[edit] JPL's empirical formula and the Nov. 2007 Rosetta flyby
According to "Anomalous Orbital-Energy Changes Observed during Spacecraft Flybys of Earth" by John D. Anderson, James K. Campbell, John E. Ekelund, Jordan Ellis, and James F. Jordan[1], the authors made a prediction about the magnitude of the anomaly that Rosetta would experience during its November 13, 2007 flyby.
That was six months ago. By now, there should be some news about whether the predicion was accurate, but I haven't heard anything. Either way, it would be interesting. If you know something about this, please add it to the article.199.46.199.232 (talk) 21:46, 23 May 2008 (UTC)
[edit] Cassini
The number for Cassini is incorrect. Cassini measured no effect, and they looked for it too. --unsigned--
[edit] Comparison to Pioneer anomaly
"Satellites" should be "space probes" or "spacecrafts". Also it doesn't seem right to claim that the Pioneer Anomaly is "very similar" - Pioneer Anomaly means change in acceleration while FA means change in velocity. Also we have no idea about causes, so they may be completely unrelated. Mandevil (talk) 14:30, 5 March 2008 (UTC)
- How can you affect an object's velocity without affecting its acceleration? The two are, by definition, directly linked to each other.199.46.199.232 (talk) 21:46, 23 May 2008 (UTC)
[edit] Pure speculation on my part...
...But perhaps it has to do with the indications (recently mentioned on NOVA, on PBS) of a magnetic reversal soon to hit the planet within the next century. The magnetic field has been weakening, is the only extreme change I can see in Earth to cause a change in energy output and subsequent impact on incoming spacecraft. --Chr.K. 01:49, 12 November 2006 (UTC)
