The quarantine requirement was dropped for Apollo 15 and later missions.[1] The LRL was used for study, distribution, and safe storage of the lunar samples. Between 1969 and 1972, six Apollo space flight missions brought back 382 kilograms (842 pounds) of lunar rocks, core samples, pebbles, sand, and dust from the lunar surface—in all, 2,200 samples from six exploration sites.[2] Other lunar samples were returned to Earth by three automated Soviet spacecraft, Luna 16 in 1970, Luna 20 in 1972, and Luna 24 in 1976, which returned samples totaling 300grams (about 3/4 pound).
In 1976, some of the samples were moved to Brooks Air Force Base in San Antonio, Texas, for second-site storage. In 1979, a Lunar Sample Laboratory Facility was built to serve as the chief repository for the Apollo samples: permanent storage in a physically secure and non-contaminating environment. The facility includes vaults for the samples and records, and laboratories for sample preparation and study.[3] The Lunar Receiving Laboratory building was later occupied by NASA's Life Sciences division, contained biomedical and environment labs, and was used for experiments involving human adaptation to microgravity.[4]
In September 2019, NASA announced that the Lunar Receiving Laboratory had not been used for two years and would be demolished.[5][6]
Apollo 11 was the American spaceflight that first landed humans on the Moon. Commander Neil Armstrong and Lunar Module Pilot Buzz Aldrin landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC. Aldrin joined him 19 minutes later, and they spent about two and a quarter hours together exploring the site they had named Tranquility Base upon landing. Armstrong and Aldrin collected 47.5 pounds (21.5 kg) of lunar material to bring back to Earth as pilot Michael Collins flew the Command Module Columbia in lunar orbit, and were on the Moon's surface for 21 hours, 36 minutes before lifting off to rejoin Columbia.
The Apollo program, also known as Project Apollo, was the third United States human spaceflight program carried out by the National Aeronautics and Space Administration (NASA), which succeeded in preparing and landing the first humans on the Moon from 1968 to 1972. It was first conceived in 1960 during President Dwight D. Eisenhower's administration as a three-person spacecraft to follow the one-person Project Mercury, which put the first Americans in space. Apollo was later dedicated to President John F. Kennedy's national goal for the 1960s of "landing a man on the Moon and returning him safely to the Earth" in an address to Congress on May 25, 1961. It was the third US human spaceflight program to fly, preceded by the two-person Project Gemini conceived in 1961 to extend spaceflight capability in support of Apollo.
Apollo 12 was the sixth crewed flight in the United States Apollo program and the second to land on the Moon. It was launched on November 14, 1969, by NASA from the Kennedy Space Center, Florida. Commander Charles "Pete" Conrad and Lunar Module Pilot Alan L. Bean performed just over one day and seven hours of lunar surface activity while Command Module Pilot Richard F. Gordon remained in lunar orbit.
Apollo 14 was the eighth crewed mission in the United States Apollo program, the third to land on the Moon, and the first to land in the lunar highlands. It was the last of the "H missions", landings at specific sites of scientific interest on the Moon for two-day stays with two lunar extravehicular activities.
Apollo 17 was the eleventh and final mission of NASA's Apollo program, the sixth and most recent time humans have set foot on the Moon or traveled beyond low Earth orbit. Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt walked on the Moon, while Command Module Pilot Ronald Evans orbited above. Schmitt was the only professional geologist to land on the Moon; he was selected in place of Joe Engle, as NASA had been under pressure to send a scientist to the Moon. The mission's heavy emphasis on science meant the inclusion of a number of new experiments, including a biological experiment containing five mice that was carried in the command module.
The Lunar Roving Vehicle (LRV) is a battery-powered four-wheeled rover used on the Moon in the last three missions of the American Apollo program during 1971 and 1972. It is popularly called the Moon buggy, a play on the term "dune buggy".
Luna 15 was a robotic space mission of the Soviet Luna programme, that crashed into the Moon on 21 July 1969.
The Apollo Lunar Module, originally designated the Lunar Excursion Module (LEM), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in the airless vacuum of space, and remains the only crewed vehicle to land anywhere beyond Earth.
The Genesis Rock is a sample of Moon rock retrieved by Apollo 15 astronauts James Irwin and David Scott in 1971 during the second lunar EVA, at Spur crater. With a mass of c. 270 grams, it is currently stored at the Lunar Sample Laboratory Facility in Houston, Texas.
A Moon landing or lunar landing is the arrival of a spacecraft on the surface of the Moon. This includes both crewed and robotic missions. The first human-made object to touch the Moon was the Soviet Union's Luna 2, on 13 September 1959.
Moon rock or lunar rock is rock originating from Earth's Moon. This includes lunar material collected during the course of human exploration of the Moon, and rock that has been ejected naturally from the Moon's surface and landed on Earth as meteorites.
A sample-return mission is a spacecraft mission to collect and return samples from an extraterrestrial location to Earth for analysis. Sample-return missions may bring back merely atoms and molecules or a deposit of complex compounds such as loose material and rocks. These samples may be obtained in a number of ways, such as soil and rock excavation or a collector array used for capturing particles of solar wind or cometary debris. Nonetheless, concerns have been raised that the return of such samples to planet Earth may endanger Earth itself.
The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of exploration had been observation from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes; having made his own telescope in 1609, the mountains and craters on the lunar surface were among his first observations using it.
As part of the Apollo 12 mission, the camera from the Surveyor 3 probe was brought back from the Moon to Earth. On analyzing the camera it was found that the common bacterium Streptococcus mitis was alive on the camera. This was attributed by NASA to the camera not being sterilized on Earth prior to its launch two and a half years previously. However, later study showed that the scientists analysing the camera on return to Earth used procedures that were inadequate to prevent recontamination after return to Earth, for instance with their arms exposed, not covering their entire bodies as modern scientists would do. There may also have been possibilities for contamination during the return mission as the camera was returned in a porous bag rather than the airtight containers used for lunar sample return. As a result, the source of the contamination remains controversial.
Third-party evidence for Apollo Moon landings is evidence, or analysis of evidence, about the Moon landings that does not come from either NASA or the U.S. government, or the Apollo Moon landing hoax theorists. This evidence provides independent confirmation of NASA's account of the six Apollo program Moon missions flown between 1969 and 1972.
The mobile quarantine facility (MQF) was a converted Airstream trailer used by NASA to quarantine astronauts returning from Apollo lunar missions for the first few days after splashdown. The MQF was on the aircraft carrier that picked up the capsule. Once the aircraft carrier reached port, the MQF was flown to Houston, and the crew served the remainder of the 21 days of quarantine in the Lunar Receiving Laboratory at the Manned Spacecraft Center. The purpose of the quarantine was to prevent the spread of any contagions from the Moon, though the existence of such contagions was considered unlikely. It functioned by maintaining a lower pressure inside and filtering any air vented.
Of the 270 Apollo 11 Moon rocks and the Apollo 17 Goodwill Moon Rocks that were given to the nations of the world by the Nixon Administration, approximately 180 are unaccounted for. Many of these rocks that are accounted for have been locked away in storage for decades. The location of the rocks has been tracked by researchers and hobbyists because of their rarity and the difficulty of obtaining more. Moon rocks have been subjects of theft and forgery as well.
The Lunar Sample Laboratory Facility (LSLF) is a repository and laboratory facility at NASA's Lyndon B. Johnson Space Center in Houston, Texas, opened in 1979 to house geologic samples returned from the Moon by the Apollo program missions to the lunar surface between 1969 and 1972. The facility preserves most of the 382 kilograms (842 lb) of lunar material returned over the course of Apollo program and other extraterrestrial samples, along with associated data records. It also contains laboratories for processing and studying the samples without contamination.
The Lunar sample displays are two commemorative plaques consisting of small fragments of Moon specimen brought back by the astronauts of the Apollo 11 and Apollo 17 lunar missions. The plaques and Moon rocks were given as goodwill gifts in 1970 and 1973 to the people of 135 countries, the 50 states of the United States, and to U.S. overseas territories by United States President Richard Nixon.
