Why was the Hubble computer in safe mode? | Digital Trends Spanish


A computer failure is the one that caused a setback in the hubble space telescope on June 13. According to NASA, the payload computer suffered a setback and had trouble accessing the backups.

“Scientific instruments will remain in a safe mode state until the problem is resolved. The telescope itself and the scientific instruments remain in good health, “said the US Space Agency.

The chronology of the POT indicates that on June 13 the computer stopped and on June 14 after trying to restart the computer, an error was caused that led to activate the safe mode.

The payload computer is a NASA Standard Spacecraft Computer-1 (NSSC-1) system built in the 1980s that is housed in the Data Management and Scientific Instruments Command unit. The purpose of the computer is to control and coordinate scientific instruments and monitor them for health and safety purposes.

There is also a mirror computer that serves to replace the current one in case of repeated failure.

NASA further adds that “both computers can access and use any of the four independent memory modules, each of which contains 64 KB of complementary metal oxide semiconductor (CMOS) memory. The payload equipment uses only one memory module operationally at a time, with the other three serving as backups. “

The Hubble Space Telescope was deployed on April 25, 1990 from the Space Shuttle Discovery.
