Campbell, Bruce A.; Morgan, Gareth A.; Bernardini, Fabrizio; Putzig, Nathaniel E.; Nunes, Daniel C.; Plaut, Jeffrey J. (2021)The Shallow Radar (SHARAD) instrument on the Mars Reconnaissance Orbiter (MRO) has been operating since 2006, revealing the detailed layered structure of the polar caps, mid-latitude glacial deposits, and a range of volcanic ...

Campbell, Bruce A.; Campbell, Donald B.; Morgan, Gareth A.; Carter, Lynn M.; Nolan, Michael C.; Chandler, John F. (2015)We combine Earth-based radar maps of Venus from the 1988 and 2012 inferior conjunctions, which had similar viewing geometries. Processing of both datasets with better image focusing and co-registration techniques, and ...

Putzig, Nathaniel E.; Morgan, Gareth A.; Campbell, Bruce A.; Grima, Cyril; Smith, Isaac B.; Phillips, Roger J.; Golombek, Matthew P. (2016)We carried out an assessment of surface and subsurface properties based on radar observations of the region in western Elysium Planitia selected as the landing site for the InSight mission. Using observations from Arecibo ...
