Abstract: Material transfer interfaces for space vehicles, and associated systems and methods are disclosed. A representative system includes a first coupler configured to be carried by a first space vehicle, and a first valve device carried by the first coupler. The system further includes a second coupler configured to be carried by a second space vehicle and a second valve device carried by the second coupler. The first coupler includes rotatable and translatable latch arms positioned to engage with and connect to the second coupler. The first valve device incudes a moveable probe that is insertable into the second valve device when the latch arms of the first coupler are connected to the second coupler to transfer fluid between the first and second valve devices.

Abstract: Material transfer interfaces for space vehicles, and associated systems and methods, are disclosed. A representative system includes a coupling mechanism including a support structure, a latch-arm base movably connected to the support structure, and a latch arm pivotably connected to the latch-arm base. Another representative system includes a service valve portion, a coupling portion configured to receive the service valve portion, and a coupling mechanism for coupling the service valve portion to the coupling portion. The coupling mechanism can include latch arms positioned to pivot between a position in which the latch arms are pivoted outwardly and a position in which the latch arms are pivoted inwardly to capture the service valve portion. The latch arm can be carried by a latch-arm base that translates relative to a support structure of the coupling portion. Material transfer interfaces can include self-aligning ports having faces that engage each other with cup-and-cone structures.
