Planetary Science and Exploration

Mars has become the central laboratory for understanding how rocky planets evolve, lose water, and either sustain or extinguish the conditions necessary for life. Decades of orbiters, landers, and rovers have mapped ancient riverbeds, identified clay minerals that form only in liquid water, and measured an atmosphere thin enough to strip away most surface moisture — yet the planet's early history remains contested. Researchers are now working to determine whether subsurface liquid reservoirs persist today and whether microbial life could survive in the briny, radiation-battered environments that remain. The answers bear directly on both the origins of life as a planetary phenomenon and the practicalities of eventual human presence on Mars.
