Q:

How does NASA control a space probe's movement?

A:

NASA and the probes communicate using radio waves, just like a walkie talkie. And then, just like on a remote controled car, NASA can use these signals to tell the probe what to do.

 

Probes have two ways of moving in space. Some have just one of these two things, some have both. They use thrusters and rotation wheels. They allow the probe to turn, speed up and slow down. NASA can then move the probe at a distance, and send it on some very distant missions that way!
