BOXABL Unveils Rego-Brix Concept for Radiation Shielding Using Lunar Regolith
Concept proposes modular building blocks designed to convert local moon dust into protective habitat shielding
LAS VEGAS, June 11, 2026 /PRNewswire/ -- BOXABL today introduced Rego-Brix, a BOXABL developed, radiation-shielding system designed to address one of the most significant obstacles facing long-duration human habitation beyond Earth: exposure to galactic cosmic radiation. The new concept focuses on utilizing regolith—the loose rock and dust covering the lunar surface—to create modular shielding structures that can surround habitats without requiring large quantities of protective material to be launched from Earth.
The concept is presented in BOXABL's video "DON'T DIE ON THE MOON (Part 2) — Rego-Brix by BOXABL," which explores radiation protection for future lunar settlers. The video outlines how locally sourced regolith could be incorporated into modular shielding systems to reduce launch requirements and support long-term habitation.
While transportation and deployment remain critical considerations for lunar infrastructure, long-term astronaut safety presents an equally important challenge. According to NASA, galactic cosmic rays are constantly present from all directions in environments with little or no atmosphere — such as space or the Moon. Long-term exposure has been linked to DNA damage, increased cancer risk, cognitive and memory impairment, heart disease, cataracts, and potentially accelerated aging and neurodegenerative conditions.
The Rego-Brix system provides a practical approach to mitigating that risk by leveraging materials already available at the destination. The concept consists of modular, nestable components that can be transported efficiently and subsequently filled with local regolith to form protective barriers around living quarters. Designed to fold flat for transport and expand on-site, the system seeks to dramatically reduce the volume required to launch shielding materials from Earth.
"The moon has plenty of dust and rock, but very little natural protection from radiation," said BOXABL CEO Paolo Tiramani. "Rego-Brix was conceived around a simple idea: use what's already there. By creating a structured system designed to hold and organize lunar regolith around habitats, we set out to explore whether local materials could help address one of the most significant challenges facing long-term human presence beyond Earth. We believe technologies that leverage in-situ resources will play an important role in the future of space settlement."
Rego-Brix is envisioned as a complementary system to UFO (BOXABL's foldable habitat unit), creating a two-part approach to early-stage off-world settlement: rapidly deployable habitats paired with locally sourced radiation shielding. Together, the concepts explore how future explorers may one day establish safer, more sustainable living environments on the moon and beyond.
BOXABL, which holds patents related to the Rego-Brix concept, has stated that it intends to make the Rego-Brix concept available on a royalty-free basis, reflecting the company's belief that technologies supporting astronaut safety and long-term habitation may benefit from broad collaboration across the global space community.
BOXABL is currently completing a merger with FG Merger II Corp. (NASDAQ:FGMC), which will result in the combined company listing on Nasdaq under the ticker symbol 'BXBL'.
