Hubble’s Servicing Mission 3A

The Hubble Space Telescope, a vital tool for astronomy, faced challenges when its gyroscopes began failing. NASA responded by splitting the servicing mission into two parts, with Mission 3A focusing on repairing the gyroscopes. Despite delays, the mission launched in December 1999, successfully replacing gyroscopes, upgrading systems, and ensuring Hubble's continued operation. This mission demonstrated NASA's ability to adapt and maintain the telescope's functionality, allowing it to continue its scientific contributions.
