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.

Students draw and interpret topographic maps while learning about technology used to map Earth's surface, the seafloor, and other worlds.

In this activity, students learn how light and energy are spread throughout space. The rate of change can be expressed mathematically, demonstrating why spacecraft like NASA’s Juno need so many solar panels.

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 learn how Mars rovers use spectroscopy to study the chemical composition of rock samples on the Red Planet then model the process in the classroom.

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

In this illustrated problem set, students use pi to compare the sizes of Mars landing areas, calculate the length of a year for a distant solar system object, measure the depth of the ocean from an airplane, and determine the diameter of a debris disk.

In this illustrated math problem, students use pi to measure the water depth of an area mapped by the CORAL mission.
