- Sierra Space conducted the pressure test of its inflatable space habitat called LIFE. In line with this test, the inflatable space habitat was exploded.
- Pressure testing focused on the pressure shell designed to keep the habitat intact by measuring LIFE’s ability to withstand the pressure it was subjected to.
- The company states that LIFE can easily be placed inside a rocket and create a space campus larger than the International Space Station by combining multiple modular units.
Sierra Space pushed the limits of the inflatable space living space it calls LIFE (Large Integrated Flexible Environment) and pressure-tested this structure consisting of “softgoods” or woven fabrics. In line with this test, the inflatable space habitat was exploded. LIFE represents a concept that stands for large integrated flexible media, which exhibits a solid structure when inflated.
The testing focused on the pressure shell designed to keep the habitat intact by measuring LIFE’s ability to withstand the pressure it was subjected to. This layer consists of Vectran straps and other high-strength fabrics that become stronger than steel when inflated in orbit. These Vectran belts have previously been used on Mars Rovers.
In the test, supported by NASA, Sierra Space tested LIFE’s durability by pumping air beyond the recommended level of 60.8 psi (4.19 bar). The company plans to test other parts of the structure in the coming months to evaluate LIFE’s resistance to the harsh conditions of space.
If it passes all tests successfully, Sierra Space’s LIFE could play an important role in future space missions. The company says LIFE can easily be placed inside a rocket and inflated to “the size of a three-story apartment building.” Combining multiple LIFE modular units would create a space campus larger than the International Space Station, providing ample space to live and work.
