The Quest Airlock is in the process of being installed onto the starboard side of the Unity Node 1 of the International Space Station (ISS). Astronaut Susan J. Helms, Expedition Two flight engineer, used controls onboard the station to maneuver the Airlock into place with the Canadarm2, or Space Station Remote Manipulator System (SSRMS). The Joint Airlock is a pressurized flight element consisting of two cylindrical chambers attached end-to-end by a cornecting bulkhead and hatch. Once installed and activated, the ISS Airlock becomes the primary path for ISS space walk entry and departure for U.S. spacesuits, which are known as Extravehicular Mobility Units (EMUs). In addition, it is designed to support the Russian Orlan spacesuit for extravehicular activity (EVA). The Joint Airlock is 20-feet long, 13-feet in diameter and weighs 6.5 tons. It was built at the Marshall Space Flight Center (MSFC) by the Space Station prime contractor Boeing. The ISS Airlock has two main components: a crew airlock and an equipment airlock for storing EVA and EVA preflight preps. The Airlock was launched on July 21, 2001 aboard the Space Shuttle Orbiter Atlantis for the STS-104 mission.

This artist's concept is a cutaway illustration of the Skylab Airlock Module and its characteristics. The aft end of the Docking Adapter mated to the Airlock Module (AM), and served as the environmental, electrical, and communications control center. The docking adapter also contained the port through which the astronauts exited to perform extravehicular activity. The AM contained a turnel section through which Skylab crewmen could move between the workshop and the forward end of the airlock. It was encircled, for part of its length, at its aft end by the fixed Airlock Shroud (FAS), that had the same diameter as the workshop (22 feet) and was attached to the workshop's forward end. High pressure containers for oxygen and nitrogen providing Skylab's atmosphere, were mounted in the annular space between the outside of the tunnel and the inside of the shroud. The forward end of the FAS was the base on which the tubular structure supporting the solar observatory was mounted. Many of the supplies, and most of the control systems for Skylab were located in the AM; this module could well be the "utility center" of the Skylab cluster. McDonnell Douglas fabricated the module with close Marshall Space Flight Center's involvement in design, development, and test activities.

This is a close-up photograph of the Orbital Workshop (OWS) trash disposal airlock located on the floor of the lower level of the OWS. It provided a means of passing trash from the pressurized habitable area into the unpressurized waste tank. The crewman opened a valve which brought the airlock to the same pressure as that within the workshop. He then opened the lid, placed the bagged trash inside, closed the lid and locked it. By turning the valve handle, he reduced the pressure within the airlock until it reached the vacuum of the waste tank. The crewman then operated an ejector handle that caused a scissors-type mechanism to push the bagged trash from the airlock into the tank.

This photograph depicts the flight article of the Airlock Module (AM) Flight Article being mated to the Fixed Airlock Shroud and aligned in a clean room of the McDornell Douglas Plant in St. Louis, Missouri. The AM enabled crew members to conduct extravehicular activities outside Skylab as required for experiment support. Separated from the Workshop and the Multiple Docking Adapter by doors, the AM could be evacuated for egress or ingress of a space-suited astronaut through a side hatch. Oxygen and nitrogen storage tanks needed for Skylab's life support system were mounted on the external truss work of the AM. Major components in the AM included Skylab's electric power control and distribution station, environmental control system, communication system, and data handling and recording systems. The Marshall Space Flight Center was responsible for the design and development of the Skylab hardware and experiment management.

The Quest Airlock makes it easier to perform space walks, and allows both Russian and American spacesuits to be worn when the Shuttle is not docked with the International Space Station (ISS). American suits will not fit through Russion airlocks at the Station. The Boeing Company, the space station prime contractor, built the 6.5-ton (5.8 metric ton) airlock and several other key components at the Marshall Space Flight Center (MSFC), in the same building where the Saturn V rocket was built. Installation activities were supported by the development team from the Payload Operations Control Center (POCC) located at the MSFC and the Mission Control Center at NASA's Johnson Space Flight Center in Houston, Texas.

KENNEDY SPACE CENTER, FLA. -- In the Space Station Processing Facility at NASA's Kennedy Space Center, members of the STS-124 crew look over the scientific airlock in the Kibo pressurized module. The module is part of the payload for the mission, targeted for launch no earlier than April 24. The crew comprises seven: Commander Mark Kelly, Pilot Kenneth Ham, and Mission Specialists Karen Nyberg, Ronald Garan, Michael Fossum and Akihiko Hoshide. The crew is at Kennedy for a crew equipment interface test that includes familiarization with tools and equipment that will be used on the mission. The STS-124 mission is the second of three flights that will launch components to complete the Japanese pressurized module, the Kibo laboratory. The mission will include two spacewalks to install the new lab and its remote manipulator system. The lab's logistics module, which will have been installed in a temporary location during STS-123, will be attached to the new lab. Photo credit: NASA/Kim Shiflett
