The Hubble Space Telescope has been down for the past few days, NASA reports issue

The Hubble Space Telescope, which has been peering into the universe for more than 30 years, has been down for the past few days, NASA said Friday. The problem is a payload computer that stopped working last Sunday, the US space agency said. It insisted the telescope itself and scientific instruments that accompany it are “in good health.”

“The payload computer’s purpose is to control and coordinate the science instruments and monitor them for health and safety purposes,” NASA said. An attempt to restart it on Monday failed. NASA said initial evidence pointed to a degrading computer memory module as the source of the computer problem. An attempt to switch to a back-up memory module also failed.
