ARX STELLA is a pioneering space infrastructure company based in Houston, Texas, dedicated to the rapid, modular manufacturing of advanced space systems. Our core products include Exoplanetary Modules, Orbital Modules, and Nuclear Modules, designed to support humanity's expansion into space. Leveraging a fast-moving assembly line approach, similar to those utilized by Ford and SpaceX, we aim to reduce costs and accelerate deployment timelines. Our modules are designed to serve critical missions on the Moon, Mars, orbital stations, and beyond. We are closely aligned with NASA’s emerging needs for sustainable surface and orbital infrastructure, including pressurized surface habitats, orbital stations around the Moon and Mars, and advanced thermal and radiation shielding technologies.

To build the modular foundation for humanity's off-world future by delivering robust, scalable, and rapidly deployable space systems. Our mission is rooted in the belief that space is the next frontier for sustainable growth, security, and exploration. ARX STELLA is committed to empowering human presence beyond Earth by developing the critical infrastructure necessary to thrive on other worlds. We aim to democratize access to space through innovation, agility, and partnerships—enabling research, commerce, and habitation in low-Earth orbit, the Moon, Mars, and exoplanetary environments. Our focus includes supporting NASA’s Artemis and Mars architecture plans with adaptive, radiation-hardened systems that interconnect via standardized birthing and robotic interface modules.
