The Final Mission: Repairing the Hubble Space Telescope

The video discusses the Hubble Space Telescope's design for on-orbit repair, enabled by the reusable space shuttle. It highlights the challenges faced in maintaining Hubble, especially after the Columbia disaster, which limited shuttle missions. The video details the fourth and most ambitious service mission to Hubble, involving new solar panels, an advanced camera, and a critical power control unit replacement. Despite technical challenges, including cooling issues and a delayed spacewalk, the mission was completed successfully. This marked the final visit to Hubble, a significant scientific instrument.
