In July 1962, eleven firms were invited to submit proposals for the LEM. Nine companies responded in September, answering 20 questions posed by the NASA RFP in a 60-page limited technical proposal. Grumman was awarded the contract officially on November 7, 1962. [12] Grumman had begun lunar orbit rendezvous studies in the late 1950s and again ...
The design and development of ICUBE-Q was a collaborative effort between Institute of Space Technology (IST), Pakistan's national space agency SUPARCO, and China's Shanghai Jiao Tong University (SJTU). IST has been developing several CubeSat in the same series of which iCube-1 was successfully launched in 2013. [7] [13] [14]
The locations of lunar retroreflectors left by Apollo (A) and Luna (L) missions. Retroreflectors are devices which reflect light back to its source. Six were left at six sites on the Moon by three crews of the Apollo program, two by remote landers of the Lunokhod program, and one by the Chandrayaan program. [1]
Materials on the Moon's surface contain helium-3 at concentrations estimated between 1.4 and 15 parts per billion (ppb) in sunlit areas, [1] [63] [64] and may contain concentrations as much as 50 ppb in permanently shadowed regions. [65] For comparison, helium-3 in the Earth's atmosphere occurs at 7.2 parts per trillion (ppt).
Moon landing deniers say there's clear photographic evidence of this, and point out that because there's no breeze on the moon, this must be fake. Apollo 11astronaut Edwin Buzz Aldrin, on the Moon ...
[2] Objects at greater than 90 degrees east or west are on the far side of the Moon, including Ranger 4, Lunar Orbiter 1, Lunar Orbiter 2, Lunar Orbiter 3, Chang'e 4 lander and Yutu-2 rover. Because of increasing numbers of missions to and objects at the Moon, a global registry of lunar activities has been proposed in 2023 by the Open Lunar ...

The orbits of the Moon and planets are integrated numerically along with the orientation of the Moon called physical libration. [23] At the Moon's surface, the beam is about 6.5 kilometers (4.0 mi) wide [24] [i] and scientists liken the task of aiming the beam to using a rifle to hit a moving dime 3 kilometers (1.9 mi) away. The reflected light ...
