<P> The Bigelow Next - Generation Commercial Space Station is a private orbital space station currently under development by Bigelow Aerospace . The space station may be constructed of two B330 expandable spacecraft modules as well as a central docking node, propulsion, solar arrays, and attached crew capsules, though other possibilities like attaching a B330 to the International Space Station or flying a B330 alone have been suggested by Robert Bigelow . </P> <P> On 8 April 2016, NASA launched a Bigelow inflatable module and attached it to the ISS, where it will be tested for two years . Any independent Bigelow Commercial space station will have to await the development of commercially available human rated orbital spacecraft . The first of these is expected to be the SpaceX Dragon 2 in 2018 . Two B330 are expected to be ready by 2020 and a launch contract for one in 2020 has been signed . </P>

When will the next space station be built
