For years and decades now the concept of terraforming Mars has kept researchers and science experts on their feet scratching their heads to find a solution. This enthusiasm came from various fictional novels and movies that have given scientists hope that perhaps they can implement this idea. According to research, Mars has the potential to be humanity’s second home and they are trying to make this concept a reality.

If Mars is ever to be terraformed, it will be a monumental task. Terraforming Mars could take decades or even centuries in its initial stages. Additionally, we do not have the technological capacity to implement this initiative. This sobering realisation highlights the enormous obstacles that stand in our way of realising the aim of altering the Red Planet. NASA needs to reassess the grand dream of Terraforming Mars

The dream or vision of making Mars a planet that can give life to humanity is an interesting one. This concept has been part of scientific language and conversation for decades now and it promises not to just give humanity a different perspective, but, also to serve as plan B as the Earth is changing. Scientists have hypothesised that humanity may establish conditions conducive to human life on Mars by releasing greenhouse gases and altering Martian.

NASA has admitted to this impossible mission stating that It is not possible to terraform Mars with current technology. Mars’ thin atmosphere and deficiency in vital resources such as enough carbon dioxide that would be required to start a greenhouse effect and warm the planet are the main obstacles. The idea of converting Mars into an environment more like Earth is significantly more difficult than first thought due to the harsh reality of the planet’s current status.

Therefore, the issue is not entirely based on technology, but also based on the enormity of the resources needed. Less than 1% of Earth’s atmosphere is found on Mars, and the planet does not have a magnetic field to shield it from cosmic radiation. It is therefore a wise idea for scientists and researchers to discard this idea since reports state that it could take thousands of decades to implement this idea. Unless a new technology advances enough to take on this big idea. Obstacles on the journey to a habitable Mars: Scientific, material, and time

Mars does not have the nature or resources that are similar to Earth that can even give us hope. If it comprises less than 1% of what the Earth attributes, then it could be a waste of time, resources and investments. Due to the abundance of carbon dioxide in our atmosphere (earth), heat is retained and a rather stable climate is produced. Mars’s sparse atmosphere prevents the planet from efficiently retaining heat.

According to Bonsor (n.d.), NASA is reportedly developing a solar sail propulsion technology that would harness solar energy to power spaceships through the use of enormous reflective mirrors. Placing these massive mirrors a few hundred thousand kilometres away from Mars would be another way to use them: to heat the Martian surface by reflecting solar radiation.

NASA has found that, even in the event that all of Mars’ CO2 could be released, the atmospheric pressure required for human survival without a spacesuit would not be produced. The entire accessible carbon dioxide is insufficient to generate a habitable atmosphere, and transferring more gases from Earth or other celestial planets is currently beyond our technical capabilities.

The lack of a magnetic field on Mars presents another significant difficulty. The Earth’s magnetic field is essential for protecting the world from solar winds and dangerous cosmic radiation, which would otherwise remove our atmosphere. Mars has a thin atmosphere now because billions of years ago, the planet lost its magnetic field. It is just not possible to build an artificial magnetic shield using the technologies available today in order to terraform Mars.

The idea of terraforming may not be fully realised for several millennia, even though humans might visit Mars this century. It took the Earth billions of years to develop into a planet on which plants and animals could flourish. It is not an easy task to change the Martian landscape to resemble Earth. To create a livable environment and introduce life to the icy, arid planet of Mars, generations of human creativity and labour will be required (Bonsor, n.d).

What nature?

Far as we know,Mars is a dead rock. I agree that we should preserve hypothetical alien lifeforms,but what nature are we ruining by making an empty place livable?

As far as we know! There could be some extremely basic form of proto-life surviving off of minerals and radiation, or remnants of now extinct life when Mars had water, and that would be destroyed by terraforming.

Also? Geology (areology in Mars's case) has scientific value and helps us understand the universe. Who knows what kinds of things we might discover in the Martian crust? We can learn so much about how planets form and about the ancient history of our solar system. Rocks aren't worthless.

And there's an aesthetic and cultural value to preserving the ancient landscape. It's not "just" a rock anymore than mountains are "just" rocks. Shall we knock down the buttes and fill the canyons with concrete just because they're rocks?

Keep Mars red!

I can see your point,but that doesn't seem enough to just not settle any planetside areas because we'd "upset the natural scenery".

I mean,I won't oppose anyone who would want to live on Mars in the far future just because the environment would change.

I dunno,I never jived with the perspective that humans are supposed to just not interact with foreign environments and keep them in some sort of glass case only out of some weird quasi religious deference to "Mother Nature".

Obviously,if we have the means,we should exercise extreme caution,but to flat out refuse to settle any planet other than this one seems silly in my opinion.

We don't do it for some metaphysical "Mother Nature" but for each other. Defacing Mars would be robbing humanity of the natural beauty of the Martian landscape.

Mars has it's own beauty that we can learn to appreciate, I think terraforming would rob us of the chance.

I just think that it shouldn't be all forbidden.

Humanity can preserve sections of it for aesthetic or scientific purposes,but if it's more cost effective than building an orbital arcology,then I would be in favor of that. I see it like this,we should prioritize the needs of human society first over preserving natural landscapes in the case where it would help us develop technologically. Again,with the caveat that all necessary precautions are taken first.

I understand your point about the value of things as they are to human science and society, but I personally think our needs should be put first in the purely hypothetical scenario where we can interact with with foreign planetary bodies. Also, wouldn't terraforming offer valuable scientific data about how to curate and develop an ecosystem from the ground up? The Earth and other potentially habitable planets offer plenty of information, but wouldn't some direct practice be also needed to create proper orbital ecosystems?

I would also like to point out that I am no where near an expert in biology or geology and I'm merely expressing the perspective I have with the limited information I have. I take full ownership of any lapses in my judgement and I will be the first to admit that whatever discrepancies there are in my beliefs are most probably caused by the limited knowledge I possess.

Don't get me wrong,I'm no Muskite,and I wouldn't lose any sleep over Mars staying the same,but if it's deemed more efficient to terraform Mars over building orbital arcologies,I would back that policy.

My apologies for misinterpreting your sentiment,I just have a dislike for the people who act like we should swear off all development in the name of some idealistic notion of us being "caretakers" or "guardians" of nature because it just seems to be full of hubris. I see now that is not your position,and I want to clarify I didn't intend to come off in a hostile way.

Oh I don't disagree! The natural world and the artificial world are in a dialectical relationship, one can not exist without the other. It seems entirely possible to reach a synthesis.

Forbidding humans from setting foot on Mars is pointless anyway, if it's possible then it literally can not be truly forbidden because people will go there no matter what. People trespass in the Chernobyl exclusion zone, they'll trespass on Mars too.

We've already disturbed the ancient landscape with our rovers anway, even if we painstakingly undid the damage it wouldn't really be natural. It'd just be an artificial rehabilitation.

Humans can have a little bit of Mars, as a treat.
