The Bigelow Expandable Activity Module, known as BEAM, is successfully installed onto the International Space Station. BEAM, the size of a small bedroom, will test out a habitat for astronauts, researchers and even tourists.

A NASA ground-control team on Saturday used a robot arm to unpack an expandable module and attach it to the International Space Station, setting the stage for a novel test of a habitat for astronauts, researchers and even tourists.

The 3,100-pound (1,400 kg) module, manufactured and owned by Bigelow Aerospace, was launched aboard a SpaceX Dragon cargo capsule that reached the station last week.

The module was attached to the station at 5:36 am EDT (0936 GMT) as the station flew about 250 miles (400 km) above Earth, the U.S. space agency said during a live broadcast on NASA TV.

The Bigelow Expandable Activity Module, or BEAM, is scheduled to be inflated with air in late May, beginning a two-year experiment to see how it holds up in the harsh environment of space.

Made of impact-resistant, Kevlar-like materials and other fabrics, the lightweight habitats could save millions of dollars in launch costs compared with metal modules. They may also offer better radiation protection for astronauts, officials with NASA and Bigelow Aerospace said before the April 8 launch.

Bigelow, based in North Las Vegas, Nevada, tested two unmanned prototypes a decade ago, but BEAM is its first inflatable that will host astronauts.

The company, owned by real estate billionaire Robert Bigelow, is working on operational modules 20 times larger than BEAM, which is about the size of a small bedroom.

Dubbed the B330, it is designed primarily to be free-floating habitat, but Bigelow is talking with NASA about attaching one to the space station. It would add about 12,000 cubic feet, or 30 percent more space, to the outpost to support NASA and commercial projects.

The company is developing time-share agreements to lease space aboard the module to commercial entities, research organizations and the occasional space tourist.

NASA is interested in expandable habitats to serve as crew living quarters during three-year trips to and from Mars.

BEAM's test run is intended to see how it withstands the temperature swings and high-radiation environment of space. Members of the station crew also will install sensors to monitor orbital debris and micrometeoroid impacts.
