I'm Curious,

Does NASA use Linux on there computers? If so what distro?

I saw something on the science channel that looked like Linux

there is probably a combination depending on what part of NASA it is being used in

It will be seriously optimised for the space station, since they still use 486 processors!

Well, I doubt they'd be using Kubuntu now would they...

I was thinking more like what they use at JPL.

@Andy

They still use i486 processors? wow.

They would use Linux, but I've read they rely heavily on their own programming languages.

I know they use XP and 2K on the machines on ISS, their guidance systems are custom made and I recall seeing something about a megacluster of linux boxen doing numbercrunching and simulations.

On the Space Shuttles, they are using 8086s... a special kind of them (a version that is more resistant to radiation). They had/have to buy used ones now, because they aren't manufactured anymore. ^^ I'm wondering .... Which OS do they use on these machines...

Actually they use an IBM AP101 which afaik is a System/360 derivative. They have 5 of them to ensure redundancy, all running the same custom guidance software in parallel and crosschecking every step of the way. It's kinda hard to say which OS runs on them because as far as I can see there is none. The computers are designed to run one "app" and that's it.

I don't know about NASA, but the NSA uses a custom, secure version of Linux. They actually released a distro called SELinux that is based on it, iirc.

I'd guess maybe NASA is using a distro based on that as well.

The idea is sound I suppose, but NASA and NSA have only three letters of the name in common really. NSA deals with national security whereas NASA deals with the continued exploration of earth and space. Their application and uses of various OS:es have very little in common aside from the pure number-crunching concept. NASA is also such a huge entity that it'd be impossible to run only one system across the board. For things requiring massive computers in the order of 128+ CPUs they use Linux but for a lot of the other things like mission control and as end-user systems on crafts they use Windows.

Pretty much everything NASA uses is developed in-house or custom made. Hardware, software and crafts are things developed at NASA or some research branch of the government which then later finds it's way down to the "common people". :)

Things I've heard and read suggest in-house customized Red Hat and/or SUSE distros. I've also heard Hard Hat Linux (now MontaVista Linux) and SL (Scientific Linux) mentioned too.

Didn't Donald Becker come from NASA? One of the big linux kernel guys is.. I remember he is the one that got the networking going...

NASA (much like any other civilian .gov agency) pretty much uses what is avail at that moment.

Hell they even ran A/UX at one point.

It's always whatever tool fits the bill for next to nothing at that moment...

One should note in passing that the Russians made their own version of DOS (PTS-DOS), for use in their own installations (eg satalites). It must be recalled that doing this prevents external influences on the code base.
