@Setanta,
. AGI and all international geologic references use the terms "planetary geology" or even "Martian geology" to define the crustal dynamics "geophysics" "geochemistry" etc. MSL will be studying planetary geology, dont try to change what is already established.
If jeopardy meant this anwer to mean the actual STUDY of the surface , materials, structures, dynamics etc. of the planet, they would have been wrong. We dont use a made up prefix like areo, to precede areophysics or areochemistry, itd never be approved by the ed committees on publication.
(cf Glossary of Geology 6th ed) "Planetary geology"
