No hasty fix for Hubble Effect Telescope’s computer glitch, NASA says

NASA is struggling to repair a pc glitch that has left the Hubble Effect Telescope offline for approximately two weeks — and its backup computer looks to maintain the the same discipline, too. 

The Hubble Effect Telescope, which launched in 1990, halted operations on June 13 true after 4 p.m. EDT (2000 GMT), following an discipline with seemingly the most telescope’s computers. Whereas the spacecraft has stopped collecting science facts, its other hardware and science instruments stay in true health, in step with an announcement from NASA. 

“Hubble has been looking on the universe for over 31 years,” NASA officials acknowledged within the statement. “It has contributed to about a of the largest discoveries of our cosmos, including the accelerating growth of the universe, the evolution of galaxies over time, and the necessary atmospheric stories of planets beyond our photo voltaic system.”

Hubble is equipped with two payload computers, each of which would be positioned on the Science Instrument and Repeat and Files Handling (SI C&DH) unit. The computers were installed in 2009, nonetheless were in-built the 1980s. Judicious seemingly the most computers serves as a backup; that unit was as soon as turned on for the necessary time in home within the route of assessments performed on June 23 and 24. This most up-to-date are attempting to revive the telescope published that every the necessary and backup computers are experiencing the the same error, which capability that the topic lies in varied locations, NASA acknowledged.

The necessary and backup computers are created from various pieces of hardware, which build functions equivalent to processing and storing operational instructions, coordinating and controlling the telescope’s science instruments, and supporting communications between varied parts of the spacecraft. The assessments conducted on June 23 and 24 showed that a enormous selection of combinations of these hardware pieces all experienced the the same error wherein instructions to write into or learn from memory were no longer a success, in step with the statement from NASA. 

Consequently, engineers are now investigating other hardware that would be inflicting the topic. This involves the Repeat Unit/Science Files Formatter (CU/SDF) — one other module on the SI C&DH that’s to blame for formatting and transmitting facts — and the energy regulator, which presents a fixed voltage supply to the computer’s hardware. “If the voltage is out of limits, it may perhaps possibly well perhaps reason the concerns noticed,” NASA officials wrote. 

NASA is persevering with assessments to additional isolate the allege and name a doable solution. If critical, the telescope can change over to the usage of its backup CU/SDF module or backup energy regulator, in step with the statement. 

Hubble went into a keeping “safe mode,” or electronic hibernation, when its necessary payload computer by surprise stopped working on June 13. Since then, NASA has been working to troubleshoot the topic and earn the telescope relief up and working. 

After a failed are attempting to restart the computer on June 14, the home agency made extra than one attempts to change over to seemingly the most telescope’s backup memory modules on June 16 and June 17. On the opposite hand, each these attempts to voice the backup memory module online were no longer a success. On June 22, the home agency shifted its point of interest to check the spacecraft’s No longer unique Interface (STINT) hardware and the computer’s Central Processing Module (CPM). 

Here’s no longer the necessary time that Hubble has experienced components in orbit. NASA launched a entire of five servicing missions to work on the telescope between 1993 and 2009. The aging telescope periodically experiences components; most no longer too lengthy ago, the telescope suffered a immediate instrument glitch in March, following a code modification to deal with gyroscope components.
