Hubble resumes full science operations
Engineers have now successfully reactivated the Hubble Space Telescope’s second spectrograph, so that the telescope is now fully operational for the first time since it went into safe mode on October 25th.
NASA’s Hubble Space Telescope team recovered the Space Telescope Imaging Spectrograph on Monday, Dec. 6, and is now operating with all four active instruments collecting science. The team has still not detected any further synchronization message issues since monitoring began Nov. 1.
The team will continue work on developing and testing changes to instrument software that would allow them to conduct science operations even if they encounter several lost synchronization messages in the future. The first of these changes is scheduled to be installed on the Cosmic Origins Spectrograph in mid-December. The other instruments will receive similar updates in the coming months.
Essentially, they are modifying the telescope’s software so that it will not shut down should it “encounter several lost synchronization messages.” As the engineers have never fully explained this issue, I suspect this is a work-around to ignore an issue that in the past they would have taken more seriously. Now they are doing a cost-benefit analysis, and have decided that ignoring some of these messages is better than fixing them. It might even be impossible to do so.
