Explained in plain English
How do satellites get fuel?
Satellites typically carry their own fuel, usually a chemical propellant, to power small thrusters. These thrusters are crucial for making tiny adjustments to their orbit, keeping them in the right position and preventing them from drifting or, like Swift, falling. Once that fuel runs out, the satellite's operational life is largely over, unless a robot like Link intervenes.
