The lunar crater Archimedes is 82 kilometers (50 miles) wide and is located at 29.7o North, 4.0o West. Its two smaller companion craters are Aristillus and Autolycus, named after two Greek astronomers of the third century BC. It is the largest crater inside the Mare Imbrium (Sea of Showers), which is outlined along the southeast by the Apennine Mountains. The crater floor is filled with smooth mare material and its ejecta blanket, which forms the Montes Archimedes, is below it. Several long fissures emanating from its southern rim and proceeding southeast are known as the Rimae Archimedes.


Luna 2

The closest man-made object to Archimedes Crater is Luna 2, which is also the first man-made object to land on the moon. Luna 2 was the second of a series of spacecraft launched by the Soviet Union to explore the moon. Its 390-kilogram instrument package crashed on the surface of the moon on September 14, 1959, between the Archimedes and Autolycus Craters at roughly 0o longitude, 29.1o North latitude.

Apollo 15

The closest humans have come to Archimedes Crater was during the Apollo 15 mission, whose landing site was at the base of the Apennine Mountains about 200 kilometers southeast of the crater's center. Details of the mission are below:

Launched: 26 July 1971
Landed on Moon: 30 July 1971
Landing Site: 26.10o North, 3.65o East
Returned to Earth: 7 August 1971
