A trio of engineers who worked at SpaceX during the Falcon 9 era have launched their own space company, Argo Space, with a unique approach to space travel. Instead of building rockets, the Carlisle brothers are focusing on spacecraft that use water as a propellant. This innovative approach could potentially revolutionize space travel by eliminating the need for Earth-based propellants. The brothers, Robert, Ryan, and Kirby Carlisle, have a wealth of experience in the space industry, having worked on rocket launches, refurbishments, and sales during their time at SpaceX. Their new company, Argo Space, aims to build infrastructure in space and provide a more sustainable and efficient way to travel through the cosmos. Water, which is abundant in the Solar System, has been chosen as the propellant of choice. This decision is driven by the potential to harvest water on the Moon and other celestial bodies, reducing the need for resupply missions from Earth. The use of water as a propellant also offers a more environmentally friendly alternative to traditional rocket fuels. Argo Space's innovative approach has the potential to transform the space industry, making space travel more accessible and sustainable for future generations. The company's vision is to create a new era of space exploration, where spacecraft can travel efficiently and effectively without relying on Earth-based resources.
