CAPE CANAVERAL, Fla (Reuters) - 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
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 on Sunday.
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
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.

“Our hope is that NASA would be the primary customer for that
structure,” Bigelow said at a press conference on Monday at the
Space Symposium in Colorado Springs.
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
“This type of architecture has never been flown before,” Bigelow
told reporters before launch. "We’re not 100 percent sure of its
behavior. It is a testing station. That is the whole point here, in
all respects,” Bigelow said.
