@anon82948922 might have a thing to say about Nikon 
Nothing at all. I only discuss worthwhile topics.
If we want to go to Mars we will probably need to build a staging base on the moon, because the moon has so much less gravity than earth. We might also need to build a few rudimentary roads on the moon if we want to use it as a staging base for launching rockets to Mars. Actually, all this is a pipe dream, because I don’t think we’ll be going to Mars anytime soon, and even if we did successfully land people on Mars that is still a long way from building a permanent colony there. Just guessing, I’d say that sometime around 2150 we will be able to build a self sustaining colony on Mars of fifty people. Just guessing.
