| | Mars Exploration: Features |
 | | Thirty missions to Mars have been mounted by the space agencies of the U.S., Japan, and the former Soviet Union. |
 | | Mars scientists have long desired to have their instruments in a low, circular orbit that affords beneficial lighting conditions and a uniform altitude for photography and other data taking, and Odyssey's aerobraking phase is designed to deliver that. |
