Students code microcontrollers to send and receive radio signals, simulating communications between Earth and spacecraft.

This video explains how NASA's Deep Space Network uses a system of giant antennas located around the world – and electromagnetic energy – to talk to spacecraft.

Students kinesthetically model the mathematics of how NASA communicates with spacecraft.

Students learn how waves are used in communication between far-away spacecraft and the Deep Space Network on Earth. They then practice communicating using a similar process, and finally develop a method of communicating using repeated signals.
