Endeavour Astronauts Franklin Chang-Diaz and Philippe Perrin completed all scheduled International Space Station assembly tasks today during a 7-hour, 14-minute spacewalk, the first ever for the duo.

Chang-Diaz and Perrin ventured outside the station’s Quest airlock at 10:27 a.m. Central time. With the help of Endeavour Pilot Paul Lockhart, who guided the spacewalk from inside the shuttle, Chang-Diaz and Perrin first installed a Power and Data Grapple Fixture to the station’s P6 truss. The fixture will be used to relocate the P6 truss structure to its final location on the station.

Attached to a foot restraint at the end of the station’s robotic arm, Canadarm2, operated by Expedition Five Flight Engineer Peggy Whitson and ISS Commander Valery Korzun, Chang-Diaz gathered six micrometeoroid debris shields from the shuttle cargo bay and, with help from Perrin, temporarily stored them on Pressurized Mating Adapter-1 which links Unity to Zarya. Whitson and Korzun will install the shields on the Zvezda Service Module during a spacewalk set for late July.

Chang-Diaz then conducted a visual and photographic inspection of one of the station’s four control moment gyroscopes on the station’s Z1 truss, a task that was added to today’s spacewalk after the gyroscope experienced a mechanical failure yesterday. The photos may help ground controllers better understand why the gyroscope failed.

Removal of thermal blankets from the Mobile Remote Servicer Base System or MBS was the final task of the spacewalk. At 5:21 p.m. Endeavour Commander Ken Cockrell commanded the release of latches that had secured the MBS to its carrier in the payload bay. Whitson and Carl Walz then latched onto the MBS with Canadarm2, removed it from its carrier, and maneuvered it to a position about three feet above the station’s railcar, the Mobile Transporter. Canadarm2 will be left in a parked position overnight to thermally condition the MBS before it is mated to the railcar Monday.

Later, the Canadarm2 robotic arm will be commanded to “walk off” its position attached to the Destiny Laboratory onto a Power and Data Grapple Fixture atop the MBS. The arm will then be able to move up and down along the station truss for use in future assembly operations.

Following an inventory of the tools they used during the spacewalk, Perrin and Chang-Diaz re-entered Quest. Airlock repressurization began at 5:41 p.m. Central time, signaling the end of the spacewalk. The next STS-111 status report will be issued Monday morning, or earlier, if events warrant.

STS-111 Extravehicular Activities

The STS-111 crew will perform three spacewalks, which are also known as extravehicular activities, to continue the assembly of the International Space Station. All three extravehicular activities, or EVAs, will be based out of the station’s Quest Airlock.

  • EVA Astronauts and Suit ID

    – Franklin Chang-Dìaz (EV1): solid red stripes

    – Philippe Perrin (EV2): solid white suit

  • Station Robot Arm Operator: Carl Walz

  • Shuttle Robot Arm Operator: Ken Cockrell

  • Spacewalk Coordinator: Paul Lockhart

    EVA 1

    Chang-Dìaz, Perrin

    6 hours

    Start Time: 10:08 a.m. CDT (1508 GMT) June 9, 2002

    End Time: 4:08 p.m. CDT (2108 GMT) June 9, 2002

    During STS-111’s first spacewalk, Chang-Dìaz and Perrin will attach a Power and Data Grapple Fixture onto the International Space Station’s P6 Truss, setting the stage for the future relocation of the P6. The next major task will be 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. The shields will be installed onto the Zvezda Service Module later by future stations crewmembers. Then, the spacewalkers will remove thermal blankets to prepare the Mobile Base System, or MBS, for installation onto the station’s Mobile Transporter. Expedition Four Flight Engineer Carl Walz will use the station’s robot arm, Canadarm2, to lift the MBS out of the payload bay after Chang-Dìaz and Perrin have finished. The MBS will be installed onto the Mobile Transporter on Flight Day 6.

    EVA 2

    Chang-Dìaz, Perrin

    6 hours, 30 minutes

    Start Time: 10:08 a.m. CDT (1508 GMT) June 11, 2002

    End Time: 4:38 p.m. CDT (2138 GMT) June 11, 2002

    The second STS-111 spacewalk will focus on outfitting and permanently attaching the MBS to the MT. Chang-Dìaz and Perrin will attach power, data and video cables from the station to the MBS. Then, they will use a power wrench to complete the attachment of the MBS onto the MT.

    EVA 3

    Chang-Dìaz, Perrin

    7 hours

    Start Time: 9:43 a.m. CDT (1443 GMT) June 13, 2002

    End Time: 4:43 p.m. CDT (2143 GMT) June 13, 2002

    Canadarm2’s wrist roll joint will be replaced during STS-111’s third spacewalk. After replacing the joint on the arm, the spacewalkers will stow the old joint in Endeavour’s payload bay for the journey home.
