IMPACT CRATER MODIFICATION IN UTOPIA PLANITIA, NORTHERN PLAINS OF MARS

, 2010
The meteorite impact crater record on Mars has been the subject of much research following the substantial volume of remote sensing data returned by satellite missions over the last decade. The impact crater record in Utopia Planitia, one the great northern plains of Mars, is of particular interest because the region is a potential hub of late ...

Present-day Exposures of Water Ice in the Northern Mid-latitudes of Mars [PDF]

Water ice is exposed in the martian north polar cap, but is rarely exposed beyond the cap boundary. Orbital gamma ray spectrometry data strongly imply the presence of water ice within meters of the surface at latitudes north of approximately 60deg.
