Tranquility Module

Quick Facts

Key portions of the International Space Station are pictured from a window on the Nauka Multipurpose Laboratory Module. From left to right are, the Kibo laboratory module, the Japanese robotic arm, the Permanent Multipurpose Module, the Tranquility module, the cupola, and the Bigelow Expandable Activity Module (BEAM).
The Tranquility module hosts four major station elements including BEAM, the cupola, the Permanent Multipurpose Module, and the NanoRacks Bishop airlock.

Tranquility provides additional room for crew members and many of the space station’s life support and environmental control systems. These systems include air revitalization, oxygen generation and water recycling. A waste and hygiene compartment and a treadmill also are located there. Tranquility is connected to the port side of the Unity node and can provide additional docking points for vehicles. Tranquility was built for NASA by Thales Alenia Space in Turin, Italy, under contract to ESA.
