Satellite refueling is a process that allows spacecraft in orbit to replenish their fuel supplies. This technique extends the operational life of satellites, enabling them to continue functioning for longer periods without the need for a costly replacement. Refueling can be done using specialized spacecraft designed to transfer fuel to the satellite. The process typically involves a robotic arm or other mechanisms to connect the refueling vehicle to the satellite. Once connected, fuel is transferred, allowing the satellite to adjust its orbit or maintain its position. This innovation is crucial for future space missions, including those involving deep space exploration and space tourism.
