Mars exploration motivates the search for extraterrestrial life, the development of space technologies, and the design of human missions and habitations.  ...  In addition, Mars exploration can drive future policy developments and confirm (or put into question) the feasibility and/or extent of human habitability of space.  ...  The upper concentration limit was estimated at 20 ppb (Mège and Masson, 1996) . In 2003, methane detection changed dramatically.  ...
