MARS one on 2025

[operrajunk74]

I thinks it will be a one way trip for all the participants.  They don't possess the necessities to accomplish keeping those people alive.
They will really be sorry they did that.. in the end and we will still be warring our selves to death here on Earth and waiting for Russia or China to sell us rides up and down to a new SSI station.

It seems that some users have exposed MARS one as a scam but it was not needed if the governments of the world cannot do it then, no one can. Besides there is simply not a good reason to go right now to mars, maybe in the future, there’s no rush.

There is a very good reason to go to Mars - all of humanity's eggs are on one basket planet - literally. 

I disagree with this if that is what you want, the moon could be enough. When I made my statement I meant “economic reasons to go to mars”. If an extinction level event that could destroy the earth and the moon was detected then we will have a reason to go to mars, but since this is not the case I think we’re fine on planet earth.

No.

It is actually a bit less costly in propellant to go Earth to Mars as opposed to Earth to Moon.  Also Mars has plenty of the elements needed for life, such as N, H, and C.  These basically do not exist on the Moon, with the possible exception of the ice deposits currently being studied at the poles.

Because of the lack of basic elements on the Moon, it is not possible to build self sustaining colonies there.  For example, you could not make plastics.  Iron could not be turned into steel because of the scarcity of Carbon.  Many such issues.  The Moon is good for many things, but human settlements, no.

Mars is better suited, but we are a long way from ready to do it.

Until such a time that we find that Mars has humic microbes, we would need to take some along if we ever wanted grow any plants in Mars soil.

There is no soil as you know it on Mars.  Soil here is over 40% long decomposed insects and fauna.  Think of Martian soil as simple powdered rock.

Powdered rock along with water, nitrogen, oxygen and carbon are exactly the things that humic microbes need to make soil. Of course, the process is enhanced by other things, including certain fungi that can live on rock. Extra protection for humic microbes from radiation may be necessary, since the atmosphere of Mars is so thin.

Wikipedia tells us that the process isn't fully understood. Possibly we would have great difficulty creating soil out of Martian rock on Mars, and it might even be impossible to do and maintain outside of laboratory conditions.

Any "gardening" that was done on Mars would have to be done inside a pressure vessel with artificial lighting and as you mention, "manufactured soil."

There is no known way to make such vessels on Mar out of native materials, and certainly no known way to make the parts for artificial lighting or collection of solar power, and creation of electricial to run artificial lights.  These areas would have to be temperature controlled.

All together this makes it very difficult to think in terms of acres of farmland.

Now how much land does it take to support one human?

A company called Bigelow Aerospace may have the answer. They have built blimp-like space stations - http://www.nbcnews.com/science/space/bigelow-aerospace-shows-its-expandable-space-station-future-n322521. NASA is looking into this, and the thing might actually be way more practical than a first glance would suggest.

Float a blimp to Mars, or fly it there on a spacecraft, and set it up on the surface of Mars as a habitat. Actually, many such blimps could be shipped to Mars, un-inflated, in one flight. All materials for living conditions could be onboard.

Google "blimp space station" for more info.

One acre of potatoes will feed a man for one year.

Now figure the WEIGHT of "habitats for plants" that would need to be sent to mars to support that one person.  Multiply that weight by the number of people you want in the "colony."  Then figure the useful lifetime of the equipment, and figure the WEIGHT of the resupply missions.

[Vod]

Before people say potatoes don't weight much - it's not the weight of the potatoes but the half meter of soil you'll need to carry, not to mention fertilizer and water.  Soil that will need to be re-energized each year by the death of billions of insects, which of course won't exist there.

We won't make it to Mars until we have colonized the moon and are creating what we need there.  It takes 1/6 the energy to lift off than from Earth.

This issue of "growing plants on Mars to survive" is exactly the plot of the upcoming movie, "The Martian."

[Violincoin]

First we have to go on the moon again.
Mission is planned on 2020 if i'm not wrong.

[pilscoop]

This is a really romantic idea. I don't see it as a serious project. It would be really nice if NASA got a serious budget to plan a real mission like this.

[BADecker]

The problem with NASA programs is, it works off grants off taxes. What this means is, if there is anyone who happens to be dead set against NASA, he is forced to help pay through taxes.

In other words, any moon or Martian plan is a slavery plan for many if not most of the people.

[Spendulus]

Wrongness bolded.

Try "we need to learn more about" instead.

Exactly.

In addition, we don't need taxes to go for doing any of it. Somebody want to volunteer their funds and life? Have at it. Just don't force the rest of us to finance something that we don't want.

Not really.  It's CAST as a really romantic idea, a great adventure.

Reality is it's people living in a can or more likely, in a can buried in a cave, and having to put a complicated suit on anytime they go outside.

You beat me to it. I was going to say that. Anyway its a very clever movie, it gives people idea of how they are going to Grow plant on mars, if there is another mars mission then people will have the general idea of how to grow plant on mars.

I read the novel and was impressed.  At that time I did think it would make a good movie plot, a la "Castaways."  Very curious as to how it presents on screen.

We're Going to Mars... FINALLY!

... and the rest of the Solar System - Elon Musk Explains - VIDEOs

...

SpaceX Founder, CEO, and Lead Designer Elon Musk will discuss the long-term technical challenges that need to be solved to support the creation of a permanent, self-sustaining human presence on Mars. The technical presentation will focus on potential architectures for sustaining humans on the Red Planet that industry, government and the scientific community can collaborate on in the years ahead.

Jeff Bezos's New Rocket Will Be Bigger Than Elon Musk's

Blue Origin was the first private spaceflight company to launch a rocket into space and then bring it back down for a vertical landing. "Into space" has a bit of a caveat attached, though; the New Shepard rocket crossed the Karman line, 100 kilometers above ground, which arbitrarily divides earth from space. The rocket can't make it high enough to deliver a payload into orbit the way SpaceX's Falcon 9 can.

But those caveats could go away in a few years. In an email today, Blue Origin (and Amazon.com) founder Jeff Bezos revealed plans for a new rocket series named New Glenn. Named after the first American to orbit Earth, New Glenn is also destined for orbital space, and Blue Origin wants to launch it before the end of the decade.

This Mars mission is a suicide mission. The safety of the crew to be sent there is not guaranteed and there is no going back. To those who enlist themselves if they survive they will become heroes of the future colony to be established on that planet but its such a pity for them to be distant to their families. Some conspiracy theories tells that this mars mission is one step done by mankind for an interplanetary habitation, since earth will soon be inhabitable. We dont know the truth but its also good that man has thought of transferring the population of the earth to another planet and it is good for the future populace of humans.

Actually it's possible to create a sustainable habitat for humans on Mars, but no body has done this.  It's not a matter of just sending one or two supply ships before the manned expedition goes.  Think in terms of a hundred ships before the people go there.

You'd need to prospect, and find sources of many elements and materials.  For example, you would need to find a local source of copper, then mine it. 

Think in terms of large numbers of robots, industrial processes, fabrication in operation before people. 

Realistically this is a fifty to hundred year project, but it definitely should be done.

I agree with regard to the sustainability. Here on earth, the few sealed habitats that we have built, have not lasted long enough, sealed, to see if they would work as long as they would have to on Mars. I don't think we are or will be prepared enough by 2025 to attempt a Mars mission safely.
