(04/26/2000) --- The STS-101 crew wave to onlookers as they leave the Operations and Checkout Building enroute a third time to Launch Pad 39A for launch of Space Shuttle Atlantis. The previous two launch attempts were scrubbed due to high cross winds at the Shuttle Landing Facility. They are (front) Pilot Scott J. Horowitz (left) and Commander James D. Halsell Jr.; (middle) Mission Specialists Mary Ellen Weber and Jeffrey N. Williams; (back) Mission Specialists Susan J. Helms, Yury Usachev of Russia and James S. Voss. The mission will take the crew to the International Space Station to deliver logistics and supplies and to prepare the Station for the arrival of the Zvezda Service Module, expected to be launched by Russia in July 2000. Also, the crew will conduct one space walk. This is the third assembly flight to the Space Station. After the 10-day mission, Atlantis is expected to land at KSC May 6 at about 12:03 p.m. EDT
