DISCOVERS EVIDENCE OF ANCIENT FLOWING WATER
NARRATOR: Over 50 years of Mars exploration has revealed intriguing clues, suggesting Mars has a surprisingly watery past.

JOHN GROTZINGER: It’s undeniable that the early history of Mars was much wetter than it is today.

Washington, Feb 18 : NASA s Mars 2020 Perseverance rover, which is slated to touch down in Jezero Crater at around 3.55 p.m. EST on Thursday (2.25 a.m. Friday India time) is tasked with searching for telltale signs that microbial life may have lived on Mars billions of years ago.
It will collect rock core samples in metal tubes, and future missions would return these samples to Earth for deeper study, NASA said.
