Brothers aim to create moon water-powered spacecraft after SpaceX experience.
Argo Space Corporation, founded by three SpaceX veterans, plans to build reusable spacecraft propelled by water harvested from the moon to create an in-space transportation network. The company's first spacecraft, the Argonaut, is designed to perform energy-intensive transfers to geosynchronous and beyond, and will depend on lunar water harvested and stored in-space for refueling. Argo recently closed a $2 million funding round to continue development on its technology. The company plans to generate revenue from in-space transportation services until it can get hardware on the moon and prove out its plan.
