Get a grip

This February 21 image from the ISS shows the NanoRacks Bishop airlock attached to Canadarm2’s robotic hand-like attachment (or in industry speak, the latching end effector). The airlock can be uninstalled from its regular location on the Tranquility module for portable operations, and also for stowing cargo or extracting payloads. The ISS was above the Atlantic Ocean when this beautiful image was captured.
