STS-91 Mission Specialist Janet Lynn Kavandi gives a smile and a thumbs-up as two technicians help her with her flight suit in the Operations and Checkout (O&C) Building. The final fitting takes place prior to the crew walkout and transport to Launch Pad 39A. She is on her first Shuttle flight. Kavandi was selected as an astronaut candidate in 1994. She holds a doctorate in analytical chemistry and has received two patents. On this mission, she will be responsible for the SPACEHAB module aboard Discovery which will be used to transport supplies to Mir and bring back U.S. experiment hardware that has been in operation aboard the space station. She will also assist Chang-Diaz with AMS operations. STS-91 is scheduled to be launched on June 2 with a launch window opening around 6:10 p.m. EDT. The mission will feature the ninth and final Shuttle docking with the Russian space station Mir, the first Mir docking for Discovery, the first on-orbit test of the Alpha Magnetic Spectrometer (AMS), and the first flight of the new Space Shuttle super lightweight external tank. Astronaut Andrew S. W. Thomas will return to Earth as a STS-91 crew member after living more than four months aboard Mir
