Back to the Moon

Here’s a question that’s been dwelling on my mind for a while: if it was necessary for human beings to return to the Moon as soon as possible, how long would it take?

We know that there are various promises from different national space programmes to go (or return) to the moon in the next decade or so. From memory, NASA have it as part of their planned programme of activity to get to Mars, and both China and India have said it’s their aim to get astronauts there. (Russia and ESA have instead decided to concentrate on doing useful things in space and making money from them)

However, let’s say that we needed to get someone up there as quickly as possible. For the sake of the argument, let’s say some aliens come to visit and tell us that the secrets of cold fusion, faster than light space travel, matter transportation and unlimited rice pudding are all in a box that they’ve planted in a relatively easily accessible part of the Moon, just waiting for someone to come along and open it up – which, they state, has to be done in person by a human being.

So, we know we have a working plan to get men to the moon – build a Saturn V, stick an Apollo capsule with a human payload on top and then cross your fingers that it works – but how long would it take to build those from scratch? Are there current manufacturing plants – anywhere in the world – capable of doing that work, or would new ones need to be built?

Or would there be a quicker path through either cobbling something together from existing technologies? Could a Soyuz or Ariane be expanded to be able to push a payload far enough?

I’ve tried looking for information on this but – not surprisingly – little attention has been paid to the question of ‘how quickly could we get back to the moon if our new alien overlords required it?’ by serious people, so I’m throwing it open to the wisdom of the internets to see if anyone out there might have an inkling.

And, of course, there’s a great story to be told when the first human to walk on the moon in over 40 years gets to that box, solemnly opens it and finds a note saying ‘Wow! Never thought you’d fall for that one!’
