In March 2021, in the desert area of Mars, a European Space Agency Mars orbiter flew above Mars, its name is "Mars Express-1", which is the first orbiter in Europe to explore Mars.
After observing Mars, the spacecraft not only found craters and traces of water in craters on the surface of Mars, but also found that there are a lot of water resources under Mars.
These water resources are enough to cover the surface of Mars and paint the surface of the earth in water blue, which can be called "150 Bohai Seas on Mars".
This water is enough to sustain humans on Mars for 200 years, allowing humans to turn the Martian desert into an oasis and make life comfortable on the giant Red Planet.
These discoveries have sparked the imagination of whether it is possible to establish a permanent human settlement on Mars.
ESA has discovered a large amount of water resources on Mars.
In 2003, the European Space Agency launched the "Mars Express-1", which was the first time ESA explored Mars, but because there is a huge "blank area" between Mars and the Earth, this interval is called the "solar radiation zone", which is filled with a large amount of dangerous solar radiation, which will cause damage to the equipment on the spacecraft and endanger the health of the astronauts on the spacecraft.
In order to prevent the astronauts' bodies from being harmed, ESA chose to send an unmanned orbiter to explore Mars, but because of the huge space between Mars and the Earth, ESA's unmanned aerial vehicle will pass through the solar radiation zone during the flight to Mars, so in the process of flying to Mars, ESA's unmanned aerial vehicle needs to wrap itself in a shell to prevent the harm caused by solar radiation to the spacecraft.
When the spacecraft flies through the solar radiation zone, the ESA spacecraft will enjoy a leisurely and good time in the shell, and the equipment in the spacecraft will also suffer from the tempering of time in the good time, just as people are easy to get fat after being immersed in a beautiful and lazy life for a long time, and the equipment in ESA's spacecraft will also have some defects due to a long period of non-work.
When the vehicle will enter the Martian atmosphere, the shell will lose its ability to resist solar radiation, and normally, the shell will be thrown away by the spacecraft, and then enter the Martian atmosphere to complete ESA's Martian observation mission.
However, in 2003, ESA's Mars Express 1 lost contact with the spacecraft after it entered the Martian atmosphere, making it impossible for the spacecraft's equipment to complete the Mars observation mission.
Mars Express 1, launched in 2003, was still floating in the Martian atmosphere after the vehicle lost contact, and in 2004, as Mars Valiant landed on the surface of Mars, a huge parachute opened from Valiant and robotic arms extended from the parachute in an attempt to grab the information-gathering equipment in Mars Express 1.
However, when the robotic arm was operating the 2003 Mars Express-1 device, the device suddenly had a problem, causing the robotic arm to be unable to accurately grasp the device, and eventually the robotic arm only grabbed a part of the Mars Express-1 and could not return it to Valian.
Although the Mars spacecraft in 2003 could not observe Mars after entering the Martian atmosphere, the outer protection mission it completed made it still complete the observation mission to Mars in 2004, and the Mars Express 1 in 2003 was abandoned in the Martian atmosphere.
The Mars spacecraft in 2003 was abandoned in the Martian atmosphere in 2004, but before the robotic arm could be pulled back into Valian, it took pictures of the situation on the Martian surface.
After the Mars Express 1 lost contact in 2003, scientists speculated that it had not survived solar radiation, so scientists abandoned the Mars Express 1 in 2004 after the robotic arm could not pull it back.
In 2004, the robotic arm was unable to pull back the Mars Express 1, which was abandoned in the Martian atmosphere, and Mars Express 1 gradually moved away from Mars and traveled beyond the solar system.
After the departure of Mars Express 1 in 2004, ESA launched a new Mars exploration orbiter to Mars in 2016, and ESA named the new spacecraft "Mars Express 1".
After Mars Express 1 arrived on Mars, it not only found craters and traces of water in craters on the surface of Mars, but also found a large amount of water resources below the surface.
150 Bohai on Mars.
Through the study of Mars, ESA found that the water resources under the surface of Mars are very rich, from 0 to 10 meters deep on the surface of Mars, there are 3.6×10^6 cubic kilometers of water, the amount of water resources is comparable to the Bohai Sea on the continent, which is equivalent to 150 Bohai Seas on the surface of Mars.
If the surface of Mars is submerged with this water, then the height of the water is enough to cover the surface of Mars with water 2 meters deep, and the carbon dioxide in the Martian atmosphere can be frozen, which can reduce the temperature of Mars, so that the water generated on Mars can reach the surface of Mars, turning the surface of Mars into an oasis.
The 2003 Mars Express 1 was originally intended to explore Mars' water resources, but because it lost contact in the Martian atmosphere, ESA did not have a new spacecraft to explore Mars.
With ESA's Mars Express 1 launched in 2016 to explore the water resources on Mars, ESA scientists have found a certain connection between the carbon dioxide ice in the Martian atmosphere and the water resources deep on the surface of Mars, and it was in the atmosphere that American scientists observed in 1947 when they observed Mars.
As ESA scientists increasingly discover the existence of water on Mars, more and more people are seriously considering whether humans can survive on Mars.
Is it really feasible to survive on Mars?
From ESA's observation of the water resources on Mars, the water resources on Mars are abundant, and it is completely feasible to use the water resources on Mars to turn the Martian surface into an oasis, but there are many problems in applying this scheme to reality.
Turning the water resources of Mars into an oasis requires humans to build a robot that can dig water to the surface, but the performance of this robot is difficult to make.
The biggest problem of the current robot is that it is very noisy when it is running, just like the bottom of the wok will make a "crackling" sound when cooking, and the robot will often make the sound of metal collision when operating.
If humans build a robot that can dig up water resources under Mars, then when the robot excavates groundwater resources, it will often make metal collision sounds, so the robot will be very noisy, which will have an impact on the carbon dioxide ice in the Martian atmosphere.
If it's too noisy, it can have a huge impact on the carbon dioxide ice, causing it to fly away from the atmosphere and eventually create a water-blue atmosphere on Mars.
epilogue
Therefore, ESA must be very careful not to allow the spacecraft or robotic equipment to come into direct contact with the water resources and avoid the disappearance of carbon dioxide from the atmosphere.
At present, the survival of human beings on Mars is still in the stage of feasibility study, but the existence of such abundant water resources on Mars provides favorable conditions for human survival on Mars.
