Gravity and Radio Waves to Study Planets and Moons

How NASA Uses Gravity and Radio Waves to Study Planets and Moons

A spacecraft uses radio antennas to communicate with the deep space Network on Earth which in turn transmits radio signals back to the spacecraft. every spacecraft travels in a predetermined path emitting radio signals as it orbits around its Target scientists. Messages travel through space as radio waves, just like the radio waves that you receive with a car radio. Each spacecraft has a transmitter and a receiver for radio waves as well as a way of interpreting the information received and acting on it.
