Gravity assists use the gravitational pull of a celestial body, like a planet or moon, to alter the speed and direction of a spacecraft traveling through space. By flying close to these bodies and entering their gravitational fields, a spacecraft can gain or lose velocity without expending fuel, allowing it to reach destinations more efficiently and achieve greater speeds. This technique has been used in many space missions, such as NASA's Voyager and Cassini spacecraft.
