Anyone else hear about this idea, I think its pretty clever. Building non-atmospheric water ice/liquid inflatable craft and using the water as a low thrust high impulse engine fuel. This design also, potentially, solves other issues like hull integrity, radiation shielding, self-sustainable life support and maybe even supplying oxygen and hydrogen gases.

Why aren't we building a moon base yet?

So hear me out guys, getting on the moon is seriously important.

Why is it so expensive and difficult for us to send things to space? It's because of 2 things, breaking free from the Earth's gravity and surviving re-entry into the atmosphere. All of our rockets, satellites, space probes, etc. have to have a massive amount of fuel and ablative armor.
The moon is located in a strategically beneficial spot, right at the top of Earth's gravity well. Once we spend the initial capital to establish a permanent or semi permanent settlement on the moon, the door to space really opens.
We can then design our spacecraft without the need for massive thrust and armor, and wont need to spend nearly as much fuel to get around out there. It doesnt take much to move an object through space, and breaking free of the moon's gravity is exponentially easier than breaking free from Terra. And moving resources from the moon to earth is even easier, just a little push and they fall back to earth on their own. With even a tiny colony on the moon to act as a port of sorts, the trouble of monetizing space mining is essentially solved. Not to mention the insane amount of solar power that can be gotten from the raw, unfiltered power of the Sun.

We need to do this guys, we're quickly running out of several natural resources, rare earth metals in particular, which we're only just beginning to rely heavily on (theyre used in just about any battery, especially phone batteries and electric cars) and they can all be found in the asteroid belt. The Moon is the answer, and it's right at our doorstep. If we could get there in the 60's with the computing equivalent of a dollar store calculator, then we have no excuses to not go with today's technology.

>TL;DR- fuck solving world hunger or social issues, lets just go to the moon.

Do you think the "Earth will not be habitable forever, we need to move on" message will get through to the politicians and other idiots? Nevermind the religious nuts who want the apocalypse to happen.

You still have to get all the fuel and stuff to the moon, and assemble it there. May as well just do the same thing with LEO if you're going to space anyway.

But that's wrong Walter, it's already there. There's an initial investment of resources sure, but that's true of anything.

Consider what a sonic boom actually is: a pressure wave.
Matter waves pass through one another unaffected.

a sonic boom colliding is redundant because a sonic boom is all ready the over stacking of sonic waves, isn't it?

But what if two jet planes traveling mach 1+ pass by each other, would the two groups of stacking sonic waves even interact with each other? or like the other guy said and pass through each other.

I for one, hope that they would create a MEGA boom.

the flow chart would be as such
super->mega->ultra->SHIT NIGGA YOU CRAZY

What are some curious theories on what this all is? Existence in the universe is mind blowing when I sit down and think of what we are really a part of. What are your own theories about what we call 'space' is? Like, what's going on from a bigger perspective? Or smaller?

I made up a story for school. Where the universe is a gaint being thats further then the 4th dimension and we live like microbes inside of it and only scens this being in a 3th dimensional way . But its on a scale so big we cant understand further than intended,just like microbes we just live our purpose but cant visualise the being where in. And black holes are like a chemo killing microbes or problems that harm the universe.

Don't believe the hype.

Thanks for the heads up but I gotta say the ISS is lame as shit, we can do better than that.

How about a spinning ring station tidally locked between our moon and the earth?

No, ISS is fine.

There was however an ISS-bound Progress cargo ship that got damaged on the way up somehow and is tumbling uncontrollably. That may be what they're thinking of.

yeah, that would be way better.

I think ISS is situated so that they can ditch it if they want to stop paying for it though.
the ring station would probably stay up a lot longer.

but to be fair it is the most expensive object ever created by mankind and arguably one of our greatest acheivements.

Kind of a dumb question.

To live on another planet would the sun and the atmosphere be exactly like earth's? Or could we survive near a red dwarf if the planet was just at the right distance to maintain earthlike temperatures?

I guess personally I do actually believe there is a formal point of life in the grand scheme, but that's sci fi stuff. I didn't realize it came out so much, but I still stand by it.
There must be natural rules to alien life, universal forms, just like the formation of mountains. If evolution is dictated by the environment, similar environments should create similar life. We are more related to horses than we are to deer, but similar habitats, similar place in the food chain, and similar food sources created similar animals, at least morphologically.

We won't be having hamburgers in space.

Or milk or eggs, for that matter. For every cow slaughtered for food there must be an incredible amount of food grown to sustain the cow. In space stations this may not be feasible due to limited space and resources. We'd be better off focusing energy on hydroponics and a vegan diet would probably be necessary in a long term colony or space station.
