International Space Station
The International Space Station (ISS) is the largest artificial body in orbit, it can often be seen with the naked eye from Earth. The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars.
Fluid Quick Disconnect Coupling (FQDC)
The FQDC are used on the International Space Station (ISS) Electrical Power System. The coupling provides the interconnection of fluid lines from the Active Half to the Passive Half at the interface of these separate components. When interconnected, the Active Half and Passive Half fluid lines allow for low pressure drop fluid flow through these components. When detached, the Passive Half and the Active Half provide a positive leak tight seal against fluid flow.
NASA Docking System (NDS), Soft Capture System (SCS)
This SCS is a Six Degree of Freedom (6DOF) motion control platform consisting of an electronic controller and six electromechanical actuators. The control system is designed to help the Commercial Crew Vehicles dock autonomously to the International Space Station (ISS) by extending the capture ring to the ISS. The system senses the initial contact at any point on the ring and then continues contacting the rest of the ring until complete contact where latching commensurates. Following the latching of the Crew Vehicle ring to the ISS ring, the capture system fully retracts bring the Crew Vehicle to the ISS where docking can be completed.
