spacecraft was out of contact with a ground station, the S-band transmitter was switched off and the power was diverted to the internal heaters to add to the warming of the hydrazine  On 30 June 2009, ground controllers sent commands to switch to the low gain antennas  This stopped communications with the spacecraft, in combination with previous commands to shut down its transmitter entirely 

Results
During cruise phases, Ulysses provided unique data  As the only spacecraft out of the ecliptic with a gamma-ray instrument, Ulysses was an important part of the InterPlanetary Network (IPN)  The IPN detects gamma ray bursts (GRBs); since gamma rays cannot be focused with mirrors, it was very difficult to locate GRBs with enough accuracy to study them further  Instead, several spacecraft can locate the burst through multilateration  Each spacecraft has a gamma-ray detector, with readouts noted in tiny fractions of a second  By comparing the arrival times of gamma showers with the separations of the spacecraft, a location can be determined, for follow-up with other telescopes  Because gamma rays travel at the speed of light, wide separations are needed  Typically, a determination came from comparing: one of several spacecraft orbiting the Earth, an inner-Solar-system probe (to Mars, Venus, or an asteroid), and Ulysses  When Ulysses crossed the ecliptic twice per orbit, many GRB determinations lost accuracy 
Additional discoveries:
Data provided by Ulysses led to the discovery that the Sun's magnetic field interacts with the Solar System in a more complex fashion than previously assumed 
Data provided by Ulysses led to the discovery that dust coming into the Solar System from deep space was 30 times more abundant than previously expected 
In 2007–2008 data provided by Ulysses led to the determination that the magnetic field emanating from the Sun's poles is much weaker than previously observed 
That the solar wind has "grown progressively weaker during the mission and is currently at its weakest since the start of the Space Age" 

Fate
Ulysses will most likely continue in heliocentric orbit around the Sun indefinitely  However, there is a chance that in one of its re-encounters with Jupiter a close fly-by with one of the Jovian moons would be enough to alter its course and so the probe would enter a hyperbolic trajectory around the Sun and leave the Solar System

Spring soup
Spring soup is a soup made with ingredients that are only in season for a short period during spring  Although asparagus largely characterizes spring soup, spring soup may include just about any spring vegetable added to a broth, chowder, or bisque  Spring soup is popular largely because it includes fresh ingredients not seen for a while by the consumer 

Characteristics
Where winter soups are hearty to "warm and fortify", spring soups aim to celebrate "new skies and freshness" by being "delicate and light, pretty and promising " Spring soups need lighter, brighter tastes and textures than their winter counterparts  A reason for this is that spring soups "capture the essence of the season in a clean-tasting, refreshing broth that showcases the pure flavors" of its ingredients Ingredients used in spring soup include a purée of pea, asparagus, rapini, and fennel, with asparagus being considered the quintessential spring vegetable to largely characterize spring soup  Spring soups typically show a subtle green color to reflect spring 

History
In 1828, The British Almanac provided housekeepers' information to add spring soup to a July menu

Passage 5:
Tidewater region
Tidewater refers to the north Atlantic Plain region of the United States 

Definition
Culturally, the Tidewater region usually includes the low-lying plains of southeast Virginia, northeastern North Carolina, southern Maryland and the Chesapeake Bay  Speaking geographically, however, it covers about 50,000 square miles, from New York's Long Island in the north to the southernmost edge of North Carolina in the south, an area that includes the state of Delaware and the Delmarva Peninsula 
The cultural Tidewater region got its name from the effects of the changing tides on local rivers, sounds, and the ocean  The area has a centuries-old cultural heritage that sets the Tidewater region apart from the adjacent inland parts of the United States, especially with respect to its distinctive dialects of English, which are gradually disappearing, along with its islands and its receding shoreline 

Geography
The tidewater region developed when sea level rose after the last ice age, resulting in the flooding of river valleys in the coastal plain  Such flooded river valleys now make up the tidewater since tides continue to affect water levels far inland, in some cases all the way west to the Fall Line  It is generally flat and low, with large expanses near the tidal shorelines composed of tidal marsh and swamp  Much of the area is covered with pocosin and the higher areas are used for agricultural farmlands  Geographically, in North Carolina and Virginia the Tidewater area is the land between the Suffolk Scarp and the Atlantic Ocean  In Maryland the Tidewater area is the flooded river areas below the Fall Line   The Hampton Roads area of Virginia is considered to be  a Tidewater region   Southern Maryland and the Eastern Shore, parts of Delaware round out the northern part of the region on the Chesapeake and Delaware Bays 
The term tidewater may be correctly applied to all portions of any area, including Virginia, where the water level is affected by the tides (more specifically, where the water level rises when the tide comes in)  In the case of Virginia, the Tidewater region includes the land east of the Fall Line, the natural border with the Piedmont Region  It includes Hampton Roads, the rest of the Virginia Peninsula, the Middle Peninsula, the Northern Neck, and the Eastern Shore 
Planters in the early American colonies extended their tobacco and peanut productions above the Fall Line, where waterfalls or rapids mark the end of the Tidewater and the beginning of the foothill region known as the Piedmont Tidewater is host to flora commonly associated with the South Atlantic pine forests and lower Southeast Coastal Plain maritime flora, the latter found primarily in southeastern Virginia 

Regional accents
A distinctive non-rhotic accent of the Old South was spoken in the Tidewater coastal region of Virginia, best associated with upper-class white speakers of the 19th and early 20th centuries  In the actual islands of the Chesapeake themselves, a separate, rhotic accent survives among the locals, sometimes known as "Hoi Toider"

Peanut soup
Peanut soup or groundnut soup is a soup made from peanuts, often with various other ingredients  It is a staple African cuisine but is also eaten in East Asia (Taiwan), the United States (mainly in Virginia) and other areas around the world  It is also common in some regions, such as Argentina northwest, Bolivia and Peru, where it can sometimes be served with bone meat and hollow short pasta or fries  In Ghana it is often eaten with fufu or omo tuo and is often very spicy  Groundnut soup is also a native soup of the Benin (Edo) people in Nigeria and it is often eaten with pounded yam   Some of the essential ingredients used in making it are Piper guineense (uziza seed) and Vernonia amygdalina (bitter leaf) It is prepared from groundnut which is mashed into a paste, usually termed as groundnut paste  Groundnut soup is eaten with eba, fufu, banku, kenkey and so on  It is a delicacy that Nigerian, Ghanaian and people in other African countries consume, such as in Sierra Leone  In Ghana, it is known as nkatenkwan in Akan language

She-crab soup
She-crab soup is a rich soup, similar to bisque, made of milk or heavy cream, crab or fish stock, Atlantic blue crab meat, and (traditionally) crab roe, and a small amount of dry sherry added as it is plated  It may be thickened either by heat reduction or with a purée of boiled rice; it may also include such seasonings as mace and shallots or onions   The soup is a regional specialty from the South Carolina Lowcountry   It is commonly featured on the menus of many Charleston, South Carolina and Savannah, Georgia restaurants The soup is named for the "she-crab", or female crab, originally a gravid (roe-carrying) crab, as the orange crab roe comprise a chief ingredient in traditional she-crab soup   As with turtle soup, other ingredients may be added to the soup or substituted for others, although crabmeat is found in all versions 
Regulations in Maryland and other states restrict the collection of egg-bearing female crabs

Syodon
Syodon is an extinct genus of dinocephalian therapsids that lived approximately 267-260 million years ago during the middle Permian period of the Paleozoic era  These therapsids, located in Russia  were initially believed to be true mammals   Syodon was first named by Stephan Kutorga in 1838

Question: Which ocean would the ingredients likely come from for the She-crab soup?

The following are given passages.
Context 3:  The fossils of these synapsids were first discovered in the Molotov Province region of Russia in limestone beds with a high content of copper  However, scientists believe that these organisms likely come from higher rock beds due to increased specializations in their morphology 

Etymology
The name Syodon is derived from Greek meaning pig's tooth  This name likely stemmed from the protruding canines similar to that of the lower canines of a wild boar 

Diet
Syodon is characterized as a carnivore, likely feeding on small-bodied prey   They lack the ‘expansion of supraorbital bones over the orbits, which would act as a stress sink’ in certain hypercarniverous species such as thalattosuchian Dakosaurus  This thickened supraorbital regions also found in large theropods would have alleviated cranial stress used for feeding on large prey  Since this adaption is not found in Syodon it is thought they were limited to small animals and prey which they could easily consume with their limited jaw architecture 

Paleobiology
Syodon is characterized by possessing "bulbous" post-canines featuring significant wear facets in adults, whereas juveniles tend to have ‘bladelike’ post canines  The canine of Syodon is highly distinctive and allows it to be distinguished easily  They also possess a large, strongly curved ‘hook-like canine  Syodon also feature a set of smaller, replacement teeth out-of-place from the main palatine tooth row The snout of Syodon is relatively long narrow compared to the rest of the body  The snout comprises approximately 1/4 the length of the skill  These synapsids reached 1 2 m (4 ft) in length

Passage 10:
1996 PW
1996 PW is an exceptionally eccentric trans-Neptunian object and damocloid on an orbit typical of long-period comets but one that showed no sign of cometary activity around the time it was discovered  The unusual object measures approximately 10 kilometers (6 miles) in diameter and has a rotation period of 35 4 hours and likely an elongated shape 

Description
1996 PW orbits the Sun at a distance of 2 5–504 AU once every 4,033 years (semi-major axis of 253 AU)  Its orbit has an eccentricity of 0 99 and an inclination of 30° with respect to the ecliptic Simulations indicate that it has most likely come from the Oort cloud, with a roughly equal probability of being an extinct comet and a rocky body that was originally scattered into the Oort cloud  The discovery of 1996 PW prompted theoretical research that suggests that roughly 1 to 2 percent of the Oort cloud objects are rocky 1996 PW was first observed on 9 August 1996 by the Near-Earth Asteroid Tracking (NEAT) automated search camera on Haleakala Observatory, Hawaii  It is the first object that is not an active comet discovered on an orbit typical of long-period comets 1996 PW has a rotation period of 35 44±0 02 hours and a double-peaked lightcurve with a high amplitude of 0 44±0 03 magnitude (U=3)  Its spectrum is moderately red and featureless, typical of D-type asteroids and bare comet nuclei  Its spectrum suggests an extinct comet  The upper limit on 1996 PW's dust production is 0 03 kg/s
