A manned mission to mars. Reality or fantasy?
Forums › General Discussion › A manned mission to mars. Reality or fantasy?-
Just wondering what you guys thought about a manned mission mars. I recently read the book "Case for Mars" by Robert Zubrin and agree with the idea... Thoughts?
-
Sure if NASA wasn't scrapping space programs. I always thought we'd make a try for Mars. Now, I dunno. NASA doesn't have the funding they used to.
-
I think we should. I really like the idea of space exploration in general.
-
I've been doing a little bit of research, and the terraformation is a realistic possibility. It amazes me that we have the technology and the resources to fund a mission but that it hasn't been done. A series of manned 900 day missions to mars will cost anywhere between 30 and 50 billion dollars. Hell, Bill Gates could fund it.

Apollo astronauts were not exposed to three years worth of radiation.

I've done my research on this one. As long as they have protection on the shuttle and radiation resistant suits on the planet, they will come out with an under ten percent chance added to the original chance of acquiring ancerTheNewfieBullet wrote:

We don't have light weight protection for the vehicle at this time. I'm sure that problem is being worked on but will require a big advancement. And suits do not have anywhere near the protection required. Any activity involving suits would need to be severly limited.

It would have been a reality.

It's very possible. It would just take mass amounts of funding. They have already come up with several ways to "terraform" it to make it more hospitable to people

I know that they are composed of CO2 but there are large pockets of hydrogen sealed inside the ice caps. I forget what else there was, but I am fairly certain tht enevtually the air will become breathable. Forget how. damn. I'll get back to you.TheNewfieBullet wrote:

perhaps releasing that CO2 would create enough of an atmosphere to warm the surface above freezing. that would release lots of gases. but oxygen comes from photosynthesis, it would require extremophile algae to begin turning that CO2 into oxygen.
If we had the means to do that why would we? It would be easier and cheaper to just live in space. Harvest asteroids and comets for raw materials, go wherever we wanted. Free solar energy. Ion propulsion. Don't need Mars' gravity well.

Yes that's it! The reason it would take so long would be the need to create oxygen through vegetarian growth. True, living in space would have its advantages, however, we must also consider the fat that there may be miniature life somewhere else. IMO mars is as good a place as any to begin the search.perhaps releasing that CO2 would create enough of an atmosphere to warm the surface above freezing. that would release lots of gases. but oxygen comes from photosynthesis, it would require extremophile algae to begin turning that CO2 into oxygen.

Check out "Rare Earth" by Ward and Brownlee. It makes a good primer on what you'd need to build a sustainable and livable planet.
