The first human-rated expandable habitat was attached this morning to the International Space Station.
ISS crew used the station's Canadian robot arm to remove the Bigelow Expandable Activity Module (BEAM) from the unpressurized trunk of the SpaceX Dragon. The arm attached BEAM to the Tranquility module of the station.
BEAM will be attached to ISS for two years to test the technology, which may be the prototype of next-generation space stations to be occupied in the 2020s.
UPDATE April 16, 2016 8:45 PM EDT — NASA posted on YouTube this video clip of the BEAM installation.
