SHARAD Illuminates Deeper Martian Subsurface Structures with a Boost from Very Large Rolls of the MRO Spacecraft
Throughout its mission, the Mars Reconnaissance Orbiter (MRO) has often rolled about its along-track axis by up to 28° to partially compensate for the suboptimal location of the Shallow Radar […]

Spectral Evidence For Irradiated Halite On Mars
The proposed chloride salt-bearing deposits on Mars have an enigmatic composition due to the absence of distinct spectral absorptions for the unique mineral at all wavelengths investigated.

Orbital View Of Chloride Salt Deposits In Terra Sirenum On Mars
A purplish, scaley wave lures the attention of a European spacecraft as it flies over Mars’s Terra Sirenum, Latin for Sea of the Sirens. It is just an optical illusion […]
