After a year of scientific scrutiny, a rock sample collected by the Perseverance rover has been confirmed to contain a potential biosignature. The sample is the best candidate so far to provide evidence of ancient microbial life on Mars. go.nasa.gov/4n35lVM
ALT A self-portrait photo of the Perseverance rover on the surface of Mars, taken with a camera on its robotic arm. The six-wheel rover sits in a rocky desert landscape. Its robotic "head" is pointed down to one rock where there is a small hole drilled, along with a small pile of light-colored tailings from the drill.
ALT A close-up photo of layered rocks. Between two layers, in reddish mudstone, are small, dark spots, slightly lighter at the middle of each spot.
