The microbial study reads: “Data accumulated over the past few decades by orbital and landed missions have demonstrated that early in its history the planet may have been habitable for microbial life with abundant sources of energy, carbon, nutrients, and shelter.
“Mars supported both surface and subsurface water and may still do in some circumstances, as well as organic molecules required for life.
“As a result, Mars 2020 and ExoMars missions will be searching for biosignatures, and the investigation of terrestrial analogues can provide critical insights for the development and testing of exploration strategies.”
The incredible study was completed with funding from NASA’s Astrobiology Science and Technology for Exploring Planets (ASTEP) Program Grant.
