STS-100 Mission Specialist Chris Hadfield arrives for Terminal Countdown Demonstration Test activities.

STS-100 Mission Specialist Chris Hadfield arrives at KSC for Terminal Countdown Demonstration Test activities. He and the rest of the crew Commander Kent V. Rominger, Pilot Jeffrey S. Ashby and Mission Specialists Scott E. Parazynski, John L. Phillips, Umberto Guidoni and Yuri Lonchakov are going to be taking part in emergency escape training at the pad, equipment familiarization and a simulated launch countdown. An international crew, Hadfield is with the Canadian Space Agency, Guidoni the European Space Agency and Lonchakov the Russian Aviation and Space Agency. The mission is carrying the Multi-Purpose Logistics Module Raffaello and the Canadian robotic arm, SSRMS, to the International Space Station. Raffaello carries six system racks and two storage racks for the U.S. Lab. The SSRMS is crucial to the continued assembly of the orbiting complex and has a unique ability to switch ends as it works, “inchworming” along the Station’s exterior. Launch of mission STS-100 is scheduled for April 19 at 2:41 p.m. EDT from Launch Pad 39A
