Joint Airlock Quest
<ul><li>NASA/Boeing</li>
<li>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 consist of: the Equipment Lock, which provides the systems and volume for suit maintenance and refurbishment, and the Crew Lock, which provides the actual exit for performing EVAs. The airlock is the primary path for International Space Station spacewalk entry and departure for U.S. spacesuits, which are known as Extravehicular Mobility Units, or EMUs. Quest can also support the Russian Orlan spacesuit for spacewalks.</li></ul>
