Mars Reconnaissance Orbiter

Mission Summary

The Mars Reconnaissance Orbiter, or MRO, has studied the Red Planet's atmosphere and terrain from orbit since 2006 and also serves as a key data relay station for other Mars missions, including the Mars Exploration Rover Opportunity.

Equipped with a powerful camera called HiRISE that has aided in a number of discoveries, the Mars Reconnaissance Orbiter has sent back thousands of stunning images of the Martian surface that are helping scientists learn more about Mars, including the history of water flows on or near the planet's surface.
