Description:
The martian subsurface has been probed to kilometer depths by the Mars Advanced Radar for Subsurface and Ionospheric Sounding instrument aboard the Mars Express orbiter. Signals penetrate the polar layered deposits, probably imaging the base of the deposits. Data from the northern lowlands of Chryse Planitia have revealed a shallowly buried quasi-circular structure about 250 kilometers in diameter that is interpreted to be an impact basin. In addition, a planar reflector associated with the basin structure may indicate the presence of a low-loss deposit that is more than 1 kilometer thick.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Picardi, Giovanni -- Plaut, Jeffrey J -- Biccari, Daniela -- Bombaci, Ornella -- Calabrese, Diego -- Cartacci, Marco -- Cicchetti, Andrea -- Clifford, Stephen M -- Edenhofer, Peter -- Farrell, William M -- Federico, Costanzo -- Frigeri, Alessandro -- Gurnett, Donald A -- Hagfors, Tor -- Heggy, Essam -- Herique, Alain -- Huff, Richard L -- Ivanov, Anton B -- Johnson, William T K -- Jordan, Rolando L -- Kirchner, Donald L -- Kofman, Wlodek -- Leuschen, Carlton J -- Nielsen, Erling -- Orosei, Roberto -- Pettinelli, Elena -- Phillips, Roger J -- Plettemeier, Dirk -- Safaeinili, Ali -- Seu, Roberto -- Stofan, Ellen R -- Vannaroni, Giuliano -- Watters, Thomas R -- Zampolini, Enrico -- New York, N.Y. -- Science. 2005 Dec 23;310(5756):1925-8.
