    What about all those microbes we live symbiotically.
    Maybe they won't take kindly to space exploration and Mars.
    One thing they do is keep our immune system tuned up.
    Sterile environments provoke "cancer" and general illness.
    Cancers prevented by Immuno Surveillance. Poor immune system and . . .


    Skin health
    Digestion.
    etc.

    I was thinking about the terrible mediocrity. Someone posted that earth is the only planet with chocolate. So much would be missing in our diets.

    Hmm, more like putting on weighted clothing designed for rational distribution.

    There might be more to it than that, as you can't add weight to your various organs.

    I think we have MANY years to worry about this. My bet is that space based manufacturing will assemble stuff sent from Earth. After that, we could start using material from asteroids, with late reports suggesting that many are simply rubble piles that could be "mined" by scooping up stuff.

    That seems a little skimpy on the requirements for being considered a colony.

    Just shows how far we have to go before humans can safely go where no man has gone before...

    Are you referring to Hillary Rodham ?

    I think Bill went there once and only once. back in 1979.

    No but obviously you are already there.

    We know the effects of centripetal force [not centrifugal force, that is a pseudo force]. It is called gravity. While the engineering needs to be explored, Einstein assures us that biologically, we won't know the difference. However, if the gravity is reduced from 1 g, that is another matter.

    Obvious you didn't understand.

    The last time Hillary Clinton had coitus with a man was supposedly around 1979 when Chelsea Clinton was conceived.

    No, I'm pretty sure that Einstein assures us that we won't know the difference between gravity and a constant acceleration that matches the pull of gravity. A rotating cylinder, creates centrifugal force that pushes against the central axis, like swinging a bolo. The force pushing against the outer edge of the cylinder may feel like gravity, but honestly we don't know what the effects on the human body are because the force won't be equal. It will be stronger at your feet than it will be around your head. So how does that effect your inner ear? your circulatory system? We need to build a rotating space station to find out. It may turn out that humans can't live in those circumstances.

    I understood the physics about 45 years ago. ;) But if you say so. Given that you don't know the difference between centripetal and centrifugal forces [first quarter physics 101], I'll stick with what I know.

    Even time dilation is the same due to centripetal forces, and gravitational fields having the same force magnitude and direction.

    OK I admit I don't understand what time dilation has to due with centrifugal (or as you say, centripetal) force. So are you saying I'm wrong, and a spinning cylinder with be exactly the same as gravity or acceleration, and there will be no difference in pull or g from the feet to the head? They'll be exactly the same? So no inner ear or circulatory issues?

    Saw a pretty good video on you tube about terra forming Mars. Didn't seem overly outrageous to me. Maybe someone like Elon Musk might give it a try.

    SpaceX has payloads to near earth orbit down to $2,500/pound.

    For 200 pounds of person plus luggage that would be $250K + your share of the weight of the spaceship being launched (which is probably more than the $250K).

    From there, one would need a transfer ticket to the space station orbiting Mars and a transfer ticket to the Mars surface from there.

    Then, one would need the various tickets to get back home.


    And, there will be people who will want to be paid along the way - supply you with fashionable outerspace wear, help you crap and barf in a weightless environment, etc., etc.

    Humans have already colonized Mars.
    "Mars is located in southern Butler County at 40°41′48″N 80°0′44″W (40.696594, -80.012205),[4] about halfway between the cities of Pittsburgh and Butler. The small community is nestled in a small valley along Breakneck Creek. Pennsylvania Route 228 bypasses the borough to the south, leading east 4 miles (6 km) to Pennsylvania Route 8 and west 5 miles (8.0 km) to Interstates 79 and 76 in Cranberry Township. The Mars-Evans City Road leads out of town to the north."

    Thanks for this vid. The thought of an asteroid having a 2.7% chance of impact (with an increasing probability on successive orbits) is a scary thing.

    So far, most objects like this are first discovered by individual citiznens, amazingly enough. The recent object entering the solar system was discovered by some guy in Russia.

    I've heard we could do FAR better if we had a satellite flying on the sun side of earth and looking back toward the sky, thus being able to detect these objects due to the difference between solar heat and the cold background of space.
