Most lunar meteorites are launched from the Moon by impacts making lunar craters of a few kilometers in diameter or less. [6] No source crater of lunar meteorites has been positively identified, although there is speculation that the highly anomalous lunar meteorite Sayh al Uhaymir 169 derives from the Lalande impact crater on the lunar nearside.

Lunar Sample 14321, better known as "Big Bertha", is a lunar sample containing an embedded Earth-origin meteorite collected on the 1971 Apollo 14 mission. It was found in the Fra Mauro region of the Moon. Big Bertha is the first discovered meteorite from Earth, and the embedded meteorite portion is the oldest known Earth rock.
The rotational axis of the Moon passes through Shackleton, near the rim. The crater is 21 km (13 miles) in diameter and 4.2 km (2.6 miles) deep. [2] From the Earth, it is viewed edge-on in a region of rough, cratered terrain. It is located within the South Pole–Aitken basin on a massif. [3]
During the 1960s, rectified images of Mare Orientale by Gerard Kuiper at the Lunar and Planetary Laboratory gave rise to the notion of it being an impact crater. [3] [4] The structure, with the flat plain of the mare in the center, is about 900 kilometres (560 mi) across and was formed by the impact of an asteroid-sized object, [5] [6] possibly 64 km (40 mi) in diameter and travelling at 15 km ...
The moon has been constantly bombarded by meteorites - early in its history by large ones that gashed the gaping craters visible on the lunar surface and more recently by smaller ones including ...

The Moon is the only extraterrestrial body for which we have samples with a known geologic context. A handful of lunar meteorites have been recognized on Earth, though their source craters on the Moon are unknown. A substantial portion of the lunar surface has not been explored, and a number of geological questions remain unanswered.
