NASA confirmed that the Hubble Space Telescope, which is a beloved connection with the cosmos, entered safe mode on Nov. 23 — the third time since Nov. 19. Although, the observatory’s health remains good, and scientists are working on resolving the issue to reactivate Hubble.
The root problem lies with the gyroscopes, which are integral to the telescope’s operation. Gyroscopes help determine the direction the object is facing. Specifically, the gyroscopes on the Hubble Space Telescope measure the telescope’s turn rates, which are crucial for directional readings.
In 2009, six new gyroscopes were installed on Hubble during the fifth and final space shuttle servicing mission. However, only three remain operational, with one of them currently causing issues.
The faulty gyroscope has been providing fluctuating readings, sending Hubble into safe mode on various occasions. However, this isn’t the first time the telescope has faced such setbacks. In 2018, Hubble entered safe mode for a similar issue, and still managed to come back online and capture stunning images of the galaxy.
Despite this, Hubble doesn’t necessarily need to use all three remaining gyroscopes. NASA believes the telescope can function adequately with just one, indicating that it will continue to be operational for the foreseeable future.
Since its launch in 1990, the Hubble Space Telescope has been a staple of astronomical research and discovery.
