Astronaut John M. Grunsfeld foreground, payload commander, is seen at one end of stowed solar panels in the cargo bay of the Space Shuttle Columbia while astronaut Richard M. Linnehan, mission specialist, uses the Remote Manipulator System's robotic arm to move around at the other end. They are participating in the first of five Extravehicular Activities EVAs of the mission. Linnehan and Grunsfeld are preparing to stow an old solar array in the Columbia's payload bay that will be replaced by a new one.
