MTd2

My first parameter is the weight and then using this weight, 1MT, set the best speed. It is like giving you a lot of sand and make you build a sand castle. Saturn V weighted 3k tons, it is the heaviest. So, I take it as a basis for construction. So, I have to use at least 334 of these. Apollos space craft weighted around 50 tons: http://www.braeunig.us/space/specs/apollo.htm. So you'd need 60 apollo rockets to push another Apollo rocket. If we use a first layer of 300 of these, we would have a second layer of 5 rockets. That's short of 29 of the minimum for 1MT. So, it's better than to surpass 1MT slightly, using a further 60 in the first layer, so we have 6 apollo rockets in the second layer. In the end, that's 300tons of spare cargo in the end. - - - Updated - - - Now, that is a massive slow down. Is there a way to turn off effects, like the rocket fire and smoke?

I am indeed thinking about the feasibility. It seems there is a slowdown already with Saturn V alone.

No nuclear part! I want to only use existing stuff, except for struts. I'd also not to use no ion drive. By most efficient, I mean, with 1MTon of stuff, achieving the biggest delta V for that given structure using the less fuel. The last part non propelled is only the default reentry capusule.

I was thinking of building one, the most efficient in achieving the highest V as possible. But all using known technology. 1MT mean 300 Saturn V. So, I'd use sets of saturn V and modules to build up. What are your suggestions?
