Should we colonize Mars?

One of the main issues that needs to be discussed is whether Mars contains a local form of life - and how will this affect the question of whether to build a colony or colonize Mars?

As we continue to explore the solar system and beyond, the question of making another planet habitable and colonizing comes up more and more. Manned colonies on the moon or Mars have been a long-standing dream for many. There is a natural desire to explore as far as we can, as well as to expand the human presence on a permanent or semi-permanent basis. To do this, it will be necessary to adapt ourselves to extreme environments. On the moon for example, the colony must provide at least most of its needs and protect the inhabitants from the void and the harsh environment outside.

Mars, however, is different. While future bases will be able to adapt to the Martian environment, there will also be the option to adapt to the external environment instead of just getting along with it. This is the "nationalization" process terraforming that eventually the atmosphere of Mars will become similar to that of the Earth. Although there is still a lot to focus on technologically, earthing the red planet seems like a possible future, but the biggest question is, is it worth doing?

One of the main issues that needs to be discussed is whether Mars contains a local form of life - and how will this affect the question of whether to build a colony or colonize Mars?

If Mars has any kind of biosphere, it should be preserved as much as possible. We still don't know if such a biosphere exists, but the possibility in the meantime has only increased thanks to recent discoveries, and it must be taken into account. Such a rare discovery, which can teach us about the way in which life was created in both worlds and therefore it is forbidden to destroy the existing one.

Small colonies would be fine, but life on Mars should not exist at the expense of any local habitat, if it exists. The most likely place to find life on Mars is underground. If the surface is as sterile and barren as it seems, then establishing colonies there will not be a problem.

Some have proposed to maintain human life inside caves on Mars, which would serve as a natural protection from the harsh conditions on the ground. True, but it seems that someone else lives in them, and that you should avoid disturbing them. If Mars is home to local life forms, the possibility of colonizing it should be ruled out.

But what if Mars is lifeless? Even if no form of life exists there, still the primordial alien environment from which we have so far scraped only a little needs to be preserved as it is as possible. We have already done enough damage to our planet. By studying Mars and the other planets and moons in their current natural state, we can learn much more about history as well as learn about our world from this context. We need to appreciate the differences in the variety of worlds instead of just making them fit our ambitions.

And of course there is the problem of contamination. For a long time there has been a protocol, in accordance with the Outer Space Treaty of 1967, according to which all spacecraft flying to the Moon and Mars will be sterilized as much as possible. If a bacterium from Earth makes its way to the surface of Mars and survives it may complicate the search for life there. If a lander or rover later detects life on the ground, it will be difficult to determine whether they are microbes that have contaminated Mars or whether they are original life forms.

Both scientifically and ethically, it seems sound and prudent to try to protect Mars as much as we can from invaders from Earth. This matters whether Mars is already inhabited or not. Fortunately, for almost any type of bacteria or other micro-organisms from Earth, it would be difficult if not impossible to survive on the surface of Mars let alone thrive. The risk of total contamination of the planet is negligible, but it is still better to take preventive measures than to play with luck.

Astrobiologist Chris McKay recently published Article And in it other points of view from this article about the question of whether Mars should be protected and prevent at all costs the damage to the fragments of life.

"Mars ecosystems have been seriously debated within the field of planetary science. It seems that maintaining a thick atmosphere on Mars and creating a good environment for life for many life forms is possible. It is now essential to consider how to do this. To do this will require us to enter new and interesting territories in the field of environmental ethics both from the utilitarian and the essential point of view, it is worth discussing the issue to support the concept of planetary ecological systems. A direct argument of conservation is irrelevant. It is important that we have a long-term view of life on Mars and the feasibility of merging between the environments. This will affect the way we study Mars today. Mars may be our first step into the biological universe, it's a step that should be taken with caution."

  1. There are other reasons such as:
    1. Nuclear holocaust
    2. A meteor that falls on the earth
    3. Mega volcanic activity like from Yellowstone Park in the USA which will put the earth into a new ice age
    4. Gamma rays directed at a nearby supernova
    Did I forget anything?

  2. In a few decades, Kadaha will suffer from a population explosion. If we don't make planets protest like this, our descendants won't have a living space.

  3. Geological evidence of fossils tells us about photosynthetic bacteria from 3.9 m years ago that started the process of creating life on Earth.
    The presence of methane gas on Mars suggests life below the surface that produces these gases.
    The ALH84001 meteorite from Mars also suggests the presence of magnetotactic bacteria.
    Transplanting similar bacteria that exist on Earth in environments that are comfortable for them such as at the poles or under the surface of the ground and of course help in creating an atmosphere will speed up the colonization of Mars.

  4. I'm trying to think of a reason not to try to enthuse him and I can't find one,
    You have to take organisms that live at extreme points on Earth (boiling springs, frozen poles, etc.),
    to put them all, in combination with lots and lots of bacteria and life from the earth and of course a substrate on which they can exist for a good few years,
    and find a way to let them find their way on Mars.

    Worst of all, we lost a spacecraft, a lot of bacteria and really expensive compost.

  5. It turns out from the research of the probes that explored and are still exploring Mars that there is a large amount of ice there and there was a flow of streams and channels carved into the rocks there.
    In addition, there was extensive volcanic activity there that stopped in the past.
    Regarding living there, they are currently working on independent environmental systems that economize themselves and are tested in the desert in the USA.
    There is also the possibility of living inside excavations for protection from radiation and the elements.

  6. The book Red Mars talks about the subject in detail. Highly recommended for those interested.

  7. A thick atmosphere like the earth can also, for example, bring about terrible storms that will make the delay there
    very difficult and dangerous perhaps no less than the current situation, and in all likelihood it will reach a self-balancing bank that is not comfortable for us,
    Reaching the balance of an atmosphere that will be similar to the Earth is an extremely complicated thing,
    The mass of Mars is small and does not have the same gravitational force as on Earth
    There is no magnetic protection only only these 2 issues can be fatal for human life and their proliferation over time,
    Its distance from the sun is different, it does not have a massive moon like ours and it is not clear how much water is there
    Is it oceans on earth that share the balance of the weather, no volcanic activity, no tectonic activity,
    The Earth's weather system is of tremendous complexity
    It's not just that you have to run it on supercomputers to get a picture of its behavior
    And even today, you always want a more powerful supercomputer to create a more accurate simulation because
    The enormous amount of variables and the huge and complex number of connections between its various components,
    The weather forecast we receive is with a percentage chance that its accuracy is getting smaller in future prediction
    There are disagreements about almost every element of the weather (also because it is related to economic interests - it was already written on this site)
    And when some general agreement is reached on a trend, then the discussion begins as to what causes this trend.
    It is likely that in the future if humans continue to develop they will be able to shape a planet like Mars into something
    The question is whether this something different will need constant intervention to stabilize it
    Because it is possible that without the elements present on Earth the atmospheric system will self-balance at another point
    And only with constant intervention that compensates for a lack of those components will it be possible to create something reminiscent
    the atmosphere and the weather we know

  8. There was an idea to set up something there that played off the warming that is here in Kedova.
    But even if we manage to reach Mars and establish what is needed there it will still take more than 100 years.

  9. There are several points to consider:
    1. If there is any life there, do not contaminate the spaceships that return to Israel with these bacteria
    2. Technology is required that pours the ice that exists there into water and hydrogen, water for drinking and irrigation and hydrogen for energy
    3. Develop algae and bacteria that know how to extract oxygen and carbon dioxide into the atmosphere from the rocks and ice
    4. To consider bombarding the high volcano there with a hydrogen bomb to renew its activity if there is still any, as well as bombard the poles with ice to vaporize them and create clouds.
    5. An independent system technology is required that will work first on Earth in the desert and then on the Moon and then on Mars.

  10. Hen, you're wrong, the temp doesn't reach 150 degrees during the day, but stays below zero, so you can't walk around in a short shirt. Besides, the atmosphere there is toxic and you really shouldn't breathe it. Moreover, the atmospheric pressure is very low: your eyes won't pop out (like in the movie "Fateful Memory"), but your blood will start to boil, and it can be assumed that you will start bleeding from all kinds of interesting places...

  11. To my father, the article is very interesting, and there will be many such articles. I personally think it should be between
    The main goals of the world, because we need more resources and an alternative to the like.
    I hope that following the sending of the Curiosity spacecraft, positive news will be revealed and that Mars will be a subject
    that we can talk about it in our agenda.

  12. melody
    It is advisable to learn the conjugation of verbs in the first person future:
    Not "I can" but I will.
    Not "I will take" but I will take.
    You repeat the errors and you should standardize.
    rationalize
    Mainly “and such” …..

  13. Hi Chen, really a good and important question. In my opinion, the other contestants will not really bring peace and security and only Mars will regulate our economy, therefore Mars is my candidate for the Knesset.
    Mars, good for Jews. - Put "ma" in the ballot box

  14. Hey,

    Several MDV books have been published on the subject of the Earthing of Mars, in my opinion we must prepare an alternative to the Earth - meteors and such.

  15. A question that intrigues me
    The temperature on Mars ranges from about 150 degrees during the day to about -150 degrees at night.
    Can I theoretically find a point in time when the temperature will be comfortable for me, and then I can wear a short shirt and have fun walking around? (Ignore the radiation issue for a moment, and I'll take a deep breath), although there must be differences in atmospheric pressure and my blood will boil immediately, what do you say?

  16. I would suggest that we start by stopping destroying Earth before we try to "fix" other planets

  17. If anything, then we are not working to redefine it, but to eliminate it.

    600 degrees in the shade... not bad.

  18. If we shut down the earth, nip Uranus, and negate Mars, then maybe we can justify Pluto's land by his mother-in-law.

  19. There was no free oxygen in the beginning either. It took blue bacteria to land on Earth and at least several tens of millions of years, but they succeeded, and will succeed on Mars as well, hopefully in a shorter time.

    The question is whether they will even succeed in creating an atmosphere and preserving it, because it seems that the atmosphere that Mars had in its early period was eroded by the solar winds in the absence of a magnetic field for Mars.

  20. In the end they will glorify Mars, the question is how long it will take until they reach this decision.

    And this is a relatively cheap way
    By bombarding the star with bacteria suitable for each and every stage.

    If there is a trace of life in the depths of the earth, they will rise up.
    But it is more likely that there is no life there at all, because if there was life there they would find their way out in any situation, thrive and change the atmosphere with enormous speed and force.

    The decision to colonize Mars will eventually come after the contamination of the planet with germs from Earth.
    It is impossible to study the planet for a long time in absolute sterility.

  21. First it has to be proven that there is no life there,
    Let them not prevent us from introducing life from Earth there...

  22. STNG HomeSoil
    TNG created the world as we know it
    Might as well watch it and learn oh Juda Juda JudaJuda nanana-nananana

  23. Until you start "ruining" some kind of planet, you'd better repair the damage done to the local biosphere...

    Earthing of Mars is possible with the encouragement of the "greenhouse output" there and the development of algae that will convert the CO2 there into oxygen and organic matter. Another problem is the lack of a protective magnetic field.

  24. I don't understand how it would be possible to colonize Mars. Where will a huge amount of oxygen be found to energize it?, and I'm not talking about water. We might be able to drop some giant comet containing water to Mars, but even that would be a difficult problem.
    But if it is about establishing a colony on Mars for research purposes, that is a completely different matter and the cost will only be a few hundred billion dollars. Is this worthwhile?, I doubt it.
    And by the way, here on the science website I proved in an article that the first colonies on Mars will be conducted in caves. There is absolutely no need to bring buildings from Earth. And it's not just those that need to be organized for living conditions even before the first residents arrive.

    I regret to say that the article is from the period when I was approved to submit bold articles to the journal
    Good night
