The Pioneer anomaly
Interesting story on the Pioneer spacecraft (numbers 10 and 11, launched 30 years ago), no longer being where they’re supposed to be. Through very precise and careful calculations of all the effects of gravity, solar wind and onboard thrust, scientists say the craft “should be” about 400,000km (the distance from Earth to the moon) from where they are now.
While the most likely cause is simply an unexpected on-board effect, such as the ships giving off extra heat or gas (and kudos to the reporter for making this clear in the article, and not sensationalising things!) it is possible that something more interesting is in play. Possibilities include dark matter in our solar system, or even an unkown feature of gravity. The European Space Agency may well fund a “mission to explore the Pioneer anomaly”. Because even though the explanation is likely to be mundane, if it’s not then it’s a big thing for physics! It won’t be till 2015, though - so don’t get your hopes up yet.

By using the light dynamics, the radiation pressure for any reflective surface can be derived. By using the same approach the light rocket engine thrust equation can be derived.

Since the gravitomagnetic force component Fg is not radial, it exerts a moment of force on the two-body system. This moment of force is negative during half cycle A and positive during half cycle B. This moment of force induces a negative rate of change of momentum known as torque during half cycle A and positive one during half cycle B. Thus an alternating torque, hence an alternating rate of change of angular momentum of the two-body system. There is no conservation of angular momentum as stated by the Newton law. The positive moment of force is always greater than the negative one. This explains the mercury perihelion advance. For more details see gravitational waves radiation www.gravitomagnetism.com

By using relativity, gravity waves have quantitatively been determined during the solar eclipse. The gravity waves are induce at a supersonic speed (1000m/s), they induce gravitomotive force g.m.f. in gases and liquids, thereby creating masse currents which is converted into sound waves; they also induce electromotive force e.m.f. in electric conductors, plasma, ionosphere and metals thereby creating electric currents.
Since the quasi stationary orthodox gravity shield theories do not offer a global and coherent explanation concerning gravity perturbations, can there be a physical science work of more importance than obtaining an understanding of these perturbations and seeking interaction with the remote forces of gravity?
The facts are there, the facts remain the keystone in which the stability of a theory must be tested.

Dear Sir,
I have now solved the pioneer anomaly and also other 5 cosmological blunders of the last 85 years, see the summary page 8, new Newton law page 1, www.gravitomagnetism.com
