NASA Tests In-Orbit Refueling Tech

NASA is testing a new “cryocoupler” designed by L3Harris to enable in-orbit refueling for deep space missions. The automated device acts like a gas pump nozzle, allowing spacecraft to transfer cryogenic propellants like liquid hydrogen and oxygen without requiring spacewalks.
Recent tests used liquid nitrogen at negative 321 degrees Fahrenheit to evaluate the coupler’s seals and its ability to handle misaligned dockings. The technology aims to support long-duration exploration by allowing ships to refuel before leaving Earth’s orbit.
