NASA's Hubble Telescope Hits Pause To Science Missions; Here's Why

NASA's Hubble Space Telescope, known for its groundbreaking discoveries and stunning images of the cosmos, has temporarily paused its science operations.NASA is actively working to resume science operations for the Hubble Space Telescope after it entered safe mode on April 23, 2024, due to a recurring gyroscope malfunction, the space agency confirmed in a blog post.

Despite the setback, Hubble's instruments are stable, and the telescope remains in good health. The main issue is a faulty reading from one of Hubble's three gyroscopes. When will it resume working? Know what NASA has said.

What Is Gyroscope GlitchThe telescope automatically transitioned into safe mode when one of its three gyroscopes detected irregular readings. Gyroscopes are crucial components that measure the telescope's turn rates and help determine its orientation. The Gyro "are part of the system that determines which direction the telescope is pointed," NASA added.

However, this is not the first time this particular gyro has caused issues; a similar incident occurred in November 2023 after returning similar errors in the readings. NASA engineers are currently working to identify potential solutions to address the gyroscope issue, including the possibility of reconfiguring the spacecraft to operate with only one gyro, while keeping the remaining operational gyro in reserve.

NASA’s Future Plans For Hubble TelescopeDespite the ageing of the spacecraft, the team remains optimistic about finding a solution and restoring full functionality. Originally equipped with six gyros during its final servicing mission in 2009, Hubble now relies on three operational ones "but could continue to make science observations with only one gyro if required. NASA anticipates Hubble will continue making groundbreaking discoveries, working with other observatories, such as the agency’s James Webb Space Telescope, throughout this decade and possibly into the next." However, using only one gyro may decrease efficiency.

It must be noted that launched in 1990, Hubble has contributed to the understanding of the universe and continues to be a vital tool for astronomers worldwide. The telescope has recently celebrated its 34th anniversary in orbit.
