Space Science (any branch of physical and even psycho and medical sciences) is the highest of the fields, it is in a sense the true "unifying
field". That is, all sciences are necessary to have manned space flight, rudamentary medicine does not need theoretical physics for instance. Basic
physics doesn't need an understanding of quantum mechanics or even theoretical math.
But as you progress in those sciences, the fields tend to become more unified, theoretical physics and chemistry are not too different in some
respects. Biology uses both, Geology is all those combined into understanding the earth. Theoretical Maths is just about the only field I can think
of that exists in of itself with little need for practical application.
So since space sciences for manned space flight requires all of this, there is no "website" that can clue you in to anything. On my computer at
home (obviously I'm not home) I have a bookmarked webpage that comprises the entire photo-journal of Apollo. It also has the entire data series
collected, and full scientific journals of the data from the Apollo missions.
It is mind-blowingly large and complicated, and that is the Space Program. If you want to get informed I suggest you continue in a path of a physical
science or math or both since they are so related and from there Ph.D in a field or two that are more useful to NASA (Physics, Planetary Geology,
Astro-physics...so on) and then you'll really be able to get informed on all this stuff.
If you just check out sites that say "this or that" it's just really basic information.
Everyone here I guess posted some good site for using terminology, but I doubt many here, or anyone here can truly do the work to come to the
conclusions that you could find on fore-mentioned Apollo journals. When I get home and find time I'll post that site here, and you can thumb through
that for a while untilt he categorization of the pictures alone makes your brain numb. Then you can go to Apollo 17 and look up the data sets because
Apollo 17 was the most comprehensive of the geological efforts on the Moon and it's extremely extensive.
They did more than walk around up there, oh that's sure as hell.
Anyway, I just don't believe you can become more informed from websites, you're just going to have to go through 11 more years of education to begin
to be informed on this stuff.
