NASA is launching the Robotic Refueling Mission 3 early next year! This mission will test tools, technologies and techniques to transfer and freeze cryogenic propellant (e.g., liquid methane) and electric propellant (e.g., xenon) in orbit. Pictured is Senior Tools Engineer Matt Ashmore inspecting one of the tools to be used in the mission-- the Cryogen Servicing Tool.
Cryogen is used as a potent propellant or coolant to keep critical optical equipment cold and operational, and xenon is a highly efficient propellant used for solar electric propulsion. The ability to transfer and replenish both is critical to enabling long duration journeys to destinations like the Moon and Mars.
