Astronomers were able to detect an anomaly in Earth orbit. The four spacecraft flying around the Earth, showed an unusual change in velocity. A similar case has already been observed for about ten years ago with the spacecraft "Pioneer."

Once on the outside of the solar system, apparatus, “Pioneer 10″ and “Pioneer 11″ suddenly did not get the calculations predicted acceleration directed towards the Sun. Scientists have put forward a lot of theories – and a leak of fuel gas from fuel tanks, and almost did not propose to reconsider the whole theory of gravity – a simple answer and some explanations have been found.
Currently, NASA has been studying the anomalies, which have undergone the action of “Pioneers”, but an astronomer John Anderson, for the first time experienced the very same “Pioneer” anomaly, turned his attention to another. It turned out that when the gravitational maneuvers near planets spacecraft also receive, albeit small, but quite a substantial kinetic energy is not confined to the preliminary calculations.
Scientists working with Andersen, have collected quite an impressive “anomalous” dossier. At various times, performing maneuvers near the Earth using its gravitational field, spacecraft “Galileo” (mission to Jupiter), NEAR (the asteroid Eros), “Rosetta” (the comet Churov-Gerasimenko), “Cassini” (Saturn) experienced the effect of the anomaly.
Anderson and his research team also studied the history of flight of the spacecraft “Messenger”, which took place in almost identical conditions, but no anomalies were found. “Messenger” closer to Earth at 31 degrees north latitude and moved away at about 32 degrees south latitude. Apparently, at the expense of such a symmetry about the equator speed change apparatus was negligible. Perhaps that is why no deviations to identify and failed. These findings Andersen made based on history of flight probe NEAR, which, like many other devices, which showed abnormal changes in speed, flight path was not symmetric about the equator. In NEAR change in velocity with distance from the Earth was at 13 millimeters per second is greater than originally calculated.
Perhaps the anomalies of near-and anomaly “Pioneer” have a common origin. On their similarity says at least the fact that the “Pioneers” have shown abnormalities in orbit around the sun and other devices – around the Earth. Plus, a similar change in velocity were recorded and near other planets. Under assumptions of scientists from NASA, this similarity is explained by one mechanism, but how – remains a mystery. Investigations are continuing anomalies. In particular, it will analyze the data on changes in the speed of the spacecraft “Rosetta”, which should come closer to Earth, November 13, 2008.
