In the White Room, members of the closeout crew help STS-98 Mission Specialist Marsha Ivins (center) with her launch and entry suit before she enters Atlantis for a simulated launch countdown. The White Room is an environmental chamber at the end of the orbiter access arm that mates with the orbiter to allow personnel to enter the orbiter’s crew compartment. The STS-98 crew is taking part in Terminal Countdown Demonstration Test activities, which also include emergency egress training at the pad. STS-98 is the seventh construction flight to the International Space Station, carrying as payload the U.S. Lab Destiny, a key element in the construction of the ISS. Launch of STS-98 is scheduled for Jan. 19 at 2:11 a.m. EST
