(04/25/2000) --- Waving to onlookers, the STS-101 crew eagerly walk to the waiting Astrovan that will take them to Launch Pad 39A and the second attempt at liftoff of Space Shuttle Atlantis. In their orange launch and entry suits, they are (left to right) Mission Specialists Susan J. Helms, Yury Usachev, James S. Voss, Mary Ellen Weber and Jeffrey N. Williams; Pilot Scott J. Horowitz; and Commander James D. Halsell Jr. The first launch attempt on April 24 was scrubbed due to unfavorable weather conditions. 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 will be the third assembly flight to the Space Station. Liftoff is targeted for 3:52 p.m. EDT. The mission is expected to last about 10 days, with Atlantis landing at KSC Saturday, May 6, about 11:53 a.m. EDT
