'''Head''' crater is a small crater in [[ |
'''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.<ref name=GPN/> |

[[Apollo 12]] astronauts [[Pete Conrad]] and [[Alan Bean]] landed the [[Apollo Lunar Module|Lunar Module]] (LM) ''Intrepid'' northeast of Head crater on November |
The [[Apollo 12]] astronauts [[Pete Conrad]] and [[Alan Bean]] landed the [[Apollo Lunar Module|Lunar Module]] (LM) ''Intrepid'' northeast of Head crater on November 24, 1969. To the east of Head is the larger [[Surveyor (crater)|Surveyor]] crater. To the southwest are [[Bench (crater)|Bench]] crater and [[Sharp-Apollo (crater)|Sharp]] crater (now called Sharp-Apollo). |
||
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. |

[[Moon rock|Lunar sample]] 12055, a [[pigeonite]] [[basalt]], was collected on the north rim of Head crater.<ref>[https://www.lpi.usra.edu/lunar/samples/atlas/compendium/12055.pdf 12055], Lunar Samples, Lunar and Planetary Institute.</ref> 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 (lunar crater)|Copernicus]] crater and may represent material from the [[Fra Mauro formation]].<ref>[https://www.lpi.usra.edu/lunar/samples/atlas/compendium/12033.pdf 12033], Lunar Samples, Lunar and Planetary Institute.</ref> Sample 12034 is [[regolith]] [[breccia]]. Its composition does not match the other regolith samples from the site and is presumed to have a distant origin.<ref>[https://www.lpi.usra.edu/lunar/samples/atlas/compendium/12034.pdf 12034], Lunar Samples, Lunar and Planetary Institute.</ref> |
