(04/26/2000) --- Smiling and waving to onlookers, the STS-101 crew eagerly walk to the waiting Astrovan that will take them to Launch Pad 39A a third time for launch of Space Shuttle Atlantis. From left are Mission Specialists Susan J. Helms, Yury Usachev of Russia, James S. Voss, Mary Ellen Weber and Jeffrey N. Williams; Pilot Scott J. Horowitz; and Commander James D. Halsell Jr. (pointing). The previous two launch attempts were scrubbed due to high cross winds at the Shuttle Landing Facility. 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
