Flyby technique

A flyby technique involves sending a spacecraft on a narrow, carefully planned trajectory that passes close to a celestial object, like a planet or moon. This close approach allows the spacecraft to gather detailed data—such as images, atmospheric measurements, and gravitational information—without entering orbit. The technique is efficient for studying multiple targets with minimal fuel, enabling missions to gather valuable scientific insights while conserving resources. It’s commonly used in space exploration to quickly and effectively analyze planets, asteroids, or comets during high-speed passes.
