NASA revives ailing Hubble Space Telescope with switch to backup computer

The Hubble Space Telescope has powered on once again! NASA was able to successfully switch to a backup computer on the observatory on Friday (July 16) following weeks of computer problems. 

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.
