Re: Something doesn't add up

Welcome to the big elephant in rocketry. To go further up costs you more, you need more stages, which weigh more, which in turn needs more thrust which in turn weighs more, which in turn... Ask the Saturn V engineers how much fun they had trying to get things right just to get to the bloody moon with a piece of metal of which half was left there as rubbish...

This is why there is a suggestion that interplanetary ships should be built/assembled in space, where it's possible to get around this pesky problem of getting off the surface of the planet first (fighting against that damn 9.8m/sec2 reduction and the air resistance of the different *spheres) which costs an awful lot in energy.
