KENNEDY SPACE CENTER, Fla. -- Space Shuttle Discovery prepares to land at the KSC Shuttle Landing Facility on runway 15. Main gear touchdown occurred about 2:31:42 a.m. EST, nose wheel touchdown at 2:31:54 a.m., and wheel stop at 2:33:06 a.m. The landing, on orbit 201, concluded mission STS-102, the eighth flight to the International Space Station, carrying the first Multi-Purpose Logistics Module Leonardo, to the ISS and Expedition Two, a replacement crew for the Station. The 12-day, 19-hour, 51-minute mission returned both the Leonardo and the first resident crew of the ISS, Expedition One, to KSC. Discovery logged 5.3 million miles on this mission. The landing marked the 54th at KSC in the history of the program, and the 12th night landing at KSC
