Hubble Space Telescope Operates with Single Gyroscope After Latest Safe Mode Entry
The Hubble Space Telescope, renowned for its significant contributions to astronomy since its launch in 1990, has once again demonstrated its resilience after a safe mode entry on November 23, 2022. This time, the telescope has been operating with just one gyroscope, a testament to its adaptability and the extensive preparation work carried out over the years.
NASA's latest effort to address a gyroscope issue on the Hubble Space Telescope has led to the telescope's transition to a newly developed science mode that requires only a single gyroscope for its pointing and control system. This change was made possible by the installation of six new gyroscopes during Hubble's fifth and final space shuttle servicing mission in 2009.
The gyroscope plays a crucial role in measuring the telescope's turn rates and ensuring it points in the desired direction. However, out of the six new gyroscopes installed, only three remain operational, with one exhibiting fluctuations. Despite this, the Hubble Space Telescope can continue its scientific operations efficiently, even with just one gyroscope if necessary.
The current gyroscope issue is not the first for the Hubble Space Telescope. It has bounced back from similar safe mode events in the past, including ones in 2008, 2018, and 2019. The telescope overcame a major computer glitch in June 2021 and another software issue earlier that year, demonstrating its ability to recover from setbacks.
NASA anticipates that the Hubble Space Telescope will recover from the current setback and continue its ongoing collaboration with other observatories, such as the James Webb Space Telescope. This collaboration is expected to extend throughout this decade and possibly into the next, ensuring Hubble's contribution to our understanding of the cosmos.
NASA has reassured the public that the Hubble Space Telescope's instruments remain stable, and the telescope is in overall good health. The safe mode entry on November 23 led to the suspension of science operations, but the telescope is expected to resume its scientific observations soon.

The Hubble Space Telescope's remarkable resilience and adaptability continue to amaze, ensuring its place as a cornerstone of astronomical research.
The Hubble Space Telescope, despite operating with only one gyroscope, continues to make significant contributions to space-and-astronomy, a testament to its technology and the extensive preparation work. NASA's latest safe mode entry has prompted a transition to a science mode requiring only a single gyroscope, aided by the installation of six new gyroscopes during a space shuttle mission in 2009. In the past, the telescope has bounced back from similar safe mode events and other technological setbacks, demonstrating its ability to recover from challenges. The telescope's ongoing collaboration with observatories, such as the James Webb Space Telescope, is expected to extend into the future, ensuring its continued influence in the field of science.
