A strange anomaly in the movement of the Pioneer probes may have been explained

At optical frequencies a radiated power of 300Mw is required to produce a thrust of 1 n, I would expect the outer casing of the electronics package to have a temperature of about 50K.
This would produce a very small thrust compared with that produced by the radioactive power source for which allowance has already been made.

"1 part in 10^-10 ms^-2"?  I think you mean "1 part in 10^10" (i.e., +10 not -10, and no units)
