Hubble Space Telescope and Tools in Space

The video features NASA astronaut John Grunsfeld and EVA manager Russ Warith discussing the Hubble Space Telescope. They explain the initial issues with Hubble's mirror and the 1993 mission to correct it using the Corrective Optics Space Telescope Axial Replacement. The video highlights the design of Hubble for easy maintenance and the tools used, such as the power ratchet tool. It also covers the functionality and safety of tools in space, emphasizing the importance of upgrading Hubble with new technology to continue unraveling the universe's mysteries.
