Sample Analysis at Mars (SAM)

New Capabilities

Produced the organic-molecule detections

For 14 years, the Curiosity rover has looked for organic molecules on Mars by heating samples in a tiny onboard oven. The method works, but it destroys fragile compounds before they can be identified. On April 22, 2026, NASA reported that a different technique—squirting a chemical solvent onto a Martian rock sample before heating it—revealed more than 20 organic molecules the rover had never seen before.
