STS-111 Flight Day 7 Highlights

On Flight Day 7 of STS-111 (Space Shuttle Endeavour crew includes: Kenneth Cockrell, Commander; Paul Lockhart, Pilot; Franklin Chang-Diaz, Mission Specialist; Philippe Perrin, Mission Specialist; International Space Station (ISS) Expedition 5 crew includes Valery Korzun, Commander; Peggy Whitson, Flight Engineer; Sergei Treschev, Flight Engineer; ISS Expedition 4 crew includes: Yury Onufrienko, Commander; Daniel Bursch, Flight Engineer; Carl Walz, Flight Engineer), this video opens with answers to questions asked by the public via e-mail about the altitude of the space station, the length of its orbit, how astronauts differentiate between up and down in the microgravity environment, and whether they hear wind noise during the shuttle's reentry. In video footage shot from inside the Quest airlock, Perrin is shown exiting the station to perform an extravehicular activity (EVA) with Chang-Diaz. Chang-Diaz is shown, in helmet mounted camera footage, attaching cable protection booties to a fish-stringer device with multiple hooks, and Perrin is seen loosening bolts that hold the replacement unit accomodation in launch position atop the Mobile Base System (MBS). Perrin then mounts a camera atop the mast of the MBS. During this EVA, the astronauts installed the MBS on the Mobile Transporter (MT) to support the Canadarm 2 robotic arm. A camera in the Endeavour's payload bay provides footage of the Pacific Ocean, the Baja Peninsula, and Midwestern United States. Plumes from wildfires in Nevada, Idaho, Yellowstone National Park, Wyoming, and Montana are visible. The station continues over the Great Lakes and the Eastern Provinces of Canada.
