The International Space Station is set to get a new room for the first time in five years.
The Bigelow Expandable Activity Module, or BEAM, blows up like a balloon after it's attached to the station.
And it's soft-sided like a balloon, too. But Bigelow Aerospace has built in layers of micrometeoroid protection, which it says will stop orbital debris just as effectively as the rigid modules that make up the rest of the station.
Bigelow will be testing BEAM for a while before any astronauts start living in a bubble. The ISS crew will use it as storage while Bigelow checks its durability and its resistance to radiation.
BEAM will hitch a ride aboard SpaceX's CRS-8 supply mission. Before it's inflated, it's about 10 times smaller than its blown-up size.
This makes inflatable habitats an attractive option for space construction. The smaller and lighter something is, the cheaper it is to get into orbit.
Bigelow plans to eventually move on to larger versions, which could see use in orbital science or long-term missions to the moon or Mars.
SpaceX's launch is scheduled for April 8, weather permitting.
