Fatal Error: Buggy Software May Have Crashed Mars Polar Lander
The software problem that likely crashed the Mars Polar Lander into the Red Planet's frozen ground is striking mainly for its obviousness, according to a software safety expert at the Massachusetts Institute of Technology (MIT).
The problems that NASA-sponsored investigation panels blame for the lander's failure, "are well known as difficult parts of the software-engineering process," wrote Nancy Leveson in an e-mail correspondence with SPACE.com. Leveson is a professor of aeronautics and astronautics at MIT. She specializes in making critical software systems safe and robust.
"With software it's much harder to see what they've got. So they can't see that they've made this mess. There was no Testing Done"
