Hubble Space Telescope enters safe mode again due to gyroscope issues, leaving its future uncertain

The Hubble Space Telescope, which has been in operation for 34 years, recently entered safe mode due to ongoing gyroscope issues. This NASA/ESA observatory experienced a gyro glitch in 2023 that resulted in the suspension of science operations. However, the gyro problem has resurfaced, leading engineers to put the spacecraft back into safe mode while they work on finding a solution.

Despite the gyroscope issues, the Hubble and its instruments remain in good health. Currently, there are six gyroscopes onboard the Hubble, with only three still operational. These gyroscopes are crucial for determining the telescope’s direction and measuring its turn rate. While the Hubble can function on just one gyro, three are needed for optimal performance.

Having exceeded expectations after more than three decades in operation, the Hubble faces challenges as it nears its end. Without a Space Shuttle to service the telescope, replacing faulty parts becomes more difficult. Plans to retrieve the Hubble via a Space Shuttle have been shelved, leaving the observatory’s fate uncertain. However, there is hope for a future mission that could boost the spacecraft into a higher orbit.

The recent gyroscope issue has raised questions about the future of the Hubble space telescope. Despite its healthy instruments,
