@Setanta,
OK, eventually Ill buy that. However, weve got these very rich guys who look on such activities as just aniother way of keeping "score"> SO WHY NOT LET EM??
The privateley funded space race with Musk an all the others sounds interesting as hell and its way more interesting than the canned feed from NASA.
Ultimately, as the time approaches a few BILLION YEARS from now, it will become an immediqte concern that will occupy all of the planets minds. I only hope that the dying of our sun will be a gradual ascent into Kelvin temperatures so that the population can acclimate to the concept of "We gotta get the hell outt here"
What with all the possible star deaths that could be possible in our neighborhood, the approach of Andromeda, an the real possibilities of instantaneous death via a gamma burst from some unknown source, we should be paying attention.
