Idk about the payload computer, but I've got to think guidance and operation controls would have at least some remnants of legacy keyhole technology, or would expose hardware details that might still be sensitive information, even if the software was a total rewrite.
- _joel 5y agoHubble is basically a US spy satellite, pointing outwards instead of inwards. I'm sure there will be similar classes of hardware still in operation, so could be some sensitivity there.
- beerandt 5y agoYeah- that's what keyhole is: a codename for a series of nro/ nga spy sats. Edit: and Hubble was built from a surplus skeleton of one, through a government transfer. https://en.m.wikipedia.org/wiki/Key_Hole https://en.m.wikipedia.org/wiki/Key_Hole
- setug 5y agoIt's a 30/40-yr old code and hardware. Now that I think about it, the problem could be related to some "exotic" decisions made by that time...
- beerandt 5y agoLots of 30/40 year old hardware is still classified, especially spy technology.
- setug 5y agoThen hiding it when it's on Earth could make sense, actually attacking Hubble is much more complicated that anything on earth, given that you can actually put your hands on it, connecting through a JTAG and understanding what's wrong (besides spying).
