Fly by anomalie
WebJul 6, 2015 · 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. WebJan 31, 2024 · The flyby anomaly is the unexpected variation of the asymptotic post-encounter velocity of a spacecraft with respect to the pre-encounter velocity as it performs a slingshot manoeuvre. This effect has been detected in, at least, six flybys of the Earth but it has not appeared in other recent flybys.

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. Numerically larger discrepancies (400–1000 m) have been observed …
