Rehabilitating Mars

melt the icecaps

there is a potential showstopper: Martian life

What evidence is there of Martian life?

You do know the meaning of "potential", don't you?

Mars doesn't have oceans. Where shall the Martian O2 come from?

The O2 shall come from the photosynthesis of CO2.

Photosynthesis requires equal quantities of water and CO₂. Mars doesn't have oceans, and it doesn't have much CO₂ either.

Suppose we could take all the carbon out of its atmosphere, leaving just the O2. You would still die.

From what?

You would die from oxygen starvation, of course. The highest atmospheric pressure on Mars is about 1% of sea level pressure. Even at 100% O₂, that low a pressure is far too low to sustain life. Only a handful of people are able to climb Mt. Everest without supplemental oxygen. The pressure at the top of Mt. Everest is 30 times that the pressure at the bottom of Mars' Hellas Planitia.

Mars would hang on to an Earth-like atmosphere for several million years,actually, according to Martyn Fogg; back in the Noachian period, Mars probably had a respectable atmosphere for quite a long time.

But on the timescale of the age of the solar system, that counts as a rapid loss. We could terraform Mars temporarily, but not permanently.

yea well terraforming would take couple thousand years...not more..so its worth it. It will be done on a side while we living in our own capsule homes and domes.

[Enmos]

What the hell are you? Australopithecus afarensis?

No, I'm Homo sapiens sapiens.. and ashamed of it at times.

You will not live two thousand years. If history is any guide, our civilization will not live two thousand years. So I ask again, why?

How can anyone tell that without actual geological studies done? It would seem to me that this is only conjecture on anyones part without all of the facts known.

Mars doesn't have much CO2? Are you joking? 95% of the Martian atmosphere is CO2.

[draqon]

D H... Mars has 95% carbon dioxide gas, 1% nitrogen, 1% argon, 1% oxygen...and other trace gases...

Mars caps are made of lots of frozen ice water and frozen dry ice (CO2)...the South pole of Mars is mostly frozen dry ice but North Pole is made mostly of water ice.

Mars has seasons were water ice and dry ice travels by sublimation from one pole to the other through seasons...making poles rise and lower.

Mars surface is rich with oxides of metals like magnesium, aluminum, and silicon....


Mars is ready for full scale civilization and we need to rehabilitate it, well at least those who are interested in it. Now D H...you are not an advocate of Mars colonization I see...well than so be it...I am trying to see followers who would want Mars terraformed just as I would want it.

Tell us hop you are going to prevent all of the RADIATION from hitting everything that is there?

[draqon]

Tell us how you are going to prevent all of the RADIATION from hitting everything that is there?

there are many ways

1) by terraforming mars atmosphere...to make it have more clouds and less radiation through

2) by have everything by shielding it with metal or with plastic (plastic has very good ability to repel radiation)

3) By utilizing black fungus in layers of houses to absorb radiation

4) By living underneath ground or in ice...

5) By utilizing new technologies to have combat radiation effect on health...such as nanomachines within the body that every astronaut will have that will constantly repair any damaged cells.

[cosmictraveler]

But the things that you'd need to tereform Mars like trees and green vegitation would die froim all of the RADIATION that is hitting Mars now. So planting anything on the surface will only mean that it will die very quickly.

no cosmic...noone is planning to do it right from the start...the plan is this:

1) astronaut arrive on Mars
2) They build and assemble domes
3) domes are were plants are grown with good temp and pressure...
4) factory for dome production and necessary astronaut equipment is assembled...uses resources of Mars like silicon and aluminum and magnesium to produce electronics and metal parts and make glass (from silicon)...for domes
5) energy cells are utilized by gathering either solar power or using nuclear reactor (I am more for a nuclear reactor)
6) while all this expansion is going on...the ice-caps are melted...some water escapes and adds on to atmosphere of Mars...first slowly...but than surely more and more...


7) the radiation on Mars greately varies by altitude above Martian sea level...so building bases in asteroid impact sites and canyons is a MUST or building it in ice or underground is also a choice.

8) all this activity on Mars would mean humans and their machines will release waste gases to martian atmosphere...which would create some greenhouse effect...at some point the dry ice within ice-caps will melt and become all gas...(since dry ice melts at very low temperatures) thus increasing atmosphere greenhouse effect.

9) At this stage is were the terraforming will start by converting that carbon dioxide to oxygen by photosynthesis using plants or new technology...

Robert Zubrin has outlined many aspect of Martian colonization and terraforming

[cosmictraveler]

They already tried the domes and they don't work.

Biosphere 2 is a 3.14-acre (1.27 ha)[1] structure originally built to be an artificial closed ecological system in Oracle, Arizona (USA) by Space Biosphere Ventures, a company whose principal officers were John Polk Allen and Margret Augustine. Constructed between 1987 and 1991, it was used to explore the complex web of interactions within life systems. It also explored the possible use of closed biospheres in space colonization, and allowed the study and manipulation of a biosphere without harming Earth's. The name comes from the idea that it is modeled on the first biosphere, which is the life system on Earth. The funding for the project came primarily from Edward Bass's company, Decisions Investment, and cost $200 million from 1985 to 2007.

Bioshphere 1 and 2 were immaturely done projects that lack the scientific knowledge of NASA and Roskosmos...say. That said, I believe Biosphere 2 project was partly a success...just because gas escaped does not mean it is not possible to always keep it inside. Their issue was engineering...they should have had compartment within biosphere to isolate leakage of gas to outside.

[draqon]

anyways in addition to that...I really, really, really hate the people involved with Biosphere project, they are brutes because of their lack of scientific knowledge and engineering thinking...the whole Martian colonization just got a setback. I really hate them.

[cosmictraveler]

So if it is that difficult to engineer here on Earth, think about how many more complex problems there are going to be on Mars!

yea well...Mars is my goal...and problems as complex as they are can be solved.

ISS is a success...its floating well...so was MIR a success.

D H... Mars has 95% carbon dioxide gas, 1% nitrogen, 1% argon, 1% oxygen...and other trace gases...

95% of "not very much" is not very much. The average surface pressure on Mars is less than 1% of sea level pressure on Earth. If you want a breathable atmosphere on Mars, you will not get it by photosynthesis. Mars does not have enough CO₂ or enough H₂O.

dont worry about money...monarchy can be set up to accomplish a goal.

Draqon, you are verging on venturing into woo-woo land here. You might want to rethink what you have said, and in the process, rethink this entire silliness of terraforming Mars now.
