Heat is source of ‘Pioneer Anomaly’

Submit on Wednesday, July 18th, 2012 22:56

The unexpected slowing of NASA’s Pioneer 10 and 11 spacecraft – the so-called “Pioneer Anomaly” – turns out to be due to the slight, but detectable effect of heat pushing back on the spacecraft, according to a recent paper. The heat emanates from electrical current flowing through instruments and the thermoelectric power supply. The results were published in the journal Physical Review Letters.
