STS-104, Mission Control Center Status Report # 06 Saturday, July 14, 2001 – 5:30 p.m. CDT

The five-member crew of Atlantis will spend today working in concert with the Expedition Two crew aboard
the International Space to install the station’s new airlock – Quest. The installation of that airlock will take
place as part of a seven-hour space walk by Mission Specialists Mike Gernhardt and Jim Reilly, scheduled to
begin at 9:09 p.m. Central.

The Shuttle crew’s day began at 4:04 p.m. with a wake-up call from Mission Control, playing the song
“Space Cowboy” by N’Sync for Mission Specialist Janet Kavandi. On board the Space Station, Commander
Yury Usachev and Flight Engineers Jim Voss and Susan Helms also awoke at 4:04 p.m.

During tonight’s space walk, Gernhardt, designated EV1, will be identifiable by the red stripes around the
legs of his spacesuit, while Reilly, EV2, will be wearing an all-white space suit. Atlantis’ pilot Charlie Hobaugh
will coordinate the space walk from within the shuttle cabin.

Gernhardt will begin the space walk by removing an insulating cover, nicknamed the “shower cap,” from the
airlock’s berthing mechanism, as well as protective covers from the mechanism’s seals. Reilly will work to
install bars on the airlock that will be used to attach four High-Pressure Gas Tanks during two subsequent
space walks later in the mission. Gernhardt will then disconnect heater cables that kept the airlock warm
while in the payload bay, which Reilly will stow along with the shower cap and berthing mechanism covers.

When the airlock is ready for installation, Helms, from a control panel in the station and assisted by
crewmate Voss, will attach the Canadarm2 to the Quest airlock and lift it out of Atlantis’ payload bay.
Grappling of the airlock by the station’s robotic arm is scheduled to occur at 11:04 p.m., with removal of the
airlock from the payload bay at 11:19 p.m. The airlock is scheduled to be attached to the right side of the
Unity module at 2:04 a.m.

Throughout the space walk, Atlantis astronaut Janet Kavandi will operate the shuttle’s robotic arm, using it
to maneuver the two space walkers around the space station and to provide camera views to assist Helms
and Voss with their work.

The next mission status report will be issued about 6 a.m. Sunday or as events warrant.
