Perseverance rover’s Mars rock sample may contain best evidence of possible ancient life

The lead scientist for NASA’s Perseverance Mars rover is excited about material that has been stored in the rover’s sample tubes, both dropped on the surface of Mars and contained within the rover itself while wheeling about within Jezero Crater. 

In reviewing the samples of Mars that Perseverance has collected, scientists say one tube appears to be packed with what the rover was looking for: evidence of past microbial life on the Red Planet.
