john anderson et al. continue to stay hot on the trail of various anomalies in physics, including the original pioneer spacecraft acceleration anomaly, where even after decades and dozens of independent studies, there is still no satisfactory explanation as to why spacecraft seem to be slowing down as they leave the solar system. another interesting effect that he describes in this paper is the "flyby anomaly," whereby spacecraft that pass within about 1000 miles of the earth experience a "forbidden" change in total orbital energy per unit mass. 0907.2469v2.pdf
