    There is a Nobel price to a person who explains gravity. The one who then invents artificial gravity plates becomes billionaire. Both are needed for long stay in space.

    Interim solution is to build rotating ring. Current space stations are way too small for this solution.

    Humans are not built for micro gravity.

    Not quite sitting for 19 hours, there is some room to move around, get dressed and undressed, go to the toilet etc. At some point someone even showed that there's enough space to do a back flip.
    The next mission planned for end of September will be a lot tighter though since it will be 4 people in there.
    It's in pubs where the world's greatest ideas begin.

    Seeing as we don't really understand how gravity works artificial gravity is probably centuries away if at all. Problem with rotating rings is the angular momentum, walking with the ring rotating and then turning sideways will be a very strange experience. Amore realistic solution would to sustain acceleration during the first half of the flight and then deceleration during the second half of the flight - this will deliver a gravity effect indistinguishable from normal gravity.

    Humans have lived in the space station longer than the 7 month transit time to Mars so think we will cope with the lack of gravity.

    A bigger issue will be the exposure to radiation during the trip, even in the space station astronauts still receive some protection from the earth's magnetic field.

    -not quite as sleek and elegant as the other rockets by SpaceX -but an incredible achievement!

    -a wobbly flying beerkeg dances on a gimballed single engine ( the final spaceworthy model is to have 31 of these engines) to hop 150 m and lands nimbly on it's tiny feet

    Amazing!
