"... Before talking about the specific plan to transform Mars, let's first briefly understand several main reasons about [Why can't Mars live directly]."

"We mainly classify these reasons into three points. Next, we will explain the general difficulties of these problems in order in a way that goes from simple to difficult."

At the same time, I saw an elderly aerospace expert wearing a somewhat old standard military uniform and a retirement level of 50 or 60 years old in his fifties and sixties.

Now, he is looking very healthy and rosy, and his overall mood is also a little excited. At this moment, he slowly told the key points about this matter to the outsiders and senior leaders in front of him who don’t know much about interstellar colonization:

"As for this most important first point... it is about the [atmosphere thickness] issue of this planet."

"The reason why most animals and plants on Blue Star can now grow and live freely on Blue Star."

"Instead of being blasted into the surface by high-intensity ionizing radiation emitted from the universe and the sun itself. The main contribution of most creatures to live like taking photos in front of X-ray machines every day is to attribute the thickness of the Blue Star's atmosphere itself to the standard."

"But it is natural to say that Mars, which is only 1% of the atmosphere of Blue Star, is a different matter."

"Don't dare to wear space suits and be on the surface of Mars. Try all living creatures that live hard, just wait for the cancer incidence index in your body to rise sharply!"

"Authentic, if you just want to avoid this problem simply and roughly, then choosing to build a city deeper underground to resist the high radiation that only impacts surface organisms, perhaps it is not impossible to adopt it."

"Only we have the [large-scale dungeon construction technology] that we will get from those Zion refugees and from the group of robot hosts in the Matrix world..."

"But I think all the leaders here should not want to see themselves spending so much effort to travel far to Mars to colonize. The main purpose of their descendants living in caves every day, and not daring to run to the surface to see the sunshine often, right?"

"If you only take care of the lives of those Zion refugees, you can handle it so casually."

"But if you want to let the descendants of the Long people live better... then this high radiation problem must be solved completely at this moment when you can open the crossing door on Mars at any time, thereby achieving the maximum saving of transportation costs of various facilities and materials, and the best experimental opportunity to accumulate experience after repeated trial and error, and completely solve it!"

"The way to solve this problem is closely related to the second problem we will talk about next..."

Speaking of this, the old astronaut who held the remote control and pressed the button lightly, made the projector located in this conference room play the screen from the "Comparative Structure Map of the Mars atmosphere and the Blue Star atmosphere" originally projected on the curtain to another "planetary profile structure map" describing Mars' to the Blue Star...

The man slowly picked up a cup of boiled water from the podium, took a sip of it, and then continued to start his long speech in another breath:

"The second problem closely linked to the problem of [atmosphere thickness] is [magnetic field]."

"The main reason why the Blue Star's atmosphere can form a 'galactic cosmic ray' released from the universe itself and the 'coronal matter ejection (CME)' emitted from the sun can be summarized as 'high-energy radiation' problem... are all because the Blue Star's magnetic field itself is quite stable."

"A stable planetary magnetic field can not only withstand most high-energy radiation strikes transmitted from the universe."

"The key point is that this thing can 'lock' the atmosphere of the planet, so that the atmosphere itself will no longer be directly blown away and lost by the solar winds that are trying to rush into the surface all the time."

"As long as the magnetic field is completely stabilized and the Martian atmosphere is no longer in a state of loss all the time, we can continue to try to continuously heat up this cold planet with a surface temperature of minus 60 degrees Celsius on that planet, by building a large number of greenhouse gas factories that specialize in the production of 'carbon tetrafluoride' on that planet, and continuously try to heat up this cold planet with a surface temperature of minus 60 degrees centigrade all year round!"

"According to the calculations of professionals... If 1,000 tons of this gas is emitted per hour, it will only take 30 years to increase the average temperature on the Mars surface by 27.8℃."

"This process is expected to consume up to 5,000 megawatts of energy, and only 5 fission nuclear power plants can meet these energy needs."

"Because we can now start large-scale infrastructure on the spot through a very convenient crossing gate... the next test time on Mars in that different world will not take as long as thirty years."

"And as the temperature of Mars continues to increase, the large amount of carbon dioxide frozen on the ice caps of the two poles of Mars and the carbon dioxide in the soil will be released, causing the overall temperature to be increased on a small scale."

"If we are willing to invest huge costs at all costs, then it will take only a few years to completely increase the surface temperature of Mars to zero!"

"Once Mars' annual average surface temperature rises above zero, the chain effect will become more and more after that..."

"Not only some ice sheets located in the equatorial area will re-melt into a large amount of liquid water, and thus bring sufficient stable water resources to the residents living on this planet."

"The common climate of blue stars like rain and snow will also appear as the planet's water resources gradually increase."

"As long as we work harder during this period, we will start to let those tireless NS-4 robot laborers launch large-scale mechanized tree planting activities, and then cultivate more super plants that can release oxygen for this planet - then this is the vast majority of the atmospheric components that are originally dominated by carbon dioxide, and will naturally be infinitely close to the air components on the Blue Star!"

"At that time, it is expected that in about ten years, the atmospheric content on Mars will reach one-fifth of that of the Blue Star."

"It's enough that all residents can walk freely on the earth of this planet without wearing any space suits!"

"... Of course, if you walk in a wilderness area with non-vegetable density, you must have a simple oxygen bag with you to maintain your daily breathing."

"But compared to the days when we have only been living in the ground holes in the past we have immigrated, this kind of living situation where we can walk and breathe freely without equipment in surface residential areas in a short period of time, and even if we go to non-residential areas, we only need to bring an oxygen bag to maintain our daily existence. It is already a very ideal living environment!"

"What's more, this atmospheric component is not static."

"As long as we produce NS-4 robot factories, we continue to increase production efficiency day and night, and constantly organize them to continue planting trees in wilderness areas... this is probably within a few decades, and we can completely complete the power of everyone to breathe freely on that planet."

"The overall appearance of the entire Mars at that time will also become infinitely close to the blue star landform we live in now."

"The fundamental reason why all of the above looks good is how to activate this planet, which is only one percent weak magnetic field of the Blue Star."

"If there is no stable magnetic field, no matter how much greenhouse gas we can put on the surface of Mars in another world by putting on the Blue Star in the real world, the result will undoubtedly be completely blown away by the solar wind that is constantly blowing to the surface of Mars!"

"The magnetic field problem of this planet undoubtedly determines whether this colonial star, which seems to have infinite potential, can be completely conquered by mankind!"

Immediately afterwards, the old aerospace expert noticed the excitement that everyone at the scene was immediately mobilized by his speech, and tried to react to the interruption...

The other person who picked up the water cup and took a sip, but still did not give them this opportunity at all. He continued to press the remote control button that adjusted the projection screen, and began to explain his unfinished speech on his own:

"...and if this magnetic field problem is the main issue that concerns whether humans can survive on the surface of that planet in the future."

"The third problem I mentioned next, that is, the last one, is related to whether our descendants can successfully grow on this planet..."

"As for the name of this question... it is [gravity]."
