Should we Colonize the Moon or Mars first?

  1. May 12, 2015 #1
    I have reasons that have convinced me that Mars would be better, but I want to know what everybody else thinks.

    Why colonize either at this moment in history? Or do you mean in a few centuries?

    Why? And please post peer reviewed scientific published papers only as your sources.

    And please, no one jumping in with personal opinions.

    It would be vastly easier and more beneficial to colonise Earth more. The deserts, the ice caps, the ocean surfaces and floors, the mountains, the tundra and even underground. Figure out how to do all that whilst maintaining the biosphere and you might have some spin off technologies that would help space enthusiasts go and live elsewhere.

    I see no reason why we would colonize either, as we understand the meaning of the word. Will we ever establish a long-term/permanent base for the purpose of scientific research, or providing mission resources, on either the moon or Mars, or both? Probably. Will we ever send settlers to the moon or Mars to establish political control, a.k.a. "colonize?" Not in the foreseeable future.

    NASA is already considering using the moon to generate fuel and predeploy those, and other resources, for missions to Mars and other destinations.

    I'm not sure we have enough data to answer the question.

    The human body suffers some serious problems in long term microgravity. We don't know what effects simply low gravity will have or how we could resolve them. It might be that low gravity combined with proper exercise (possibly under artificial gravity) would solve these issues, but we just don't know what level of low gravity is healthy. It may be that either or both are available for colonization. Or not.

    Logically, I think we'd have to set up some kind of forward base on the moon before we could maintain any kind of consistent transport of supply to mars.

    Agreed. The moon is much easier to take off from and return to Earth. If there was a disaster on a moon base the scientists and other staff cod get back to the safety of Earth within days.

    Why is that? Don’t you think we’d have to get the supplies out of Earth’s gravity well first in either case? Then we are going to have to re-launch them from the moon?

    For goods made on Earth, that is true. But most of the goods (by mass anyway) might be made on the moon. Fuel, water, and radiation shielding could all be made on the moon. Possibly carbon and other biologicals could allow hydroponics inputs as well.

    They could be placed into orbit with some sort of quasi-reactionless drive cheaply due to the lower gravity and lack of atmosphere.

    Actually, fuel, oxygen, water, and other resources can be produced on the moon and supplied to a spacecraft in space at a fraction of the cost it would cost to launch the same resources from Earth. That would also reduce the costs of launching from Earth as well, since those resources will not have be launched from Earth.

    Any way do someone know what experts think between moon or mars for colonizing?

    It's an MIT study, close enough. I also allowed the NASA paper.

    It's not what you asked for:

    See my reply above, in GD, if the papers are from valid, known sources, I'll allow them, I just don't want any mass media or pop-sci stuff.

    Then I would like you to post the original source instead of an article saying what the source says.

    Shall I delete the NASA paper also since it's posted on a blog?
