2025 Human Lander Challenge

In-space propulsion systems utilizing cryogenic liquids as propellants are necessary to achieve NASAs exploration missions to the Moon, and later to Mars. In current state of the art SOA human scale, in-space propulsion vehicles, cryogenic liquids can be stored for several hours. For the planned HLS mission architecture to close, cryogenic liquids must be stored 8230;. https://www.nasa.gov/gener...
