The basics of Artificial Gravity – Space Pod 05/11/16


TMRO Correspondent Lisa Stojanovski spins a tale on the potential problems of artificial gravity, and why we don’t have a centrifuge module on the International Space Station.

    Excellent ‘pod, ministoj!

    The topic of artificial gravity is one I have been passionate about for some time. Thank you for breaching the subject.

    The most crucial part of the simulated gravity concept is indeed the “r” – the radius. In order for the person to have very little difference in gravity from head to toe, as you demonstrated in your ‘pod, is to have the radius as large as possible, so that the “delta-r” (difference in the value of r) is tiny compared to the overall radius. This means that a functional facility with centrifugally simulated gravity would be somewhere in the neighborhood of a couple thousand feet. This, in turn, means the facility itself will have a diameter of about 3/4 of a mile or more, for best results. Obviously, we are not building that facility on the surface and lifting it into orbit. It will be manufactured in space, and probably from resources mined in space.

    Can this be done? Yes, but not right now. Very soon, I hope. There are some technologies that need to be developed first. Asteroid mining, smelting in orbit, orbital manufacturing, etc…
