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.
