It'll be interesting to see what the fallout of this will be. I have my own thoughts on the matter, but I'll hold my tongue, lest I burn any bridges behind me.
There's no getting around physics. Unless we switch to nuclear power or use fuels that spew out poisonous exhaust, we've pretty much reached the theoretical maximum lift limits of rockets. You can build bigger rockets, but they'll work on the same principles. And ultimately, the payload that gets into space is just a fraction of the mass of the the entire rocket with its fuel. Look at the size of the Saturn V that sent Apollo off to the moon, and all that came back from the trip was a little capsule. If we attempted the same trip today, the ratios wouldn't be much different. And then consider what it would take to get to Mars and back.
Back in the 60's, popular media led people to believe they could take vacations to the moon by the year 2000. We're just now getting to the point where private companies are on the verge of sending people into a sub-orbital flight at a $100K a seat.
Kinda' hard to believe that over 50 years into the "space age" and we've still got nothing better than a big, chemical explosion as a device to propel ourselves into space.
