===Pressurised modules===
When completed in late 2011, the ISS will consist of sixteen pressurised modules with a combined volume of around {{convert|1000|m3}}.{{Citation needed|date=March 2011}} These modules include laboratories, docking compartments, airlocks, nodes and living quarters. Fifteen of these components are already in orbit, with the remaining two awaiting launch. Each module was or will be launched either by the Space Shuttle, Proton rocket or [[Soyuz (rocket family)|Soyuz rocket]].<ref name="ESA sequence">{{cite web|url=http://esamultimedia.esa.int/multimedia/esa_iss_assembly_sequence/index_pop.html|publisher=European Space Agency (ESA)|accessdate=6 March 2009|title=HSF: ISS assembly sequence and on-orbit configuration}}</ref>
