NASA reported that the Hubble Space Telescope stopped working a week ago, on the evening of June 13, due to a failure in the memory module of the payload’s onboard computer. Attempts to fix the failure so far have been unsuccessful, so conduct scientific research unit can not yet.
According to representatives of the space agency, the telescope itself and other scientific instruments are in good condition. However, since the onboard computer payload is responsible for managing and coordinating the scientific instruments on board, due to failure in the transmission of signals to the main computer, the entire scientific activities of the telescope stopped. Last Monday, June 14, experts have tried to restart the system, but they failed to do so.
The reason, according to NASA, was damage to one of the four modules of solid-state memory capacity of 64 KB, yet revive the telescope by switching to a backup module also failed.
The payload computer, known as NASA’s Standard Space Computer-1, or NSSC-1, was developed in the 1980s and is part of the control and processing unit for the telescope’s scientific instruments. This system is redundant, meaning there is a backup of the NSSC-1, but only one memory module is always working and the other three are on standby.
As of June 18, engineers were still running diagnostics on the system before trying to switch to the backup computer. According to a NASA statement, the telescope’s scientific instruments will remain in safe mode until the problem is resolved.
