The Hubble Space Telescope operated since 1990 has been down for the past few days, NASA said on Friday. The Hubble Space Telescope is revolutionary in the field of astronomy as it sent back images of the solar system, the Milky Way and distant galaxies, which changes our vision and knowledge of the universe.
NASA on June 18 tweeted “NASA continues to work to resolve an issue with the payload computer on the Hubble Space Telescope, which halted on June 13. Launched in 1990, Hubble has contributed greatly to our understanding of the universe over the past 30 years.”
NASA said that the problem is a payload computer that stopped working last Sunday. It insisted the telescope itself and scientific instruments that accompany it are "in good health."
NASA also said that “The payload computer's purpose is to control and coordinate the science instruments and monitor them for health and safety purposes."
Also, an attempt to restart it on Monday failed, it may due to a degrading computer memory module as the source of the computer problem. An attempt to switch to a backup memory module also failed.
The technology for the payload computer dates back to the 1980s, and it was replaced during maintenance work in 2009. A new and more powerful one, called the James Webb Space Telescope, is scheduled to be deployed late this year. It is designed to view much deeper into space than ever before.
