ABOUT MARS ODYSSEY
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.
KEY DISCOVERIES
- Mapped hydrogen distribution indicating subsurface water ice
- Found vast ice deposits near Martian south pole
