NASA is constant to analyze why the devices within the Hubble Space Telescope lately went into secure mode configuration, suspending science operations. The devices are wholesome and can stay in secure mode whereas the mission workforce continues its investigation.
Hubble’s science devices issued error codes at 1:46 a.m. EDT on October 23, indicating the lack of a particular synchronization message. This message offers timing info the devices use to accurately reply to knowledge requests and instructions. The mission workforce reset the devices, resuming science operations the next morning.
At 2:38 a.m. EDT, on October 25, the science devices once more issued error codes indicating a number of losses of synchronization messages. Because of this, the science devices autonomously entered secure mode states as programmed.
Mission workforce members are evaluating spacecraft knowledge and system diagrams to raised perceive the synchronization subject and learn how to handle it. Additionally they are creating and testing procedures to gather extra knowledge from the spacecraft. These actions are anticipated to take at the very least one week.
The remainder of the spacecraft is working as anticipated.
