Something strange is happening in the outer reaches of our solar system. The Pioneer 10 and 11 spacecraft are not where they are supposed to be. These missions, launched in 1972 and 1973, have covered hundreds of millions of kilometers, heading toward the edge of our solar system. But something is holding them back. Each year, they fall behind in their projected travel by about 5,000 kilometers (3,000 miles).
Jet Propulsion Laboratory scientist John Anderson and his colleagues have been searching for an explanation since 1980. But as of yet, they have found nothing conclusive; no spacecraft behavior or previously unknown property of the outer solar system can explain the deceleration of the Pioneer spacecraft. Scientists are being forced to consider the unthinkable: something may be wrong with our understanding of the laws of physics. An important line of inquiry will be to study mounds of Doppler (velocity) data and spacecraft status data (like temperatures) that have been unavailable to researchers—but that is about to change.

Ok so they cannot confirm the same anomaly on either of the Voyager craft because the Voyager craft seem to be thruster stabilised and that supposedly complicates the effect of the solar winds.
Having said that, this is NOT happening on either of the Voyager craft, and infact V2 is around 10 AU further out than P10.
Is there something inherently different about the front P10 is advancing toward?How is wish P11 was still active!! Data from P11 would answer most of these Qs straight off!!
For example, the spiral arms of a galaxy must carry the electric current that lights the stars.
