The Bigelow Expandable Activity Module -- also known as BEAM -- is an additional spaceship room that offers more mobility and accommodations at an instance's notice thanks to its inflatable design. The module is engineered to provide a small yet comfortable space that goes beyond what is offered within the dimensions of the existing ship.
The BEAM offers 565-feet of space designed exclusively for the ISS mission and will be tested to see its functionality in space. Astronauts attending the mission will monitor the room's performance that will offer a two year lifespan before separating entirely from the spaceship. Consumers can watch where the module ends up via a live cam feed inside.
BEAM will act as a prototype to test adding extra room aboard aircrafts as well as functioning as an abode on other planets.
