How many years will it take for humanity to be able to live in Mars????

Manning Mars is not due to any political reasons like the same for moon during cold war.\nEstablishing human civilization in Mars is very necessary for saving homo sapiens, given earth can face disaster at any time.\nSo not only rich, scientists, people from all spheres of life will be required to go to Mars for humanity to prosper there.\nIt seems another 20-25 years will be taken (based on various articles I have read).

Very good question.  I went searching and came up with this:\n\nBTW, the person that answered 687 is correct for EARTH days, not MARS days.  It appears to be closer to 668.6 Martian days.

i say we will walk on mars in the next 50 years, as far as living there, maybe in the next 100-150

Yes, You might have heard about terraforming. Recently i gave a seminar on it. It is the method to transform the mars so that its environment can support life as earth do.  But the only thing required is you and we to get together and work hard with unity for this project. This project is neither going to be of one country or one group but the entire man kind has to work together for it

Still no life is mars,\nLet mars be the beautiful. if life comes there also then it will be earth.

are you living in Mars??

The Earth is a finite resource and will become uninhabitable one day.   Global warming, nuclear accident, hit from a big rock from space - there are plenty of disaster scenarios.\n\nWe need to be prepared.  To that end NASA needs to do so much more research, travel to other planets, set up a base on the moon and mars and, above all work towards spaceflight being like flying today.   Sound far fetched?   When my dad was a boy man couldn't fly and before he died men were standing on the moon.\n\nProfessor Stephen Hawking, he who wrote 'A brief History of Time', recently stated that if mankind did not seek out planetary travel pretty quickly there was a good chance a natural disaster would wipe out all human life!

I'd like to a base on the moon, where we can launch our craft to explore Mars.\n\nBut I do not think it will happen in my lifetime.

20 years? hmmm... by that time we will probably be so overpopulated that scientists will have to think of building communities on other planets to accommodate the ever growing population of earth...

I'm surprised nobody has mentioned this, but it takes a *lot* longer than a few hundred years (a few generations) to result in a new species.\n\nOn top of this, the environment for colonists on Mars would not be that radically different from the earth's environment.  Life support would have to maintain the same atmosphere, temperature, radiation, environments, the same food and water requirements etc.  Probably the main difference would be the much smaller gravity on Mars, which would badly deteriorate human muscles and skeletons unless some other measures were put into place.

read this.  http://news.yahoo.com/s/space/20060522/sc_space/towardimmortalitythesocialburdenoflongerlives  i think it WILL happen. and for me i WANT to live longer. I want to see our species travel beyond our solar system and find new life. Then i will be happier.

If you are referring to the Mars rover mission (Spirit and Opportunity) it started in 2003. It was scheduled to last about 90 days, but after a full Martian year (more than two Earth years) the rovers are still going strong.

No other planets are habitable for humans.\n\nMercury and Venus being far too hot.\n\nJupiter, Saturn and Neptune for being gas giants and so has no solid surface. The gravitational pull of these planets would crush our bodies. Juipters gravititational pull is over 300 times the earth.\n\nPluto is too far away thus seeing temperatures of over -200 degrees C.\n\nMars would have been a perfect candidate, as the temperature is quite similar to earth's at occasion. But our lifes need plenty of water and the abundance of water on Mars is basically zero.\n\nFor other life than humans, a moon called Europa, which orbits Saturn, contains frozen methane and water, which could harbour life. The only problem is its a moon and not a planet.\n\nThere are all the other planets (approximately 250 so far discovered) in the Keiper Belt which need to be examined

There is a very specific answer to this question at the link below.  Just so you know, it will take about 5-7 years.

It should be habitable for another billion years unless we do something to deal with the increase in energy the sun is giving out.\n\nThe Earth should be destroyed after about 5 billion when the sun becomes a red giant (unless of course we remove some mass from the sun to make it last longer).  If it isn't destroyed by that then it'll last a very long time (not sure how long, could be until end of the universe however that happens) but it won't be very useful (except for materials).

The sun will blast in 4.9 billion years.  It will began to expand and then it will just explode.  Most life on Earth will end well before that though.  Some bacteria may still thrive, such as archaebacteria.  \n\nAlthough, humans will evolve to become much more complex organisms, that we may even be able to withstand the heat.  It took about 1 million years for humans to appear and evolve to what we are today, so just think about 4.9 billion years!   \n\nWhen the sun explodes though, I believe that humans will move on to an Earth-like planet, such as the ones scientists are trying to find right now.
