Spacestation Question

  1. Jan 15, 2010 #1
    I have a question:
    What would be the feasability of directing our old space junk towards the moon?
    Have it all deposited in a certain area.(junkyard) future astronauts living there could build and repair there.
    Spacestation and hubble, put rockets on it and guide to soft landing?
    Would this not be cheaper than launching completely from earth.
    Spacestation too large. disassemble and land it in smaller sections, reassemble it there?

    Just a question: Thoughts anybody?

    Which space junk are you referring to? And a better question (since you clearly dont care about the amount of energy it will require to deliver that junk 380,000+ km away) - why not send it to the Sun so it burns up clean?

    What is the logic of sending junk to be reused later? In addition, you now need more energy just to slow down this junk so it doesn't crash into the Moon but rather lands gently

    Would take same amount of energy (if not more) to launch from Earth to Moon, slow down, land and then launch personnel there to assemble there. Then you have to build a moon station in 1/6 the gravity of Earth, find oxygen source (sure Moon is 42% oxygen but how are you going to harness that?), plus water, food, and shield them from micrometeorites and radiation, not to mention insane temperature fluctuations.

    Why? It will take more energy and reverse a progress that was already done. Not to mention money that we dont have. Not to mention we have several treaties about other planets and the moon - we can't build any military installations on the Moon, and we can't "claim" any territory of the Moon for our own

    I think its dangerous to be on a planet or moon that does not have an atmosphere. For that reason the Moon is just not sustainable for humans. Planet Mars could be a great remote outpost

    Mars atmosphere:
    95.32% carbon dioxide
    2.7% nitrogen
    1.6% argon
    0.13% oxygen
    0.07% carbon monoxide
    0.03% water vapor
    trace amounts of neon, krypton, xenon, ozone, methane

    I don't know but that looks almost perfect for plants, with only exception that you also need water. If you can find water or master process of making water, this is the next best place for humans
