The Quest Airlock is a pressurized space station module consisting of two compartments attached end-to-end by a connecting bulkhead and hatch. The two compartments are the Equipment Lock which provides the systems for suit maintenance and refurbishment and the Crew Lock which provides the actual exit for performing spacewalks. The airlock is the primary path for spacewalk entry and departure for astronauts wearing U.S. spacesuits. Quest can also support the Russian Orlan spacesuit for spacewalks.
