Possible sign of Mars life? Curiosity rover finds ‘tantalizing’ Red Planet organics

NASA’s Curiosity rover has found some interesting organic compounds on the Red Planet that could be signs of ancient Mars life, but it will take a lot more work to test that hypothesis.

Some of the powdered rock samples that Curiosity has collected over the years contain organics rich in a type of carbon that here on Earth is associated with life, researchers report in a new study.
