Orbital Refueling

Orbital refueling is a technology that enables spacecraft to refuel in orbit, extending their mission duration and capabilities.

It works by using specialized spacecraft to transfer fuel to other spacecraft, allowing them to continue operating without needing to return to Earth.

This technology matters because it enables longer and more complex space missions, and could play a key role in future deep space exploration.
