That's why they made Earth Mk II.

I can drink them, but drinking them means nothing extra to me.

Plus a ram air turbine. Passengers want windows, though. Plus, large wingspans are not very good. There's a reason they have to fold the 777X wing. Also, so far airplanes put their fuel tanks on the wing and their load on the fuselage - putting the passenger cabin on the wing means now they share the exact same structural part.

Looking really bad now...

Best uncontrollable laughter extra ever.

5 ls : ~1,500,000 km, we'll settle that with 2 solar radii. 15 ls would be 6 solar radii. 30 ls would be 12 solar radii. Parker Solar Probe will approach down to 9 solar radii. See also : tungsten countertop.

If someone still needs to see how reaction wheels really work like (in that you can see reaction wheels init) :

Be careful for everyone in the path.

There are other reasons - a single engine would have to be placed on the fuselage, and as such wouldn't be well-suited for passenger planes which needs lots of space. Works very well for fighter jets though. There's also a reason why engines on passenger planes tend to be placed beneath the wing, and the wing beneath the cabin - it means a quieter cabin. An engine on the tail means noisy rear cabin - fine if it's only cargoes there. Takeoff noise can be reduced by simply expediting ascent. New, higher-bypass-ratio engines also help. Landing is much more difficult, however.

Mostly man vs. self. After all, the world is a much larger place than the humans inside it.

Complex biological life seems to not last very well in microgravity, however. True that from logistics they make sense, it's just that the payload is quite needy here.

The water cares about gravitation, however. You don't want the water the fish lives in suddenly separates off the fish. Or make sure you're "indulged" enough...

You don't want to have protein poisoning though. One of the problem with fishes is just the amount of water that they need. Plus we don't know whether they still work on reduced gravity or not. Although it's possible to create a fish-hydro/aeroponic closed loop - there are installations on Earth that works this way already. If ISS foods are any indication, the solution is to simply make everything more intense than usual. Seasoning helps to that. They're mostly chemicals as well, so you can produce them through other means.

Warning points should worth more than likes. They're much harder to get.

I don't think this one would ever stuck (since it's too complicated for that XD) but it's funny.

Hitchhiker's Guide to The Galaxy. Period.

Probably just you. Try to clear all the cache in your browser.

We only need to judge which one is more detrimental - radiation, or lack of gravity... probably find a compromise between that. But yeah. Space travel is hard for us surface-dwellers.

So equivalent to a whole spaceship made from APCP. Sounds brilliant.

Hmm, yeah... Just... make sure it doesn't end up like a 100x worse version of Apollo 13.

Well I still radiate heat from the warm living quarter onto the tanks... that means now the tanks requires more cooling ? more insulation ? idk. Yeah but we'd still have to make linkages. Nothing magically just stays apart without any reaction being transmitted through.

Wouldn't that mean cryogenic living space ? I don't want to live inside a liquid hydrogen.

Not the case in every country, with every nationality - esp. considering astronauts are often also members of the armed forces. They do have their passports with them in space, and I think they do have special provisions in it.

Won't any material do that ?
