> What counts as a drone? Satellites can be steered, are those drones?

Traditionally, any remote controlled aircraft is a drone, it seems fair to say any remote controlled spacecraft is also a drone.

The first drone, from which the term 'drone' came, was a radio controlled de Havilland Tiger Moth created in 1935, named "Queen Bee". It was a gunnery target drone, built for the purpose of being shot down, intended to fly only once. 'Drone' is a pun on that single-flight use and the name 'Queen bee'; male bees, which fly only once before dying, are called drones.

These days it's trendy for people to put forth their own definitions of 'drone' that have qualifiers like "it must have autonomy" or "it must be able to land". But the first drone had neither capability and the term itself is at odds with the latter.
