Going where no one has gone before

My friend Joey was asking me what I thought of the space program. Was I for it, or did I think it was a waste of money that could be put to better use here on planet Earth. I told him I was very much for it, but I have to say, I'm not that enthusiastic about all this exploration of the planet Mars.

Curiosity has now been deposited safely on the planet's surface -- certainly no mean accomplish-ment. Imagine: the NASA folk were able to build and direct by remote control a space ship that would travel over 100 million miles and then gently deposit the latest rover on the surface of another planet. Very impressive indeed.

But...for what purpose? To see if they can find more and better evidence that there may have been life on that planet at one time. But I can't see the point in that. If there was any form of life in some distant past, it was certainly in the microbial category. Finding evidence of that is hardly going to answer the question that they keep mentioning in the newscasts these days: are we alone? We already know we are alone in our own solar system, as far as life forms in any way approaching our own go. We have to look way, way beyond our own backyard, so to speak, to find the answer to that big, looming question. And I personally think that is what we should be spending those billions of dollars, and all that scientific know-how, on: developing ways to get beyond our solar system. That and figuring out ways to colonize those foreign bodies within our solar system where humans could possibly live, in a controlled environment, since our own planet is rapidly becoming too crowded.

After all, humans have always moved on when the area where they were became too crowded -- not enough resources to support their numbers -- have always explored what was over that rise, beyond those mountains, across that sea. I feel space exploration is just an extension of that, though it is far more difficult, and expensive, than crossing those mountains or that sea. But I don't think we should be wasting our time trying to figure out if there was some primitive form of life on Mars -- or anywhere else -- once upon a time. What is the place like now? What would it take for humans to be able to land on these places, and spend any time on them?

President Obama's space exploration policy, which he outlined in 2008, includes the statement that he "endorses the goal of sending human missions to the Moon by 2020, as a precursor in an orderly progression to missions to more distant destinations, including Mars." So do I. Let's get on with it.
