Space telescope launched in 1990 Collecting damage. The ‘S full stop The boat was observed Sunday, June 13, after 4 p.m. The on-board computer that controls all of the telescope’s devices went into idle mode, for one reason or another. Defective. Control Center officials 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 1980s and replaced the memory card in the last mission It has happened on various devices in recent years, and the aging condition of this telescope cannot be reconstructed. Unfortunately, the launch of the James Webb telescope, which needs to be replaced in 2018, It is about ten years behind its initial schedule. We expect this to be reliable because it is located 1.5 million kilometers from Earth (600 km for Hubble), making it inaccessible to repair operations.This failure follows
In the meantime, the team Goddard Space Flight Center Switches to a backup memory card and tries to restart the computer in safe mode. If these attempts are successful, Its scientific instruments will be tested for a day before it can be restarted. Or, observations Will mark a large void.
Hubble: Back to normal after gyroscope failure
Editorial article published on 10/24/2018
At NASA a Hubble will be reactivated on Monday, October 22 and will resume its normal scientific operations soon. Everyone’s favorite space telescope has been closed since October 5 following the failure , The tool needed to orient it. Between October 16 and 19, NASA relaunched and repaired the gyroscope. Everything seems to be back to normal, but the engineers will run it through a series of tests before delivering Green when observations resume.
The rotation rate produced by the backup gyro has decreased and now they are within a normal range. Further tests are needed to ensure that Hubble can return to science with this gyro. For more information: https://t.co/lT2Wpycqw2 – Hubble (ASNASAHubble) October 22, 2018
Hubble stopped after one of the gyroscopes failed
Published on 09/10/2018
TheStopped due to failure of one of the gyroscopes that occurred last Friday. These tools allow him to orient well, which is essential for making accurate observations. Following the blackout, NASA put Hubble in safe mode («Safe Mode) All observations were stopped during the investigation.
The Hubble team is working to restart science after Hubble enters safe mode because one of the 3 gyros has failed. The backup gyro is being analyzed and tested to determine why it is not working as expected. For more information: https://t.co/T72X4pjLPI – Hubble (ASNASAHubble) 8 October 2018
Gyroscope is well aware of the problems. In 2009, Replaced six of its gyroscopes in a repair mission. Half of it is now useless, two are working properly, and the last one, which Hubble has now lost, shows signs of ending a year ago. So failure is not surprising. The space telescope usually uses three , But with one or two it can continue to function. The This suggests that it will have a relatively small impact on the quality of observations, but will provide more limited sky coverage.
