Glitches Send Hubble Space Telescope Into Safe Mode – NASA Team Investigating

Hubbles science instruments released error codes at 1:46 a.m. EDT on October 23, indicating the loss of a particular synchronization message. This message supplies timing information the instruments utilize to properly respond to information requests and commands. The objective group reset the instruments, resuming science operations the following morning.

Objective employee are evaluating spacecraft information and system diagrams to much better comprehend the synchronization problem and how to resolve it. They likewise are developing and evaluating treatments to collect extra data from the spacecraft. These activities are anticipated to take at least one week.
The rest of the spacecraft is running as anticipated.

NASA is continuing to investigate why the instruments in the Hubble Space Telescope recently went into safe mode configuration, suspending science operations. The instruments are healthy and will remain in safe mode while the mission group continues its examination.
Hubbles science instruments released mistake codes at 1:46 a.m. EDT on October 23, suggesting the loss of a particular synchronization message. This message offers timing information the instruments utilize to properly react to data demands and commands. The objective group reset the instruments, resuming science operations the following morning.
At 2:38 a.m. EDT, on October 25, the science instruments once again issued mistake codes indicating numerous losses of synchronization messages. As a result, the science instruments autonomously got in safe mode states as programmed.
