[PAR] [TLE] Shackleton (crater) [SEP] 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. [PAR] [TLE] Ernest Shackleton [SEP] Sir Ernest Henry Shackleton ( ; 15 February 1874 – 5 January 1922) was a polar explorer who led three British expeditions to the Antarctic, and one of the principal figures of the period known as the Heroic Age of Antarctic Exploration.  Born in Kilkea, Athy, County Kildare, Ireland, Shackleton and his Anglo-Irish family moved to Sydenham in suburban south London when he was ten.  His first experience of the polar regions was as third officer on Captain Robert Falcon Scott's Discovery Expedition 1901–1904, from which he was sent home early on health grounds, after he and his companions Scott and Edward Adrian Wilson set a new southern record by marching to latitude 82°S.
