Very interesting story on SPACE.com regarding currently unexplained anomalies in the velocities of spacecraft after their Earth flybys.

http://www.space.com/scienceastronomy/0802...ft-anomaly.html

Perhaps the twisting of spacetime induced by Earth's rotation could be gently altering the spacecraft's velocity.

In any case its pretty cool to have an unexplained force meddling with our best laid plans.
