A Prosaic Explanation for the Anomalous Accelerations Seen in Distant Spacecraft
Anderson, et al. have recently reported the discovery of an apparent anomalous, weak, long-range acceleration in the Pioneer 10/11 and Ulysses spacecraft. I believe that this result can be explained by non-isotropic radiative cooling of the spacecraft electronics through passive radiators on the spacecraft surface. These radiators are preferentially placed on the anti-solar side of the spacecra...
متن کاملDoes PIONEER measure local spacetime expansion?
There is a longstanding mystery connected with the radiotracking of distant interplanetary spaceprobes like ULYSSES, Galileo and especially the two NASA probes PIONEER 10 and 11. Comparing radiosignals outgoing from the earth to the probe and ingoing again from the probes do show anomalous frequency shifts which up to now have been explained as caused by anomalous non-Newtonian decelerations of...
متن کاملThe Pioneer anomalous acceleration: a measurement of the cosmological constant at the scale of the solar system
An anomalous constant acceleration of (8.7 ± 1.3) × 10 cm.s directed toward the Sun has been discovered by Anderson et al. in the motion of the Pioneer 10/11 and Galileo spacecrafts. In parallel, the WMAP results have definitively established the existence of a cosmological constant Λ = 1/L2U , and therefore of an invariant cosmic length-scale LU = 2.85 ± 0.25 Mpc. We show that the existence of...
متن کاملSe p 20 09 A possible scenario of the Pioneer anomaly in the framework of Finsler geometry
The weak field approximation of geodesics in Randers-Finsler space is investigated. We show that a Finsler structure of Randers space corresponds to the constant and sunward anomalous acceleration demonstrated by the Pioneer 10 and 11 data. The additional term in the geodesic equation acts as “electric force”, which provides the anomalous acceleration. PACS numbers: 02.40.-k, 04.50.Kd, 95.10.Ce...
