This is a concept video by NASA’s Goddard Space Flight Center in Maryland of how the Martian atmosphere and landscape may have changed in the past 4 billion years. MAVEN’s mission is to find out whether the theories of change are correct. MAVEN will orbit Mars with a suite of instruments that will scan the upper atmosphere for proof of the existence of a much richer ancient atmosphere above the Red Planet. You can also find out more details about what informed the concept art and production here.
