Astronaut James Newman works with power ratchet tool in payload bay

In Discovery's cargo bay, astronaut James H. Newman works with the power ratchet tool (PRT). Astronaut Carl E. Walz, who joined Newman for the lengthy period of extravehicular activity (EVA), is partially visible in the background. The two mission specialists devoted part of their EVA to evaluating tools and equipment expected to be used in the Hubble Space Telescope servicing. A desert area in Africa forms the backdrop for the 70mm scene.
