Invisible Force Challenge
DCMP is transitioning to player-based accessibility features, allowing for customization of captions, description, language, and playback speed. Learn more about these features and how they can be beneficial in an educational setting.
Learn MoreTo change a spacecraft's speed and direction, NASA engineers use a planet's or moon's gravity, a process called a "gravity assist." In this video, students design and build systems that use magnets to control the speed and direction of a rolling ball. As they build their systems, they use the engineering design process, apply a variety of science concepts, and learn how NASA spacecraft use gravity to help them explore the solar system. Part of the "Design Squad Nation" series.
