Have any satelites mapped the thermodynamics of point in an orbit of a planet other than earth before?

Question

Most satelites I hear of are sent out to space, have any been put in a planet orbit maybe at a stationary point to map the time dependent thermodynamics of the orbit or at that point in the orbit of a planet other than earth? What is easiest possibility?

Answer 1

A thermal map of Mars was made by the Mars Global Surveyor ( http://tes.asu.edu/ ).

And the Venus Express spacecraft has done thermal mapping of that planet.

Answer 2

Hi The only stable point that are stationary are the Lagrange points. There are objects in Trojan orbits that take a strange path but what you seem to want to know is whether or not we have ever put satellites in any on these orbits. Yes we have, but not for the reason you specify.
