NASA completes tool tests for orbital refueling project

Since then, the project has concentrated on the tools used in transfers. Specifically, the Cryogen Servicing Tool that connects the source tank and receiver tank, the Multi-Function Tool 2 (MFT2) to operate the cryogenic transfer adapters, and the Visual Inspection Poseable Invertebrate Robot 2 (VIPIR2) for verifying the proper cryogen transfer between tanks. For this, Dextre undertook the task of unstowing the cryogen coupler adapter using MFT2 and inserted it into the cryogen coupler adapter port. The RRM3 module then took over the remainder of the refueling tasks.
