July 1, 1997, 2:02:00 p.m. EDT. Liftoff was delayed about 12 minutes because of unacceptable weather conditions in the launch area in the event a return-to-launch-site abort was necessary.
The launch window originally was targeted to open at 2:37 p.m., July 1. On June 30, NASA managers decided to move it back 47 minutes to 1:50 p.m. to avoid forecasted afternoon thundershowers.
