NASA’s beloved Hubble Space Telescope has faced one of its greatest challenges. A.. This week, of the problem and tried a new solution, and it seems to have worked.
“NASA has successfully switched to backup hardware on the Hubble Space Telescope, including turning on the backup payload computer on July 15.” the space agency announced on Friday.
The telescope has been in service for more than 30 years. The Hubble team had been considering the payload computer (hardware dating back to the 1980s) as the potential source of a memory problem. “A series of multi-day tests, which included attempts to restart and reconfigure the computer and the backup computer, were unsuccessful, but the information gathered from those activities has led the Hubble team to determine that the possible cause of the problem is in the Energy Control Unit, “NASA said.
As with the payload computer, the PCU is part of Hubble’s science instrument command and data handling unit. The PCU is responsible for supplying a constant and constant source of electricity to the computer and its memory. Hubble is equipped with many backup systems, including a replacement PCU.

Since the problem emerged on June 13, Hubble’s scientific work has stalled. The switch to backup hardware should give the telescope a new life. “The Hubble team is now monitoring the hardware to make sure everything is working properly,” NASA said. It will take more than a day to get science instruments out of safe mode before normal science operations can resume.
NASA operates Hubble in partnership with the European Space Agency. “We are very happy to announce that Hubble is back online!” ESA’s Hubble team tweeted on Friday. “Congratulations to the entire team that worked day and night to make this happen.”
There has been concern about the aging of the telescope. His successor, the long overdue, is still here on Earth, awaiting a possible launch in late 2021.
Hubble has overcome many technical glitches in its time, and it appears the venerable telescope will persevere through the latter. Wait, universe, Hubble is coming back.
