Senator Barbara Mikulski Examines Repair Tools

Senator Barbara Mikulski holds tools used to repair instruments on the Hubble Space Telescope during servicing missions, joined by astronaut Paul Richards (far right). Mikulski is holding a mini power tool with interchangeable screwdriver bits. The screwdriver is connected to a battery pack to make the tool smaller and easier to handle. Pictured on the left are color-coded screwdriver bits in a bit caddy.
