(04/26/2000) --- In the Operations and Checkout Building, STS-101 Mission Specialist Mary Ellen Weber waves as she is helped with her launch and entry suit before heading a third time to Launch Pad 39A and launch of Space Shuttle Atlantis. 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
