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.
Given the samples of Mars that Perseverance has collected so far, could one of those specimens be what the rover was sent to look for in the first place: evidence of past microbial life on the Red Planet?
