  1. Artificial gravity is a requirement.
    Or how about microgravity has been abusive.
    Or how about artificial gravity “might” allow people
    to live longer- could be a market for that.

    But anyhow artificial gravity is a requirement to explore Mars, and doing artificial gravity “correctly”
    could take a long time.
    What is the perfect radius for artificial Mars gravity to spin at?
    What is a good enough radius for artificial Mars gravity. What is the shortness radius for artificial Mars gravity which does more good than harm.
    Spinning fruit flies in short radius seems like spinning humans in short radius, though flies can have an even shorter radius because they are smaller.
    Does anyone know long term effect of spinning fruit flies in Earth gravity- I can’t imagine this not having some effect [which is bad for the fruit flies]. We don’t need to spin fruit flies or humans on Earth unless need to find the bad effects of spinning on Earth- which imagine there are some.
    I think we should start with about 10 meter radius in orbit. What effect of 10 meter spin at lunar gravity vs Mars gravity vs microgravity for period of 1 month.
    It possible there can found to be no significant difference. Good to know. It seems lunar artificial gravity would be easier to adjust to such a short radius, but it might not be much significant difference
    in adjusting Lunar vs Mars artificial gravity.
    After that it might be you want to try 20 meter radius- which with stick type artificial gravity, is sending another one up and connecting the two together.
    Or maybe need 60 meter radius, which indicate using a lot rope to connect them.
    And generally you want make station have low mass and strong enough to add radius.
    I would send a lot water and water which can be move or removed to make less massive.
    I would sent a station bare boned, but also designed to be improved/added to. Such add solar panels and/or environmental control system. I would send a can with with floors, and mostly water and 1 ton of compressed air. And be able add 1 ton by later bringing 1 ton of liquid air. And test it. Find out how to make them.

  2. Maybe there is no Oort cloud.
    “The Oort cloud sometimes called the Öpik–Oort cloud,first described in 1950 by the Dutch astronomer Jan Oort, is a theoretical concept of a cloud of predominantly icy planetesimals proposed to surround the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years).”

    Or no Sol Oort cloud, just Oort cloud everywhere.
