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]
This is a list of designs for crewed lunar landers, spacecraft intended to land on the Moon.A key aspect is achieving a soft landing, and for an ascent stage to successfully escape the Moon's gravity. [1]
The Apollo 13 Lunar Module functioned as a lifeboat to provide life support and propulsion to keep the crew alive for the trip home, when their CSM was disabled by an oxygen tank explosion en route to the Moon. The six landed descent stages remain at their landing sites; their corresponding ascent stages crashed into the Moon following use.
In these six spaceflights, twelve people walked on the Moon. Buzz Aldrin (pictured) walked on the Moon with Neil Armstrong, on Apollo 11, July 20–21, 1969.

Emblem of the Artemis program. The Artemis program is a human spaceflight program by the United States.The Artemis program is intended to reestablish a human presence on the Moon for the first time since Apollo 17 in 1972; mid-term objectives include establishing an international expedition team, and a sustainable human presence on the Moon.
In 1984, with the Space Shuttle in service, a team based at the Johnson Space Center (JSC) made a feasibility study for NASA's return to the Moon.It anticipated later studies in using NASA's planned infrastructure – the Shuttle, a Shuttle-derived heavy lift vehicle, a space station, and an orbital transfer vehicle – to build a permanent 18-crew Moon base sometime between 2005 and 2015.
Each display included Moon dust from Apollo 11 and flags, including one of the Soviet Union, taken along by Apollo 11. The rice-sized particles were four small pieces of Moon soil weighing about 50 mg and were enveloped in a clear acrylic button about as big as a United States half-dollar coin. This acrylic button magnified the grains of lunar ...
