The Pressurized Mating Adapter 1 (PMA-1) connects the US Orbital Segment (USOS) and the Russian Segment (RS) between modules NOD1 and FGB. Both modules use different connector systems: Unity uses the USOS-standard CBM, while Zarja uses APAS-89 - one of the russian docking ports.
In addition to providing a pressurized connection, PMA-1 also providing storage space for soft containers along the inner walls, data and power connections, and provides an integrated air heater unit.
