Pioneer 10 and 11 appeared to decelerate 8.74×10⁻¹⁰ m/s² more than gravity alone could explain, sparking theories about modified physics and dark matter. Detailed thermal modeling revealed heat from radioisotope generators and electronics bouncing off the antenna dish created asymmetric radiation pressure pushing probes sunward.
