Rockets being passé, China is working on using an electromagnetic railgun to launch crewed spacecraft the size of a Boeing 737, weighing 50 tonnes, into orbit. This remarkably ambitious project is even more ambitious than it seems at first glance.

    humans can still function when insane G forces have turned them into jelly right?

      While railguns are known for rapidly accelerating projectiles to hypersonic speeds over the short length of a gun barrel, there’s no limit on how slowly they can accelerate something or how long the “rail” part of the railgun can be. Accelerating “slowly” over a long distance is totally possible!

            That would put the g-forces back in play: the faster you go around the rail the stronger the centripetal force that keeps you going in a circle. If the rail is straight the force only depends on acceleration not speed.

        It just seems like an engineering improbability to me with the tolerances required. 5+ miles, I guess you could bury part of it to reduce things like wind, but still.

    I hereby dub any crew member sent to space in this manner a Cannonaut.

    If you want to reach LEO velocity and stay under 5g, you’d need a 860km long railgun…

    This was posted in the correct community, because it’s about as real as the hyperloop

      Just to save you guys a click, this is a Google translate of, “some of you may die but that is a risk I’m willing to take”
