how much oxygen is on mars?

Question

If we were able to make a ship to mars and I'm acting like i'm a biomedical engineer and we need to build the ship ,the fuel, and the place on mars.

Answer 1

First of all, what water is on Mars?? The ice caps are actually what we here on earth call "Dry Ice"... otherwise known as frozen carbon dioxide.

The first two were right. There is hardly any Oxygen in Mars' atmosphere. There may have been millions of years ago, but we can't tell that yet.

To answer your question, we have the technology to make it to Mars (it is under development at least), however we are starting with the Moon as a "testing ground" of sorts to develop the habitat technologies for long-duration stays in low-gravity, minimal atmosphere environments.

A great site to check out would either be nasa.gov of course where there is a ton of info on the subject. Or you can see a senior design project on this very subject done by my Alma Mater at Purdue University. Just browse the page, and check out the presentation (downloadable from the main page). There are some great ideas pertaining to what would be necessary to live and work on Mars.

Hope this helps.

Answer 2

There is not enough oxygen in the atmosphere to support any macroscopic terran (earthly) life. A convenient way to generate that oxygen would be to pass an electrical current through the water that can be found there, this would produce not only oxygen but also hydrogen, which can be used as fuel when solar power isn't available.

Answer 3

actually there is no oxygen on mars. i mean like non in the atmosphere. but the redish glow if the planet is caused by rust. rust can only be created my mixing oxygen and iron. so in the crust of mars there is probabily about 10 times the amount of oxygen as in our atmosphere. after all in the rocks on our planet there is about another 20 times the oxygen than in our atmoshpere. the only problem is that it is very dificult to remove the oxygen from the planets crust. so the planet simply could not sustain any life that we can comprehend. but i hope that answers your question adequately.

Answer 4

Actually there is probably a lot of oxygen in the Martian atmosphere. It is not free oxygen as on Earth, but is chemically bonded to Carbon in the form of carbon dioxide (CO2). However, it still isn't a lot as the Martian atmosphere is very low pressure.

Answer 5

Earth Venus Mars
N2 0.79 2 3 x 10-4
O2 0.20 < 0.001 10-7
Ar 0.01 0.005 2 x 10-4
CO2 0.0003 64 0.009
H2O ~ 0.02 ~ 0.01 ~10-6

Total 1.00 90 0.01

Not a whole big bunch, in other words.

Answer 6

none i think
cuz i dont think their are trees and
plants their so i hope you have fun
finding out about mars lol
