The US Air Force used to run farms of PS3s running Linux. There was also the folding@home project for the PS3!So we have PS1's dominating space and PS2's dominating the military. I wonder what they will do next with the 3 and 4?

Nice, maybe they'll use the cell processor next to power an.unmanned reconnaissance vehicle to land on other worlds.
Why did it stopped working in the first place?
They were going to run it at full speed, but couldn't find an extension cord for the power outlet that was long enough.
As for 486, I've seen 486-based PCs crash a whole heck of a lot more than I've seen a PSX crash. The PSX CPU is quite a bit simpler and less power hungry, which is important for a long mission away from human hands like this.
Hey, the Wii also in space:

"Dual BAE RAD750 @ 400MIPS (up to 200MHz): Radiation Hardened version of the IBM PowerPC 750 (one configured as a backup, that can take over if the other fails (or a software update disables it). The processor is designed to have no more then one single event upset (a problem requiring intervention from Earth) in its 15 year lifespan."
Stability doesn't seem to be the issue here. Stuff in LEO (low earth orbit) often uses x86 CPUs. Hubble uses a 486 CPU, the ISS a 386 CPU. I assume those chips require either too much power, or too much shielding (or both) to be useful for deep space stuff.They were going to run it at full speed, but couldn't find an extension cord for the power outlet that was long enough.

According to the website above the Sony Playstation CPU that's now in New Horizons has been modified for space travel and now costs $20,000 to $40,000

See Sony, I told you now was the time for a new Colony Wars on PS4, even NASA helps you out for the marketing!!!1
If the original PSX can fly to Pluto and play Colony Wars just imagine what the PS4 could achieve in Space with a new Colony Wars!
Yeah a Pentium would work better imo. My Pentium 4 is still going strong from over a decade of use.
This is kinda silly

I think they should have used Pentium.
*gets called out*
I didn't know I needed to actually know what I was talking about to have an opinion fuck you guys.

486 crashes are probably more to do with the software, and/or the associated system (ram, NB/SB/etc..)
The question of 486 vs MIPS3000, it probably came down to power consumption as you ay, but also performance. the MIPS3000 does about 5x's the performance of a 486 DX 66mhz in floating point. I would assume FP is the types of calculations needed for navigational calculations.
Downclocking would also be about reliability and power consumption.
PPC 750 is based on AIM's PPC G3 Apple CPU..so Apple G3 is in space~ I had a G3 and it was a monster....

There's no up nor down in space (or maybe there is).... which means that PS1 will perpetually work, and cats will keep on turning!
Wonder why they didn't just use a 486 or the original Pentium or something...
The reason for all this redundancy, and for the relatively anemic hardware in the first place, is power consumption and radiation hardening.
Can anyone explain why they use this instead of a newer part? It says that they use older parts for reliability, but wouldn't it be possible to make a newer part that's more reliable, more powerful, and more power efficient? Or does it become a matter of cost at that point?

Because when you thought your PS1 was broke, you can turn it upside down and it will work.
Some of the NASA people probably grew up and knew about the durability of the PS1 with that simple trick, so they decided to use the PS1 CPU.

Fun fact, voyager was a modified nes and the reason its been able to operate so long is the cartridge slot was left open, allowing for space dust to continually blow into the compartment to ensure normal operation.
Never stop fighting the good fight Sidewinder. I'm with you brother.
Yeah I think NASA scientists are more qualified to make that judgement.
The RAD750 is a 10W board. The Mongoose-V is a really lower power board in comparison. When you're away from the sun relying on an ever lowering output RTG every watt counts.
The R3000 instruction set is tiny. 50 instructions in total IIRC and has a very limited number of addressing modes. A tiny number of instructions compared to the 486 which has hundreds plus four addressing modes. More instructions, larger decodes, more powerful decoder, more microcode, larger chip, more power, more bugs.
R3000 programs are easier to code, easier to debug, easy to step through, easy to know what will happen. You don't exactly get multiple shots at this stuff so its kind of imperative you're able to know with some measure of certainty that what you put there is what's going to happen.
The other thing is that VxWorks doesn't support the 486. This RTOS is legendary for being absolutely fucking bulletproof and it's NASA's go to off the shelf OS for that very reason. It doesn't support any earlier than a Pentium. But its been on MIPS for decades.
Gotta keep us occupied somehow or we'll have to start playing games.GAF has expanded its range into armchair embedded systems engineering, well done
