NASA may have discovered a biosignature on Mars, but could China be in position to get crucial samples back to Earth first to make a definitive analysis?
NASA's Perseverance team announced on Sept. 10 that it had found possible biosignatures in pieces of a Mars rock dubbed "Cheyava Falls" in Jezero Crater. But this is not conclusive. In order to determine if the intriguing minerals were produced by microbial metabolism or an abiotic process, samples collected by the rover would need to be delivered to Earth for further analysis, team members have stressed.
