Students gain first-hand experience with the Doppler effect and how it's used by NASA’s Deep Space Network.

Students learn how waves are used in communication with spacecraft and practice communicating using a similar process.

In this intermediate-level programming challenge, students use microdevices along with light and mirrors to build a relay that can send information to a distant detector.

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

NASA has dozens of robotic spacecraft exploring our solar system – and beyond. So how exactly do we navigate spacecraft that are so far away?

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.

In this advanced programming activity, students will construct a light-wavelength detector to model future technology for communicating with spacecraft.

In this illustrated math problem, students use the mathematical constant pi to compare signal strength between traditional radio wave communication and the Deep Space Optical Communication system.
