NASA Rover Finds Igneous Rocks Indicating Complex Water Interactions on Mars

Summary

NASA’s Perseverance rover has found igneous rocks on the edge of Jezero Crater that preserve evidence of at least three separate water interactions on ancient Mars. Scientists say the discovery could help reconstruct the planet’s climate and past habitability.

Key Points
  • Perseverance unexpectedly found igneous rock at the Margin Unit on the edge of Jezero Crater instead of the sedimentary rock scientists had anticipated.
  • The rocks preserve evidence of interactions with carbon dioxide-rich groundwater, ancient lake water, and later hot groundwater.
  • The SuperCam instrument analyzed more than 185 rocks using reflected light and laser technology.
  • Researchers say the finding could help explain the climate and life-friendly environment of ancient Mars.
