NASA is still working to understand the malfunction of a venerable, out-of-service space observatory.
On October 25, the scientific instruments were shown on Hubble Space Telescope They entered safe mode, according to a brief statement released that day. In a longer statement published on Monday (November 2), NASA provided additional details about flaw And the agency’s plan to identify and address the cause of the observatory’s return to normal operations.
The entire agency staff wrote: “NASA continues to investigate why instruments in the Hubble Space Telescope recently entered safe mode configuration, halting scientific operations.” statment. “The tools are intact and will remain in a safe position while the mission team continues its investigations.”
According to the new statement, the devices stopped working at 2:38 AM ET (0638 GMT) on October 25. But the agency also pointed out something unprecedented: a similar glitch occurred two days ago but was quickly resolved.
“Hubble Science Instruments released error codes at 1:46 a.m. EDT on October 23, indicating a specific sync message was missing,” the statement read. “This message provides timing information that the tools use to properly respond to requests for data and commands. The expedition team reset the instruments, and scientific operations resumed the next morning.”
When the problem recurred, the error codes indicated “multiple sync message losses,” the statement notes noted, and Scientific Tools followed programming to automatically put themselves in safe mode.
According to the statement, Hubble personnel on Earth continue to analyze spacecraft data and are also working on actions that will lead to more data for study; This work will take at least a week to complete.
Hebel It was launched in April 1990; Since then, he has survived countless problems. The observatory is designed so that astronauts aboard the NASA space shuttle can visit the facility for repairs and upgrades; The last such mission flew in 2009 and the spacecraft has only been kept from Earth in the years since.
This current issue seems less serious than a computer glitch Hubble encountered this summer that affected the entire observatory, sidelining it for more than a month and requiring the team to switch Hubble to its backup hardware.
