'''Node 4''', also known as the '''Docking Hub System''' ('''DHS'''), was a proposed module of the [[International Space Station]] (ISS). In 2011 [[NASA]] was considering a 40-month design and development effort for Node 4 that would result in its launch in late 2013.<ref name=NasaSpaceflight>{{cite web|last=Bergin|first=Chris|title=Soyuz TMA-19 relocated as ISS managers discuss Node 4 addition|url=http://www.nasaspaceflight.com/2010/06/soyuz-tma-19-relocated-iss-discuss-node-4-addition/|work=NasaSpaceflight.com|accessdate=4 March 2011}}</ref>

 

In December 2011 [[Boeing]] proposed using Node 4 as the core of an [[Exploration Gateway Platform]] to be constructed at the [[ISS]] and relocated via [[space tug]] to an Earth-Moon [[Lagrange point]] (EML-1 or 2). The purpose of the platform would be to support lunar landing missions with a reusable [[Apollo Lunar Module|lunar lander]] after the first two [[Space Launch System|SLS]] flights. It would also satisfy the need for a L1 [[propellant depot]] for lunar missions. Other hardware would include an airlock, an 'international module', and a [[MPLM]] based habitat module.<ref>{{cite web|author=Chris Bergin |url=http://www.nasaspaceflight.com/2011/12/exploration-gateway-platform-hosting-reusable-lunar-lander-proposed/ |title=Exploration Gateway Platform hosting Reusable Lunar Lander proposed |publisher=NASASpaceFlight.com |date=2011-12-02 |accessdate=2013-11-22}}</ref>
