When was the first gravitational map of a planet or moon made by measurements from space?

I'm guessing it was a map of Earth, since that's the closest planet to us,[citation needed] but for all I've been able to learn, we might have already mapped it sufficiently from the ground.


It was the Earth, of course. As early as 1964, scientists realized that the non-Keplerian orbits satellites gave a picture of the Earth's interior. For example, see S. K. Runcorn, "Satellite gravity measurements and a laminar viscous flow model of the earth's mantle," Journal of Geophysical Research 69.20 (1964): 4389-4394.
