Flyby anomaly
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. D. Anderson et al.: $${\displaystyle {\frac {dV}{V}}={\frac {2\omega _{\text{E}}R_{\text{E}}(\cos \varphi _{\text{i}}-\cos \varphi _{\text{o}})}{c}},}$$ See more Some missions designed to study gravity, such as MICROSCOPE and STEP, are designed to make extremely accurate gravity measurements and may shed some light on the … See more • J.

WebSep 1, 2008 · The flyby anomalies are unexplained velocity jumps of 3.9, −4.6, 13.5, −2, 1.8 and 0.02 mm s −1 observed near closest approach during the Earth flybys of six spacecraft. These flybys are modelled here using a theory that assumes that inertia is due to a form of Unruh radiation, and varies with acceleration due to a Hubble-scale Casimir effect.
