Refueling is the process of replenishing the propellant or fuel of a spacecraft while it is in orbit. This capability is crucial for extending the operational life of satellites and other space vehicles, allowing them to continue performing their missions without needing to return to Earth for fuel resupply. By enabling extended missions, refueling supports on-orbit servicing and life extension efforts, helping to reduce the amount of space debris generated by decommissioned satellites.
congrats on reading the definition of Refueling. now let's actually learn it.
