Mars rover finds ancient rock with potential biosignature

The Washington Post — July 26, 2024, 03:00 AM UTC

Summary: NASA's Perseverance rover has discovered a rock named "Cheyava Falls" in Jezero Crater, containing organic molecules and markings potentially indicative of past biological activity. Sampled on July 21, the rock measures 3.2 by 2 feet and is part of the Mars Sample Return mission, which faces budget concerns, with costs estimated between $8.4 billion and $10.9 billion, delaying sample return to Earth until 2040.
