Tranquility (ISS Module)

Tranquility (ISS Module)

Tranquility, also known as Node 3, is a module of the International Space Station (ISS). ESA and the Italian Space Agency had Tranquility built by Thales Alenia Space. A ceremony on November 20, 2009 transferred ownership of the module to NASA. On February 8, 2010, NASA launched the module on the Space Shuttle's STS-130 mission.

The module provides six berthing locations, however three of those locations are disabled as modules originally planned to be attached to Tranquility were canceled. STS-130 also brought the Cupola, a large window module and robotics work station to the ISS which will be attached to the nadir-side of Tranquility. The module also includes various ISS systems, including additional life support systems.
