Thirty-two astronauts were assigned to fly in the Apollo manned lunar landing program.
 Twenty-four of them left Earth's orbit and flew around the Moon on nine missions.
 (Of the other manned missions, Apollo 1 did not launch and Apollo 7 and Apollo 9 were low Earth orbit spacecraft testing missions).
 In addition, nine astronauts flew Apollo spacecraft in the Apollo Applications Programs Skylab and Apollo–Soyuz Test Project.
Francis Albert Sinatra ( ; ] ; December 12, 1915 – May 14, 1998) was an American singer, actor, and producer who was one of the most popular and influential musical artists of the 20th century.
 He is one of the best-selling music artists of all time, having sold more than 150 million records worldwide.
 Born in Hoboken, New Jersey, to Italian immigrants, Sinatra began his musical career in the swing era with bandleaders Harry James and Tommy Dorsey.
 Sinatra found success as a solo artist after he signed with Columbia Records in 1943, becoming the idol of the "bobby soxers".
 He released his debut album, "The Voice of Frank Sinatra", in 1946.
 Sinatra's professional career had stalled by the early 1950s, and he turned to Las Vegas, where he became one of its best known performers as part of the Rat Pack.
 His career was reborn in 1953 with the success of "From Here to Eternity", with his performance subsequently winning an Academy Award and Golden Globe Award for Best Supporting Actor.
 Sinatra released several critically lauded albums, including "In the Wee Small Hours" (1955), "Songs for Swingin' Lovers!
" (1956), "Come Fly with Me" (1958), "Only the Lonely" (1958) and "Nice 'n' Easy" (1960).
"Fly Me to the Moon", originally titled "In Other Words", is a song written in 1954 by Bart Howard.
 Kaye Ballard made the first recording of the song in 1954.
 Since then it has become a frequently recorded jazz standard often featured in popular culture; Frank Sinatra's 1964 version was closely associated with the Apollo missions to the Moon, and the Japanese animated series "Neon Genesis Evangelion" played the song (as covered by various artists) at the end of every episode.
The Compton–Belkovich Thorium Anomaly is a hotspot (volcanic complex) on the Moon.
 It is on the far side of the Moon and was found by a gamma-ray spectrometer in 1998.
 It is an area of concentrated thorium, a radioactive element.
 Lunar rock samples from the Apollo missions reveal that most lunar volcanism occurred around 3 to 4 billion years ago, but could have been as recent as 1 billion years ago due to the unknown history of the moon's far side.
Lunar Escape Systems (LESS) were a series of emergency vehicles designed for never-flown long-duration Apollo missions. Because these missions were even more hypothetical than the planned cancelled Apollo missions, the designs were never constructed.
 This concept was an outgrowth of the Lunar Flying Vehicle designed by Bell Aerospace (a lunar surface mobility design that was cancelled in favor of the less risky Lunar Rover).
Frank Sinatra's Greatest Hits!
 is Frank Sinatra's first compilation released on his own Reprise Records.
 It concentrates on mostly single releases from the mid to late 60's, which fluctuates between adult contemporary pop and jazzy swing.
 The album opens up with Sinatra's recent number one hit "Strangers in the Night" and continues through the varied styles of music Sinatra recorded in the 60's, from easy listening ballads like "It Was a Very Good Year" and "Softly, as I Leave You" to contemporary pop like "When Somebody Loves You" and "That's Life".
 "Greatest Hits" was a modest hit, peaking at #55 on the album charts in late 1968.
 A second volume was issued in 1972, "Frank Sinatra's Greatest Hits, Vol.
 2".
 Both albums have since been supplanted with newer and more cohesive compilations.
Stainless steel commemorative plaques measuring 9 by were attached to the ladders on the descent stages of the United States Apollo Lunar Modules flown on lunar landing missions Apollo 11 through Apollo 17, to be left permanently on the lunar surface.
 The plaques were originally suggested and designed by NASA's head of technical services Jack Kinzler, who oversaw their production.
 All of the plaques bear facsimiles of the participating astronauts' signatures.
 For this reason, an extra plaque had to be made for Apollo 13 due to the late replacement of one crewmember.
 The first (Apollo 11) and last (Apollo 17) plaques bear a facsimile of the signature of Richard Nixon, President of the United States during the landings, along with references to the start and "completion" of "man's" "first" explorations of the Moon and expressions of peace for "all mankind".
 All, except the Apollo 12 plaque (which is also textured differently), bear pictures of the two hemispheres of Earth.
 Apollo 17's plaque bears a depiction of the lunar globe in addition to the Earth.
 The plaques used on missions 13 through 16 bear the call-sign of each mission's Lunar Module.
 All the plaques were left on the Moon, except the two for the aborted Apollo 13 which did not land on the Moon.
The Apollo Lunar Surface Experiments Package (ALSEP) comprised a set of scientific instruments placed by the astronauts at the landing site of each of the five Apollo missions to land on the Moon following Apollo 11 (Apollos 12, 14, 15, 16, and 17).
 Apollo 11 left a smaller package called the Early Apollo Scientific Experiments Package, or EASEP.
"Apollo 21" is an apocryphal reference to an eleventh manned Moon landing mission of NASA's Apollo program.
 Apollo contracted for the construction of fifteen Saturn V launch vehicles used to launch the Apollo spacecraft to the Moon, and achieved the first manned landing with the sixth one (Apollo 11), leaving nine for follow-on lunar missions, through Apollo 20.
 However, budget cuts caused NASA to cancel the last three missions, ending the lunar program after Apollo 17.
 One Saturn V was used to launch the Skylab space station, and parts of the other two became museum displays.
The Lunex Project was a US Air Force 1958 plan for a manned lunar landing prior to the Apollo Program.
 The final lunar expedition plan in 1961 was for a 21-airman underground Air Force base on the Moon by 1968 at a total cost of $7.5 billion.
 The primary distinction between the later Apollo missions and Lunex was the orbital rendezvous maneuver.
 The Lunex vehicle, composed of a landing module and a lifting body return/re-entry module, would land the entire vehicle and all astronauts on the surface, whereas the final Apollo mission involved a separate ascent module leaving the command module and service module connected in lunar orbit with a single astronaut.
 The original plan for Apollo was for direct ascent, similar to Lunex.
