NASA is working to resolve an issue with the payload computer on the Hubble Space Telescope. The computer halted on Sunday, June 13, shortly after 4 p.m. EDT. After analyzing the data, the Hubble operations team is investigating whether a degrading memory module led to the computer halt.

The computers on Hubble would have been built in the late 80s. I wonder how many people are still around who understand how they work?
One of those critical infrastructure programs slo-jo told Vlad was off limits???
Computer got a blue screen of death. It must still be running windows 95.
windoz... installing updates...
Degrading Memory Module:
BIDEN STRIKES AGAIN !!!!!
Probably MS10’s One Drive asking to link all its devices. For its own good. Or else.
Pesky null pointers.
Reset? You don’t want to do that, Dave.
This will only take 3 hrs. Restarting now.
One of the new security problems is that you can’t stop windows from downloading updates to fix the old security problems or the patches to fix the bugs in the poorly tested last version or the really really HUUUGE update because the whole thing is in such a mess we need to start over from scratch with a whole new set of patches on patches on patches.
indeed
I wonder just how much of the electronics got swapped out in the last upgrade ~11 years ago. I'd hope a lot, and not with the latest and greatest chips (small geometry structures are more susceptible to damage), but chips that are robust.
This time, they’ll be no Shuttle to take astronauts up there to replace the module.
SciTechDaily:
"The payload computer is a NASA Standard Spacecraft Computer-1 (NSSC-1) system built in the 1980s. It is part of the Science Instrument Command and Data Handling module, which was replaced during the last astronaut servicing mission in 2009. The module has various levels of redundancy which can be switched on to serve as the primary system when necessary."

or it’s trying to upgrade to Windows ME ,LOL
Give Elon a year and he’ll take care of it for NASA. Just like he’s taking astronauts and supplies up the ISS when NASA still can’t get theirs off the ground.
I’ve been in the solar business since the 1980s
I’ve said for years that solar panels will last forever at least 100 years
Voyager launched in 1970 is out of our solar system
It is still sending back pictures to NASA. 50 years later
This is only possible because of two things : solar panels and batteries( and electronics ) that were developed at the time !! which can still be producing power now without ever having been touched or replaced
Same thing is true with Hubbell although Hubbell has the advantage of being Launch to 20 years later
Still it was only the solar / battery technology that was available in 1990
A little background on different solar technologies
Homeowners and business owners get modules that are made of Crystal and silicon Delta LuminaSkin boron for the n- and p- layers
Crystalline silicon photovoltaic cells have a theoretical efficiency maximum of 28% and the most efficient solar panels are around 20% efficient
NASA uses gallium arsenide cells with a theoretical efficiency of 40%
Gallium arsenide technology is much more expensive and that’s why it’s only used by NASA word cost $1 million a pound to send anything into space
Voyager doesn’t have any solar panels. They wouldn’t do much good out where it is, anyway. Voyager runs on a plutonium-238 RTG.
