Sierra Space’s LIFE habitat following a full-scale ultimate burst pressure test at NASA’s Marshall Space Flight Center in Huntsville, AlabamaSierra Space An element of a NASA-funded commercial space station, Orbital Reef, under development by Blue Origin and Sierra Space, recently completed a full-scale ultimate burst pressure test as part of the agency’s efforts for new destinations in low Earth orbit.

Orbital Reef includes elements provided by Sierra Space, including the LIFE (Large Integrated Flexible Environment) habitat structure.

The inflatable habitat is fabricated from high-strength webbings and fabric that form a solid structure once pressurized. The multiple layers of soft goods materials that make up the shell are compactly stowed in a payload fairing and inflated when ready for use, enabling the habitat to launch on a single rocket.

Dr. Tom Marshburn, Sierra Space chief medical officer, speaks with members of the Sierra Space team following the burst test.Sierra Space The pressurization to failure during the test demonstrated the habitat’s capabilities and provided the companies with critical data supporting NASA’s inflatable softgoods certification guidelines, which recommend a progression of tests to evaluate these materials in relevant operational environments and understand the failure modes.

Prior to this recent test, Sierra Space conducted its first full-scale ultimate burst pressure test on the LIFE habitat at Marshall in December 2023. Additionally, Sierra Space previously completed subscale tests, first at NASA’s Johnson Space Center in Houston and then at Marshall as part of ongoing development and testing of inflatable habitation architecture.

The LIFE habitat will be part of Blue Origin’s commercial destination, Orbital Reef.Sierra Space NASA supports the design and development of multiple commercial space stations, including Orbital Reef, through funded and unfunded agreements. The current design and development phase will be followed by the procurement of services from one or more companies.
NASA’s goal is to achieve a strong economy in low Earth orbit where the agency can purchase services as one of many customers to meet its science and research objectives in microgravity. NASA’s commercial strategy for low Earth orbit will provide the government with reliable and safe services at a lower cost, enabling the agency to focus on Artemis missions to the Moon in preparation for Mars while also continuing to use low Earth orbit as a training and proving ground for those deep space missions.

3 Min Read NASA Sponsors New Research on Orbital Debris, Lunar Sustainability
From lunar orbit, astronauts pointed cameras out the window of their spacecraft to capture photos of the moon's surface. Credits: NASA As part of NASA’s commitment to foster responsible exploration of the universe for the benefit of humanity, the Office of Technology, Policy, and Strategy (OTPS) is funding space sustainability research proposals from five university-based teams to analyze critical economic, social, and policy issues related to Earth’s orbit and cislunar space.
The new research awards reflect the agency’s commitment identified in NASA’s Space Sustainability Strategy to ensure safe, peaceful, and responsible space exploration for future generations, and encourage sustainable behaviors in cislunar space and on the lunar surface by ensuring that current operations do not impact those yet to come.
Three of the five awards will fund research that addresses the growing problem of orbital debris, human-made objects in Earth’s orbit that no longer serve a purpose. This debris can endanger spacecraft, jeopardize access to space, and impede the development of a low-Earth orbit economy.
The remaining two awards focus on lunar surface sustainability and will address key policy questions such as the protection of valuable locations and human heritage sites as well as other technical, economic, or cultural considerations that may factor into mission planning.
“The sustainable use of space is critical to current and future space exploration,” said Ellen Gertsen, deputy associate administrator for the Office of Technology, Policy, and Strategy (OTPS) at NASA Headquarters in Washington. “Mitigating the risks of orbital debris and ensuring future generations can utilize the lunar surface are of paramount importance. These awards will fund research to help us understand the economics, the policy considerations, and the social elements of sustainability, generating new tools and evidence so we can make better-informed decisions.”
A panel of NASA experts selected the following proposals, awarding a total of about $550,000 to fund them:
Lunar surface sustainability
“A RAD Framework for the Moon: Applying Resist-Accept-Direct Decision-Making,” submitted by Dr. Caitlin Ahrens of the University of Maryland, College Park “Synthesizing Frameworks of Sustainability for Futures on the Moon,” submitted by research scientist Afreen Siddiqi of Massachusetts Institute of Technology Orbital Debris and Space Sustainability
“Integrated Economic-Debris Modeling of Active Debris Removal to Inform Space Sustainability and Policy,” submitted by researcher Mark Moretto of the University of Colorado, Boulder “Avoiding the Kessler Syndrome Through Policy Intervention,” submitted by aeronautics and astronautics researcher Richard Linares of the Massachusetts Institute of Technology “Analysis of Cislunar Space Environment Scenarios, Enabling Deterrence and Incentive-Based Policy,” submitted by mechanical and aerospace engineering researcher Ryne Beeson of Princeton University Share
