Successful failure: Sierra Space's inflatable habitat blows up as planned
- ggm 2y agoFinally! Somebody prints the PSI info. The “ultimate burst pressure” test of the inflatable module was conducted at NASA’s Marshall Space Flight Center. As the name suggests, the purpose of the test is to inflate the unit until it bursts. In this instance, engineers inflated the module to 77 psi before it burst, proving that it exceeded NASA’s recommended safety level of 60.8 psi by 27%. So it failed more than a quarter ABOVE the recommended safety PSI levels. A space suit is inflated to 4-5psi, earth standard is 14psi and thats what ISS is pressurised at. So this safety pressure is itself 4x standard pressure, and the test exploded 5x standard pressure.
