Shackleton (crater) Shackleton is an impact crater that lies at the south pole of the Moon. The peaks along the crater's rim are exposed to almost continual sunlight, while the interior is perpetually in shadow (a Crater of eternal darkness). The low-temperature interior of this crater functions as a cold trap that may capture and freeze volatiles shed during comet impacts on the Moon. Measurements by the Lunar Prospector spacecraft showed higher than normal amounts of hydrogen within the crater, which may indicate the presence of water ice. The crater is named after Antarctic explorer Ernest Shackleton.
Cape Lankester Cape Lankester ( ) is a high, rounded, snow-covered cape at the south side of the entrance to Mulock Inlet, along the west edge of the Ross Ice Shelf. It was discovered by the British National Antarctic Expedition, 1901–04, and probably named for Sir Edwin Ray Lankester, Director of the British Museum (Natural History) (1898–1907) and founder of the Marine Biological Association in 1884.
