View Full Version : A Possible Answer to Flyby Anomalies

Strange things are happening to our robotic space*explorers. Also known as the "Pioneer effect"*(the unexpected and sudden alterations to Pioneer 10 and Pioneer 11 trajectories measured as they continue their journey into the outer solar system), similar anomalies are*being seen*in flybys by modern space probes. Earth flybys by Galileo, Rosetta, NEAR and Cassini have all [...]

That's interesting, and potentially testable with not much additional budget applied to some current and upcoming projects.

I was aware of the Galileo and and Rosetta anomalies, but not NEAR and Cassini?...rather useful information for those of us predicting such events. We are still waiting on New Horizons and Messenger (Messenger is predicted to have experienced slightly less gravitational braking during the Venus pass).

...and the explanation cited in this thread does not address why these deltas seem to be related to gravitational assists.
