I agree with everything Shambles said about the subject. Humankind's ambitions reach far beyond a nearby inert lump of dust, and there's no point going back there for little return on investment. Our biggest issues are how to maximise our velocity, test out the feasibility of carbon-based humanoids surviving in long term zero gravity, and what the fuck do we do about it when we get there, wherever "there" is. The Moon is cool but it's a plaything when we're talking about the long term evolution of us monkeys
as a prime specimen of evolved simian magnificence, i feel it my duty to gently correct your enthusiastic yet somewhat misguided viewpoint on the moon
not sure who youre speaking for there but in reality our moon is anything but devoid of secrets. in fact its proximity belies the depth of mystery it still holds for the fields of planetary and primordial heliospheric cosmology
the moon you seem to have all figured out, is in actuality a fairly poorly understood celestial object, and when considering its proximity, that in itself is a not an insignificant oddity. for a start we still dont know how it came about, the collision model being only the latest in a long list of theories - but even taken as fact, the numbers involved in the random, by chance positioning where not only is the orbit not erratic, but a perfect circle -the only example of which we know - it is also rotationally synchronised and most incredibly of all.. though miniscule at a shade under 2,200mi in diameter to the sun's 860,000, the moon sits the unbelievably precise distance from the earth so that it exactly covers the sun's body while occluding nothing of the corona so that the overall effect to the observer on earth is of aesthetic perfection. being a sci-fi nerd youll be aware of asimov's genuine proficiency in astronomy independent of bookwriting...
. "there is no reason why the moon and the sun should fit so well.
It is the sheerest of coincidences, and only the Earth is among all the planets blessed in this fashion
..so it would seem asimov too understands the mystery that still shrouds this particular subject.
then of course you have the fact of our natural satellite's tremendous size relative to its parent planet - at around a quarter of the earths size and just over 1/80th of its mass. although pluto's charon is proportionally larger, that also is highly unusual, however due to the recent demotion of plutos planetary status, its arguable whether charon even qualifies as a true planetary satellite. either way, the earth's moon is incredibly large when compared to the vast vast majority of others known to astronomy. this alone makes the moon a noteworthy anomaly. when you add the fact the stratified composition is utterly bizarre and to all geological normality- 'inside out' inform - that is heavier elements at the surface with lighter ones below - this defies all known geological formation models.the well observed and documented anomalous 'fluorescent' lights on the moon surface witnessed through telescopes for hundreds of years and in fact so well known they were almost universally thought attributes of the moon's volcanic or tectonic activity - when the fact became established the moon had neither, the lights were suddenly and rapidly dropped from the discussion table.
and talking of anomalous stuff, the reason for the 'ringing like a bell' reverberations of the moon recorded at nasa when a rocket stage was jettisoned onto the surface.. for over four hours(!) ...has to this day never been adequately explained. we are able to view the moons of neighbouring planets in a higher resolution and consequently - more detail, than we can our very own, being too near to the longsighted orbital telescopes to be able to focus in on adequately. the veritable cornucopia however, of catalogued visual anomalies that have been observed suggests there are still many puzzles for us yet to decipher about our silent neighbour up there.
and of course, even the age of the moon is controversial, many reputable labs have dated moon rocks at a billion years older than the oldest such rocks observed on earth. if as appears, this is true - the collision theory goes out the window. which is why the dating is argued over so fanatically
the moon - like mars - displays these peculiar domed and 'bullseye' craters - evidence of massive electrical discharge scarring consistent with plasma physics and the electromagnetic model of the universe indicating perhaps the most easily accessible evidence for a tremendously cataclysmic period in our solar system that is still shrouded in darkness for us
not to mention the apparent 'bottomless' craters, anomalous shape and radically different elemental composition to the earth.. all deserving of further and in depth examination.
so as you can see, to discount the moon so readily as holding no more interest for mankind or science, is complete folly. it may well be the guardian of the most exciting of all, and we therefore disregard it at our peril
other than all that, you were spot on
