Mars Odyssey is a orbiter mission by NASA / JPL targeting Mars. Launched April 7, 2001. Currently 1.4145 AU from the Sun.

Mars Odyssey is the longest-serving spacecraft in orbit around Mars, operating since 2001. It mapped the distribution of chemical elements and minerals on the Martian surface and found evidence of vast subsurface water ice deposits. It continues to serve as a crucial communications relay for Mars surface missions.

  • Mapped hydrogen distribution indicating subsurface water ice
  • Found vast ice deposits near Martian south pole
  • Longest-serving spacecraft in Mars orbit
  • Key relay satellite for Mars surface missions
