Hubble Space Telescope Operations

The video covers the Hubble servicing mission, highlighting five back-to-back spacewalks. Key tasks include replacing the Wide Field Camera, gyroscopes, and repairing the Space Telescope Imaging Spectrograph. The mission involves innovative tool design to handle non-captive screws, ensuring successful repairs and upgrades to the Hubble Space Telescope.
