Mission Status Report

PASADENA, Calif. -- NASA's Mars Odyssey orbiter has resumed its science
observations and its role as a Mars rover's relay, thanks to a spare
part that had been waiting 11 years to be put to use.

One of the most amazing photos I've ever seen is from Odyssey. It shows
the purchute of one of the rover missions as it decended through the
Martian atmosphere. The first photograph of a spacecraft at another
planet taken by a spacecraft at another planet.
