I am doing a science project and I just want to know how expensive the compression and transportation of oxygen to mars would be for a bout 1,000,000 people.
Well, that is silly! You don't send a million people someplace and ship oxygen to them in bottles. You send them someplace where they can produce oxygen locally. Same for water, and food, and anything else a civilization needs. Even oxygen for one person costs too much; that is why they send robots, and the robots run on solar cells.
Mars has no lack of oxygen. It would be far cheaper to crack the local minerals for the oxygen locked up in them.
Figuring the cost of a rocket-ship. Then a nice high end little robot, we'll name him Hirm, to do work on mars (Human Intelligent robot mode) The cost of smart people to work hours at computer in a rented warehouse looking place. Cost of rock fuel.Toss in the cost of ship to deliver Hirm, and the cost of all his supplies. Luckily we got a deal on air, that's free! and we come around....*calculating*
Well if we raise taxes I am sure we can come up with enough to do deliver air to mars!
Why would you want to do that? There's tons of oxygen on Mars in the form of water (H2O) and carbon dioxide (CO2) from which you can easily extract the oxygen.
The major elemental constituent of the crust of terrestrial planets like the Earth and Mars is, guess what oxygen! (what are rocks made of?) So, there is no need to bring it from anywhere else.
