[WH] US Space Shuttles ran on 1MB of RAM and 80′s technology - Page 2

post #11 of 27
They used a ram tweak, upped the vcore for stability. I don't think they had a cooling issue in space.wink.gif

Actually cooling in space may very well be major problem. While outside temperature is very low, space is basically perfect vacuum and the only way to lose heat is via thermal radiation.

Actually cooling is an issue. It depends on the system and location, some things actually need a heater to prevent them from totally freezing.

It is not surprising how low tech all the shuttle systems were/are. Everything matters in space be it power, space, weight, complexity. All those system did one or two specialized tasks so they could be very very low tech.

It would be stupid to put more than absolutely required to perform a job into a computer system. Not only does that increase the chance that if something went wrong it is much harder to fix, but if it does break a complex system stands a much higher chance of affecting other systems.

In space the simpler the better.

Cooling in space can be an issue.... no air for convection or conduction. Only radiation for heat dissipation.

that was a hardware failure (structural etc) ; not a computer failure leading to shuttle disaster as said above before ^

the computers had nothign to do with the shuttle exploding

In the space technology industry it's all about 'heritage'

I'm working on a project with a satellite and other space tech company called Astrium, and the first thing they made clear to my team was that really most technology used for things like satellites and launchers is actually quite old.

If a satellite is going to be up there for say 15 years (common for a commercial comms satellite), working 24/7 throughout those 15 years, you need stuff that's been tested and proven to work that long without failure.

I imagine the computer systems in the shuttle got significant amounts of testing done initially, and then seeing as nothing went wrong with the systems (afaik), why risk replacing them with relatively untested tech? As long as it gets the job done, it's too much of a risk to change it.

No need to run crysis up there. Tried and true is the way to go.. when, you know, something very small, but wrong, can kill.

Specialized hardware doesn't need to be as robust.

If only calculating one vector or something like that, you don't need the capability to calculate 100. Conspiracy theorists use this as a fact that the moon landing is fake, but really they just don't understand technology.
