STS-112 MCC Status Report #10 
Saturday, October 12, 2002 - 5 a.m. CDT 
Mission Control Center, Houston, Texas 

Focus of attention aboard Space Shuttle Atlantis and the International
Space Station once again is outside the complex as Astronauts Dave Wolf
and Piers Sellers conduct the second of three planned spacewalks to bring
the station's newest component  the Starboard 1 (S1) Truss  to life. 

The Extravehicular Activity, or EVA, is set to begin about 9:40 this
morning and is planned to last about 6 ½ hours. It includes installation
of devices to prevent pressure buildup in line fittings; connecting
cooling system lines; removing launch restraints from a radiator which
will be deployed Sunday, and installing a second camera. 

The Spool Positioning Devices (SPDs) are designed to prevent pressure
buildup in Quick Disconnect fittings, which could make it impossible to
disconnect fittings, if necessary. Sellers and Wolf will install 24 of
the devices  most of which are on ammonia lines  during the spacewalk. 

Sellers, in the all-white spacesuit, will ride the station's robotic arm
to the S1 Truss worksite to hook up nitrogen lines used to pressurize the
ammonia system, while Wolf, wearing the suit with red stripes, releases
launch restraints on the Crew and Equipment Translation Aid  a handcar
on the truss rails. Peggy Whitson, NASA ISS science officer, and
Atlantis' Sandy Magnus will operate the robot arm. As with the first
spacewalk Thursday, Pilot Pam Melroy will choreograph the EVA from
Atlantis' flight deck. 

Prior to the spacewalk, Commander Jeff Ashby and Melroy will gently raise
the altitude of the station by firing small thrusters on Atlantis. This
reboost maneuver will increase the altitude of the complex from 238
statute miles (383 kilometers) to 242 sm (389 km). 

Atlantis' crew was awakened at 2:46 a.m. today by the song "Push It,"
performed by the group Garbage. It was for Sellers, requested by his
family. The station crew woke up about 30 minutes later. 

Atlantis and station crewmembers are scheduled to go to bed about 7:30
tonight and the next status report will be issued at about that time, or
earlier if events warrant.
