What kind of computers are in use at Mission Control Center?

Hi,

Here in Sweden we have seen a lot of clips from Mission Control Center,
Mission Launch Center and from Flight Control. I wonder what kind of
computers are in use and what operating system they are using? I have
seen tracking with familiar Linux and windows IDE. Mission critical
software runs on Unix, maybe?

Mainly DEC Alpha workstations running Unix for the critical tasks, PCs
running Windows (on a separate network) for the non-critical tasks.

The DECs are quite obsolete (two mergers ago...) and NASA is looking at
replacing them with PCs running Linux.

So mainly DEC's True64 Unix, no VMS? All that stuff looks like kind of
new on TV with nice graphics, I mean mainly clips with computers behind
Mike Leinbach.

What about the mainframe (I think called the MOC)? Is it still in
operation?

Right, no VMS. Though I don't remember it being "True64" Unix.

Nope, it's finally been decommissioned, replaced by a new Trajectory
Server.

No, of course not. It's 'tru64 unix', derivate from OSF/1 I think. My
mistake, sorry...

Does it emulate the MOC (e.g. use GDR and run the MOC code), or did they
bite the bullet and rewrite a BUNCH of code?
