Yes, sometimes the goal is to blow $h!t up in the name of space
2,104Sierra Space, a leading commercial
space company at the forefront of creating and building the future of space
transportation and infrastructure for low-Earth orbit (LEO) commercialization,
announced the recent completion of its first successful Ultimate Burst Pressure
(UBP) test for the Large Inflatable Flexible Environment (LIFE TM ) habitat. The test was
sponsored by Next Space Technologies for Exploration Partnerships-2 (NextSTEP-2)
Appendix A Habitat Systems project, which is managed by NASA’s Marshall Space
Flight Center, and was performed at NASA’s Johnson Space Center. NASA softgoods
subject matter experts and ILC Dover collaborated on the test.
The test, which is the first of two sub-scale burst tests scheduled for 2022 in support of
Sierra Space’s softgoods certification, used a one-third scale of Sierra Space’s LIFE TM
inflatable habitat – which burst at 192 psi – exceeding the safety requirement of 182.4
psi. As a result, this stress test is among the highest publicly released data points for a
softgoods UBP test at any scale. Sierra Space’s will plan the next sub-scale test for
later this year.
“The LIFE habitat is one of the most innovative products designed and developed by
Sierra Space and is essential for enabling humans to safely and comfortably begin to
develop new civilizations in space,” said SVP and GM, Space Destinations, Neeraj
Gupta. “The product has many applications in low-Earth orbit and for deep-space and
surface habitation on the moon and Mars. LIFE will revolutionize humans’ ability to
commercialize and explore space and we could not be prouder to achieve this important
milestone. Sierra Space is leading the development of advanced inflatable habitat
systems and continues to be the leader in softgoods inflatable systems and
architectures.”
Sub-scale tests are used to support the overall full system development and to
determine the ability of a vehicle to withstand the maximum internal pressure required to
cause failure of the vehicle’s pressure shell, commonly known as the restraint layer.
“Sierra Space and ILC Dover, along with our partners, have created an innovative
approach to softgoods inflatable habitats,” added Shawn Buckley, LIFE Chief Engineer
and Senior Director of Engineering at Sierra Space. “This latest UBP test is a testament
The UBP test is first of several tests that will be performed over the next few years in
order to complete NASA’s certification of the LIFE TM 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 habitat will serve as both a habitation and
a payload element for the Orbital Reef commercial space station, a collaboration
between Sierra Space and Blue Origin.
