Hubble Telescope's payload computer is down. NASA has spent days trying to fix it.

It looks like NASA will have to boot a backup computer which was not booted since 2009. Of course it uses technnologies from the Eighties.

I hope the computer failure isn't terminal.

Nasa will attempt to fix a problem that has stopped the Hubble telescope from being used for astronomy.

It's the worst glitch in years to hit the venerated observatory.

An onboard computer halted on 13 June, leading to the science instruments being put in "safe mode" - where all non-essential systems are shut down.

It looks like a problem with power supply. A computer without electricity is useless. A recent blackout due to a thunderstorm shut down all my 4 PCs. When electricity came back, I wa able to restart three of them. Only an old laptop running Linux would not start. As a last resort, I unplugged its AC power line, since its battery was dead, then reattached it. It rebooted.

Maybe Elon Musk, if he sees a propaganda opportunity, will have his orbiter modified in some fashion to be able to make a service call on Hubble to fix the ailing computer.

The backup Power Control Unit has been successfully switched on. Operations are in progress.

NASA had to resort to Hubble alumni, that is retirees and pensioners, to fix Hubble. Its electronics was made in the Eighties.

Jeff Bezos has done it. His New Shepard rocket has crossed the Von Karman line at 100 km while Richard Branson had reached 86 km.
