US astronomers want a new space-based telescope to search for exoplanets, and perhaps the project can’t come soon enough. The Hubble Space Telescope’s scientific operations are on hold for the second time this year. After an extended offline period this summer, Hubble is in ‘Safe Mode’ as NASA scientists investigate what’s gone wrong with the telescope.
NASA writes, ‘NASA is continuing work to resolve an issue that has suspended science operations on the Hubble Space Telescope. The science instruments entered a safe mode configuration on Oct. 25 after detecting a loss of specific data synchronization messages.’ The Hubble team is working to isolate the problem on circuitry in the Control Unit hardware that is part of the Science Instrument Command and Data Handling Unit. The Control Unit generates synchronization messages for the onboard instruments.

In addition to analyzing instruments, the team is also working to figure out a workaround for the issue, including ways to possibly change the instrument flight software to check for lost messages and compensate for them without instruments needing to go into safe mode. Possible workarounds would first be tested using ground simulators.
