At the slidewire landing area of Launch Pad 39A at NASA's Kennedy Space Center, the STS-124 crew poses for a final group photo following the media question-and-answer event. From left are Commander Mark Kelly, Pilot Ken Ham, and Mission Specialists Karen Nyberg, Ron Garan, Mike Fossum, Akihiko Hoshide and Greg Chamitoff. Hoshide represents the Japan Aerospace Exploration Agency. In the background is the fixed service structure (center) and the 300-gallon water tower (left). The crew is at Kennedy for a dress launch rehearsal called the terminal countdown demonstration test. TCDT provides astronauts and ground crews with an opportunity to participate in various simulated countdown activities, including equipment familiarization and emergency training. On the STS-124 mission, the crew will deliver and install the Japanese Experiment Module – Pressurized Module and Japanese Remote Manipulator System. Discovery's launch is targeted for May 31.
