Vol 2 Chapter 1062: There is no harm without comparison!

She happily moved her hand across the green glass jar in the entire cabin and said: "So our company laboratory carefully screened several cyanobacteria with the most outstanding oxygen production capabilities, and let them follow us to experiment in space.
In this way, we can experiment with a longer period of time, a longer distance, and more space environments to test out what kind of cyanobacteria can more adapt to the complex and harsh space environment.
If we want to survive and work on Mars for a long time in the future, there must be a variety of stable and continuous supplies of oxygen, which is what we must have. The oxygen brought from the earth is definitely not long enough. Yes, even if our company's carrying capacity is too great!
After all, we will have to find ways to be self-sufficient on Mars for a long time in the future. Not only we astronauts need oxygen, but our animal-breeding experiments also require a large amount of oxygen and food resources.
Just relying on planting plants to obtain oxygen and food, then you can simply calculate how much planting space and breeding space are needed to ensure our survival. Obviously, it is impossible for us to use such precious development space to do this in the early stage. !
Take the cyanobacteria in this glass jar. It is called spiral cyanobacteria. It is a cyanobacteria that naturally grows in tropical lakes and marshes. It releases oxygen more effectively than grass and trees.
As long as it is cultivated in 6 liters of culture medium, it can produce the oxygen that a person needs in a day.
The cultivation method of this spiral cyanobacteria is very simple. As long as there is sufficient light, the water temperature is kept at about 30°C, people often exhale carbon dioxide to it, and regularly add some nutrients such as nitrogen, phosphorus and trace elements.
What's more striking is that it is rich in nutrients necessary for the human body. In particular, protein is very rich, in addition to this, the content of various vitamins, minerals and other nutrients is also very balanced.
It takes about 6 hours to double it, so it can be collected continuously every day. It can be used not only as a source of oxygen for humans, but also as a nutritional supplement, or to make natural fertilizers or food for animals, and has high utilization value.
In the future, we will also select some of these blue-green algae that are more adaptable to the space and Martian environment for large-scale cultivation to support our various needs on Mars! "
Seeing this, many netizens have begun to lament that it is not easy for humans to colonize alien planets. It takes so much trouble to colonize the planet on the nearest planet, let alone farther away.
Especially many netizens from the United States have begun to complain about paying the IQ tax, because many of them have been deceived by the space exploration company and other companies that promote the colonization of Mars!
Even Infinite Gravity Group needs so much preparation to start the Mars colonization exploration work, how can their companies dare to brag about their Mars colonization plan?
Some of them paid the registration fee, and some even paid more upfront fees, but now it seems that the money is probably in vain.
Even if someone has analyzed the situation they will face before, they are still reluctant to believe it before the Mars orbiting space station of the Infinite Gravity Group's ‘Horse Guardian’ Mars orbiting space station has announced the relevant situation.
Mars is at least 55 million kilometers away from Earth. According to previous human space technology, it will take at least 7 months to get there.
The "Mars One" company previously launched a "go and no return" Martian immigration plan, intending to send the first immigrants to Mars in 2023. At that time, this plan caused many professionals to question and were accused of being unreliable.
According to calculations based on some data, this plan can only allow humans to survive on Mars for 68 days. Therefore, this plan has been sprayed by many people without skin.
A five-person research team used data from the "Mars One" space launch company to analyze the mathematical formulas of oxygen, food and technology required for human migration to Mars, and completed a 35-page report.
It is believed that in view of the conditions on Mars and the limitations of existing human technology, the "Mars One" company's migration plan to Mars is impossible to achieve.
According to the report, if it does migrate to Mars, the plants brought from the earth can only produce an "unsafe" amount of oxygen, and the oxygen content will begin to run out in about two months. "In about 68 days, the first death may occur. ".
The researchers said that if humans want to settle on Mars for a long time, new technologies are needed, "some form of life support system is needed, which is a technology that has not yet been developed in space flight."
In addition, transporting spare parts from Earth to Mars is also a challenge, which will increase the cost of immigration to Mars.
And space exploration companies are also making ambitious plans to land on Mars and launch colonization operations. In their company's Mars colonization concept, the core part is the reusable rocket-spacecraft combination. The company founders care about it. It is called the "Interstellar Transportation System".
Both the propeller and the spacecraft are driven by SpaceX's Raptor engine, which is still under development. According to their published data, it will be three times stronger than the Merlin engine. The Falcon 9 rocket is driven by the Merlin engine.
The thruster contains 42 Raptors, which will be the most powerful rocket in history so far. When the rocket is launched, it can load 300 tons of materials and send it into low-Earth orbit. If it is a consumable material, the load can reach 550 tons.
But even a spacecraft of this size ~ EbookFREE.me~ its load scale is only about one-twentieth of the Mars orbiting space station of the Infinite Gravity Group's "Wandering Guardian", and such a spacecraft , The space exploration company actually wants to carry at least 100 people!
A comparison shows how unreliable this number is. There is really no harm if there is no comparison. Infinite Gravity Group's space station combination with such a large tonnage can carry up to 16 astronauts. There are various safety and Prepare to survive to ensure their survival after arriving on Mars.
And even if it is calculated according to the maximum starting weight of 550 tons announced by the Space Exploration Company, excluding fuel and other various materials, such as food, water, oxygen and other materials necessary for human survival can have a 100 tons, even if it is more. ?
Calculated according to this amount, on average, each person can only be allocated a ton of such survival materials. It seems that one of these materials can be used for a while.
But after more than half a year of voyage consumption, how long can these materials allow these people who dream of colonizing Mars to survive on Mars? This number may not be much longer than the "Mars One" company.
