Pioneer Anomaly

[Telrad]

I have heard that Pioneer 10 and Pioneer 11 are affected by a residual sunward acceleration? What is causing this?

It accounts for all the anomaly it seems, not 66% as first supposed.

I wish I understood the Maths they used to calculate it, but far beyond me I'm afraid. A brain that adept, must keep one awake all night .

Thanks for the link George, that's interesting.

Cheers Ron. I read that the technological advance in the instruments being used to calculate the distance of both the Pioneer spacecraft may account for the anomaly?
