OS'es in outer space
I've read that NASA made an auction for 286 CPU's not a long time ago...
As it turns out, last time - when they made an upgrade - they rocket gone boom-boom, 'cause fuel-flow-controlling-app, which worked around very hardware-limited int range became lost in a land of long, modern int's... And it pumped fuel... And it pumped fuel... And even more fuel... And now I'm wondering: What are they using in space? NetBSD? Of course it runs NetBSD, but I'm not so sure about it... There are great videos from ISS on the net, and one can see a lot of unfamiliar, swastika-like, red-green-blue-and-yellow signs on their thinkpads... //But these are just personal desktops ;-) What runs on the CRITICAL computers? |

Nasa was quoted by some as being using Fedora (on land)
NetBSD has the historical fame for running Sam II .. and is most portable and most scalable while still being Energy-saving .. OpenBSD is most secure and I recall Sir Theo de Raadt was asked by some NASA guy(s) how to implement Puffy If not the BSDs .. then what ?? one-eyed lover ? ok ok .. I mean on Mother Gaia .. not on space particularly .. but again wouldn't this economical crisis hinder space-oriented activity from thriving these coming years ?? |

Thanks...
Hmmm... Now that is one die-hard fu... http://www.computer-museum.ru/english/argon16.htm Completion of development: 1973. Beginning of production: 1974. Termination of production: still in production. During 25 years of operation no failures of the system were noted when working in control systems. -- Earth-ISS transportation goes down by Soyuzes, right ? ;-) Hmm... I dont know if we can talk about "operating system" with this kind of hardware... More like Operator Program, I guess... For interested: http://web.mit.edu/slava/space/computers.htm -- Back to NASA: http://www.nas.nasa.gov/hecc/resources/endeavour.html SUSE?! Now that's suprising... Historically: http://history.nasa.gov/computers/contents.html http://www.youtube.com/watch?v=nrwpXEiTDVk OS/360 was a real McCoy... So, what about the future? http://singularityhub.com/2013/06/05...e-lab-at-nasa/ " Just what do you think you're doing, Dave? " |

NASA had used SPARC/Ultra(64)SPARC equipment at the Wallop's Island facility. Wallops is the satellite for the Goddard facility. Depending on the project, I am aware that there are some (Ultra)SPARC chips used on small satellites.

rtos
I imagine that, excepting for laptops - space-borne systems are mostly the domain of microcontrollers of this sort or that, and various manifestations of RTOS operating systems. I'm pretty sure that FreeBSD ports has the RTEMS RTOS, which I believe had various space applications (like ballistic missile control).
