It's pump-it-up day at the International Space Station.
NASA is releasing air into an inflatable room delivered last month by SpaceX. If all goes well, the pod will swell four times in volume and demonstrate a new way of living for astronauts. The hour-long process began Thursday morning 250 miles above Earth.
Astronaut Jeffrey Williams opened a valve that allowed air to slowly flow into the inflatable chamber, called BEAM. That stands for Bigelow Expandable Activity Module. It's the creation of Bigelow Aerospace, founded by hotel entrepreneur Robert Bigelow. NASA paid the North Las Vegas company $17.8 million to test the inflatable-habitat concept at the space station.
Get live updates from Mission Control as the first human-rated expandable habitat is deployed to full size. Tune in to NASA Television to watch it: http://bit.ly/2491WVa.
Williams and his crewmates won't venture inside BEAM - the world's first inflatable room for astronauts - until next week.
