Chang-Diaz at work next to MBS in Endeavour's PLB during STS-111 UF-2 EVA 1

STS111-306-023 (9 June 2002) --- Astronaut Franklin R. Chang-Diaz, STS-111 mission specialist, participates in the first scheduled session of extravehicular activity (EVA) for the STS-111 mission. During the spacewalk, Chang-Diaz and Perrin attached a Power and Data Grapple Fixture onto the International Space Station’s (ISS) P6 Truss, setting the stage for the future relocation of the P6. The next major task was to remove Service Module Debris Panels from Space Shuttle Endeavour’s payload bay and attach them to their temporary location on Pressurized Mating Adapter 1 (PMA-1). The spacewalkers also removed thermal blankets to prepare the Mobile Base System (MBS) for installation onto the station’s Mobile Transporter (MT).
