NASA - National Aeronautics and Space AdministrationPasadena, CA – The NASA Mars Odyssey orbiter has resumed duty after switching to a set of redundant equipment, including a main computer, that had not be used since before the spacecraft’s 2001 launch.

Odyssey relayed data to Earth late Sunday that it received from NASA’s Opportunity rover on Mars using the orbiter’s fresh “B-side” radio for UHF (ultra-high frequency) communications. In plans for this week are relay opportunities for the newest Mars rover, Curiosity, and resumption of Odyssey’s own scientific observations.
