Der Nasa-Rover Perseverance hat potenzielle Biosignaturen auf dem Mars entdeckt, die auf einstige mikrobielle Aktivitäten hinweisen.

Unusual mudstones found on the Red Planet are potentially associated with ancient Martian microbes.

Collected last summer, the sample is from reddish, clay-rich mudstones in Neretva Vallis, a river channel that once carried water into Jezero Crater.
