The first private space station is set to be an inflatable - and could launch in 2020.

United Launch Alliance will team with billionaire entrepreneur Robert Bigelow to market and fly habitats for humans in space, the two revealed today.

An inflatable module based on the Bigelow technology is currently being attached to the International Space Station.

United Launch Alliance will team with billionaire entrepreneur Robert Bigelow to market and fly habitats for humans in space - with the first blasting off in 2020.

HOW THEY WORK

Bigelow has designed inflatable space habitats made of a Kevlar-like material and other fabrics that protect against impacts from orbiting debris.

They are folded for launch, then inflated with air once aloft.

The light, compact habitats should save millions of dollars in launch costs, the companies say.

The project hinges on space taxis being developed by SpaceX, Boeing Co and other firms, ULA and Bigelow said on Monday.

The agreement, announced at a news conference at the U.S. Space Symposium in Colorado Spring, Colorado, includes a 2020 launch of a 12,000-cubic foot (330-cubic meter) inflatable habitat aboard a ULA Atlas 5 rocket, currently the only vehicle with a big enough payload container to hold the module.

Bigelow told the news conference that partnering with ULA, a joint venture of Lockheed Martin Corp and Boeing, is 'a potentially enormously important relationship,' to open space to non-government research, commercial endeavors and tourism.

ULA and Bigelow did not give details on their alliance. ULA President and Chief Executive Tory Bruno said at the news conference that ULA is contributing 'resources of technology and talent.

'We don't talk about dollars and investment.

'You'll see as time goes by what this fully encompasses.'

The design was evolved from NASA's TransHab habitat concept. The B330 will have 330 cubic meters (12,000 cu/ft) of internal space. The craft will support zero-gravity research including scientific missions, manufacturing processes, a destination for space tourism and a craft for missions destined for the Moon and Mars.

Bigelow Aerospace has been working on inflatable habitats for 15 years.

The Bigelow Expandable Activity Module, Beam for short, will stay on the station for two years, with astronauts occasionally entering it. It will be the first time an astronaut steps inside an expandable habitat structure in space. The pod's size, compared to an average man, is pictured

A miniature version of the expandable, fabric module arrived at the International Space Station on Sunday aboard a SpaceX Dragon cargo ship.

The Bigelow Expandable Activity Module, or BEAM, is expected to be attached to a station docking port on Saturday and inflated next month for a two-year trial run.

BEAM is the firm's first manned spacecraft. Bigelow had previously launched two unmanned prototypes in 2006 and 2007.

WHAT IS THE BIGELOW EXPANDABLE ACTIVITY MODULE?

BEAM (CGI pictured) will be the first inflatable space habitat to ever be attached to the International Space Station (ISS)

Beam will be the first inflatable space habitat to ever be attached to the International Space Station (ISS).

Designed by Nasa and Bigelow Aerospace, Beam is scheduled to launch on the eighth SpaceX Commercial Resupply Service mission, due to take off on 8 April.

Made up of aluminum and soft fabric, BEAM is designed to pack down into a relatively compact 5.7 feet (1.7 metres) long and just under 7.75 feet (2.4 metres) in diameter when stowed for the flight into space.

When it is attached to the station's structure and inflated, it will expand to 12 feet (3.7 metres) long and 10.5 feet (3.2 metres) in diameter.

Although this will be the first of these habitats tested on the ISS, Nasa thinks expandables could be a key technology to help humans on the journey to Mars.

Bigelow plans to follow BEAM with modules that are 20 times larger to serve as space outposts that will be leased to companies and research organizations.

Bigelow said he also would like to attach one of the modules, known as B330, to the space station for use by the National Aeronautics and Space Administration and commercial customers.

The projects are dependent on commercial space transportation services, such as those under development by SpaceX and Boeing, to fly astronauts to and from the space station for NASA.

THE HISTORY OF BEAM

Bigelow Aerospace won't divulge the material used for Beam's outer layers - or even how many layers - just that the layers are spread out to absorb and break up any penetrating bits of space junk.

Back when Nasa was working on the technology in the 1990s, a combination of Nextel, Kevlar, foam and other fabric formed the multilayer shield.

Nasa called its project TransHab, for Transit Habitat. It never flew to space, despite elaborate blueprints and ground mock-ups. Designers envisioned an inflatable, four-level compartment, complete with dining, sleeping and exercising areas for station crews.

Nasa outlined the four possible ways it might expand, shown, in a newly released video. Although this will be the first of these habitats tested on the ISS, Nasa thinks expandables could be a key technology to help humans on the journey to Mars

Congress cancelled TransHab in 2000 and Bigelow Aerospace bought the patent from Nasa.

The company launched a pair of expandable spacecraft a decade ago from Russia as an experiment. Called Genesis I and II, they're still orbiting.

Nasa, meanwhile, paid Bigelow Aerospace $17.8 million for the upcoming test flight, making the Beam the most affordable module ever launched to the space station, said Michael Gold, director of operations and business growth for Bigelow Aerospace.
