The NASA Pistol Grip Tool (PGT) used during the Hubble Space Telescope servicing missions was a versatile and essential piece of equipment for astronauts conducting extravehicular activities (EVAs) in the vacuum of space. This handheld device, resembling a cordless power drill, featured a compact design optimized for use in the microgravity environment. Equipped with interchangeable bits and a pistol grip handle, the PGT enabled astronauts to efficiently perform a wide range of tasks during their spacewalks, from loosening and tightening bolts to securing delicate components with precision. Its ergonomic design included intuitive controls and tactile feedback, allowing astronauts to operate it effectively while wearing bulky spacesuits. The PGT's robust construction and reliability were crucial for the success of the Hubble servicing missions, facilitating intricate repairs and upgrades to the iconic space telescope.
