ISS node 3
From Wikipedia, the free encyclopedia
Node 3 is an element scheduled to be added to the International Space Station in 2009 or 2010 and will contain the most advanced life support systems ever flown in space. These systems will recycle waste water for crew use and generate oxygen for the crew to breathe. In addition, Node 3 will contain an atmosphere revitalization system to remove contaminants from the atmosphere and monitor/control the atmosphere constituents of the ISS. Node 3 will also contain a Waste and Hygiene Compartment (toilet) for supporting the on-board crew.
Node 3 is also designed to provide berthing locations with power, data and commanding, thermal and environmental control, and crew access for more attached habitable volumes or for crew transportation vehicles or stowage, or an appropriate combination of all of these.
Node 3 will also have a Cupola attached to it with a Robotic Work Station inside it to assist in the assembly/maintenance of the ISS as well as offer a window for earth observations. Node 3 will be launched with the Cupola attached to the nadir, or earthward facing port. After mating with the nadir port of Unity, the Cupola will be moved to the front port. Node 3 will also have redundant ports for the logistics module or the Space Shuttle to be berthed.
[edit] Current status
Some sources reported that Node 3 was cancelled, but an ISS manifest released on February 25, 2006 has the last Shuttle flight carrying Node 3 and the Cupola to orbit in 2009.
