particularly beneficial for lunar astronauts or the crews of other long-duration space missions, which until now have been restricted to fairly cramped quarters for the several-day flight. Technology While details on the purchased TransHab technology have not been published, NASA states the following about the structure of the module that Bigelow adopted as a starting point: Bigelow has described their technology to news media and have indicated that their proprietary technology inflatable shell, now in validation test in low-Earth orbit in two subscale spacecraft, incorporates a layer of Vectran, along with the Kevlar, etc. of the NASA technology. History Its design is based on the cancelled NASA TransHab program. Bigelow gained access to TransHab engineers and workers, some of whom later went on to advise Bigelow's project. The module follows the launch of two demonstration modules successfully tested in Earth orbit, Genesis I in 2006 and Genesis II in 2007. , Bigelow Aerospace had plans to develop the CSS Skywalker, a space station based upon using B330 modules to act as an orbital hotel. Plans in 2010 continued to call for construction of a space station, but without the CSS Skywalker moniker, with "more usable volume than the existing International Space Station". Those plans included a complex of two smaller Sundancer modules, a combined node and propulsion module and one full-size B330 in order to provide a total volume that was only somewhat less than that of the International Space Station, though built from fewer and larger individual modules. In early 2010, Bigelow selected Orbitec as the supplier for environmental control and life support systems (ECLSS). , an initial launch of the B330 was slated to be no earlier than 2015, following a notional launch of the smaller Sundancer habitat in 2014. In July 2010, Bigelow announced that a B330 would be the sixth spacecraft component making up the notional Bigelow Commercial Space Station. The Sundancer development was later halted, with a decision to move directly from the Genesis-series prototypes to the B330. , Bigelow Aerospace indicated that the company has the financial capacity to produce at least two B330 habitats, along with a couple of transit tugs and a docking node if Bigelow is able to secure commercial customers to pay for approximately half of the launch costs for these systems. In February 2014, some pricing and other lease details were made public. The B330 lease rate will be
