NASA's Liquid Oxygen Flight Demonstration: A Step Towards Space Refueling and Sustainable Space Travel
Liquid Oxygen Flight Demonstration (LOXSAT)Cryogenic Fluid Management (CFM)In-Space Propellant Depots

LOXSAT is a small-scale flight demonstration of a complete cryogenic oxygen fluid management system that will be the primary payload on a Rocket Lab Photon satellite. This mission aims to determine if technologies deemed necessary for creating practical propellant depots, which could be used for future long-distance crewed spaceflight, can efficiently store, control, transfer, and pressurize liquid oxygen in low-earth orbit. These capabilities would support longer and more substantial space missions with smaller crafts, potentially leading to new destinations such as the Moon, Mars, and other deep space destinations.

Since 2021, NASA has been collaborating with cryo-engineers from Eta Space on the Liquid Oxygen Flight Demonstration (LOXSAT). The objective is to test cryogenic fluid management (CFM) technologies for building in-space propellant depots, altering the way NASA manages fuel during long-range missions.

NASA's past experiments in propellant transfer technologies utilized remote-controlled refueling robots on Earth and the International Space Station. LOXSAT plans 'gas stations' positioned in deep space, where crafts can refuel on their way to destinations like Mars. The challenge is to develop CFM systems that can maintain hydrogen and other fluids at low temperatures for extended periods in deep-space fueling stations. This could significantly impact coordinating and monitoring the demonstration of 11 CFM technologies
