In late 2022, the three Carlisles founded Argo Space to build infrastructure in space. Their vision was not just in-space transportation but also removing the need to use propellants from Earth to move around the heavens. They chose water, which is potentially harvestable on the Moon and found all over the Solar System, as a means of propulsion.

The propulsion system is basically a small rocket that uses hydrogen and oxygen as propellants. However, instead of launching with separate tanks of liquid hydrogen and liquid oxygen, Chiron starts with liquid water. In space, the vehicle uses solar power to split water into hydrogen and oxygen gases and burns them to generate thrust.
