History

Early work at Bigelow Aerospace on expandable space habitats, with plans to eventually assemble them into on-orbit space stations, began in the early years after the company was formed in 1999. By 2004, plans made public included assembly of multiple modules "into a manned space facility in

'' The Space Review'', 19 July 2004, accessed 16 July 2010. Two more formal concepts have since been made public. By 2005, Bigelow space station plans had been further conceptualized into ''Commercial Space Station Skywalker'', or CSS Skywalker. In mid-2010, Bigelow announced their ''Next-Generation Commercial Space Station''—later named "Space Complex Alpha". The initial dates for the Alpha complex were not achieved. In January 2013, the Alpha complex was specified to be an in-space assemblage of only two B330 modules, with the first module to be launched no earlier than 2016.

CSS Skywalker

The CSS Skywalker (Commercial Space Station Skywalker) was a 2005 concept for the first "space hotel" by Bigelow Aerospace.The Five-Billion-Star Hotel, 1 March 2005

". Encyclopedia Astronautica, accessed 16 July 2010. In short, CSS Skywalker was "an effort to build the planet's first orbiting space hotel, ith a projectedroom rate of USD$1 million per night", and a hoped-for launch date for the first Nautilus module of 2010.

Company challenges

Early assessments of the probability of success of the technology development and challenges of a commercial space station pointed to the importance of factors largely beyond Bigelow's control. For example, in 2005, John M. Logsdon, director of

With the initial Space Complex Alpha, Bigelow "would need six flights a year; with the launch of a second, larger station, that number would grow to 24, or two a month." After 2010, no further concrete plans have been announced for transport with Atlas V launch vehicles. In May 2012, almost simultaneously with the successful mission of SpaceX's Dragon capsule, launched by SpaceX's Falcon 9 vehicle, to the International Space Station, Bigelow and SpaceX jointly announced that they were teaming to offer private crewed missions to space, promoting the Bigelow space station and SpaceX transport systems.

If the entire station is leased out, it could mean up to 25 Launches per year for crew and cargo. In early 2013, Bigelow Aerospace started referring to Alpha as consisting of two B330 modules instead of two Sundancer and one B330. In October 2010, Bigelow announced that it has memorandum of understanding with six sovereign nations to utilize the on-orbit facilities of the commercial space station:

The initial plan was to test the expandable habitat technology for at least two years. During its flight mission, NASA has been testing and monitoring the module's structural integrity, leak rate, radiation dosage and temperature changes. The module has been performing well, and in October 2017, it was announced that the module would stay attached to the ISS until 2020, with options for two further one-year extensions. The module is being used to store up to 130 cargo transfer bags in an effort to free up additional space aboard the station.
