Query: Expected velocity anomaly for the Earth flyby of Juno spacecraft on
  October 9, 2013   The so-called flyby anomaly is a yet unexplainable velocity jump measured at
several Earth flybys of spacecraft. Known physical effects could be excluded as
source of this anomaly. In order to model a possible new physical effect,
empirical equations were proposed by Busack (2007) and Anderson et al. (2007),
which gave quite good description of all measured anomalies. Some theories were
suggested deriving the Anderson formula or a similar one. The recent two Earth
flybys of the spacecraft Rosetta showed no measurable anomaly, although the
Anderson formula predicted distinct effects for both flybys. The Busack formula
predicted the null results, so the notion of a possibly correct formula or of
an error of the older measuring software was supported. The forthcoming Earth
flyby of Juno gives a good opportunity to decide this question or give rise to
enhanced theory, because the orbit parameters are very similar to earlier
flybys with notable effects. In this article, the flyby anomaly according to
the Busack equation will be predicted to be about -7mm/s in contrast to the
value after the Anderson equation and similar ones with distinct positive value
of the order of +6mm/s.
