Mars Rock Hints at Ancient Life, But Earth-Based Proof Is Needed
TL;DR
Analysis of Martian rock Cheyava Falls by Perseverance’s SHERLOC and WATSON detected macromolecular carbon, a potential sign of ancient organics and past habitability in Jezero Crater; but MMCs can form abiotically, so a definitive conclusion requires returning samples to Earth—an effort whose future remains uncertain amid stalled Mars Sample Return plans.
