The Hubble Space Telescope has temporarily stopped observing the cosmos.
The National Aeronautics and Space Administration (NASA) said the telescope slipped into a hibernating state more than a week ago when one of its three remaining gyroscopes "part of the pointing system" malfunctioned, stated a report by PTI.
The same device has been acting up for months and disrupting scientific operations.
Hubble remains safe but inactive as flight controllers figure out how to proceed, officials said.
The space agency planned to outline a path forward on Tuesday, June 4.
Hubble got six new gyroscopes during astronauts' final visit in 2009.
The devices' spinning wheels keep the telescope stable and looking the right way by tracking Hubble's rotation and position in space.
Three gyroscopes no longer function.
NASA said the 34-year-old observatory could keep making discoveries with only one or two good gyroscopes.
Space shuttle Discovery delivered Hubble to orbit on April 24, 1990.
Its bigger and more powerful successor, the Webb Space Telescope, launched in 2021, stated the report by PTI.
"After careful consideration, work is underway to transition @NASA's Hubble Space Telescope to operate using only one gyroscope. This change will allow Hubble to continue making important observations through this decade and into the next," says a tweet posted on X by the official X handle of NASA.
