NASA's Perseverance rover found a rock on Mars that could indicate ancient life

But the rock still has to be sent back to Earth for extensive testing.

NASA's Perseverance rover has been collecting samples from Mars since 2021, but one of its most recently collected rocks could help it achieve its goal of finding evidence of ancient life on the planet. Nicknamed Cheyava Falls after the tallest waterfall in the Grand Canyon, the 3.2 feet by 2 feet sample contains "chemical signatures and structures" that could've been formed by ancient microbial life from billions of years ago.

Perseverance collected the rock on July 21 from what was once a Martian river valley carved by flowing water long ago. The sample, which you can see in close up below and from afar at the center of the image above, exhibits large white calcium sulfate veins running along its length. They indicate that water did run through the rock at one point.
