NASA's Perseverance finds organic carbon just beneath ancient Martian rock surfaces

The short version

• Perseverance has confirmed complex organic carbon just below the surface of ancient Bright Angel formation rocks on Mars.[ScienceDaily]
• The carbon sits only a few microns below the exposed surface, the shallowest such detection reported on Mars.[ScienceDaily]
• Because the material can form through chemistry without life, the finding alone cannot establish that Mars was once inhabited.[ScienceDaily]
• The Bright Angel sample was collected more than 2,000 miles from Gale Crater, where Curiosity earlier detected organic compounds.[ScienceDaily]

Key facts

• NASA's Perseverance rover confirmed complex organic carbon just beneath the surface of ancient Martian rocks in the Bright Angel formation.[ScienceDaily]
• Researchers used the SHERLOC instrument on Perseverance's robotic arm, which uses Raman spectroscopy without damaging the rock.[ScienceDaily]
• The study was co-led by Ashley Murphy and Kyle Uckert.[ScienceDaily]
• The organic carbon survived only a few microns below the exposed surface, the shallowest macromolecular carbon detection reported on Mars.[ScienceDaily]
• The Bright Angel sample was collected more than 2,000 miles from Gale Crater, where Curiosity previously detected organic compounds.[ScienceDaily]
