Sometimes redundancies also add opportunities. We would have far fewer pictures from Voyager 2’s pass by Uranus, in 1986, and Neptune, in 1989, without a duplicate set of computers standing by, coupled with mission control’s ability to upload new software to take advantage of them. The inertial measurement units of the Mars Odyssey, launched in 2001, and the Mars Reconnaissance Orbiter, launched in 2005—which allow the two satellites to determine their absolute position in the universe while also noting changes in rotation, orbital speed, and other parameters—are nearing the end of their utility in the coming months (or years). Currently, they help the orbiters remain in the right spot and elevation above Mars, and keep their antennae pointed back at Earth. When these sensors fail, it would mean an end to the orbiters’ ability to collect and transmit data back to Earth—were it not for flexibility built into the software. Scientists are testing new software that will eventually allow both satellites to analyze their position from a star-tracking camera on board each craft, affording them additional years of usable life.
