BODY SEAL CLOSURE

The Body Seal Closure (BSC) provides an interface between the Lower Torso Assembly (LTA) and the Hard Upper Torso (HUT) of the Extravehicular Mobility Unit (EMU) spacesuit.

The BSC also incorporates two protruding bosses, allowing attachment of the mini work station which serves as a surface and tool holder for astronauts during extravehicluar activities.

SCU AND DCM MULTIPLE CONNECTORS

The Service and Cooling Umbilical (SCU) and the Display and Control Module (DCM) multiple connectors are critical life support connectors for the EMU. The SCU and DCM connectors provide astronauts with oxygen, potable water and cooling water. The units are capable of providing 730 psi oxygen @ 4.8 lbs/hr, 15 psi potable water @ 1 lb/min, and 20 psi cooling water @ 4 lbs/hr. The SCU and DCM connectors are capable of mating and demating in either the pressurized or unpressurized state without leakage.
