At the International Space Station, the Bigelow Expandable Activity Module (BEAM) was expanded to its full volumetric size May 28 through the introduction of air by the Expedition 47 crew onboard the station. BEAM, which was launched on a SpaceX/Dragon cargo craft April 8 and installed on the aft port of the Tranquility module April 16, is the first expandable component to be attached to the station and a prototype of structures that may be used in the future for habitats associated with deep space exploration. Measuring 11.6 x 10.5 feet, BEAM is expected to remain attached to the station for two years with crew members making occasional visits inside to check its systems.
