How to change the environment of Mars to make it more global?

Scientists put forward a new plan: five steps, Mars becomes the earth.

Scientists have put forward a grand plan: it takes only five steps, 1000 years, to turn the "red planet" of Mars into another earth with green mountains and green waters.

Step 1: Go straight to the theme "The Earth in an Alien Environment". According to Jublin's theory, the colonization of Mars will be divided into three steps. The first step is survey. We have already started, but we still need manned spacecraft to land on Mars to uncover the mystery of Martian mineral ice deposits and suitable living environment. Next, a Mars base will be built; Finally, make Mars a self-sufficient colony.

Now, it's time to start the global warming in the alien environment. We assume that the Mars warm-up project will be carried out in 2 150 years. To make Mars warm, we must first make it warm. Jublin described it as "restoring the warmth of Mars with the greenhouse effect". He put forward three sets of global warming plans. After careful analysis, Zhu thinks that the first two schemes are basically invalid, and the third scheme can be implemented although it is introduced roughly.

Step 2: Release gas from Martian soil species.

At least 3 billion years ago, the surface of Mars was covered by a thick carbon dioxide atmosphere. Now, although the soil has absorbed a lot of carbon dioxide, as long as the climate warms, it will be released. In other words, the climate on Mars is cold and annoying now, which absorbs all the gas into the soil, but if it is heated, it will usher in a "carbon dioxide feast".

In order to ensure the completion of the mission within 1000, Zhu said that the extra gas released from the Martian soil will raise the temperature by 10 degrees Fahrenheit in 20 years, and then some ice will melt, water will evaporate, and the climate of Mars will be initially improved. Considering these situations comprehensively, it is calculated that in the short 50 years from the beginning of the Mars geochemical project in 265,438+0.50 to 2200,

Step 3: Open the "Mars Garden".

In 2250, on the occasion of the 0/00th anniversary of Mars Geochemical Project/KLOC-,the first carbon tetrafluoride production plant will be officially opened. By then, the atmospheric concentration of Mars will reach 1/5 of that of the Earth: about 2 1@ and it will contain 20% carbon dioxide. By then, Martian residents will be able to take off their spacesuits and walk on Mars (although oxygen tanks are still needed).

Once the equatorial surface temperature of Mars is not lower than 32 degrees Fahrenheit, liquid water will appear on Mars, which also indicates that the "Mars Garden" can be opened. But Zhu warned: "First of all, maple trees must not be planted, and we should start with cultivating photosynthetic bacteria and lichens."

Although growing plants begin to convert carbon dioxide into delicious oxygen, there is a speed problem; If dead plants are treated like the earth, decay will release more carbon dioxide, thus slowing down the transformation process of carbon dioxide. Zhu believes that a solution should be found for Martian residents, and dead plants should be carefully treated to avoid the leakage of carbon dioxide.

Genetic engineering will also play a role in the transformation of Mars. Zhu hopes to cultivate plant varieties with super oxygen-producing ability through genetic engineering, so as to produce more oxygen.

Step 5: Wait 1000.

Everything seems simple: it takes 50 years to transform the atmosphere and 50 years for Mars to walk, but to make enough oxygen for Martian colonists to breathe, we have to patiently board 1000. During this 1000 year, Martian residents will continue to cultivate and harvest, play the role of "force of nature", speed up the transformation of carbon dioxide into oxygen, and create an atmosphere for human beings to breathe directly as soon as possible.
