"Budget."

(or, at least, this is what I imagine the answer is.)

Apollo had some major issues with moon dust and such - maintaining a sterile environment is a different, if overlapping skillset with maintaining an environment within a vacuum.

That said, there's all the NBC preparedness of the military, and e.g. the medical response to outbreaks and quarantines - even if "don't enter the quarantined area" is rule 1.

But hey, maybe Robots could be an option at some point. Still - do you fund the expedition that requires expensive, custom, bespoke explorer-bots (because there hasn't been much of a market for those for mass production to drive down costs or standardize things) or do you fund the expedition where you can send a few students for school credit?

You'd die of heatstroke tromping around the jungle in an environmental suit.

I assume the answer is: cost. It's very expensive to fully isolate yourself from your surrounding environment both for the sake of exploring but also for camping. I would imagine there's not a lot of funding for this sort of research, if only because it doesn't seem to have much intrinsic value.
