There is talk of within the decade we will have men walking the surface of Mars. I wonder on the prudence of the capital expenditures necessary to finance such an endeavor when as a world we are insufficiently addressing the basic needs of its people. Furthermore should we be focusing our attention on the stars when there is so much we do not understand about our own planet and the mysteries just beneath the surface of our oceans. Just a thought…. We are making some fantastic advances in wave pump generators producing electrical power from the simple action of the waves. That is the advancements that most excite me, the utilizing of the abundance available right here on our planet in green healthy technologies that will benefit mankind for generations to come! Then we can expand past the moons rings.
