Stock Photo - This artist´s concept shows the International Space Station when its assembly sequence is completed in 2004, including minor changes to the final station configuration agreed upon by international partners in May 1998. This view shows the third connecting module, or node, attached to the station. On the left of the node is the X_38 crew return vehicle. On the right is the U.S. Habitation module. Behind the third node in this view is a Russian docking and stowage module that has been expanded in size, while the overall number of Russian modules was reduced by one. The 1_million pound station will have a pressurized volume equal to two jumbo jets and an acre of solar panels.
