Engineers at NASA are persevering with work to repair the troubled Hubble Space Telescope, which is experiencing issues for the second time this 12 months.

The downside started on October 25, when the science devices mechanically switched to secure mode as they’re programmed to do when a problem happens. This places the devices right into a fundamental working mode through which they don’t acquire any science information and ensures that the devices aren’t broken by any defective instructions. The difficulty appears to be an issue with information synchronization.

Most of the devices on the Hubble Space Telescope stay in secure mode following a synchronization difficulty. NASA

The first step to gathering extra information about the issue was for the crew to activate an previous and unused instrument, Near Infrared Camera and Multi Object Spectrometer (NICMOS) instrument. This instrument hasn’t been utilized in 11 years because it has been outdated by the Wide Field Camera 3, so the crew may use NICMOS to gather data on the issue with out risking the lively devices.

Next, the engineers moved on to turning again on a key Hubble instrument known as the Advanced Camera for Surveys, which was recovered on November 7. This step was profitable, permitting the engineers to be taught extra about what the issue is with the synchronization difficulty.

“The Hubble team successfully recovered the Advanced Camera for Surveys instrument Nov. 7,” NASA wrote in an replace. “The instrument has started taking science observations once again. Hubble’s other instruments remain in safe mode while NASA continues investigating the lost synchronization messages first detected October 23. The camera was selected as the first instrument to recover as it faces the fewest complications should a lost message occur. ”

The excellent news is that this a part of the restoration course of appears to have gone nicely, although engineers are very cautious when turning on and testing methods as it might be extraordinarily tough to get an in-person mission to repair Hubble if something went significantly unsuitable with the telescope. The engineers thus work remotely and really rigorously to attempt to anticipate any potential points.

“Over the past week, the mission team has continued investigating the root cause of the synchronization issues and has seen no additional problems,” NASA wrote. “The team will continue looking into possible short-term solutions this week and develop estimates for implementation. Once this occurs, the team will discuss returning the other instruments to operational status and resuming their science observations.”
