ISS Is About To Get This Weird Sounding Expansion

By Joelle Renstrom | 5 years ago

BEAMInflatable rooms aren’t just for carnivals and massive house parties anymore. The ISS is about to get one as an addition to its existing digs. BEAM (Bigelow Expandable Activity Module) will be the first privately designed and built room or habitat to be used in space when it launches next year, appropriately hitching a ride with one of SpaceX’s Falcon 9 rockets.

The habitat was conceived and constructed by Bigelow Aerospace, which won the $17.8 million contract last year. While private companies have taken over the space shuttle industry, this is the first such foray into habitat or room building for crewed systems. This is also a potentially important shift when it comes to the materials used to build space habitats, as an inflatable design would save lots of room.

BEAMOnce it gets to the station, a robotic arm will affix the 3000-pound BEAM onto a docking port on the Tranquility node. Astronauts will then begin the deployment and inflation, expanding the room into it’s full 13-foot-long, 10.5-foot-wide size. One of the ISS crew will then step inside and make history. I might send the robot in there first, just in case.

The idea of inflatable habitats isn’t new, but it is, as yet, untested. BEAM will stay in place for a few years as a means of assessing the practicality of inflatable habitats for low-Earth orbit. I really hope they fill it with multi-colored balls and start bouncing around. That would be both practical and awesome, though the lack of gravity might be an issue.

Two of Bigelow’s spacecraft are currently hanging out in low-Earth orbit and will monitor BEAM, particularly when it comes to the levels of radiation inside the inflatable room, which may be higher than the rest of the ISS. The question is, how much higher? Most structures in space are made of metal, so scientists are curious to see what happens with radiation, temperature, and the integrity of the basic design.

BEAM is intended to serve as a precursor for an entire space station in the works at Bigelow. Reports indicate that the Bigelow Aerospace Alpha Station could be at least partially operational by next year. This will be the first commercial station in space, and would, among other things, “present unique opportunities for corporations to gain significant advantages over their competition,” including the ability to put their names on the station for $25 million per year. Bigelow also claims that the station will provide benefits, including a 60-day station “vacation” package for just over $50 million. Transportation to the station would cost $26 million using the Falcon 9 and Dragon capsule, or $36 million using Boeing’s craft. And if you want to ride in space via Bigelow, you don’t have to wait for them to complete the station. You can take advantage of one of their existing travel packages.
