BEAM, the Bigelow Expandable Activity Module, was successfully expanded Saturday beginning two years of tests to demonstrate the new expandable technology. BEAM was pressurized and expanded to its full volume, width and length this weekend after 25 pulses of air were introduced into the new module.

BEAM leak checks are underway and will continue before astronaut Jeff Williams gets the go to enter the module on June 6. Williams will install sensors inside BEAM to measure its environment.

Japan's Kibo lab module is sending more CubeSats into orbit this week from a small satellite deployer. The CubeSats are supporting research such as communications and Earth observations sponsored by government, education and private organizations.

Back inside the International Space Station, the six-person Expedition 47 crew was exploring human research and advanced physics in microgravity. The crew was also setting up science gear and maintenance hardware and continued packing the Orbital ATK Cygnus cargo craft before its June 14 departure.

BEAM Fully Expanded and Pressurized

Pressurization of the Bigelow Expandable Activity Module (BEAM) began at 4:34 p.m. EDT, and the eight tanks filled with air completed full pressurization of the module 10 minutes later at 4:44 p.m. BEAM's pressure will be equalized with that of the International Space Station, where it will remain attached for a two-year test period.

The module measured just over 7 feet long and just under 7.75 feet in diameter in its packed configuration. BEAM now measures more than 13 feet long and about 10.5 feet in diameter to create 565 cubic feet of habitable volume. It weighs approximately 3,000 pounds.

During the next week, leak checks will be performed on BEAM to ensure its structural integrity. Hatch opening and NASA astronaut Jeff Williams' first entrance into BEAM will take place about a week after leak checks are complete.

BEAM is an example of NASA's increased commitment to partnering with industry to enable the growth of the commercial use of space. The project is co-sponsored by NASA's Advanced Exploration Systems Division and Bigelow Aerospace.

Expandable habitats are designed to take up less room on a spacecraft but provide greater volume for living and working in space once expanded. This first test of an expandable module will allow investigators to gauge how well the habitat performs and specifically, how well it protects against solar radiation, space debris and the temperature extremes of space.
