NASA revives ailing Hubble Space Telescope with switch to backup computer

On June 13, Hubble shut down after a payload computer from the 1980s that handles the telescope’s science instruments suffered a glitch. Now, over a month since Hubble ran into issues, which the Hubble team thinks were caused by the spacecraft’s Power Control Unit (PCU), NASA switched to backup hardware and was able to switch the scope back on.’

With Hubble back online with this backup hardware, the Hubble team is keeping a close watch to make sure that everything works correctly, according to a statement from NASA.’

Hubble returns to normal operations after switch to backup computer

WASHINGTON ‘ NASA’s Hubble Space Telescope returned to science operations July 17 after a hiatus of more than a month as controllers successfully switched the orbiting observatory to a backup payload computer.

NASA said the instruments of the 31-year-old telescope are now operational nearly five weeks after a payload computer, which commands those instruments, malfunctioned. Those instruments will resume normal science observations after completing calibrations.

After weeks of investigation, engineers concluded that the most likely cause of the payload computer problem was a malfunction of a power control unit, which supplies voltage to the hardware in the computer. With no ability to reset the power control unit from the ground, engineers decided to switch to the backup Science Instrument Command and Data Handling hardware, which has its own power control unit.

NASA has finally fixed the Hubble Space Telescope after almost 5 weeks of troubleshooting a mysterious glitch

Even though NASA has probably fixed the issue, it’s a sign that Hubble’s age may be starting to interfere with its science. The telescope hasn’t been upgraded since 2009, and some of its hardware is more than 30 years old.

“This is an older machine, and it’s kind of telling us: Look, I’m getting a little bit old here, right? It’s talking to us,” Zurbuchen said. “Despite that, more science is ahead, and we’re excited about it.”

It’s still not totally clear which piece of hardware was the culprit. Engineers suspect that a failsafe on the telescope’s Power Control Unit (PCU) instructed the payload computer to shut down. The PCU could have been sending the wrong voltage of electricity to the computer, or the failsafe itself could have been malfunctioning.

Nasa is preparing to reboot the Hubble Space Telescope

Nasa has identified a potential fix for the Hubble Space Telescope, which has spent the last month in ‘safe mode’.

A technical glitch caused the orbiting satellite to suspend its scientific operations and Nasa has spent the last few weeks trying to figure out how to fix it.

Experts at Nasa reckon the problem is to do with the payload computer ‘ a piece of technology on board that dates back to the 1980s.

‘A series of multi-day tests, which included attempts to restart and reconfigure the computer and the backup computer, were not successful, but the information gathered from those activities has led the Hubble team to determine that the possible cause of the problem is in the Power Control Unit (PCU),’ the space agency explained.

Operations underway to restore payload computer on NASA’s Hubble Space Telescope

NASA has identified the possible cause of the payload computer problem that suspended Hubble Space Telescope science operations on June 13. The telescope itself and science instruments remain healthy and in a safe configuration. The payload computer resides in the Science Instrument Command and Data Handling (SI C&DH) unit. It controls, coordinates, and monitors Hubble’s science instruments. When the payload computer halted, Hubble’s science instruments were automatically placed into a safe configuration. A series of multi-day tests, which included attempts to restart and reconfigure the computer and the backup computer, were not successful, but the information gathered from those activities has led the Hubble team to determine that the possible cause of the problem is in the Power Control Unit (PCU).
