NASA's Perseverance rover discovered rocks on Mars, providing new evidence the red planet was once a wet, habitable world ...

“If life ever appeared on Mars billions of years ago… chemical traces of this ancient life could still be present today for us to detect,” analytical chemist Caroline Freissinet of the French National ...

"You need so much water that we think these could be evidence of an ancient warmer and wetter climate where there was rain falling for millions of years." ...

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

NASA’s rover Perseverance spent nearly a year exploring the rim of a crater believed to have held a huge lake.

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 ...

When the Perseverance rover landed in Mars’s Jezero crater—a formation that long ago was Jezero lake—in February, 2021 it turned west. West is where the riverbeds, the deltas, the sites of ancient ...

The Perseverance rover is continuing its mission to find clues about the geological past of Mars. The rover’s main goals are ...

Bright white rocks found by NASA’s Perseverance rover hint at ancient Martian rain lasting millions of years, raising new questions about how wet Mars once was and what those conditions might mean.

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.

“The presence of liquid water [on Mars] is a broad topic that includes rains, rivers, lakes, as well as oceans,” says Ezat ...
