Astronaut Donald K. Slayton helps check out the Docking Module backup flight article during Apollo-Soyuz Test Project preflight preparations at the Johnson Space Center. Slayton, docking module pilot of the American ASTP crew, participates in a DM thermo-vacuum test walk-through "dry run" in Chamber B, Space Environment Simulation Laboratory, Building 32, at the Johnson Space Center. The joint U.S.-USSR ASTP mission is scheduled for the summer of 1975. The DM is designed to link the Apollo and Soyuz spacecraft when they dock in Earth orbit. The DM is manufactured by the U.S. and will be launched with the Apollo spacecraft.
