At the International Space Station on Saturday, May 28, 2016, a Bigelow Expandable Activity Module (BEAM) was finally inflated after a failed first attempt on May 26th. Space X delivered BEAM to the ISS in early April 2016, where it was attached to test its durability in space for the next two years. Blown up to full size, the new experimental BEAM module gives the ISS 13 feet by 10.5 feet more space for science experiments.
