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— 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, t he 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'.
