Rivalries
Nebraska
A traditional college football rivalry with the Nebraska Cornhuskers restarted in the 1980s (many historical documents show the importance of this game going back to 1898) when Bill McCartney declared the conference opponent to be their rival  His theory was since Nebraska was such a powerhouse team, if Colorado was able to beat them then they would be a good team  Colorado began to repeatedly threaten Nebraska in the late 1980s, following their win over the Huskers in 1986, and then surpassed the Huskers for the Big 8 crown in 1989 
In 1990, Colorado beat Nebraska 27–12 in Lincoln for the first time since 1967, en route to their first national title  From 1996 to 2000, the series was extremely competitive, with the margin of victory by NU in those five years being only 15 points combined  The rivalry was further buoyed by the introduction of the Big 12 Conference in 1996, which moved Oklahoma and Oklahoma State to the southern division with the four new schools from Texas, formerly in the Southwest Conference  Nebraska had traditionally finished the Big 8 conference schedule with a rivalry game with Oklahoma, but the two were now in different divisions, which meant they met every other year in the regular season  Colorado replaced Oklahoma as Nebraska's final conference game of the regular season, which further intensified the rivalry  In 2001 No  1 Nebraska came to Folsom Field undefeated and left at the short end of a nationally televised 62–36 blowout  Both teams departed the Big 12 in 2011, as NU headed east to join the Big Ten and the future of the rivalry was in doubt  On February 7, 2013, Colorado and Nebraska agreed to renew the rivalry  Colorado traveled to Lincoln in 2018 and won 33–28 (winning against Nebraska for the first time since 2007 and the first time in Lincoln since 2004)  On September 7, 2019, Colorado mounted an improbable comeback after being down 17–0 at half, to win the game in overtime, 34–31  After a 3-year break, Nebraska will go to Boulder in 2023 and then host CU again the next year to finish the series  Nebraska leads the series 49–20–2 through the 2019 season 

Colorado State
Colorado's in-state rival is the Colorado State Rams of the Mountain West Conference, located north of Boulder in Fort Collins  The two schools are separated by 45 miles (72 km) and both consider it important and noteworthy to beat the other for bragging rights for the next year  The two football teams annually compete in the Rocky Mountain Showdown for the Centennial Cup, played in Denver, Fort Collins, and Boulder  The trophy takes its name from the state of Colorado's nickname of "The Centennial State"  Colorado leads the series 67–22–2 through the 2019 season 

Utah
The rivalry with Utah ran from 1903 to 1962, in which Utah and Colorado played each other nearly every year; through 1962 they had met 57 times  At the time, it was the second-most played rivalry for both teams (Utah had played Utah State 62 times; Colorado had played Colorado State 61 times)  The rivalry was dormant until 2011, when both teams joined the Pac-12, renewing the rivalry on an annual basis  The Colorado–Utah rivalry remains the fifth-most played rivalry in Utah's history, and eighth-most in Colorado's history  Utah leads the series 34-32-3 through the 2022 season 

Bowl games
Colorado has participated in 29 bowl games, with a record of 12–17 ( 414)

Roy Randolph Roundtree (born March 7, 1989) is a former American football wide receiver and current assistant coach for the Grand Valley State Lakers  He was a 2013 preseason member of the Cincinnati Bengals and played college football for the Michigan Wolverines football team where he spent his redshirt senior season with the 2012 team  In 2012, he was an All-Big Ten honorable mention selection  He was a 2011 Fred Biletnikoff Award preseason watchlist honoree  He was a Fred Biletnikoff Award preseason watchlist honoree in 2010, and set Michigan's single-game receiving record with nine catches for 246 yards against Illinois that November  Roundtree was the team's leading receiver in both the 2009 and 2010 seasons  He finished first in the Big Ten Conference in receiving yards in 2010 for Conference games, and was a second team All Conference selection  While in high school, he was named the 2007 Ohio Division II Offensive Player of the Year 

Early life and high school
Roundtree started playing football on the Pee-Wee Dayton Flames in first grade  He played on the team until junior high, joined by his Michigan teammate Michael Shaw, who, because he was eight months older than Roundtree, played in a different level   Roundtree was a two-year starter at Belmont High School in Dayton, Ohio before he transferred to Trotwood-Madison High School, where the team's head football coach was retired National Football League player Maurice Douglass As a freshman, he earned Dayton Daily News Athlete of the Week honors, but in 2004–05, Belmont was classified as an "academic emergency" by the state of Ohio because over a 25% of the students were considered to be "students with disabilities", and the school's standardized test scores were over 50 percent lower than the state benchmarks  With the dismal academic situation and a mediocre athletic program, Belmont left Roundtree dissatisfied, and he transferred to Trotwood before his junior year, where coach Douglass had earned a reputation for developing college ready football players, and where former Flames teammate Domonick Britt was playing quarterback At Trotwood, he was a teammate of Shaw and Brandon Moore who would later join him at Michigan  As a junior in 2006, he posted 48 receptions for 851 yards, and as a senior, he totalled 868 on 52 catches  His four-year totals were 165 receptions for 2,637 yards and 28 touchdowns  As a senior, he was selected to the Division II first-team all-state squad, and named Ohio's offensive player of the year  He was also chosen to play in the Big 33 Football Classic, and ranked as the number 44, 89, and 104 wide receiver in the nation by Rivals com, Scout com, and ESPN, respectively  In that same year, Trotwood won their first playoff game since 1981, led by Roundtree's 13 receptions, 203 yards, and game-winning touchdown  Roundtree feels that his best game in high school was a 12-reception, 221-yard, 2-touchdown performance that helped his team overcome a 21–0 deficit Roundtree had scholarship offers from Eastern Michigan, Illinois, Purdue, Nebraska and Miami  He was considered a Purdue commit until getting a late scholarship offer from Michigan, which was his preferred school  On signing day, his uncle convinced him to go to Michigan because of its winning tradition  The late switch led Purdue head coach Joe Tiller to cast aspersions on Michigan coach Rich Rodriguez, referring to him as a snake oil salesman 

College

College
Mickal was an all-around player; a triple-threat running back who also played on defense  He was regarded as an excellent deep-ball passer; in the words of LSU coach Lawrence "Biff" Jones: "Mickal is a greater passer than Red Cagle—he's the greatest I ever saw " Jones was Cagle's coach while at Army  One sportswriter referred to Mickal as "the Dizzy Dean of the nation's forward passers " He was also known for his play-making ability during crucial moments of games, and LSU compiled a win–loss record of 23–4–5 in the three seasons Mickal played for the team 

1933

Senatorship offer

Dallas Cowboys
Offensive coordinator
In January 2007, Garrett was hired by the Dallas Cowboys as offensive coordinator  He guided the Cowboys to the second-best offense in the NFL, which made him an attractive head coaching prospect  In January 2008, Garrett interviewed for the head coaching job of the Baltimore Ravens and the Atlanta Falcons, receiving offers from both, but ultimately opted to remain with the Cowboys  His salary for the 2008 season was nearly $3 million; the highest salary for an assistant coach in the NFL at the time  On December 29, 2008, the Detroit Lions received permission to speak to Garrett regarding the team's head coaching vacancy according to ESPN sources  In January 2009, the Denver Broncos also interviewed him as a possible replacement for fired coach Mike Shanahan  Garrett was also a finalist for the St  Louis Rams head coaching position to replace Jim Haslett, the interim head coach, but the job ultimately went to Steve Spagnuolo 

Head coach
On November 8, 2010, Garrett was named as interim head coach of the Cowboys after fourth-year head coach Wade Phillips was fired after the Cowboys began the 2010 season with a 1-7 record  On November 14, Garrett won his first game as a head coach, beating the favored New York Giants by a score of 33–20 at New Meadowlands Stadium  The next week, he led the Cowboys to a 35–19 victory over the Detroit Lions, their first home win all season  Garrett finished with a 5–3 record down the stretch  On January 6, 2011, Garrett was officially named the eighth head coach in Cowboys history  He was the first head coach born after the team was founded in 1960, and the first former Cowboys player to hold the post 
From 2011 to 2013, Garrett had three straight 8–8 seasons, losing in the last game each season to NFC East division rivals New York Giants, Washington Redskins, and Philadelphia Eagles to miss the division championship and the playoffs each time  In 2014, Garrett achieved head-coaching success for the first time  The Cowboys, featuring several key draft picks maturing on the offensive line and the emergence of DeMarco Murray as a dominant running back, won the NFC East with a 12–4 record and were tied for the best record in the conference with the Green Bay Packers and the Seattle Seahawks  The Cowboys were undefeated on the road, including impressive wins over Seattle and the NFC East frontrunners (at the time), the Philadelphia Eagles  Garrett's team lost the three-way tiebreaker to Green Bay and Seattle and therefore hosted the Detroit Lions in a wildcard-round game  This game, won 24–20 by the Cowboys, featured a controversial "flag pick up" after a penalty during a late Detroit drive, thereby allowing Dallas an improved chance to make a comeback and defeat the Lions  In the ensuing divisional-round playoff game against the Green Bay Packers, hyped as a rematch of the famous Ice Bowl NFL championship game from 1967, Dallas held a lead in the second half, but after losing the lead due to a late Aaron Rodgers touchdown pass, had a potentially game-winning catch by Dez Bryant overturned in official replay, therefore sealing a 26–21 defeat to Green Bay On January 13, 2015, Cowboys owner Jerry Jones and Garrett agreed on a contract that kept Garrett in Dallas for five more years and paid him $30 million  The Cowboys entered the 2015 season with great expectations, but starting quarterback Tony Romo played in only four games after suffering two fractures in his left collarbone, and the team finished with a 4–12 mark

In 2019, the Cowboys finished with an 8–8 record and missed the playoffs  Toward the end of the season, they had led the NFC East until losing to their division rival, the Philadelphia Eagles in Week 16

Passage 5:
Fake field goal
A fake field goal is a trick play in American football  Simply, it involves a running or passing play done out of a kick formation  Usually the holder (often the punter or backup quarterback) will throw or run  Less frequently, the placekicker, who virtually never handles the ball in an American football game, will serve as the passer or rusher on a fake field goal  
During a fake field goal, most teams will choose one of two different alignment options  The first one is out of the normal field goal formation  The holder receives the snap and can either pitch it to the kicker, throw it during a designed pass play, or run the ball themselves  The second option is to shift into a special formation  Out of these special formations, multiple plays can be brought to the field  
There are a few of advantages to running a fake field goal or extra point  First, if it is a field goal, you have the chance to either score a touchdown or extend a drive for your team  If it is an extra point conversion, you have the chance of scoring two points instead of one  
Danny White was both quarterback and punter for the Dallas Cowboys in the 1980s and often executed this play   Examples include then-New England kicker Adam Vinatieri receiving a direct snap and throwing a touchdown pass during an NFL game in 2004, and LSU kicker Colt David rushing for a 15-yard touchdown in 2007 after receiving the ball on a blind lateral from holder (and starting quarterback) Matt Flynn Not every fake field goal play call results in an attempted trick play  In the Week 8 2014 game between the Indianapolis Colts and Pittsburgh Steelers, the Colts staff had scouted through film study, that the Steelers’ usual kick block formation when the ball was close to the end zone and on the left hash mark, would not be able to prevent the holder from running the ball in for a touchdown  Such a situation developed with one second left on the clock in the second quarter

The following are given passages.
Context 2:   However, instead of lining up a normally, Troy Polamalu, an eight-time Pro-Bowl and 6 time All-Pro safety, shifted from his usual position to the other side, filling the gap where holder Pat McAfee intended to run the ball  McAfee noticed this, and aborted the trick play, calling for Adam Vinatieri to kick a normal kick, which he made to score three points 
Passage 6:
Cornell Green (defensive back)
Cornell M  Green (born February 10, 1940), is an American former professional football player who was  a defensive back for 13 seasons with the Dallas Cowboys on the National Football League (NFL)  He did not play college football at Utah State University, but was a two-time All-American as a basketball player for the Aggies, selected in the 1962 NBA draft, but not in the NFL draft 

Early years
Born in Oklahoma City, Oklahoma, Green was raised in northern California in Richmond and attended El Cerrito High School He played college basketball at Utah State University in Logan, where he earned All-American honors (1961, 1962) as well as All-Skyline conference honors in each of his three years (1960–62)  As a 6 ft 3 in (1 91 m) forward, Green set the Aggie career rebounding record with 1,067 which still stands today  He is also the fifth leading scorer in Utah State history with 1,890 points Green produced some of the best individual seasons in school history as his 745 points in 1962 are still in second place, while his 403 rebounds in 1960 remain a school record for a season  He was the Skyline conference MVP as a sophomore 
In his three seasons with the Aggies, Utah State went to the National Invitation Tournament in 1960 and to the NCAA Tournament in 1962  The 1960 team finished eighth in the Associated Press Poll and seventh in the Coaches' Poll, which remains the highest year-end basketball ranking in school history 
In 1993, Green was inducted into the inaugural class of the Utah State University Intercollegiate Athletics Hall Of Fame  In 2001, he was inducted into the State of Utah Basketball Hall of Fame 

Professional career
Green was a college basketball player who never played a down of college football, that the Dallas Cowboys converted into a defensive back 
On a tip from Utah State basketball coach LaDell Anderson, the Cowboys discovered and signed the multi-talented younger brother of then Red Sox infielder Pumpsie Green for $1,000 dollars  This was one of the innovative personnel decisions the Cowboys were renowned for 
At that time, he was leaning towards playing in the NBA, after being selected by the Chicago Zephyrs in the fifth round of the 1962 NBA draft  Even when he reported to the Cowboys' training camp in Marquette, Michigan, in 1962, he just thought of it as a $1,000 bonus  "I figured I’d go there for a week     and they’d cut me," Green has said His teammates nicknamed him "Sweet Lips" and eventually made the 1962 team as an undrafted free agent, learning fast enough to start 3 games and be selected to the NFL All-Rookie team  The next season, he became a full-time starter at left cornerback setting a career best with 7 interceptions 
Green became a big-time contributor to Tom Landry’s intricate defensive schemes and a feared defender during his career  All he was missing were the interception stats  Said Gil Brandt: "I mean, if Cornell had any kind of hands, he would’ve had three times as many interceptions as he got     and the guy played basketball in college "
He played cornerback during his first eight seasons, while leading the team in interceptions 4 times, being named to 5 Pro Bowls and 4 All-Pro teams  Cowboys coach Tom Landry said of Green, "He had the athletic skills from basketball to become a fine defensive back   His only transition was playing a sport where you could tackle someone with the ball, and Cornell never had a problem dealing with that" 
Safety Mike Gaechter suffered a career-ending Achilles tendon injury in the last Playoff Bowl in January 1970, and with the cornerback position needing an upgrade, Tom Landry moved Mel Renfro to play cornerback  Given that Renfro was an All-Pro in 1969 at safety, the move may have seemed to be an odd one, but Renfro was matched with Herb Adderley, and the duo was better than Green and Phil Clark  Green in turn, moved from cornerback to the strong safety position, while the free safety position was handled between third-round pick Charlie Waters and undrafted free agent Cliff Harris 
After the switch, the Cowboys went to two consecutive Super Bowls  In 1971 and 1972 he went back to the Pro Bowl at safety 
Green never missed a game in 13 seasons, he played 168 games, including 145 consecutive starts for the Cowboys (1962–1974)  He made five Pro Bowls at two different positions — cornerback and strong safety  He is sixth in career interceptions (34) in Cowboys history  He retired as a player in September 1975, and went from part-time to full-time scout for the Cowboys In 1985, he was named to the Dallas Cowboys 25th Anniversary Team In 2017, the Professional Football Researchers Association named Green to the PFRA Hall of Very Good Class of 2017

After football
Green began scouting for the Dallas Cowboys in 1970 while still an active player and continued scouting through 1979, at which time he entered private business until joining the Denver Broncos in 1987  He spent 35 years scouting in the NFL, and 28 seasons doing it with the Broncos  In 2010, he received the AFC Scout of the Year Award from the Fritz Pollard Alliance

In a memorable 1980 playoff game against the Atlanta Falcons, led the Cowboys to a come-from-behind 30–27 victory  He also played in one of the Cowboys' most painful playoff losses against the San Francisco 49ers in the 1981 NFC Championship Game, famous for the Joe Montana-to-Dwight Clark game-winning play, which would simply come to be known as "The Catch"  He received Pro Bowl and second-team All-Pro honors in 1982 
White led the Cowboys to three consecutive NFC Championship Games (1980–1982), but was criticized after the Cowboys lost each of the three games despite having been favored in all of them  He also received criticism for publicly siding with the owners during the 1982 NFL Players Strike  Fans and teammates alike began to show support for him to be replaced as the Cowboys quarterback by Gary Hogeboom, who was coming off an impressive performance in the 1982 NFC Championship Game (which they lost to the archrival Washington Redskins) after White was knocked out of the game with a concussion  Even his statistically career-best 1983 season failed to silence the critics, after ending it with consecutive blowout losses to the Redskins (at home) and the 49ers after a 12–2 start  To add insult to injury, the Cowboys lost the NFC Wildcard Playoff game to the Los Angeles Rams  That apparently was enough for him to lose his starting job to Hogeboom at the start of the 1984 season  Under Hogeboom, the Cowboys looked impressive with a 4–1 start, but then a loss to division rival St  Louis and ineffective plays by Hogeboom convinced coach Tom Landry to reinstate White as his starter  The Cowboys finished 9–7, but missed the playoffs in 1984 for the first time in a decade; but with White as quarterback, the Cowboys made it back in 1985 with a 10–6 record  However, they lost again to the Los Angeles Rams in the playoffs 
In 1986, the Cowboys started 6–2, had the #1 offense in the NFL, were tied for the lead in the NFC Eastern Division and White was also the number one rated passer in the NFC at that point in the season  During an away game against Bill Parcells's New York Giants, however, a blind-side sack by Giants linebacker Carl Banks broke White's throwing wrist and tore ligaments, knocking him out of the game and ending his season  Dallas lost the game, 17–14, and without him the team faded badly, finishing the year 7–9 and the Cowboys first losing season since 1965 
White returned as the starter at the beginning of 1987, but after inconsistent play, he was benched in favor of Steve Pelluer for 4 of the final 6 games  In 1988, Pelluer won the starting job in training camp, relegating White as a backup  White appeared briefly in only two games, and in his second game he suffered a season-ending knee injury  An option on his contract was not picked up in April 1989 and he retired, paving the way for Troy Aikman to take the reins of the struggling franchise 
White had 1,761 completions on 2,950 attempts for 21,959 yards, 155 touchdowns, and 132 interceptions in his career   He also gained  482 yards and scored 8 touchdowns rushing  Unusual for a quarterback, he had two pass receptions for touchdowns, both from a halfback option pass  On special teams he punted 610 times for 24,509 yards, an average of 40 4 yards per punt, with 144 punts inside the 20 and 77 touchbacks  His record as the Cowboys' starting quarterback was 62–32 ( 659 winning percentage) during the regular season, and 5–5 in the playoffs 
Being Roger Staubach's successor and never reaching a Super Bowl as a starting quarterback contributed to White's being an unappreciated player, even considering all of the successes he achieved for the Cowboys and the NFL during the decade of the eighties  "I don't think anybody could have followed Roger and done as well as Danny", Coach Tom Landry remarked, "Danny was a solid winner "

Regular season
Coaching career
White's career as a coach began shortly after his playing days ended  This is appropriate considering that, while an active player, he was widely regarded—like Staubach before him—as knowledgeable of the game and as something of a coach on the field  He also began working as a broadcast commentator during his coaching career, which was possible because he coached Arena football, which is played during the outdoor game's off-season 
White served as the head coach of the Arizona Rattlers from 1992 to 2004, winning the ArenaBowl championship in 1994 and 1997  White's contract was not renewed by the new Rattlers ownership after the 2004 season following three consecutive ArenaBowl losses  He was named the head coach of the Arena Football League expansion Utah Blaze, which began play in 2006  He led his teams to the playoffs in 10 of 11 seasons, including two championships (1994 and 1997), finishing with a 162–95 record as a head coach 
In 2002, he was inducted into the Arena Football League Hall of Fame in recognition for his coaching success 

Head coaching record
Personal life
White's father, Wilford "Whizzer" White (no relation to college football legend and U S  Supreme Court justice Byron White, who also was nicknamed "Whizzer" and played American football), was the first Arizona State University All-American football player and still ranks third in school history with 1502 rushing yards in a season (1950), he also played halfback for the Chicago Bears from 1951–52 In 1983, White briefly recorded as a country music artist for the Grand Prix label  His only single, "You're a Part of Me", a duet with Linda Nail, reached #85 on the Hot Country Songs charts White and his wife, JoLynn, have four children, Ryan (d  2015), Geoff, Heather and Reed, and sixteen grandchildren  He now makes corporate appearances and motivational speeches  JoLynn died on August 15, 2016  White is currently married to Linda L  Bang  In recent years he has been seen on TV doing ADT security infomercials White is a member of the Church of Jesus Christ of Latter-day Saints

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

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:

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

Passage 6:
The Feast at Solhaug
The Feast at Solhaug (or in the original Norwegian Gildet paa Solhoug) is the first publicly successful drama by Henrik Ibsen  It was written in 1855 and had its premier at Det norske Theater in Bergen on 2 January 1856  Part of the strength and charm of this play as well as Ibsen's other early poetic works results from the style of the poetic form and the inherent melody of the old ballads for those who speak Scandinavian languages 

Plot
The play opens on the day of the feast celebrating the third wedding anniversary of the marriage of Bengt Gauteson and Margit  Erik of Hogge, a friend of Knut Gesling, the King's sheriff, and Knut himself are seeking permission for Knut to marry Margit's sister, Signe  Knut, a warlike man, is advised that he must demonstrate peaceful ways for a year before Margit will support the marriage  They are invited to the feast, under pledge that they will be peaceful that night 
They depart to look for Margit's kinsman, Gudmund Alfson, who they know to be outlawed and suspect to be nearby  Once they depart and her husband leaves, Margit speaks of her regret in marrying Bengt Gauteson, even though he was a wealthy older landowner  Her woe is captured by her phrase, "I myself am the Hill-King's wife!"
Gudmund Alfson arrives  Margit, who has loved him since he departed three years earlier, treats him poorly until she realizes that, although once close to the king, he has been outlawed and is on the run  She then dreams of marrying him and obtains poison to administer to Bengt 
Meanwhile, Gudmund speaks to Signe, who has grown up since he last saw her, expressing his love  Signe remembers him well and is most willing 
Knut returns in the evening for the feast  Finding Gudmund there, although he is the sheriff, Knut does not take Gudmund to demonstrate his intent to be peaceful, but declares that this day shall end peacefully 
They both speak together, expressing their intent to marry  After some discussion they both proclaim, and realize they woo the same woman  Since Signe loves Gudmund, Knut announces he is leaving peacefully, but will return in the morn to take Gudmund 
Magrit prepares to poison Bengt after many of the guests depart, leaving him a poisoned drink as she goes to bed  He is advised of Knut’s return and, setting aside his drink, goes to meet Knut and his men  Gudmund & Signe enter and almost drink the poison 
As Knut returns in the morning and meets Bengt who is set upon defending his household, Knut slays him  Bengt’s friends capture Knut and bring him before Margit 
The king’s men arrive  Gudmund is prepared to surrender, but finds that the king has recognized his error and restored all of Gudmund’s property and standing 
Margit wishes Gudmund and Signe well and goes off to St  Sunniva's cloister
