This, I could see. If you make it reusable
Reusability is now seen as a wasteful distraction--more and more we are seeing systems scale up--to wit:
CHINA's HLLV concept:
From Craig Covault's home site
Some quotes from nasaspaceflight.com
"I don't see this as an Apollo architecture. The vehicle is planned to be significantly more powerful then Saturn V, the only reason you need something like that is if you're planning on building a base there."
From Phillip Clark, a great space researcher:
"For those of us who have followed the Chinese programme since the launch of Dongfanghong in April 1970, the current pace of the programme is almost supersonic! :-) China's programme has always progressed slowly, but this does not mean that they are not serious with their plans for programmes like piloted lunar missions and perhaps-serious plans for piloted missions beyond the Earth-Moon system."
"The Chinese always do what they promise in space, just not in the timescales that many people outside China are used to. Remember that we "oldies" grew up during the race to the Moon during the 1960s and the Chinese do not see themselves racing anyone anywhere at present."
SLS has 8 meter core.
CZ-9 has a 9 meter core.
Saturn V could put 118 t into LEO. CZ-9 can put 130 t into LEO.
Last but not least
from nasaspaceflight--"According to chinesedefense.com, the new launch structure currently under construction in Hainan will service rockets with LEO payloads in the 25 to 200 (!) ton range.
I see geoengineering by 2100. Reasons for it:
