Flyby anomaly
http://www.space-time.info/pioneer/flybyanom.html WebThe flyby anomaly is an unexpected energy increase during Earth-flybys of spacecraft. This anomaly has been observed as shifts in the S-band and X-band doppler and ranging telemetry. Taken together it causes a significant unaccounted velocity increase of up to 13 mm/s during flybys.

WebShort description: Unexplained observed excessive energy during Earth flybys of spacecraft 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. WebJul 6, 2015 · 21. Whilst the main factors involved in transferring energy to space craft during a flyby are well known, I believe this is a reference to several observed anomalies that have occurred to various space probes, covering everything from the early Pioneer probes to the much more recent Rosetta probe. The researchers looked at five deep-space ...
WebThe flyby anomaly is a discrepancy between current scientific models and the actual increase in speed observed during a planetary flyby by a spacecraft. In multiple cases, spacecraft have been observed to gain greater speed than scientists had predicted, but thus far no convincing explanation has been found. WebIndeed, no anomaly was observed during the 2009 Rosetta flyby. This doesn't contradict Anderson's equation, which predicted an anomaly smaller than 1mm/s. Lacking the data …
WebMay 15, 2024 · Even more intriguing is the flyby anomaly, i. e., the unexplained difference among the post-encounter and the pre-encounter Doppler residuals of a spacecraft in a gravity assist manoeuver around the Earth (Anderson et al., 2008). The first detection of the effect occurred during the first Galileo flyby of the Earth on December, 8th, 1990.
