Try to know the usefulness of those successful missions.

You observe a binary system with a period of 32 years and an average separation of 16 AU. Star A is 12 AU away from the center of mass, and star B is 4 AU away from the center of mass. What is the total mass of this system, and what are the individual masses of star A and star B? Give your answer in solar masses.

I think they mean observations recorded by satellites or images taken by them (e.g. MESSENGER, Venera 13/14). This might not be specific to "satellite measurements and imagery," but it might include a certain spacecraft measuring the percentages of a certain element in the atmosphere, for example.
