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.
