Description:
Diviner Lunar Radiometer Experiment surface-temperature maps reveal the existence of widespread surface and near-surface cryogenic regions that extend beyond the boundaries of persistent shadow. The Lunar Crater Observation and Sensing Satellite (LCROSS) struck one of the coldest of these regions, where subsurface temperatures are estimated to be 38 kelvin. Large areas of the lunar polar regions are currently cold enough to cold-trap water ice as well as a range of both more volatile and less volatile species. The diverse mixture of water and high-volatility compounds detected in the LCROSS ejecta plume is strong evidence for the impact delivery and cold-trapping of volatiles derived from primitive outer solar system bodies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paige, David A -- Siegler, Matthew A -- Zhang, Jo Ann -- Hayne, Paul O -- Foote, Emily J -- Bennett, Kristen A -- Vasavada, Ashwin R -- Greenhagen, Benjamin T -- Schofield, John T -- McCleese, Daniel J -- Foote, Marc C -- DeJong, Eric -- Bills, Bruce G -- Hartford, Wayne -- Murray, Bruce C -- Allen, Carlton C -- Snook, Kelly -- Soderblom, Laurence A -- Calcutt, Simon -- Taylor, Fredric W -- Bowles, Neil E -- Bandfield, Joshua L -- Elphic, Richard -- Ghent, Rebecca -- Glotch, Timothy D -- Wyatt, Michael B -- Lucey, Paul G -- New York, N.Y. -- Science. 2010 Oct 22;330(6003):479-82. doi: 10.1126/science.1187726.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Space Sciences, University of California, Los Angeles, 595 Charles E.
