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.

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.
