NASA On Friday, it was said to have completed additional diagnostic tests in an attempt to identify a Problems with the Hubble Space Telescope’s (HST) payload computer.
This announcement comes after additional tests on Wednesdays, Thursdays and beyond spaceship Payload computers “discontinued” on June 13 and stopped collecting Scientific data.

in a statement, the agency noted that HST – named after a pioneer astronomer Edwin Hubble – and his scientific instruments are still “in good health and currently in a safe position.”
The telescope has two Payload computer, one of which has appeared, and is in the Science Instrument, Command and Data Handling (SI C&DH) unit.
The computer consists of a central processing unit (CPM), a standard interface (STINT), a communication bus, and one active memory unit, although there are three additional spare units.
The June 23 and June 24 tests involved turning on a backup computer for the first time in space, and the scientists found that several tests for both halves of the payload computer produced the same error and that the “command to write or read from memory” did not work.
Now, the agency is reported to have turned its attention to other devices, including the Command Unit/Scientific Data Coordinator (CU/SDF) in the SI C&DH unit.
According to the update, CU formats and sends commands and data to “specific destinations” which includes scientific instruments and the SDF format includes scientific data from scientific instruments to send to Earth.

The power regulator is also a likely culprit, and NASA says the team will continue to evaluate the hardware in C&DH’s SI module over the next week.
“If the team determines that the CU/SDF is a possible cause, they will recommend switching to a standby CU/SDF unit and standby power regulator.”
This is not the first time this year HST has run into problems.

In March, telescope “Goes to safe mode due to a software error on the plane.” Problem solved Only a few days later and science operations quickly resumed – even though the Wide Field Camera 3 (WFC3) tool was up and running It proved to be a bit more difficult.
HST was deployed by the space shuttle Discovery in 1990 and has been observing the universe for more than 31 years.
telescope Surveillance capabilities ‘highly developed’ As new and advanced scientific instruments were added during five missions to serve the astronauts.
HST has made more than 1.4 million observations over its lifetime—contributing to some of the universe’s most important discoveries—and has looked back at the universe’s past to locations more than 13.4 billion light-years away. Soil.
