STS-78 Payload Commander Susan J. Helms gets a helping hand as she dons her launch/entry suit in the Operations and Checkout Building. On her third trip into space, Helms is serving as both payload commander and the flight engineer. Along with six fellow crew members, she will depart the O&C in a short while and head for Launch Pad 39B, where the Space Shuttle Columbia awaits liftoff during a two-and-a-half hour launch window opening at 10:49 a.m. EDT, June 20. STS-78 will be an extended duration flight during which extensive research will be conducted in the Life and Microgravity Spacelab (LMS) located in the payload bay.
