These 60-second videos answer some of the most frequently asked questions about our planetary neighbor, Mars, and the spacecraft that explore it.

Students use the Danjon Scale of Lunar Eclipse Brightness to illustrate the range of colors and brightness the Moon can take on during a total lunar eclipse.

Explore space and science activities that students can do with NASA at Home, including video tutorials for making rockets, Mars rovers, Moon landers, and more.

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 build a rubber-band-powered rover that can scramble across the room.

Students modify a paper cup so it can zip down a line and drop a marble onto a target

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 the mathematical constant pi to determine the force observed by a hydrogen ion trapped in Earth's magnetic field.

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.
