NASA has signed a $17.8 million contract with Bigelow Aerospace for a new ISS module.
Update: See new details here.
The Bigelow Expandable Activity Module (BEAM) could be delivered to the International Space Station within 24 months by a SpaceX Falcon 9 or Orbital Sciences Antares rocket. BEAM would provide ISS astronauts with extra storage space while providing data on the performance of inflatable modules in the space environment.
Bigelow has been doing unfunded studies for several years. These pictures are from a NASA presentation back in 2010.
