A plan to create a greenhouse with aerogel to migrate Mars is devised

Use the materials that human beings already have.

The surface of Mars is too cold and not an environment where people can live at the moment.But if mankind creates a colony there, you need something that surpasses the cold and warms up.What should I do?

The key is "Silica Aerogel"

Currently, scientists can use the insulation substance called "Silica Aerogel" to create a part of the surface of Mars in an environment where photosynthesis like plants, for example, in a livable environment?Is proposed.This is assumed to be done in some land, not a terrifying plan for globalization of the entire planet.If this "aerogel" futon is laid in a frozen place like a skate link, the ice sheet will be easily dissolved to improve it into a rich land of water, and human and plants will live for a long time.It may be possible to do it.

Scientific Researcher Laura Curver in NASA's JPL (Jet Promotion Institute) told Gizmodo in the United States.

The method I've been thinking about terramating the planet has been too avant -garde, but this is not.

"Silica Aerogel" is not a radical scientific substance, but a small, expandable technology that already exists.Please see what it is actually like in the video.

Mars cannot be warmed

Humanity already proves that he is very good at warming the earth by using the greenhouse effect well.It means that, for example, a substance, such as carbon dioxide, absorbs and rebuilds sunlight, to warm the direct area from other places.

Nevertheless, it is impossible to warm the whole earth in this way.Past results show that current technology and Mars have sufficient carbon dioxide in terrain.So, as a matter of fact, scientists are trying to focus on how to warm up a small area as a research colony with as much effort as possible.

Effect of "silica aerogel"

"Silica Aerogel" attracts the greenhouse effect.This is a substance trapped in a net -shaped keys dioxide, mainly made of air volume, and thanks to its properties, a layer of thickness several centimeters has transmitted the visible light used by plants for photosynthesis, which is harmful.You will be able to block the ultraviolet rays and heat the lower part.

The research team created an experimental device that irradiates the same level of light as Mars, and measures the temperature difference between the top and bottom of 50 degrees or more.So I believe that such a material may help increase the ground temperature in the area around Mars.Therefore, Mr. Curver devised to create a tiled "silica aerogel" and assemble it in a greenhouse -like structure.

Evaluation of the surroundings

Some scientists, who are not involved in this study, describe this research as "smart" and "potentially interesting."

According to a comment on Gizmodo, Professor Bruce Jacosky of Colorado University, this method was "absolutely not terrifying", as claimed in other reports.However, instead, we propose to warm some areas so that the ice is melted.

However, a paper published by Nature Astronomy states that "there is a significant restriction that an important pressure for life cannot be overcome in the silica aerogel greenhouse", and Mr. Carber is "Silica Aerogel" is very fragile and polymer.It is pointed out that another material needs to be added.

Before that, the task was piled up

Nevertheless, we have to think a lot before thinking about terrifying a part of Mars.If you set up a base on Mars, there will be room for discussion about who will go there.

In addition, today's Mars may have its own life, so the existence of humans, plants and microorganisms will complicate Mars exploration.Mr. Carver also pointed out that if you terrain on Mars, the "untouched" environment you want scientists to investigate will be destroyed.

It may be cool in a small area

It's probably a bad idea to terrace on the whole Mars.Professor Jacosky says:

This is dangerous.It suggests that you can neglect the earth's environment.Not a good concept

But if you build a mechanism in a small area, not the entire planet, researchers may be able to perform experiments without potentially bad results.

First, I want to experiment on Earth

Eventually, this will be a study of concept demonstration.And the settlement of mankind on Mars is a distant uncertain future concept stage.But for now, researchers want to experiment with this substance in harsh environments on the earth, such as Antarctica and Chile.And unlike the uncertain technology used to change the entire planet, it is not so difficult to create a greenhouse from the existing substances.
