STS-98 Pilot Mark Polansky is pleased to arrive at KSC’s Shuttle Landing Facility for Terminal Countdown Test Activities. In preparation for the Jan. 19 launch, he and the rest of the crew Commander Ken Cockrell and Mission Specialists Robert Curbeam, Thomas Jones and Marsha Ivins will be training in emergency procedures from the pad, checking the payload and taking part in a simulated countdown. The payload for the mission is the U.S. Lab Destiny, a key element in the construction of the International Space Station. The lab has five system racks already installed inside the module. After delivery of electronics in the lab, electrically powered attitude control for Control Moment Gyroscopes will be activated. STS-98 is the seventh construction flight to the ISS.<br KSC01pp0022

The Space Shuttle program was the United States government's manned launch vehicle program from 1981 to 2011, administered by NASA and officially beginning in 1972. The Space Shuttle system—composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank— carried up to eight astronauts and up to 50,000 lb (23,000 kg) of payload into low Earth orbit (LEO). When its mission was complete, the orbiter would re-enter the Earth's atmosphere and lands as a glider. Although the concept had been explored since the late 1960s, the program formally commenced in 1972 and was the focus of NASA's manned operations after the final Apollo and Skylab flights in the mid-1970s. It started with the launch of the first shuttle Columbia on April 12, 1981, on STS-1. and finished with its last mission, STS-135 flown by Atlantis, in July 2011.
