Of course not. It's made from unobtainium. Literally tells you right there it is unobtainable.

Fun fact, you can see Alpha Centauri B in the night sky of Pandora in the first film. It's an unusually bright star.

Yes, and there's a scantily clad Na'Vi girl waiting for you there.

Reply to What is our current "best guess" about how to observers that entered a black hole on opposite sides would look to each other once they crossed the event horizon? by WittyUnwittingly
The amount of speculative mumbo-jumbo here is amusing.
The short answer, of course, is that they would both be dead from spaghetti if Acacian. The title forces of the insane amount of gravity would tear them to shreds.
The amount of gravity around a black hole is staggeringly humongous. Just imagine how strong gravity would have to be to bend light.
Everything inside the event horizon is presumably moving straight inward at nearly the speed of light.

It’s about as realistic as a human from another galaxy far far away named Han Solo who looks, acts and dresses like a white 70s American human and uses all the same slang. Oh and speaks English.

In the avatar universe, the interstellar starships can reach 0.7 C / speed of light using Antimatter - Matter engines. We currently understand enough about Antimatter physics to know such engines and speeds are theoretically possible.
Therefore, the time of flight to Prox A, ~4 light years away, should roughly take ~6 years.

There's lots of hydrogen in space but it's spread so thin it's basically non-existent. On the other hand, every year we collectively emit 41 billion tonnes of water made from hydrogen that has been locked away in hydrocarbons. Also CO2 which is the part we're usually concerned about.

Define "Pandora-like." Do you mean one that has a lot of bioluminescent flora and fauna with large blue humanoids? I seriously doubt we can imagine what habitable planets actually look like, but I doubt they will bear much resemblance to the vision of a Hollywood film producer.

We can just dehydrate it, then it will be lighter and not cost as much to move😜

A watery planet? Yes. A planet with near-human looking aliens with hair on top of their head? Almost 0. The upright posture with opposable thumb design is clearly not very common, as evidenced by the fact that the hominid species came into existence for only about a million years in a timeline that spans 530 million years for vertebrates to come into existence. (or 1 million since the 100+ million years that mammals existed) Seems a huge fluke that a primate-like species with 3 cones for finding fruit that eventually becomes upright on the plains will ever popup in the universe.

For what it is worth, water is a byproduct of burning hydrogen. Water reclamation is already a thing and by the time we are in space we will have water reclamation in-built. Capture of ice rich objects will certainly be normal in a space faring culture.

I may be making this all up but I think it was published for PBS, which is like the freeware of television.
If anyone owns the rights to it, I would like to think it would be his wife or foundation.

Reply to Documentaries on Columbia shuttle? by Worthy_Planet375
There’s a government report on the Columbia shuttle. In the last part of it is a rather lengthy ‘well, here’s what we could have done’ type plan and it’s really cool. It talks about how fast they could have ramped up a rescue mission and what it would have looked like.

I will never understand why people think we're ever going to run out of water on this planet. Over 70% of the surface is covered in it, and basic chemistry will tell you that when O2 and 4H are present, they will combine into water. So unless we're somehow consistently splitting hydrogen and oxygen atoms for several billion years, or are otherwise removing water, oxygen, and hydrogen from the planet, we will never run out of water.
Clean, drinkable water, on the other hand, is harder to come by, and for some reason, companies have decided desalination plants and other purification systems are just not worth investing in to provide clean drinking water for millions of people around the globe. Something about "what's in it for me," I think they said.
