Einstein was wrong assuming that Gravity is caused by mass - Gravity is caused by a matter -antimatter energy potential by mass (quarks) in view to the quantum vacuum and vice versa.
In order to tell mass from energy in a quantized potential, an observer has to take into account the plane of the measurement. Gravity can be "translated" as an approximation into a classical view (classical physics), by applying the Euler Lagrangian Potential in view to the Euler identity (Geometry), for instance in a zero gravity flight: this is a local measurement for the observer.
Gravity is induced by the disassociation of space fields by matter fields and vice versa: a non-commutative gauge field potential - no one point particles but fields with dimensions.

There is a violation of the Einstein's Equivalence Principle (WEP (Weak Equivalence Principle) and Strong EP): when you quantize space-time at Planck Scale, you will detect that there is no time as such but energy scaling: the relativistic Quantum Vacuum can be compared to a perfect fluid (fluid dynamics) - there is an impact of the solar neutrino (- Oscillation-) to radiation decay rates and the fine structure constant Alpha.
Quote of Charles A. Laster, comments section: http://copaseticflow.blogspot.de/2013/05/solar-neutrinos-and-radioactive-decay.html: " I propose that the vacuum energy, treated as a perfect fluid, has a density governed by Relativity and the perfect fluid deviations of Einsteins Field Equations. Thus the density of the vacuum is higher closer to the sun, which affect to total energy level of an atom and hence its decay rate. In fact, any energy field, particle collisions, so on, can affect the value of the vacuum energy density within that region of space. Thus the vacuum energy truly is a quantum problem as currently calculated, giving predictions far from observation. This way of calculating the vacuum energy should give better results when compared with observation." Unquote
Neutrinos can have a mass (Koide formular) and the solar neutrino is very likely to oscillate.
We can look upon the wave function of the electron as a confined helical wave with a forward component (zig) and a reverse component (zag), that explains the zig-zag of the electron.
Neutrinos without any mass would be a left-handed spinor, comparable to the forward zig -wave of an electron. In case they have a tiny mass and are able to oscillate, it is possible that they interact with the vacuum field as part of a reverse zag wave.
A matter field with a heterogeneous composition ( e.g. a planet like Jupiter), is therefore likely to induce gravitational anomalies, and by that changing the requirements for a proper navigation (in the Jovian Belt).
The relativistic quantum vacuum changes its "density" according to the position of celestial bodies to each other (in the solar system, mostly perihelion/aphelion phases).
In order to give more evidence:
"It thus becomes apparent that the same type of shifting eﬀect as that noted
in  could conceivably occur, depending on the choice of gravitational potentials aﬀecting the VEP oscillations. Whereas before it was thought that
VEP oscillations were singly dependent on the product Φ∆fij, these results suggest that perhaps the value of the background potential Φ can indeed
be constrained by the resultant neutrino data. The ﬁgures presented here
immediately determine the observed energy spectrum of 8B neutrinos, and
many future neutrino observatories could detect these variations. As with
the results in [7, 14], it is found that the shapes of the probabilities are
strongly determined by the size of θ13, and small 13–angle oscillations provide a much more diverse spectrum of hP(νe → νe)i curves for diﬀerent
input values (in this case, the potential Φ).
Alternatively, what could also solve such a problem, should VEP be the
mechanism at work, is the detection and subsequent spectrum analysis of
extra–solar neutrinos from sources whose gravitational potential is known
to either great accuracy or reliability. Various papers have addressed the
detection of such high–energy intergalactic neutrinos subject to the VEP
Additionally, the discovery of a possible “gravitationally– induced quantum phase” was recently discussed in the literature . While the reference
treatment deals with MSW neutrinos which can possibly experience a phase
shift due to interactions with strong gravitational sources, it may be possible to extend the analogy to VEP neutrinos . Should such an extension
be possible, then it may be possible to determine the potential felt in the
vicinity of the Sun, since the gravitationally– induced quantum mechanical
phases of  would be functions of the source potential (hence the product
∆fijΦSource, and not just the product ∆fijΦSolarSystem. These conclusions
are as of yet unveriﬁed.
This is to be seen in view of the zig-zag (Zitterbewegung) of the electron and the oscillating neutrino that is supposed to have a mass:
‘In the zigzag picture of a Dirac particle, the vertices may be viewed as interactions with the (constant) Higgs field.’ Because the mass of the particle is acquired as it interacts with the constant mass vacuum field quanta at the vertices (some kind of mass-producing field, not necessarily any particular speculative Higgs boson, which has never been observed), it follows that the ‘coupling constant’ for the interaction must be different where the resultant particles are different in mass: the coupling per vertice (there are two vertices needed for each complete cycle of de Broglie wave oscillation as the particle moves in the zigzag motion) is a square root factor which apparently explains the Koide formula for leptons, including Carl Brannen’s modification for neutrino masses. This results from the decomposition of Dirac’s spinor into a 2-spinor form by Weyl in 1929, where one component of the spinor is left handed and the other right handed. A truly massless neutrino would be an entirely left-handed spinor, like just the zig part of the zigzag motion of an electron. But if they have a small mass an can change flavour (as observed for solar neutrinos), neutrinos must occasionally interact with a massive vacuum field and therefore have a very small zag component."
Flyby Anomaly, Credit: ArXivBlog
The (Earth) flyby anomaly is observed in non-closed, hyperbolic orbits.
Inertial mass is equivalent to gravitational mass, but according to gravitometrics and the relativistic quantum vacuum (also quantum fluctuations) , this may not always be true. Gravity is not a force but a non-commutative gauge field potential, the disassociation of space fields by matter fields. Is f=ma the same as F= G m1 m2 /r^2?
May be not, due to Quantum flucatuations and the relativistic quantum vacuum. Radiation decay rates are not a constant due to celestial bodies and the "density" of the relativistic quantum vacuum in the aphelion and perihelion phase. Energy behaves like a perfect liquid (superfluid), as CERN has confirmed recently. The quantum vacuum between two celestial bodies behaves like a bubble of air below water.
Gravity propagates at any speed, it is a space intrinsic entanglement. An object on Earth is not "falling down", this is just our observation: it recalculates the fields! Einstein's field equations just describe the effect of gravity in case the fields stay intact. By the Navier Stokes Existence and smoothness problem you may be able to derive a warp drive simulation.

The Road to Quantum Gravity and Violation of WEP, further reading
I have the impression, that time is including the vis viva potential (by Leibniz), hence in the 3 body problem, there is an INFINITE amount of equations. Quantum Gravity is literally: gravity (gauge field potential) by entangled (QM) space. Because gravity is the disassociation of space fields by matter fields.
Gravity is not a force inducing a pull (downwards on a huge matter field, a planet). Gravity is a residuing potential due to the disassociation of space fields by matter fields, a non-commutative gauge field potential.
Hence objects are not pulled but recalculate the fields instanteneously via space entangelment, relocalize objects.
There is no attraction, There is a residual gauge potential. There is no curved space and no distortion of space-time. Therefore gravity is not a force.
Everything in the universe is moving. A matter field in acceleration has to obey the laws of energy conservation.
Moreover, there is a violation of Einstein's Principle of Equivalence:
"The system gives the scientists the best opportunity yet to discover a violation of a concept called the Equivalence Principle. This principle states that the effect of gravity on a body does not depend on the nature or internal structure of that body.
"While Einstein's Theory of General Relativity has so far been confirmed by every experiment, it is not compatible with quantum theory. Because of that, physicists expect that it will break down under extreme conditions," Ransom explained. "This triple system of compact stars gives us a great opportunity to look for a violation of a specific form of the equivalence principle called the Strong Equivalence Principle," he added."
And now: ""By doing very high-precision timing of the pulses coming from the pulsar, we can test for such a deviation from the strong equivalence principle at a sensitivity several orders of magnitude greater than ever before available," said Ingrid Stairs of the University of British Columbia. "Finding a deviation from the Strong Equivalence Principle would indicate a breakdown of General Relativity and would point us toward a new, correct theory of gravity," she added."

Newton was wrong assigning gravity to a fundamental force of nature ... and have a look at the second law
Well, NASA and ESA didn't deliver the doppler deviation data by JUNO during the Earth flyby on October 9th, 2013. Moreover JUNO went into safe mode during the Government shut down and flyby manoever.
Hence no data, neither from ISON. The flyby anomaly is a test for gravimetrics, so lets wait for JUNO's data in the Jovian system. There should be a deviation within navigation in the Jovian system.
