Ice Cap to Ice Cap with Mars Odyssey The Planetary Society

On March 23, 2013 the Mars 2001 Odyssey spacecraft completed 50,000 orbits around the Red Planet. If it’s not a mixed metaphor to call a solar-powered robotic orbiter a workhorse, then Mars Odyssey is a serious contender for the title of Workhorse of the Solar System. In December 2010 Odyssey broke the previous record to become the longest-working spacecraft at Mars.
In addition to mapping the planet, Odyssey also serves as a crucial communication link, relaying signals between Earth and several rovers as they land and drive on the Martian surface.
Since the spacecraft entered orbit in October of 2001, the teams managing Odyssey’s thermal emission imaging system have captured nearly 670,000 images in visible and infrared light.
