Robert, Ryan, and Kirby Carlisle, who previously worked at SpaceX during the Falcon 9 era, founded Argo Space in late 2022 to build in-space infrastructure. Rather than focusing on rockets, the brothers developed a water-based propulsion system that leverages resources potentially harvestable on the Moon and available throughout the Solar System, eliminating the need to transport propellants from Earth.
