What the rover confirmed
Perseverance, the NASA vehicle that travels across the Martian surface, has verified the presence of complex organic carbon lying just under the surface of ancient rock. Organic carbon is one of the chemical ingredients associated with life, although its presence on its own does not show that life existed.
Preservation and wider distribution
The compounds are described as remarkably well preserved. A report on the discovery also points to similar findings at sites thousands of miles away, which it says could indicate that the building blocks of life were once spread widely across the planet.
Open questions
- Does the preserved organic carbon point to biological activity or to non-biological processes?
- How many of the similar discoveries thousands of miles away have been independently confirmed?
