The Perseverance rover discovers a "treasure" of biological materials on Mars.

According to NASA scientists, the Perseverance rover has gathered some of

the most crucial samples thus far on its mission to ascertain whether life has

ever existed on Mars while exploring the location of an old river delta.

Organic material has been found in a few of the most recent samples, proving

that Jezero Crater, which most likely formerly housed a lake and the delta that

flowed into it, may have once supported possibly livable habitats 3.5 billion

years ago. According to Ken Farley, project scientist for the Perseverance

mission at the California Institute of Technology in Pasadena
