STS105-E-5292 (16 August 2001) --- Astronaut Patrick G. Forrester works with the Early Ammonia Servicer (EAS), which he and fellow spacewalker Daniel T. Barry (out of frame) are in the process of installing on a segment of the P6 structure on the International Space Station (ISS). The two mission specialists were participating in the first of two scheduled STS-105 space walks. During the space walk, Discovery's commander Scott J. Horowitz operated the shuttle robot arm, and pilot Frederick W. (Rick) Sturckow choreographed the space walk from the orbiter's flight deck. The image was recorded with a digital still camera.
