NASA’s Hubble telescope has been in a “coma” state since experiencing a system crash in late October.
NASA announced on December 7 that, after multiple instrument synchronization failures that forced the agency to put Hubble into safe mode, the telescope was back to normal operation, with all four instruments in active collection. data.
NASA said that, on December 6, the Hubble team restored the telescope’s imaging spectrometer, so that the last of the telescope’s instruments could be operational again after recent failures.
“The team will continue to develop and test changes to the instrument software that will allow them to conduct scientific operations even in the face of some lost sync notifications in the future,” NASA said. in the announcement of the return of Hubble.
Previously, on October 23, NASA first discovered that the Hubble instruments were not receiving synchronized notifications from the telescope’s control unit. Communication problems continued for several days, prompting NASA to put the telescope into safe mode.
This Hubble outage is the second in 2021. Before that, Hubble’s other month-long “coma” took place in July related to another incident.
The Hubble telescope is 31 years old and quite possibly nearing the end of its useful life in space. For now, though, NASA hopes Hubble will operate alongside the James Webb telescope within this decade. After several delays, the James Webb telescope is scheduled to launch on December 22.
