ISS Elements: Joint Airlock "Quest"
The Joint Airlock was launched on ISS-7A / STS-104 in July 2001 and was attached to the right hand docking port of Node 1. The Joint Airlock is 20 ft. long, 13 ft. in diameter, and weighs 6.5 tons. The Joint Airlock was built by Boeing at Marshall Space Flight Center. The Joint Airlock will be launched with the High Pressure Gas Assembly. The High Pressure Gas Assembly was mounted on the external surface of the Joint Airlock and will support EVAs operations with breathing gases and augments the Service Module's gas resupply system.
The crew airlock was derived from the Space Shuttle's external airlock. It is equipped with lighting, external handrails, and an Umbilical Interface Assembly (UIA). The UIA is located on one wall of the crew airlock and provides a water supply line, a wastewater return line, and an oxygen supply line. The UIA also provides communication gear and spacesuit power interfaces and can support two spacesuits simultaneously. This can be either two American EMU spacesuits, two Russian ORLAN spacesuits, or one of each design.
![]() The Equipment Airlock has stations that assist astronauts and cosmonauts as they get into and out of their spacesuits and to perform periodic maintenance. The Equipment airlock has two racks, one for avionics, the other for cabin air. Batteries, power tools and other supplies are also stored in the Equipment Airlock.
EVA Operations Documents
This document presents a description of EVAs for all ISS assembly, resupply, and utilization missions in tabular format.
"This plan identifies the procedures that will be followed by CTSD and contractor personnel to provide real-time support for Space Shuttle flights that involve scheduled, unscheduled or contingency EVA activities. Interfaces with other supporting contractors or organizations are given. Details involving mission support provided by these organizations must be obtained from the mission support plans, which they generate and publish."
