Description:
The predicted general relativistic effect of solar gravity on the round-trip times of electromagnetic signals traveling between earth and Mars has been verified by means of radio ranging to the Viking spacecraft. The ranging measurements were found to be consistent with the predicted increases of up to 200 microsec in the travel times of the signals to within the estimated uncertainty of 0.2%.
