How can it be deduced that there is not only water on Mars, but also oxygen?

Our current research on Martian soil and rocks suggests that there may be water and oxygen on Mars. Our exploration of space has never stopped. Mars is a relatively close star to us, so we have studied it a lot.

Our research on stars in space generally focuses on the presence or absence of water and oxygen on the planet. Because if these two conditions are present, then there may be life this week, or it can be inhabited by humans.

Many riverbeds have been found on Mars, as well as the imprints of water currents. When we explored Mars, we found that there are some ancient riverbeds on the surface of Mars and traces left by the impact of water currents, which suggest that there may be water on Mars, and a large amount of water. As for the water on Mars, this is our next research direction.

The presence of water on Mars is a big step in our discovery of Mars. And that's why we came up with the "Migration to Mars" program.

The material extracted from the soil of Mars indicates the presence of water and oxygen on it. We're going to bring back some soil and some rocks from Mars for study. We found some substances in it, and this substance can only be formed in the presence of water and oxygen.

This is also an important reason why we believe that water and oxygen have existed on Mars. And we found that Mars has the shadow of a building on it, and it is very similar to the shape of a pyramid. Does this mean that there was life and civilization on Mars, and it is also a proof that there is water and oxygen on Mars.

Our research on Mars is still ongoing, and as we continue to explore, these questions will be further solved. Therefore, with the development of science and technology and the improvement of civilization, one day we may be able to realize our desire to travel to space or even immigrate to space.

Mars not only has water, but also oxygen, because the rover Curiosity contains manganese oxide in the rock layer of Mars, indicating that there was a relatively concentrated oxygen in the past, and there is a large amount of rust in the dust of Mars, which is generally formed by the oxidation reaction of iron and oxygen.

Because there are traces of rivers on the surface of Mars, scientists found that there is still frozen water at the site of Mars, and there is still a lot of rusty iron on Mars, and only the presence of air can make iron rust, so it is judged that Mars may still have oxygen.

I think it's very likely that this is based on the analysis of the atmospheric composition on Mars, and as long as a probe can descend on the surface of Mars, the gas composition of the Martian surface can be analyzed.

There is oxygen and water on Mars. The atmosphere of Mars is mainly composed of leftover carbon dioxide (plus nitrogen (argon) and trace amounts of oxygen (and water vapor).

The average atmospheric pressure on the surface of Mars is only about 7 millibars (less than 1% of Earth's), but it varies with altitude and can reach as high as 9 millibars in the deepest part of the basin and only 1 millibar at the top of the Olympus Mountains.

But it's also strong enough to support the occasional hurricane and storm that sweeps across the planet throughout the month. The thin layers of Mars' atmosphere, while also creating the greenhouse effect, only raise the temperature of its surface5 much less than those of Venus and Earth.

The poles of Mars are permanently covered with solid carbon dioxide (dry ice). The structure of this ice cover is cascading, which is made up of layers of ice and changing layers of carbon dioxide in turn. In the northern summer, carbon dioxide is completely sublimated, leaving behind a layer of icy water.

This change in the cover of the poles due to seasonal changes has changed the pressure of Mars by about 25%. (Measured by the Corsair). However, observations through the Hubble telescope showed that the environment at the time of the Corsair's survey was not typical.

The atmosphere of Mars appears to be colder and drier than that surveyed by Viking.

Water and oxygen exist on Mars, but the content is very small, oxygen is only occupied, and the temperature difference between day and night is high, it is difficult for human beings to survive, at least until the environment is relatively suitable, the establishment of a space station and living base, and then enough spacecraft resources can allow humans to land on Mars on a large scale.

Although it has been established that there is water and even oxygen on Mars, there are still many steps to get to Mars. High-thrust rockets, how to survive in space for a long time, etc., are huge problems.

There are still three steps left, the first step is to invent Noah's Ark, the second step is to board Noah's Ark, and the third step is to land everyone on Mars.

Probably in 30 years, we can play on Mars, probably sometime in May 2015, Musk said that the second-generation Dragon spacecraft has the ability to transport scientific payloads anywhere in the solar system, whether it is a liquid surface or a solid surface or an atmosphere, and he added that the Dragon spacecraft, combined with the Falcon Heavy launch vehicle, can launch 2 to 4 tons of scientific equipment into the rocket. Currently, the largest probe to land on Mars is NASA's Curiosity Mars, which has a mass of about 1 ton.

SpaceX's Falcon Heavy launch vehicle is the largest rocket in human history, therefore, humanity has solved the problem of survival on Mars, they have to work hard to study Mars, all of which are waiting for a revolution in space navigation, both in terms of speed and load, which was unthinkable in the past, so when humans land on Mars in the future, most of the air problems will rely on chemistry to produce oxygen, and the benefits of local materials can be adopted.

Since the problem of air and water has been solved, then it is a problem of efficiency, according to the fastest scientific and technological speed of spacecraft at present, and according to the theoretical thought, Mars, its closest distance is about 55 million kilometers, it will take 6 10 months, and the financial and material resources consumed by one flight, even if the economic strength is stronger than the United States, it cannot sail many times in a short time.

Recently, Elon Marks of the United States was the first person to land on Mars now, claiming that he could reach Mars in the shortest 3 months in the next 50 years, and that we could build a base directly on Mars, so when humans land on Mars in the future, most of the air problems will rely on chemistry to produce oxygen, and the benefits of local materials can be adopted. Now that the problem of air and water has been solved, it is a matter of efficiency, according to the fastest technological speed of spacecraft at the moment.

As for the fact that it has been determined that there is water on Mars, and even oxygen is still a few steps away from landing on Mars, this is explained today.

If human beings do not plan to build Mars into a habitable planet, or are not sure of building a landing base on Mars, then human landing on Mars will never be realized, not only because of the distance between the Earth and Mars, but also because of the force of the cosmic stars themselves.

Many people may think that the current human beings have already landed on the moon, and it is believed that it is not far from landing on Mars, especially in recent times, a space agency has announced the discovery of water sources on Mars, and it seems that it is getting closer and closer to landing on Mars. But in fact, the situation of Mars and the moon is completely different, being able to land on the moon does not mean that you can land on Mars, with the current level of science and technology, whether you can invent a manned rocket to reach Mars is still unknown, and the most important thing is that humans cannot return to Mars at all.

The distance between the Earth and the Moon is about 400,000 kilometers, and the closest distance between the Earth and Jupiter is about 60 million kilometers, which is equivalent to 150 times the distance between the Earth and the Moon. Of course, this problem may be solved over time.

The most difficult problem for humans to land on Mars is how to return, although water and oxygen have been found on Mars, but the state of existence is completely different from that of Earth, and it is impossible for humans to use it directly after landing on Mars, and it is necessary to conduct repeated research and base construction on Mars before it is possible to finally land. However, the current probes will not return, and it is impossible for human beings to transport a large-scale survival base to Mars out of thin air, and it is in vain to land on Mars rashly, and it is in vain to have no living environment, and it is impossible to study Mars in detail at all.

The reason why you can't return after landing on Mars is because of the attraction of Mars, we all know that the earth has gravity, in fact, all the stars in the universe have gravity, the difference is only size. The reason why it can land on the moon and return is because the moon itself is a satellite of the earth, and the gravitational force is negligible affected by the earth, and only a small thrust is needed to return to the earth, but the gravitational force of Mars is not affected by the earth.

No, because Mars is not inhabitable, the content of carbon dioxide is greater than the content of oxygen, and the temperature is relatively high, making it unsuitable for human habitation.

It may be possible to survive on Mars in the future, but current scientific investigations show that we do not yet have the conditions to survive on Mars.

No, we also have to study some of the help of Mars, because we humans need to survive on Mars, and we definitely need a place to live, so it doesn't mean that we can survive.

Of course not, although the conditions on Mars are very abundant now, there are still greater challenges for human beings to complete before they can think of life on Mars.

Not. The environment on Mars is not suitable for human survival, but I believe that with the continuous efforts of Chinese scientists, our habitable Mars will become a reality.

No, these things are all brought up by hand, and the actual situation on Mars has not been investigated clearly, and it is not yet possible to survive on it.

Probably yes. Now scientists are still exploring that planet, and there are some factors that we can still survive, and maybe in the future.

This is a post with a low-level question, not worth refuting, and a post that grabs people's eyes.

There is oxygen on Mars, but in smaller amounts. Mars also has an atmosphere, which is somewhat similar to Earth, but carbon dioxide occupies a major position in the Martian atmosphere, and the others are nitrogen, argon, etc., as well as oxygen and water vapor.

Carbon dioxide is the largest component in the Martian atmosphere, and when the temperature on Mars is very low in winter, 25% of the carbon dioxide in the air will form dry ice, which will re-sublimate into the atmosphere in summer. This also makes the air pressure in the polar region of Mars vary greatly.

Fire surface morphology of Mars

Mars, like Earth, has a variety of terrains, with high mountains, plains, and canyons, and Mars is basically a desert planet with sand dunes and gravel all over the surface. Due to factors such as less gravity, the terrain size is also different compared to the Earth.

The topography of the northern and southern hemispheres is striking: the north is a lowland filled with lava, and the south is an ancient highland full of craters, separated by a clear slope; Volcanic terrain is interspersed with canyons, the North and South Poles are covered with dry ice (solid carbon dioxide) and water ice, and wind-formed sand dunes spread across the planet.
