Mission Summary:

The crew included teacher-in-space Barbara Morgan. Main payloads were the S5 Truss, SPACEHAB Pressurized Module and External Stowage Platform-3. Endeavour docked to the International Space Station (ISS) at 2:02 p.m. EDT on August 10, 2007. There were four spacewalks during the mission.

The first spacewalk occurred on August 11, 2007 and lasted 6 hours, 17 minutes. Astronauts Mastracchio and Williams added the two-ton, eleven-foot spacer, the Starboard 5 segment of the ISS Truss, to ISS. They also retracted the forward heat-rejecting radiator from the P6 Truss.

The second spacewalk occurred on August 13, 2007 and lasted 6 hours, 28 minutes. Astronauts Williams and Mastracchio installed the 600-pound Control Moment Gyroscope onto the ISS Z1 segment of the truss, replacing a failed unit.

The third spacewalk occurred on August 14, 2007 and lasted 5 hours, 28 minutes. Astronaut Mastracchio and ISS Flight Engineer Clay Anderson relocated the S-band antenna sub-assembly from the P6 Truss to the P1 Truss, installed a new transponder on P1 and retrieved a P6 transponder. During the spacewalk, astronaut Mastracchio noted a hole on the thumb of his left glove. The hole was on the second of five layers and did not pose a hazard. But as a precaution, Mastracchio ended the spacewalk early.

The fourth spacewalk occurred on August 18, 2007 and lasted 5 hours. Astronaut Williams and ISS Flight Engineer Anderson installed the External Wireless Instrumentation System antenna, attached a stand for the Shuttle’s robotic arm extension boom and retrieved two materials experiment containers from outside ISS.
