This space company is betting its future on a propellant available everywhere
Summary
Argo Space, founded by former SpaceX engineers, aims to build in-space infrastructure and use water as a propellant to enable a transportation network between LEO, GEO, and the Moon. The approach relies on solar-powered electrolysis to split water into hydrogen and oxygen for propulsion, with water also serving as coolant and radiation shielding. Navigator's demo mission faced a power issue, and the company plans Chiron missions in 2027 and a larger Argonaut vehicle, with launch plans involving a non-SpaceX launcher and a government-furnished option.
