Other forms: orbiters
An orbiter is a craft that circles a world rather than landing on it. The Mars orbiter, an orbiter and a lander, the orbiter relayed the signal.
It usually carries the lander there and then relays its signals home, since a small machine on the surface cannot reach Earth alone. Staying in orbit is far cheaper than landing, which is why most missions are one.
