Hellings, R.W., P.J. Adams, J.D. Anderson, M.S. Keesey, E.L. Lau, E.M. Standish, V.M. Canuto, and I. Goldman, 1983: Experimental test of the variability of G using Viking Lander ranging data. Phys. Rev. Lett., 51, 1609-1612, doi:10.1103/PhysRevLett.51.1609.

Results are presented from the analysis of solar system astrometric data, notably the range data to the Viking landers on Mars. A least-squares fit of the parameters of the solar system model to these data limits a simple time variation in the effective Newtonian gravitational constant to (0.2±0.4)×10-11 /yr and a rate of drift of atomic clocks relative to the implicit clock of relativistic dynamics to (0.1±0.8)×10-11 /yr. The error limits quoted are the result of uncertainties in the masses of the asteroids.
