Между тем, из NASA неофициально сообщают, если верить SpaceRef, что причиной потери Mars Global Surveyor стала ошибка в обновлении программного обеспечения, присланного с Земли:

According to public comments made by McNamee: “We think that the failure was due to a software load we sent up in June of last year. This software tried to synch up two flight processors. Two addresses were incorrect – two memory addresses were over written. As the geometry evolved, we drove the [solar] arrays against a hard stop and the spacecraft went into safe mode. The radiator for the battery pointed at the sun, the temperature went up, and battery failed. But this should be treated as preliminary.”

Global Surveyor вращался на марсианской орбите с 1997-го года и принёс множество интересных и важных данных. Аппарат потеряли в октябре 2006-го.
