WebFlyby anomaly occurs when a spacecraft taking advantage of the gravitational boost provided by an Earth flyby experiences a tiny extra boost in velocity. The anomaly was first observed in 1990 when NASA’s Galileo spacecraft velocity jumped by about 4 mm/s more than expected due to an Earth flyby en route to Jupiter. 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.
