The STS-100 crew poses for a photo after landing at the Shuttle Landing Facility. They are at KSC to take part in Terminal Countdown Demonstration Test activities, from emergency escape training at the pad to a simulated launch countdown. Standing, left to right, are Mission Specialists Yuri Lonchakov, John Phillips, Umberto Guidoni; Pilot Jeff Ashby; Mission Specialists Chris Hadfield and Scott Parazynski; and Commander Kent Rominger. 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
