The STS-77 astronauts head for the Space Shuttle Endeavour at Launch Pad 39B and the final phase of the Terminal Countdown Demonstration Test (TCDT). Leading the way is Commander John H. Casper (front right) with Mission Specialist Mario Runco Jr. at left. Behind them are (from left) Pilot Curtis L. Brown Jr. and Mission Specialists Daniel W. Bursch, Marc Garneau (representing the Canadian Space Agency) and Andrew S. W. Thomas. The TCDT is held prior to each Space Shuttle flight and culminates with a mock launch countdown culminating in a simulated main engine cutoff scenario. During their stay at the space center, the flight crew also participates in training exercises at the pad and has the opportunity to view the payloads for their upcoming spaceflight. Endeavour currently is targeted for liftoff around May 16. (Photo Release Date: 04/23/96 )
