The Astrobiology Field Laboratory (AFL) (also Mars Astrobiology Field Laboratory or MAFL) was a proposed NASArover that would have conducted a search for life on Mars.[1][2] This proposed mission, which was not funded, would have landed a rover on Mars in 2016 and explore a site for habitat. Examples of such sites are an active or extinct hydrothermal deposit, a dry lake or a specific polar site.[3]
Had it been funded, the rover was to be built by NASA's Jet Propulsion Laboratory, based upon the Mars Science Laboratory rover design, it would have carried astrobiology-oriented instruments, and ideally, a core drill. The original plans called for a launch in 2016,[4] however, budgetary constraints caused funding cuts.[5][6]
