Inflatable Space Habitat To Be Tested On The ISS
Space habitats have long been an object of fascination for thinkers, dreamers, and engineers. Science fiction is littered with space habitats, whether in books or movies. And their designs have ranged from titanic, uber-engineered types to fanciful, organic types.Bigelow Aerospace is one company that is focused on creating affordable, practical space habitats. Inflatability is the name of the game for Bigelow, and now, one of their habitat modules is going to be tested on the ISS for a 2-year period. The BEAM, or Bigelow Expandable Activity Module, will be launched aboard a SpaceX Dragon on Friday April 8th, for a 2-day journey to the ISS.The BEAM travels as an 8 foot bundle, but once it’s attached to the ISS, and inflated by astronauts, it will be large enough to hold a car. However, astronauts won’t be living inside it; rather, the BEAM will be tested for 2 years to see how it holds up. The objectives for this 2 year mission include:
- Demonstrating launch and deployment, as well as folding and packing techniques.
- Determining radiation protection capability.
- Demonstrating design performance such as thermal, structural, mechanical durability, long-term leak performance, etc.
- Increasing Technology Readiness Level (TRL) of expandable habitat technology
“The International Space Station is a uniquely suited test bed to demonstrate innovative exploration technologies like the BEAM,” said William Gerstenmaier, associate administrator for human exploration and operations at NASA Headquarters in Washington. “As we venture deeper into space on the path to Mars, habitats that allow for long-duration stays in space will be a critical capability. Using the station’s resources, we’ll learn how humans can work effectively with this technology in space, as we continue to advance our understanding in all aspects for long-duration spaceflight aboard the orbiting laboratory.”The obvious risk to an inflatable space habitat is puncturing; not only from meteoroids, but from the —> Read More
