Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. Its detailed mapping program is identifying safe landing sites, locating potential resources on the Moon, characterizing the radiation environment, and demonstrating new technologies. Launched on June 18, 2009, in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, LRO was the first United States mission to the Moon in over ten years. LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program. The probe has made a 3-D map of the Moon's surface at 100-meter resolution and 98.2% coverage (excluding polar areas in deep shadow), including 0.5-meter resolution images of Apollo landing sites. The first images f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mare Cognitum
Mare Cognitum (Latin ''cognitum'', the "Sea that has Become Known") is a lunar mare located in a basin or large crater which sits in the second ring of Oceanus Procellarum. To the northwest of the mare is the Montes Riphaeus mountain range, part of the rim of the buried crater or basin containing the mare. Previously unnamed, the mare received its name in 1964 in reference to its selection as the target for the successful impact probe Ranger 7, the first American spacecraft to return closeup images of the Moon's surface. Origin The basin material is of the Pre-Nectarian epoch, while most of the basaltic mare material is of the Upper Imbrian epoch. Exploration The Ranger 7 lunar probe impacted Mare Cognitum at the conclusion of its picture-taking mission. Surveyor 3 and Apollo 12 landed near its northern shore. The outcrop of the Fra Mauro formation, where Apollo 14 landed, is also located near Mare Cognitum. Statio Cognitum On November 19, 1969, astronauts Pete Conrad and Al ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo 12
Apollo 12 (November 14–24, 1969) 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 Pete Conrad, Charles "Pete" Conrad and Lunar Module Pilot Alan Bean, Alan L. Bean performed just over one day and seven hours of lunar surface activity while Command Module Pilot Richard F. Gordon Jr., Richard F. Gordon remained in lunar orbit. Apollo 12 would have attempted the first lunar landing had Apollo 11 failed, but after the success of Neil Armstrong's mission, Apollo 12 was postponed by two months, and other Apollo missions also put on a more relaxed schedule. More time was allotted for geologic training in preparation for Apollo 12 than for Apollo 11, Conrad and Bean making several geology field trips in preparation for their mission. Apollo 12's spacecraft and launch vehicle were almost identical to Apollo 11's. One addition was hammocks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pete Conrad
Charles "Pete" Conrad Jr. (June 2, 1930 – July 8, 1999) was an American NASA astronaut, aeronautical engineer, naval officer and aviator, and test pilot, and commanded the Apollo 12 space mission, on which he became the third person to walk on the Moon. Conrad was selected in NASA's second astronaut class in 1962. Conrad had dyslexia and yet earned his Bachelor of Science degree in Aerospace engineering, Aeronautical Engineering from Princeton University—being the first Ivy League astronaut—and joined the U.S. Navy. In 1954 he received his naval aviator wings, served as a fighter pilot and, after graduating from the United States Naval Test Pilot School, U.S. Naval Test Pilot School (Class 20), as a project test pilot. In 1959 he was an astronaut candidate for Project Mercury. Conrad set an eight-day space endurance record in 1965 along with his Command Pilot Gordon Cooper on his first spaceflight, Gemini 5. Later, Conrad commanded Gemini 11 in 1966, and Apollo 12 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alan Bean
Alan LaVern Bean (March 15, 1932 – May 26, 2018) was an American naval officer and aviator, aeronautical engineer, test pilot, NASA astronaut and painter; he was the fourth person to walk on the Moon. He was selected to become an astronaut by NASA in 1963 as part of Astronaut Group 3. Before becoming an astronaut, Bean graduated with a Bachelor of Science degree in Aeronautical Engineering from University of Texas at Austin in 1955 and re-joined the U.S. Navy—he served as an enlisted member for a year after his high school graduation. He received his naval aviator wings in 1956 and served as a fighter pilot. In 1960, he graduated from the U.S. Naval Test Pilot School, flew as a test pilot and was The New Nine selection finalist in 1962. He made his first flight into space aboard Apollo 12, the second crewed mission to land on the Moon, at age 37 in November 1969.

Apollo Lunar Module
The Apollo Lunar Module (LM ), 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. Structurally and aerodynamically incapable of flight through Earth's atmosphere, the two-stage lunar module was ferried to lunar orbit attached to the Apollo command and service module (CSM), about twice its mass. Its crew of two flew the complete lunar module from lunar orbit to the Moon's surface. During takeoff, the spent descent stage was used as a launch pad for the ascent stage which then flew back to the command module, after which it was also discarded. Overseen by Grumman, the LM's development was plagued with problems that delayed its first uncrewed flight by about ten months and its first crewed ...

Surveyor (crater)
Surveyor crater is a small crater in Mare Cognitum on the Moon. The name of the crater was formally adopted by the IAU in 1973. On April 20, 1967, the Surveyor 3 spacecraft landed within the crater near the east rim. Surveyor 3 was the third lander of the American unmanned Surveyor program sent to explore the surface of the Moon. The Apollo 12 astronauts Pete Conrad and Alan Bean landed the Lunar Module (LM) ''Intrepid'' north of Surveyor crater on November 19, 1969, and eventually walked over to Surveyor 3. During their descent, Surveyor crater was a major landmark, and is the largest crater at the landing site. To the west of Surveyor is Head crater. To the southwest are Bench crater and Sharp crater (now called Sharp-Apollo). To the south is Halo Halo, halos or haloes usually refer to: * Halo (optical phenomenon) * Halo (religious iconography), a ring of light around the image of a head HALO, halo, halos or haloes may also refer to: Arts and entertainment Video gam ...

Head (crater)
Head crater is a small crater in Mare Cognitum on the Moon. The name of the crater was formally adopted by the IAU in 1973. The Apollo 12 astronauts Pete Conrad and Alan Bean landed the Lunar Module (LM) ''Intrepid'' northeast of Head crater on November 24, 1969. To the east of Head is the larger Surveyor crater. To the southwest are Bench crater and Sharp crater (now called Sharp-Apollo). To the northwest of Head is the larger crater Middle Crescent. It is called ''Head'' because the pattern of craters in the area resembles that of a snowman (with Surveyor crater forming the body) when viewed from the east, as in the landing approach. Samples Lunar sample 12055, a pigeonite basalt, was collected on the north rim of Head crater. The crew dug a small trench about 15 m inside the northwest rim of Head crater. Soil samples 12033 and 12034 were collected from it. 12033 is a ropy glass sample that has been suggested came from Copernicus crater and may represent material from ...
