Mars rock hints at ancient life.

Mars rock with organic carbon may hint at ancient microbial life.

Why it matters

  • Rock contains organic carbon and minerals linked to Earth’s microbial life.
  • Suggests Mars may have hosted microbial life.

By the numbers

  • Located in Jezero Crater, an ancient lake system.
  • Contains vivianite and greigite, minerals tied to microbial activity on Earth.

The big picture

  • Discovery sets stage for further Martian sample analysis.
  • Potential step in understanding Mars' past habitability.

What they're saying

  • Scientists excited but cautious; more evidence needed.
  • Budget cuts threaten future missions and research.

Caveats

  • Not conclusive proof; abiotic processes could explain findings.
  • Sample needs Earth-based analysis.
  • Mars Sample Return mission faces budget issues.

What’s next

  • Perseverance collected a sample, named Sapphire Canyon.
  • Future missions aim to return samples to Earth.
