"Similarly, the Russian Soyuz capsule’s computer ran on only 6 kilobytes of RAM until it was replaced with newer systems in 2003, which most probably was the cause of its subsequent crash-landing in Kazakhstan."
Really? Really?
- ugh 17y agoReally (http://en.wikipedia.org/wiki/Soyuz_TMA-1 http://en.wikipedia.org/wiki/Soyuz_TMA-1). That was the first flight of the new Soyuz TMA with a glass cockpit. The capsule’s failsafe mechanisms where triggered and the it fell back to the harsher ballistic reentry instead of the normal controlled one (nobody was harmed). It seems that a system which has been in use since 1979 somehow got confused by the sensory data. Some sort of odd bug, they have never been able to reproduce it. Fallback to ballistic reentries also happened later with TMA-10 and TMA-11 – in those two cases a damaged cable and a pyro bolt malfunction (which nearly got the crew killed) were responsible respectively.
