However it now appears that each B330 can operate as an independent space station. Attaching a B330 to the [[International Space Station]] or flying a B330 alone have been suggested by Robert Bigelow. On 8 April 2016, NASA launched a [[Bigelow Expandable Activity Module|Bigelow inflatable module]]<nowiki> and attached it to the ISS, where it has been tested for over four years. Two B330s are expected to be ready by 2020 and a launch contract for one in 2021 followed by move to low lunar orbit in 2022 has been signed.{{</nowiki>[[Template:Citation needed|Citation needed]]<nowiki>}}</nowiki> ==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 [[low Earth orbit]] for both {{Sic|hide=y|privately|-}} and {{Sic|hide=y|publicly|-}}funded research and for [[space tourism]]."<ref name="sr20040719">[http://www.thespacereview.com/article/187/1 Inflatable privately owned orbital facilities], ''[[The Space Review]]'', 19 July 2004, accessed 16 July 2010.</ref> 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.<ref name="ps20050301" /> In mid-2010, Bigelow announced their ''Next-Generation Commercial Space Station''—later named "Space Complex Alpha".<ref name="tsr20101101" /><ref name="baocc20100715" /> 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.<ref name="nsw20130117">{{cite news |last=Lindsey |first=Clark |title=More on the Bigelow module for the ISS and on the Bigelow station |url=http://www.newspacewatch.com/articles/more-on-the-bigelow-module-for-the-iss-and-on-the-bigelow-station.html |access-date=18 January 2013 |newspaper=NewSpace Watch |date=17 January 2013}}</ref> ===CSS Skywalker=== {{Infobox space station | station = CSS Skywalker | crew = 5–7 | mass = {{convert|100000|kg|abbr=on}}<ref name="ea20100706" /> | height = {{convert|30.0|m|abbr=on}}<ref name="ea20100706" /> | diameter = {{convert|6.7|m|abbr=on}}<ref name="ea20100706" /> | volume = {{convert|1500|m3|abbr=on}}<ref name="ea20100706" /> }} The '''CSS Skywalker''' ('''Commercial Space Station Skywalker''') was a 2005 concept for the first "space hotel" by Bigelow Aerospace.<ref name="ps20050301">[http://www.popsci.com/scitech/article/2005-03/five-billion-star-hotel The Five-Billion-Star Hotel, 1 March 2005]</ref> The Skywalker was designed to be composed of multiple Nautilus (B330) habitat modules, which would be inflated and connected upon reaching orbit.

For example, in 2005, John M. Logsdon, director of [[George Washington University]]'s Space Policy Institute said "I have little doubt that the basic technology is likely to work ... The issue is whether there's a [[space transport|transportation]] system that can get people or things, or both, up there."<ref name="ps20050301" /> In practice, orbital launch plans were significantly delayed. First, after the [[Space Shuttle Columbia disaster|Space Shuttle ''Columbia'' disaster]] in 2003, Bigelow had to compete with [[NASA]] for rides on the [[Russia]]n [[Soyuz (spacecraft)|Soyuz]] three-person rocket — "a distinctly untenable position."<ref name="ps20050301" /><ref name="sdc200041108">{{cite news |url=http://www.space.com/spacenews/businessmonday_bigelow_041108.html |title=Exclusive: Rules Set for $50 Million 'America's Space Prize' |author=Leonard David |publisher=Space News |date=8 November 2004 |access-date=6 August 2011 |archive-url=https://web.archive.org/web/20090629193043/http://www.space.com/spacenews/businessmonday_bigelow_041108.html |archive-date=29 June 2009 |url-status=live}}</ref> In mid-2009, Bigelow announced they were continuing to develop a variety of space habitat architectures.<ref name="ps20090814">[http://www.popsci.com/military-aviation-amp-space/article/2009-08/space-hotel-visionary-proposes-modified-spaceship-nasa Space Hotel Visionary Proposes Modified "Orion Lite" Spaceship for NASA, 14 August 2009]</ref> ===Space transport=== In 2008, Bigelow initially began talks with [[Lockheed Martin]] to potentially contract launch services on its [[Atlas V]]-401 vehicle for both crew and cargo launches.<ref name="ba20080205">{{cite press release |title=Bigelow Aerospace and Lockheed Martin Converging on Terms for Launch Services |publisher=Bigelow Aerospace |date=5 February 2008 |url=http://www.bigelowaerospace.com/news |access-date=9 March 2008 }}</ref><ref name="ns20080207">[https://www.newscientist.com/article/dn13290-no-major-hurdles-to-upgrade-atlas-v-rockets-for-people.html No major hurdles to upgrade Atlas V rockets for people], David Shiga, ''[https://www.newscientist.com NewScientist.com]'', 7 February 2008, accessed 20 July 2010</ref> By mid-2010, Bigelow was actively pursuing launch options for its space station modules and crew capsules from two launch systems: the [[Boeing]] [[CST-100]] capsule on a [[United Launch Alliance|ULA]] [[Atlas V]] launcher and also the [[SpaceX Dragon]] / [[Falcon 9]] capsule/launcher combination.<ref name="aw20100506" /> "Bigelow offers Boeing, SpaceX, and other vehicle developers ... the promise of a sustained, large market for space transportation services."<ref name="tsr20101101">[http://www.thespacereview.com/article/1719/1 Bigelow still thinks big], ''[[The Space Review]]'', 1 November 2010, accessed 2 November 2010.</ref> 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."<ref name="tsr20101101" /> After 2010, no further concrete plans have been announced for transport with Atlas V launch vehicles.
