Hubble stopped working
NASA said in its blog post that the agency is working to reactivate science operations of the Hubble Space Telescope after it entered safe mode on November 23 due to an ongoing gyroscope issue. The agency underlined that Hubble’s instruments are stable and the telescope is healthy.
NASA stated that one of Hubble’s three gyroscopes entered safe mode because it gave erroneous measurements. For those who don’t know, Hubble’s gyroscopes measure the spin rate of the telescope, which is part of the system that determines which direction the telescope is pointing.
According to the statement, Hubble first went into safe mode on November 19. Although the operating team successfully recovered the spacecraft to continue observations the next day, the unstable gyroscope caused the observatory to suspend science activities once again on November 21. After a successful recovery, Hubble entered safe mode once again on November 23.
Three working gyroscopes left
NASA predicts that Hubble will continue to make groundbreaking discoveries throughout this decade and possibly into the next, working with the agency’s other observatories, such as the James Webb Space Telescope. However, this is not the first time Hubble has gone offline. The space observatory went into safe mode in June due to a problem in its computer systems.
