AS-202, the second Saturn IB launch vehicle developed by the Marshall Space Flight Center, lifts off from Cape Canaveral, Florida, August 25, 1966. Primary mission objectives included the confirmation of projected launch loads, demonstration of spacecraft component separation, and verification of heat shield adequacy at high reentry rates. In all, nine Saturn IB flights were made, ending with the Apollo-Soyuz Test Project (ASTP) in July 1975.
