The twin Viking landers of 1976 were NASA’s first life detection mission, and although the results from the experiments failed to detect life in the Martian regolith, and resulted in a long period with fewer Mars missions, it was not the end of the fascination that the Astrobiology science community had for the red planet.The field of Astrobiology saw a resurgence due to the controversy surrounding the possible fossil life in the ALH84001 meteorite, and from the outsized public response to this announcement, and subsequent interest from Congress and the White House, NASA’s Astrobiology Program (,Also at this time, NASA’s Mars Exploration Program began to investigate Mars with an increasing focus on missions to the Red Planet.
