Mars: October 2020


The agency's newest rover will use the first ground-penetrating radar instrument on the Martian surface to help search for signs of past microbial life.

Data from Martian meteorites suggest the planet may have two hydrogen reservoirs beneath its surface, according to a recent study by NASA's Astromaterials Exploration Research and Science (ARES) Division and a team of planetary scientists. The study, published in the journal Nature Geoscience, could shed light on how Mars formed and evolved.

The detection of liquid water by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) at the base of the south polar layered deposits in Ultimi Scopuli has reinvigorated the debate about the origin and stability of liquid water under present-day Martian conditions.
