Earthly Software Rebooted Mars Spirit Rover

Posted by TimSlavin at February 18, 2004

"It's a PC user's nightmare: You're almost done with a lengthy e-mail, or about to finish a report at the office, and the computer crashes for no apparent reason. It tries to restart but never quite finishes booting. Then it crashes again. And again.

Getting caught in such a loop is frustrating enough on Earth. But imagine what it's like when the computer is more than 100 million miles away on Mars. That's what mission controllers faced when the Mars rover Spirit stopped communicating last month." Neat little case study, in effect, that any programmer will recognize. From Wired News.
