CAPE CANAVERAL, Fla. — Three years after landing in a giant Martian crater, NASA's Curiosity rover has found what scientists call proof that the basin had repeatedly filled with water, bolstering ...

The discovery suggests that parts of Mars may once have supported tropical-like climates, complete with heavy, sustained rainfall.

NASA’s Perseverance rover has uncovered signs of an ancient Martian shoreline, hinting at long-lasting lakes, subsurface water activity, and conditions that may once have supported life on the Red ...

A mudstone sample from Jezero Crater shows textures and minerals that on Earth often form through microbial activity. Scientists caution that nonbiological processes could also explain the features, ...

Long before Mars turned into the frozen desert you see today, water shaped its surface in dramatic ways. Rivers cut through highlands, lakes pooled inside craters, and floods tore open canyon walls.
