About
4 Earth 2 Mars is leading the development of CATs&DOG®, a modular and circular building system designed for reconfigurable construction in extreme environments—on Earth and the Moon.
Backed by Autodesk Foundation, EIT Climate-KIC, Rabobank, and supported by ESA, our EU–UK consortium has submitted proposals to both EIC Pathfinder Challenge 2025 and ESA OSIP. We are alumni of:
-
Berkeley Lab IMPEL Accelerator (2021)
-
EIT ClimAccelerator – Circular Built Environment (2023)
-
SBIC Soft Landing Program (2024)
Our flagship initiative—Analog Circular BlueMoon Village—has secured two launching customers and demonstrates a €40M+ market opportunity, even at early TRL. Designed as both a tech demonstrator and modular village, the system is attracting attention from Earth-focused and space-focused partners alike.
CATs&DOG® combines:
-
AI-optimized design software (using Earth Observation Data)
-
Mobile production units for local fabrication
-
DIY building systems for affordable housing
-
Robotic deployment systems for lunar applications
We are now seeking partners in AI, robotics, circular materials, space architecture, structural testing, and policy/funding support to co-develop TRL 2–4 prototypes and advance to TRL 5–7 with ESA and commercial partners.
If you're ready to build the future—modular, circular, and Moon-ready—get in touch.
