    Many people would disagree......

    Whether the above proceeds as planned or not, I do wish them all the bloody luck in the world and every success.

    Which cost allot of money. So far the two bio domes didn't work out and can't be considered to support a colony on Mars. So billions will need to be needed to keep on experimenting to be able to have life support for those who start a colony if that ever does happen. We have many problems here on Earth that need to be addressed before trying to put a colony on Mars so let us get moving on fixing what's wrong here rather than worry about Mars right now.

    Biosphere 2 had two closure experiments, Missions 1 and 2, during which the structure was sealed with researchers living inside. The first, with a crew of eight people, ran for two years from 1991 to 1993. Following a six-month transition period during which researchers entered the facility through airlock doors and conducted research and system engineering improvements, a second closure with a crew of seven people was conducted March 1994 – September 1994. In the course of that second mission, a dispute over management of the financial aspects of the project caused the on-site management to be locked out, and the mission itself to be ended prematurely. The sealed nature of the structure allowed scientists to monitor the continually changing chemistry of the air, water and soil contained within. Health of the human crew was monitored by a medical doctor inside and an outside medical team.

    In time, all those problems will be fixed. Perhaps if we, the world cease all militaristic endeavours and put that large amount of money to alleviate hunger, poverty etc.
    Why take it off science and the new frontier.
    We are going to Mars, that is certain.

    With robots for now. The arms dealers are stoking the fires of war in many areas of the world so that countries like America has to ramp up their military abilities. It isn't America that starts wars like the Ukraine or ISIS. Countries must protect themselves but it is a never ending war. The next big step to do is to send a craft to Mars and pick up rocks then return back to Earth.

    None of which supports your earlier erroneous statements.

    And I think it important to take the water issue further. Your definitive, absolute statement was : "Where do you get oxygen and water from since neither exist on Mars."

    It is intellectually dishonest to move the goalposts, as you have done here. You are now insisting the surface is dry and subfreezing. Did I deny this? No, I noted that the poles were covered with ice (there is your subfreezing), while ice could be present in the upper crustal layers (there is the absence of surface water - and freezing again).

    Cosmic Traveller, no sensible person would think any less of you for being ignorant of a couple of points about Mars. So why not simply say, "good points, I see I was mistaken"? Will you now please concede that there is water on Mars? And, as I have implied and now state, that such water would be accessible to colonists.

    Well thank you for pointing out mistakes. The thrust of my statements were that trying to colonize Mars would be almost impossible to achieve with todays technology. I brought up things which supported what my thoughts were about colonizing Mars, lack of atmosphere, no magnetic field, 200F degrees below zero temps cosmic radiation. Lack of atmosphere doesn't mean no atmosphere but as you point out there is a very thin atmosphere which really isn't very helpful for humans.

    Water that is frozen underground would be difficult to extract for as you said it is frozen.

    I'm sure if we put our minds to it right now, it could be achieved within a decade. The biggest problem would be enroute protecting the astronauts from solar radiation etc.
    Water would be well within our capabilities to extract, as would the subsequent production of Oxygen.
    Your biggest mistake is to seemingly want to halt progress because things on earth are not as most of us would desire it to be.
    That didn't stop scientific progress in the past...it didn't stop us from going to the Moon within a decade of putting our minds to it.
    As mentioned earlier, orginizations are making plans to send humans to Mars right at this time, and within a decade. http://www.mars-one.com/
    And although I'm not sure how realistic those dreams and endeavours are, I certainly wish them all the very best, and all the luck in the world to successfully achieve their goal without any mishap.
    I'm sure we all, to a man/woman also wish them the best.

    We are also looking further afield to stellar travel by companies such as the NASA backed and supported http://100yss.org/
    The 100 Year Starship (100YSS) is a joint U.S. Defense Advanced Research Projects Agency (DARPA) and National Aeronautics and Space Administration (NASA) grant project to a private entity. The goal of the study is not to have the government fund the actual building of spacecraft, but rather to create a business plan that can last 100 years in order to help foster the research needed for interstellar travel [WIKI]

    and http://www.tauzero.aero/
    The Tau Zero Foundation is a global volunteer group of scientists, engineers, writers, and entrepreneurs working together to advance the goal of interstellar flight.
    Ad astra incrementis" means "to the stars in ever-increasing steps."

    My point is please don't use the follies of humanity and our problems on Earth to hinder, delay, or disrupt the progress of humanity.
    Those two horrible variable of politics and economics are all ready keeping a tight reign on what we achieve and where we are going, but I remain confident, that being "variables" good times are ahead and success will be achieved in time.
     
    Trippy and Ophiolite like this.

    As you know paddoboy the Like button only works once per post per member......and there isn't an "I Like This Very Much" button, but I did what I could.

    I'm all for safe space travel so let us proceed cautiously. Not having much to shield the travelers who travel years in space from cosmic radiation would cause severe body problems. Even on Mars there wouldn't be much going above ground if colonists were put there. I still think sending a craft to Mars and land it then return back to Earth would be a very important step towards future human space travel.

    That is part of the plan...You need to give NASA more credit.
    Think, Mercury, Gemini until finally Apollo...one man capsules, two man capsules and then EVA before Apollo, with three man capsules, orbital flights to the Moon and LM separation before the eventual manned landing and Apollo 11.
