The concept of "living in the present" may be advocated in life, but it is not very applicable to the development of civilization and the future.
In different periods of the development of human civilization, our obsession with the future is also different, but what we often say "living in the present" often deviates from our consideration of the future.
In the current development of civilization, scientists have explored Mars and Ceres: although Mars has certain habitable conditions, it is not suitable for human habitation due to the limitations of temperature, atmosphere, air pressure and other factors;
Ceres, on the other hand, exhibits more characteristics suitable for the existence of life and may become a new habitat in the future.
1. Suitability of Martian conditions.
Although there are certain habitable conditions on Mars, there are many reasons why it is not suitable for human settlement.
Since the "Ring of Fire" probe detected the radioactive elements of Mars in 1965, indicating that there may be a climate on Mars, the detection results of the "Mars Probe" have continuously refreshed our understanding of Mars.
The appearance of riverbed morphology, solid ice and other characteristics on Mars proves that there was indeed a large amount of water resources on Mars, but with the thinning of the Martian atmosphere, most of the water resources have been lost to outer space, and finally become a "mask" for Mars - an ice cap.
Until 2018, the exploration results of the Mars rover "Perseverance" showed that there were liquid salt water lakes on Mars, proving that there are still water resources on Mars, but this is only the residue of water molecules, which cannot support human habitation.
During the alternation of winter and summer, water molecules on Mars will also evaporate and enter the Martian atmosphere from the polar regions of Mars, but this is only a gaseous state of water molecules and cannot be a condition for human survival.
The air pressure of Mars is only 0.006 of that of Earth, so it cannot form the "greenhouse effect" on Earth, and as a result, the temperature on Mars is extremely low, and the maximum temperature is only 25 degrees Celsius.
In the summer, the temperature on Mars drops to minus 70 degrees Celsius, making it impossible to stay at the right temperature at night.
The atmosphere on Mars is very thin and cannot block cosmic rays, so people living on Mars will be attacked by carcinogens.
The atmosphere of Mars is so thin that the surface of Mars cannot form wind, and if there is a storm on Mars, it will endanger the life of the rover.
Second, Ceres is more likely to become a new habitat.
After Ceres was confirmed as a dwarf planet, scientists have been placed in a position where liquid water is suspected of existing, but in 2015, Ceres was detected, and the amount of water vapor on the surface increased by 300 times, and nitrogen also appeared, which indicates the existence of liquid water on Ceres.
Ceres is located in the third sphere of the solar system, so the amount of light received by Ceres must be moderate, and the amount of light received by Ceres is about 21% of the amount of light from the sun, which is relatively close to the amount of light from Earth.
The amount of light on Earth is 24% of that from the sun, does that mean that the amount of light on Ceres is the same as the amount of light on Earth?
The amount of light on Ceres is not the same as the amount of light on Earth, but it is undeniable that the amount of light on Ceres is definitely relatively modest, so that there is potential liquid water on Ceres.
On Ceres, scientists have also detected the presence of nitrogen, which indicates that the atmosphere on Ceres is still relatively thin, and nitrogen on Earth is one of the components of the atmosphere, which indicates that Ceres' atmosphere is relatively thin.
Ceres' atmosphere is too thin to form a "backup airbag" on Earth, so the amount of radiation on Ceres is larger than on Earth, but this amount is still acceptable.
Judging from the existence of liquid water on the surface of Ceres, Ceres and the Earth are not exactly the same conditions, but Ceres can give humans a living environment that leaves room for them, and it is also more in line with human living needs.
3. The reason why Ceres is suitable for human habitation.
Ceres is not far from the Sun, so Ceres receives enough light to keep liquid water present on Ceres, so that humans can survive on Ceres.
Ceres' atmosphere is very thin and can't create the greenhouse effect on Earth, so the temperature on Ceres is extremely low, but the amount of light on Ceres is very large, so it can maintain the temperature on Ceres.
The temperature on Ceres is so low that it does not allow the formation of atmospheric circulation on Earth, but there may be some small air currents on Ceres that block radiation on the surface of Ceres.
The air circle on Ceres is very thin, so that storms cannot form, and the safety of people living on Ceres is guaranteed.
The distance from Earth on Ceres is 320 million light-years, so this distance is very moderate for human beings and will not affect human life and development.
There may be liquid water on the surface of Ceres, which can prove the possibility of life on Ceres, but scientists have not found that there is life on Ceres, so scientists have a "suspicion" of life on Ceres.
The abundant resources on Ceres will make people's lives on Ceres more convenient and ensure a certain quality of life for human beings.
IV. Conclusion.
In the process of exploring new habitats, scientists should not only consider whether the position of the celestial bodies is appropriate, but also consider other factors, so that human life will become better in the future.
There are many more potentially habitable objects in the solar system, which have also been explored by scientists, and scientists will continue to explore outer space with other habitable objects to discover.
It is important enough that human exploration of outer space is not only about finding new habitats, but also about expanding scientific knowledge.
