HERE’S THE BACKGROUND — Anywhere there’s water on Earth, some form of life has managed to survive. Scientists believe that Mars once had flowing rivers, lakes and maybe even an ocean.
Tanya Harrison, a planetary scientist and director of science strategy for Planet Labs who was not involved in the study, says that knowing that Mars had water in the past is important for understanding if life ever arose on Mars.
