Mission overview

With the flight of Soyuz 16, the entire program of the ASTP Soviet side was simulated. It focused in particular on the testing of the androgynous coupling system and the change in the cabin atmosphere. The Apollo atmosphere was pure oxygen. When a Soyuz normal atmosphere (nitrogen / oxygen) was used. In order not to make too long at the planned Umstiegen the lock stays for blood matching, the oxygen content of the cabin pressure of 760 mm was in Soyuz increased and decreased to 540 mm of mercury. For the newly developed coupling unit hydraulic couplings were simulated with an entrained counterpart performed ( 32 and 38 mission in orbit ).
