Sierra Space Successfully Completes Second Ultimate Burst Pressure Test of its LIFE Habitat

Sierra Space, one of the leading commercial space companies building the first end-to-end business and technology platform in space, announced that the company’s LIFE habitat (Large Integrated Flexible Environment) has successfully completed its second sub-scale Ultimate Burst Pressure (UBP) test. Following the success of its first UBP test in July of this year, this second test further establishes Sierra Space as the leader in commercial space station development and the only active commercial space company to meet multiple successful UBP trials.

This latest test was performed on November 15 under NASA’s NextSTEP project for space habitation systems, which is managed by the agency’s Marshall Space Flight Center. NASA subject matter experts and ILC Dover collaborated with Sierra Space on the test, which occurred in a historic setting on Redstone Arsenal in Huntsville, Alabama. Due to the explosive nature of the test, the team placed the sub-scale space habitat in the flame trench of the Saturn 1/1B test stand, where NASA tested rockets for the Apollo program.

Sierra Space’s LIFE forms part of the company’s in-space destinations technology portfolio. The inflatable module is a three-story commercial habitation and science platform designed for low-Earth orbit (LEO) that will allow humans to live and work comfortably in space. LIFE is constructed of high-strength “softgoods” materials, which are sewn and woven fabrics – primarily Vectran – that become rigid structures when pressurized Sierra Space is working towards NASA softgoods certification and is already exceeding programmatic requirements that demonstrate LIFE has followed successful systematic and comprehensive design, fabrication and test program. The two sub-scale UBP tests in July and November achieved maximum burst pressure rates of 192 and 204 psi, respectively. Exceeding the safety requirement of 182.4 psi demonstrates that Sierra Space can meet the 4x safety factor required for softgoods inflatables within its current architecture at a one-third scale.

“The LIFE habitat module is an essential technology for enabling humans to safely and comfortably begin to develop new civilizations in space,” said Sierra Space CEO Tom Vice. “This project will service many different opportunities for the new space economy, and the results of this most recent test and milestone are testaments to the progress our team is making to enable the next chapter in space commercialization. We look forward to continuing to build this key element in our technology portfolio and paving the way for the development of advanced inflatable habitat systems and architectures.”

This series of sub-scale tests are designed to support LIFE’s overall, full-scale development and future inflatable habitats, as Sierra Space builds the next generation of inflatable habitat architectures. These early “fleet” leader tests provide the design and analysis data to determine the safety and reliability of the inflatable architecture systems. “Sierra Space is making incredible strides in the inflatable habitat technology development roadmap. In working with our partners ILC Dover and NASA, Sierra Space is quickly moving closer to softgoods certification,” added Shawn Buckley, LIFE Chief Engineer and Senior Director of Engineering at Sierra Space. “This second successful UBP test proves we can demonstrate design, manufacturing, and assembly repeatability, all of which are key areas for certification.”

Full-scale LIFE UBP tests will begin in 2023, in order to complete NASA’s certification of the habitat’s primary structure for human use in space. NASA’s NextSTEP program falls under the HQ Explorations Systems Development Mission Directorate (ESDMD) Technical Integration’s (TI) Pre-Formulation (PF) Habitation Team. For NextSTEP-2, Sierra Space is focused on performing critical risk reduction tests and assessing LIFE’s extensibility to multiple space destinations including the moon and Mars.

Among other missions in coming years, LIFE will serve as both habitation and a payload element for the Orbital Reef commercial space station, a collaboration between Sierra Space and Blue Origin.
