STS-94 Pilot Susan L. Still prepares to enter the Space Shuttle Columbia at Launch Pad 39A in preparation for launch. She is the second woman to fly in this capacity on a Space Shuttle. Still is a lieutenant colonel in the Navy and has more than 2,000 flight hours in 30 different types of aircraft. She also holds a master’s degree in aerospace engineering. Still will assist Halsell with all phases of the space flight and will have primary responsibility to take action in the event of an emergency. After Columbia reaches orbit, Still will be busy with the many and varied tasks associated with monitoring and maintaining the orbiter. She and six fellow crew members will lift off during a launch window that opens at 1:50 p.m. EDT, July 1. The launch window will open 47 minutes early to improve the opportunity to lift off before Florida summer rain showers reach the space center
