Hubble Space Telescope

It may be noted that some time ago a problem occurred in a payload computer of the ‘Hubble Space Telescope’, due to which it stopped working.

NASA has recently succeeded in replacing it with a backup computer mounted on the ‘Hubble Observatory’.


On June 13, the Hubble Telescope stopped working after a payload computer malfunctioned. With the help of this computer, the instruments related to science were controlled in the telescope.
