The Deep Space Network, NASA’s international collection of giant radio antennas used to communicate with spacecraft at the Moon and beyond, helps scientists and engineers use gravity and radio science experiments to learn more about our planetary neighborhood. Learn how scientists and engineers can infer a spacecraft’s location and how fast it’s going by measuring changes in the spacecraft’s radio signal frequency.
Viewers also get a basic overview of gravity and the Doppler effect.
