Sierra Space LIFE Habitat Ultimate Burst Pressure Test

Sierra Space announced on 2022-09-13 “Sierra Space’s LIFE Habitat Completes Successful Ultimate Burst Pressure Test”. This is a one third scale model of the pressure containment layer for their Large Inflatable Flexible Environment (LIFE) habitat intended for use on future space stations and vehicles. The safety criterion was that it must withstand at least 182.4 pounds per square inch pressure (1257.6 kilopascal, 12.4 atmospheres), and the structure actually burst at 192 psi. This is said to be stronger than typical hard structure pressure vessels used in spacecraft.
