(11/16/1998) -- NASA's 'Super Guppy' aircraft rolls to a stop at the KSC Shuttle Landing Facility after leaving Marshall Space Flight Center in Huntsville, Ala. The gargantuan plane carries the U.S. Laboratory module, considered the centerpiece of the International Space Station. The module will undergo final pre-launch preparations at KSC's Space Station Processing Facility. Scheduled for launch aboard the Shuttle Endeavour on mission STS-98, the laboratory comprises three cylindrical sections with two end cones. Each end-cone contains a hatch opening for entering and exiting the lab. The lab will provide a shirtsleeve environment for research in such areas as life science, microgravity science, Earth science and space science. Designated Flight 5A, this mission is targeted for launch in early 2000
