Perrin on PFR in Endeavour's PLB during STS-111 UF-2 EVA 1

STS111-E-5036 (8 June 2002) --- Astronauts Philippe Perrin (left center) and Franklin R. Chang-Diaz (partially obscured by robot arm) work in chorus during extravehicular activity (EVA) to perform work on the International Space Station (ISS). The first spacewalk of the STS-111 mission began with the installation of a Power and Data Grapple Fixture (PDGF) for the station's robotic arm, known as Canadarm2, on the complex's P6 truss. The PDGF will allow the robotic arm to grip the P6 truss for future station assembly operations. Astronauts Chang-Diaz and Perrin (with French Space Agency, CNES) went on to install the new fixture about halfway up the P6 truss, the vertical structure that currently supports the station's set of large U.S. solar arrays.
