ISS Quest Joint Airlock

Previously known as the Joint Airlock Module, is the primary airlock for the International Space Station. Quest was designed to host spacewalks with both Extravehicular Mobility Unit (EMU) spacesuits and Orlan space suits. Before Quest was attached, Russian spacewalks using Orlan suits could only be done from the Zvezda service module and American spacewalks using EMUs were only possible when a Space Shuttle was docked.
