The Hubble Space Telescope will resume its usual duties again after a 3-week sleep mode. NASA reports that the orbital observatory resumed scientific observations at the weekend.
In early October, the directional control system of the telescope encountered a problem when the old gyroscope failed. Backup could not be carried out correctly, so I had to look for new options. The controllers managed to set up a backup gyroscope using various maneuvers and switches. Optimal performance needs the operation of three gyroscopes.
The telescope was launched into space in 1990 and conducted more than 1.3 million observations of stars, galaxies, black holes and other celestial targets. Some of them have been removed for 13 billion light years. The telescope returned to work on October 27, viewing a distant galaxy in the infrared region.
