Orbit Refueling Device For Deep Space Missions
Engadget • • science
Key Points:
- NASA is developing in-orbit refueling technology for deep space missions, focusing on a "cryocoupler" nozzle designed by L3Harris to enable spacecraft to connect with orbiting gas stations and refuel before leaving Earth's vicinity.
- The cryocoupler must transfer extremely cold propellants like liquid hydrogen and oxygen without leaks, requiring specialized materials, strong seals, and fully automated operation to avoid spacewalks.
- Tests have involved running liquid nitrogen at -321°F through the device to evaluate its performance under extreme temperatures and its ability to handle misaligned dockings.
- While current tests are basic, future evaluations will be mission-specific to ensure the cryocoupler meets the demands of various spaceflight scenarios.
