TL;DR: 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 and a planar reflector associated with the basin structure may indicate the presence of a low-loss deposit that is more than 1 kilometer thick.

TL;DR: The VIRTIS instrument on board the Rosetta spacecraft has provided evidence of carbon-bearing compounds on the nucleus of the comet 67P/Churyumov-Gerasimenko, and no ice-rich patches are observed, indicating a generally dehydrated nature for the surface currently illuminated by the Sun.

TL;DR: The ice-rich south polar layered deposits of Mars were probed with the Mars Advanced Radar for Subsurface and Ionospheric Sounding on the Mars Express orbiter, suggesting a composition of nearly pure water ice.

TL;DR: Radar data from Mars Express show that there is a lake of liquid water underneath the solid ice of Mars’ southern ice cap, and this feature has high relative dielectric permittivity, matching that of water-bearing materials, which is interpreted as a stable body of liquidWater on Mars.

TL;DR: In this paper, an anomalously bright subsurface reflections were found within a well-defined, 20km wide zone centered at 193°E, 81°S, surrounded by much less reflective areas.
