Summary

Story summary

NASA’s Perseverance rover detected complex macromolecular carbon at the Bright Angel site in Jezero crater.
JPL scientist Kyle Uckert said it is the shallowest organic detection on Mars.
Planetary Science Institute’s Ashley Murphy cautioned that the carbon does not prove past life.
The rover logged hits on two mudstones and found carbon on the bare surface beneath only a dust film, requiring no drilling.

History

Historical Context

In 1976 NASA’s Viking 1 and Viking 2 landers performed the first systematic search for Martian organics, with the GCMS detecting carbon at only a few parts-per-billion. The 2008 Phoenix discovery of perchlorate showed heating could destroy organics, prompting re-analyses that suggested hidden compounds. Perseverance’s 2021 detection of macromolecular carbon at Jezero therefore builds on Viking’s pioneering but ambiguous results.
