I don't understand the problem, here. All data from NASA planetary missions are made public 1 year after they are taken. Here, you can go download them and use them for whatever you like at the Planetary Data System . There's a group of enthusiastic amateurs that use and interpret the raw data at UMSF , among other places. You're welcome to use these data and do science with them and publish them, scooping other scientists. Believe me, there's plenty of science left to be done in there.

Just the "pretty good depression", I'm afraid.
