Hubble’s science operations stopped again

After a power outage last June (see below), which thankfully would have been the case It was resolved in JulyAnd Hubble Once again he has some concerns. In fact, tools telescope A spatial that contains more than 31 years of good and sincere service and reckon with him, You recently entered safe modeComment – hopefully only temporarily – scientific operations. The tools are fine and will remain in safe mode while running NASA Continue her investigations.

Scientific tools for Hubble issued symbols Error on October 23 at 1:46AM EST (EST; October 22 at 7:46PM EDT), indicating that a specific sync message was missing. This message provides the timing information that devices use to properly respond to data requests and commands. The mission team returned the instruments, and resumed scientific operations the next morning.

On October 25 at 2:38 AM EDT (October 24 at 8:38 PM EDT), the tools again issued error codes indicating that multiple sync messages were missing. As a result, they independently entered safe mode states as scheduled.

Mission team members evaluate spacecraft data and system diagrams to better understand the timing problem and how to solve it. They also develop and test procedures for collecting additional data from telescope. These activities should continue for at least a week.

The rest of the telescope is operating as expected.

Hubble has stopped working

The space telescope was launched in 1990 Hubble damage accumulates. NASA reported on June 16th The complete station forthe computer On the ship, it was observed on Sunday, June 13, shortly after 4 pm. The on-board computer, which controls all of the telescope’s instruments, went into inactive mode, apparently due to Memory Card defective. control center staff Goddard Space Flight Center NASA tried to restart the computer on Monday, but soon encountered the same problem.

This computer is not new: it was built in the 80s, and the memory card was replaced during the last mission of maintenance In 2009. This failure followed A series of other problems which have occurred on various instruments in recent years, and illustrate the aging condition of this telescope which can no longer be refurbished. Unfortunately, the launch of the James Webb Telescope which was scheduled to replace it in 2018, Never stop being late And nearly ten years behind schedule. Hopefully, it will be reliable because it is located 1.5 million km from Earth (versus 600 km from Hubble), and will not be accessible for maintenance.

Meanwhile, team Goddard Space Flight Center It tries to restart the computer in safe mode by switching to a backup memory card. If these efforts succeed, Hubble It will undergo tests for a day before restarting its scientific instruments. Otherwise, the notesUniverse It will create a huge void.

Hubble: returns to normal after gyroscope failure

Editorial article published on 10/24/2018

at NASA advertisement The Hubble telescope is back in operation again on Monday, October 22, 2018, and will resume its normal scientific activities soon. Everyone’s favorite space telescope has been closed since October 5 after a failure gyroscopeA necessary tool to guide it. NASA restarted and repaired the gyroscope between October 16-19. It seems that everything is back to normal, but the engineers will still undergo a series of tests before giving shooting Green when notes resume.

Hubble stopped after one of its gyroscopes failed

The Hubble’s spatial telescope At a standstill due to the failure of one of the gyroscopes that occurred last Friday. These tools allow him to orient himself well and are essential for making accurate notes. After a power outage, NASA put Hubble in safe mode (“Safe Mode”) and suspended all observations during the investigation.

Hubble Fully aware of gyroscope issues. In 2009, astronauts Replaced six gyroscopes during a maintenance mission. Half are now unusable, two are working properly and the other, which Hubble has just lost, shows signs of the end of life for a year. So the failure was no surprise. The space telescope usually uses three Gyros, but can continue its activities with one or two. The NASA He points out that this would have a relatively small effect on the quality of the observations, but would give them limited celestial coverage.
