orbital mechanics - Is the Flyby Anomaly still a thing?
WebFeb 14, 2024 · The Flyby anomaly is characterized as a very tiny difference between the measured change in velocity of a spacecraft after executing a flyby maneuver, and the calculated change, based on an exhaustively thorough modeling of all of the components to the gravitational field as well as all other non-gravitational forces have been modeled. The flyby anomaly is a discrepancy between current scientific models and the actual increase in speed (i.e. increase in kinetic energy) observed during a planetary flyby (usually of Earth) by a spacecraft. In multiple cases, spacecraft have been observed to gain greater speed than scientists had … See more Gravitational assists are valuable techniques for Solar System exploration. Because the success of such flyby maneuvers depends on the exact geometry of the trajectory, the position and velocity of a … See more An empirical equation for the anomalous flyby velocity change was proposed in 2008 by J.
