S81-36331 (24 Aug. 1981) --- Astronauts Joe H. Engle, left, and Richard H. Truly pause before participating in the integrated test of the assembled space shuttle components scheduled for launch no earlier than Sept. 30, 1981. Moments later, Engle, STS-2 crew commander, and Truly, pilot, entered the cabin of the orbiter Columbia for a mission simulation. The shuttle integrated tests (SIT) are designed to check out every connection and signal path in the STS-2 vehicle composed of the orbiter, two solid rocket boosters (SRB) and an external fuel tank (ET) for Columbia?s main engines. Completion of the tests will clear the way for preparations for rollout to Pad A at Launch Complex 39, scheduled for the latter part of August or early September. Photo credit: NASA
