Hubble Space Telescope sidelined by issue with its 1980s computer

Hubble Space Telescope sidelined by issue with its 1980s computer
"The Hubble operations team is working to solve the payload computer issue onboard the Hubble Space Telescope. The team is working to collect all the data available to them to isolate the problem and determine the best path forward for bringing the computer back to operations. At this time, there is no definitive timeline for bringing the computer back online. However, the team has multiple options available to them and are working to find the best solution to return the telescope to science operations as soon as possible. Launched in 1990, Hubble has contributed greatly to our understanding of the universe over the past 30 years."
Just send up a shuttle, ..., oh, yeah, no, can't do that.

yer... how can you operate in space without a space vehicle :)

Voyager did OK OK with faulty memory and a radio receiver failure that cut the receiver bandwidth to very little.

Don't give up on Hubble yet.

https://en.wikipedia.org/wiki/NSSC-1
The NSSC-1 had an assembler/loader/simulator toolset hosted on Xerox XDS 930 (24- bit) mainframe. An associated simulator ran at 1/1000 of real time. The Xerox computer was interfaced to a breadboard OBP in a rack (which, of course, operated at room temperature ambient conditions). Later, the Software Development and Validation Facility (SDVF) added a flight dynamics simulator hosted on a PDP-11/70 minicomputer.

Did you guys know that they used whale oil to lubricate the bearings and such on Hubble?

Not much of a market for whale oil these days.

For all it's faults, the Shuttle was still an amazing vehicle.

Perhaps the worst thing that Obama did was turning his back on America in Space.

According to NASA Administrator, Charles Bolden, Obama's core mission for NASA was to make Muslim countries feel good.
Wikipedia wrote:In a June 2010 interview with Al Jazeera, Bolden said that the top three goals he was tasked with by President Obama were to help re-inspire children to want to get into science and math, to expand NASA's international relationships, and, "perhaps foremost", "to reach out to the Muslim world ... to help them feel good about their historic contribution to science... and math and engineering".
What a clown.

There is a whole industry built around components destined for use in zero atmosphere environments. Many years ago someone discovered that some of the paints used colour coding resistors produced corrosive vapours in a vacuum, and when you can't just "pop it in a sonic then reflow the board" 'cos it's in orbit, that can be expensive...

Hubble is now fully operational.
The Hubble team was able to pinpoint the underlying problem in the Power Control Unit (PCU) of the telescope’s payload computer. It contains a power regulator which ensures a steady voltage supply of five volts to the payload’s computer hardware...... Thankfully though, the payload computer to blame for this issue was built with redundancy. Thus, a second computer is available for use in orbit in the event that a failure occurs.
