Default 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 ??

  • NASA is a large organization spread across several sites with groups with wildly different needs. No single platform is used across the entire organization, nor should there be.
  • NASA also has to support hardware/software combinations which were adopted decades ago. Due to the rigid requirements made on testing & the length of time need to complete thorough testing, new software just isn't an option.
  • Because of some of the demands made (low power, meagre hardware complements requiring minimal software, etc.) on the solutions developed, VwWorks was commonly used back in the '90's & early 2000's, & is still in use today.
The shuttle program (circa 1980's - 2000's) was designed in the 1970's. Much of the software used had to be bulletproof at the time of implementation. This is why Fortran was commonly the implementation choice.

You must have missed the link I provided above, daemonfowl It is full of documents, images, news releases, and podcasts. From NASA. On the subject of computers in space.

I believe that the ISS has recently made the switch to some type of Linux.

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:

SUSE?! Now that's suprising...

Historically:

OS/360 was a real McCoy...


So, what about the future?

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.

Default 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).
