    BEAM is composed of two metal bulkheads, an aluminum structure, and multiple layers of soft fabric with spacing between layers, protecting an internal restraint and bladder system; it has neither windows nor internal power. The module is scheduled to be expanded about a month after being attached to the space station. It will be inflated from its packed dimensions of 2.16 m (7.1 ft) long and 2.36 m (7.7 ft) in diameter to its pressurized dimensions of 4.01 m (13.2 ft) long and 3.23 m (10.6 ft) in diameter. The module has a mass of 1,413.0 kg (3,115.1 lb), and its interior pressure will be 14.7 pounds per square inch (1 atm), the same as inside of the ISS.
