<\/p>\nWhile Bigelow Aerospace\u2019s expandable module, BEAM, continues to perform above all expectations while attached to the International Space Station (ISS), the company has larger ambitions for its range of modules, centered around the B330 \u2013 a huge inflatable module. The key focus is on attracting NASA to select B330 as a transportation module for long-duration trips to Mars.<\/p>\n

Bigelow already has a wealth of experience in space, ranging back to the days of its Genesis modules that tested the technology that has matured into their latest designs.<\/p>\n
Genesis I, the world\u2019s first inflatable spacecraft, was carried into its 320 mile orbit on top of a converted Cold War-era ICBM (Intercontinental Ballistic Missile) in December 2006.<\/p>\n
\u201cWith Genesis I, it was our first rodeo. We didn\u2019t know exactly what to expect,\u201d noted program officials as they followed it up with the Genesis II module a year later.<\/p>\n

The company\u2019s ambitions inflated into concepts for Moon and Mars bases, utilizing NASA experience via an unfunded Space Act Agreement (SAA). During this period, Bigelow was tasked with creating two reports (or Gates) to NASA on the future capability of their inflatable systems.<\/p>\n
Gate 1 contained everything from an examination of past spaceflight accomplishments to future operations in Low Earth Orbit (LEO) to Lagrangian Point missions to cis-lunar (the region outside Earth\u2019s atmosphere extending out to just beyond the Moon\u2019s orbit) missions.<\/p>\n
Gate 2 was tasked with identifying and establishing mission proposals based on the company\u2019s stated contributions identified in Gate 1 and Bigelow\u2019s stated mission and exploration interests.<\/p>\n
Some of the concepts were highly impressive, not least the huge Olympus Carrier module.<\/p>\n

However, the B330 was highlighted as both highly capable and with the ability to be lofted on a single launch.<\/p>\n
While this work was ongoing, Bigelow Aerospace was already working towards a demonstration module that could be launched on a Cargo Resupply Mission (CRS) and attached to the ISS for testing.<\/p>\n
The Bigelow Expandable Activity Module (BEAM) rode inside SpaceX\u2019s CRS-9 Dragon in 2016 and was installed on to the Node 3 Aft port of the Station.<\/p>\n

<\/p>\n

It was then expanded and was set to remain in the ISS for only a matter of months. But its performance has been flawless to date and it still resides on Node 3 today and is being used as a storage facility for the ISS crew.<\/p>\n
Bigelow Aerospace had additional interest in the ISS in 2016 when they announced a partnership agreement with United Launch Alliance (ULA) to launch two B330 space habitats.<\/p>\n
Bigelow noted that both B330s could be used as free-flying orbital labs while the option existed \u2013 pending approval from NASA \u2013 to dock one of the B330s to the ISS.<\/p>\n

Notional readiness in 2019 for launch in 2020 has not advanced as a firm plan since, but it again highlighted the focus on the B330.<\/p>\n
This module is again the focus with the latest drive at Bigelow Aerospace, which invited media to check out work involved with a two-week-long ground test of an all-steel testing unit (Mars Transporter Testing Unit) of a B330 under the NextSTEP Phase 2 program for NASA.<\/p>\n
This module is one of six demonstration projects funded as part of the NASA program, with other companies building full-sized NextSTEP-2 prototypes for space habitats \u2013 namely Boeing, Lockheed Martin, Northrop Grumman, Sierra Nevada Corp., and Nanoracks.<\/p>\n
During the media event, Bigelow provided more details on the module while expanding on its potential use in numerous deep space exploration roles.<\/p>\n
\u201cThe B330 is an autonomous, expandable independent space station that gets to space in a single launch. This large space station can accommodate four people indefinitely and five people for many months,\u201d noted Robert T. Bigelow in an overview to accompany the media event in Las Vegas.<\/p>\n

\u201cEquipped with two galleys, two toilets, enormous cargo space and two dissimilar propulsion systems, this is the ideal habitat for a long-duration space mission.\u201d<\/p>\n
Speaking directly to the availability of such a module to NASA, should Bigelow Aerospace proceed through the NextSTEP-2 Program, Mr. Bigelow said that the first B330 can be built in 42 months upon receiving authority to proceed. The second B330 can be built within 28 months of the first, and the third B330 could be built within 22 months of the second.<\/p>\n
\u201cThe ground test is an important milestone for Bigelow Aerospace and B330. We are hosting over 60 NASA engineers, test leads and support staff as well as eight astronauts. In contrast to the other NextSTEP Phase 2 participants, we chose to keep our ground units at our facility so we could continue to develop and test. We also have many units that are too large and complex to feasibly transport back and forth.\u201d<\/p>\n
Promoting its potential as a transportation module for crews heading out on the long journey to Mars, Mr. Bigelow touted the B330\u2019s NASA heritage and lessons employed from previous studies, not least the issue of protecting crews from radiation.<\/p>\n
\u201cThe B330 has evolved from NASA heritage technology from the Transhab program. Expandable habitat technology was created from the Transhab program with the purpose of taking humans to Mars. This is important. In deep space, expandable structures have the potential to provide better protection against secondary radiation than traditional aluminum structures,\u201d he noted.<\/p>\n
