@all dicussions of Saturn V
My point was not that the new ship is an EXACT or even visually similar large copy of the old Apollo craft, but that after 40 years there has been no significant step forward in launch technology, we are still talking about solid rocket boosters and 'old-fashioned' liquid fuel engines.
NASA is suffering for the cancellation of such projects as VentureStar which was working, for example, on an aerospike engine that was more efficient than the 60's technology still used by ESA and NASA on Arianne and the Space Shuttle.
What is the point of going back to the moon if it isn't going to drive the development of safe, reliable and cheaper (in the long term) spacecraft? There are three different requirements, demanding three different craft:
1. Earth (high gravity) to orbit and back making optimal use of the fact that we can build specialised launch facilities be it long runways or launch pads.
2. Earth orbit to Moon/Mars/ano orbit. No real gravity concerns so a ship designed just to go between orbits will be light and simple.
3. Orbit to unprepared landing site and back for landing on the moon (or wherever) - different challenges again to earth take-off and landing.
Why try and do all three at the same time? Lets resurrect VentureStar or something similar to give cheaper and safer into-orbit technology, we can then design, build and test intra-orbit craft and work on the hardest bit which is a reliable and safe, reusable craft for the moon landing.
Anything that is based on non-reusable technology is a complete waste of time and money and doesn't take the human race any closer to more regularised space travel.
Paris, because even she could arrive at this conclusion...
