KENNEDY SPACE CENTER, FLA. - In the White Room on Launch Pad 39B, STS-114 Mission Specialist Wendy Lawrence makes a final adjustment on her launch suit before entering the hatch on Space Shuttle Discovery, behind her. The crew is taking part in a full dress rehearsal for launch, including countdown and culminating in main engine cutoff. The rehearsal is the final part of Terminal Countdown Demonstration Test (TCDT) activities that the crew has been involved in for three days. TCDT provides the crew of each mission an opportunity to participate in various simulated countdown activities, including equipment familiarization and emergency egress training. STS-114 is the first Return to Flight mission to the International Space Station. The launch window extends July 13 through July 31.
