The "Bigelow Next-Generation Commercial Space Station" is a private orbital space complex currently under development by Bigelow. The space station will include both "Sundancer" and B330 expandable spacecraft modules and a central docking node, propulsion, solar arrays, and attached crew capsules. Initial launch of space station components was planned for 2014, with portions of the station available for leased use as early as 2015. Bigelow has publicly shown space station design configurations with up to nine B330 modules containing of habitable space. Bigelow began to publicly refer to the initial configuration — two Sundancer modules and one B330 module — of the first Bigelow station as "Space Complex Alpha" in October 2010.
