    Cool!

    5.57? Did you drop some zeros? If it was 5.57 you'd be inside the supernova.

    If you want to do some complex radiation sims, go to NASA's OLTARIS. https://oltaris.larc.nasa.gov/

    Two contra rotating cylinders.

    I know. This is supposed to be the ultimate ultimate challenge, because it has never been done. You can use command seats and use a second vessel to transfer a kerbal. Or take command.

    The image didn't imbed. I put the link into a spoiler to prevent page loading issues.

    Read some of the answers from the actual what if website... https://what-if.xkcd.com/4/ If space was full of air, how far away could you hear a supernova?

    Bye the way, the original FH wasn't going to be reusable. The 4 year delay made sense because they had to develop reusability for the F9 first.

    You can send drones ahead of time to scout the area, plus orbital mapping. Mars's surface area is the same as Earth(no oceans), so there is probably somewhere suitable. I agree. Yes.

    That's a good idea. Spacecraft with large populations and the need for gravity should have 2 contra rotating tori, otherwise it gets even harder to turn. You could use vertical farms and hydroponics. Here again another hand waving argument. Why? There actually is water in the soil.
  11. DAL59
    That could be solved with reaction wheels, or a rotating drum within a stationary cylinder(which would probably happen anyway.)

    There is plenty of ice and soil moisture and underground glaciers other than at the ice caps.

    @ShadowGoatOkay, i've signed you up.
  14. DAL59
    No! It is a perfectly legitimate design and is structurally possible as long as it is less than a dozen kilometers in radius. Also, nothing would vibrate if they inside a cylinder rotating at a constant speed. Inertia.

    Okay, you got it, but you are no longer booked for mission 7. Also, welcome to the forums!

    The regolith can be piled on the habitats to block radiation. There's still ice in craters.

    There is still a lot of water ice in craters and at the poles. And in the soil.
  19. DAL59
    There's still enough to process into water for drinking. In fact, its launching on the 2020 rover. This could be true within the next few decades due to AI. However, for the time being, the teleoperation time delay is a large hindrance.
  20. DAL59
    There is humidity in the air. True, but I meant that it could be used to make the orbital habitats you were talking about. We've sent radiation detectors into interplanetary space for years. The amount of radiation is well known. Why not go to a crater where there is a pool of ice in the middle?

    Which don't establish colonies... Me neither. As Zubrin said, its like "shooting soldiers to study wound pathology"

    "interesting..." was the first comment on youtube

    So.......

    @cratercrackerThat is delphinus.

    1. The radiation is not actually that high, as debunked by Zubrin many times. 2. Suitports 3. There are subsurface glaciers. 4. You do not need closed loop life support. You can extract water and air from the martian environment. http://www.armaghplanet.com/blog/the-amazing-aldebaran-spacecraft.html Also, asteroid mining. What is the difference in medical knowledge gained from a lunar orbital station than from the ISS? The DSG seems to exist solely to give money to boeing and lockeed martin. And many of those problems could have been fixed by humans...
