The 2,426-pound module was built by engineer and manufacturing company, ILC Dover, in 2007 and tested at NASA Langley. The Planetary Surface Habitat and Airlock Unit, has helped researchers in determining the best possible materials for sustaining human life on the moon for more than one year. A key component of the multilayer inflatable module is its ability to be compressed into a much smaller space than it would use when fully set up. The structure is made of temperature-insulated and impact-detection layers
