DOCKING MODULE BLUEPRINTSIGNED.
"Modification Decals, DM Russian Nomenclature." Large blueprint, 21 by 85 inches folded to 8 by 11 inches, illustrating the Docking Module (DM) and Command Module hatches, intercom system, pressurization modification and related gauges, and a locator diagram of the DM systems. All components labeled in English and Russian. Together with a color photograph, 8 by 10 inches, showing an ASTP training session with the present blueprint in use.
Provenance: From the collection of Anatole Forostenko, chief Russian language instructor for the ASTP astronauts.
SIGNED BY TOM STAFFORD near the center. Since the Apollo Command Module and the Soyuz spacecraft had incompatible docking and pressurization systems, the DM was created to allow them to link up. The photograph shows the classroom during language instruction where Forostenko and other interpreters worked with the Apollo crew to familiarize them with DM terminology using this blueprint.
