Abstract:
1. A docking interface mechanism for spacecraft comprising: a frame; at least one alignment pin extending outward from the frame, the at least one alignment pin comprising: wherein the at least one alignment pin is configured for insertion within a corresponding alignment cup of another docking interface mechanism when the shape memory alloy coupling is below an associated austenitic temperature of the shape memory alloy, wherein the at least one alignment pin is further configured to form a rigid mechanical connection with an alignment cup pipe in the corresponding alignment cup when the temperature of the shape memory alloy coupling increases to an associated austenitic temperature of the shape metal alloy, wherein the at least one alignment pin is further configured to release the rigid mechanical connection when the temperature of the shape memory alloy coupling decreases to an associated martensitic temperature of the shape metal alloy; and at least one alignment cup set in the frame, the at least one alignment cup configured to receive a corresponding alignment pin, the at least one alignment cup including an alignment cup pipe.
