The Hubble Space Telescope is on the highway again from its newest glitch, nevertheless it’s not near the end line but.
In late October, the well-known observatory skilled an issue with the synchronization of its inside communications, which knocked all 5 of its science devices offline. The Hubble group bought a kind of devices, the Advanced Camera for Surveys (ACS), back up and running on Nov. 7, however the different 4 stay in a protecting “safe mode.”
Hubble’s handlers proceed to work to get these 4 operational as effectively, and so they’ve made some progress lately. For instance, through the previous week, “the Hubble team has identified near-term changes that could be made to how the instruments monitor and respond to missed synchronization messages, as well as to how the payload computer monitors the instruments,” NASA officers wrote in a Hubble update on Tuesday (Nov. 16).

“This would allow science operations to continue even if several missed messages occur,” they added. “The team has also continued analyzing the instrument flight software to verify that all possible solutions would be safe for the instruments.”
Over the approaching week, the group will check the efficacy of those potential modifications and begin mapping out a restoration order for the 4 safe-mode devices. It will in all probability take a number of weeks to finish this work for the primary instrument chosen, whichever one which seems to be, NASA officers stated. So a full restoration for Hubble isn’t precisely simply across the nook.
As this work proceeds, the Hubble group may even begin attempting to get well the Wide Field Camera 3 instrument with no new modifications, as was achieved efficiently with the ACS earlier this month, “as an interim and low-risk step toward resuming normal science operations,” NASA officers wrote in Tuesday’s replace.
Hubble launched to Earth orbit in April 1990. The well-known scope has overcome various issues and challenges in its storied profession — most famously, a flawed main mirror, which was mounted by spacewalking astronauts in 1993. Astronauts repaired, maintained and upgraded the Hubble on 4 extra servicing missions after that, the final of which occurred in 2009.
Hubble’s 5 predominant science devices as we speak are the ACS, Wide Field Camera 3, Cosmic Origins Spectrograph, Space Telescope Imaging Spectrograph and the Near Infrared Camera and Multi-Object Spectrometer. The telescope’s positive steerage sensors can, and typically do, make scientific observations as effectively.
