Since the Apollo Command Module (CM) and Soyuz spacecraft had incompatible docking and pressurization systems, the Docking Module was created to permit a link-up. One end of the DM could accommodate the probe and drogue docking system used during the Apollo lunar missions. The other end had a new six panel system for docking with Soyuz on this and possible future international flights. The DM also allowed for an atmospheric and pressure change from Apollo's 5 pounds per square inch (psi) pure oxygen atmosphere to Soyuz's 14.5 psi mixed gas atmosphere and vice-versa. The photograph shows the classroom environment during language instruction where Forostenko and other interpreters worked with the Apollo crew to familiarize them with Docking Module terminology using this blueprint. Includes a Typed Letter Signed by Forostenko. The blueprint is signed by tom stafford near the center.
