Smith Dear David A. Smith Thank you for your comments and the links which I will study. The Pioneer 10 and Pioneer 11 have an unexplained very small *deceleration* which is the same as a *negative acceleration* as in my calculation. So I think that the direction is not wrong? What are the measured magnitudes of the velocities of the Pioneer Probes? Have you knowledge about that? Best regards Louis Nielsen Denmark
