From there, the ribbon will be deployed downward to earth as the counterweight moves out beyond GEO. The starting plan calls for a 'starter' ribbon which we're currently estimating is going to require between 5 and 8 launches of the Falcon 9 S9 or Saturn V sized launches. With a much larger launch payload, we can either send a wider/higher capacaty 'starter' or a little bit lower GPa material within the timeframe necessary to make it a viable commercial venture. (btw, thanks N.S., you're purchase is appreciated.) _________________ 10 years after everyone stops laughing. - Sir A. C.

Build CaLV first--then Sea Dragon. Then SE. THAT is how you open up space.

Personally, I think CaLV is not Heavy enough. It took a Saturn V to put just 2 men on the Moon for a couple of days at most. CaLV with about the same payload, wouldn't achieve much more in one launch, hence the CLV. To establish a useful presence, a lot more will be needed. That means many hundreds of EELV's, or dozens of HLV's. We really need a VHLV (Very Heavy Launch Vehicle) 400+ tons. Well, there is theSea Dragon. Is 450 mT to LEO good enough?

That is what I was hinting at. Although my preference is a very large, 'one time' Orion. Put about 100,000 mT in orbit in one go, then use the 'empty' vehicle to cruise around the solar system, and as a work horse for big jobs like moving small ice moons. http://www.astronautix.com/lvs/orietary.htm

A single, once-off launch would only increase the radioactive pollution in the Earth's atmosphere by about 1%. But I'll settle for Sea Dragon.
