The Bigelow Aerospace project to privately develop inflatable Earth-orbit space modules is beginning to integrate diverse U.S. and European technologies into subscale and full-scale inflatable test modules and subsystems at the company’s heavily guarded facilities here. While much public attention is focused on the massive International Space Station (ISS), Bigelow has quietly become a mini-Skunk Works for the NASA Johnson Space Center (JSC). Ongoing technical assistance to Bigelow from JSC is focused on helping the company spawn development of orbiting commercial inflatable modules by the end of the decade, with the possibility of JSC later using the Bigelow technology for inflatable modules on the Moon or Mars.
