PIONEER ANOMALY EXPLAINED?
In the 1970s, the spacecrafts Pioneer 10
and 11 were launched for the exploration of the outer solar system.
Ever since J. C. Anderson (Jet Propulsion Laboratory, Pasadena,
California, USA) et al. in 1998 reported on a mysterious small acceleration
of Pioneer 10 and 11 of about 10-9 m/s2 toward the Sun, attempts
were made to explain this "anomaly". Was it "new physics" (modified general
relativity, vacuum fluctuations, dark energy, etc.)
or simply an effect overlooked in the analyses of the
experiments? You will find the answer in this
remarkable paper of B. Rievers and C. Lämmerzahl (ZARM, Bremen, Germany).
