Is Mars a death star after all? How Mars died

Be. At present, all scientific research clearly shows that Mars is a "dead" planet, that there is no life on Mars, and that it is not suitable for humans to live on it.

The surface of Mars is shrouded in a thin atmosphere, desolate, dry, cold, and devoid of life. If Mars is like this all along, there is no such thing as "death".

It depends on whether there is life on Mars. Based on current space exploration and Mars exploration, no life has been found on it, so it can be considered a death star.

Of course, traces of liquid water have been found on Mars in ancient times, so it is not ruled out that there may be microorganisms somewhere on Mars. But this is only an assumption, and we still have to judge it based on the facts of the test.

Mars is a "dead" planet, there is no life on Mars, and it is not suitable for humans to live on it directly.

Mars can be observed with the naked eye. Observing planets and stars in the night sky, the slight difference is that the planets do not flash. If you continue to observe for many days, you will find that the position of the stars is relatively unchanged, but the positions of the planets are constantly changing.

Five planets. Mars:

Mars is the solar system.

Eight planets. One of them, the astronomical symbol, is the fourth planet in the solar system from the inside to the outside, belonging to the terrestrial planet, the diameter is about half of the earth, the axis of rotation inclination, the rotation period are similar to the earth, and the revolution is about twice the time of the earth's revolution. In the West, it is called "Mars", and in China, it is called "Yingfu".

The orange-red color is due to the hematite (iron oxide) on the surface. Mars is basically a desert planet, with sand dunes and gravel on the surface, and no stable liquid water body. The atmosphere, dominated by carbon dioxide, is thin and cold, with sand and dust suspended in it, and dust storms occur frequently every year.

Both poles of Mars have a polar cap of water ice and dry ice, which waxes and wanes with the seasons. Mars has two natural satellites: Phobos and Deimos, which are irregularly shaped and may have been captured asteroids.

On Earth, Mars is visible to the naked eye and can reach brightness, only larger than Venus and the Moon.

and the Sun is dim, but brighter than Jupiter most of the time.

People who love to show off, at the beginning, the saying was "people who will die if they don't show off", which means that people who don't show off will die on a planet. This statement is based on the old sayings such as "Mars" and "Mercury".

People who like to show off start by saying "the one who doesn't show up dies", which means that the one who doesn't show up dies on the same planet. This proverb is based on the old saying "Mars" and "Mercury".

The heroine of "Dead on Mars" doesn't seem to have succeeded in coming to Mars.

Wheat Dong. After losing contact with the Earth, he is awakened from hibernation by the System and, in disbelief, learns that the Earth is gone. So she began to try to contact the earth and human units, and in the end she only contacted the Mars base and met the male protagonist and the old cat.

Suddenly, one day, the old cat found a comet.

is gradually approaching the orbit of Mars by the group, threatening the safety of everyone's life. The three of them will be on the space station.

Transformation, preparing to let the entire space station fall into the Martian atmosphere, use the modified engine to slow down, and when it reaches an altitude of tens of meters, eject the spacecraft control room where Mai Dong is located, and then rescue it by two people on the ground. Because according to calculations, if the comet impact point is more than 2500 km away from the base, the base can be preserved. But in the end it was calculated that the closest point of the comet's landing was about 700 km, and the apogee was 1200 km.

In the end, the space station crashed, and Mai Dong failed to make a fuss on Mars or fall on the dates.

Mars is Earth's closest neighbor. It shares many of the same characteristics as the earth. They all have moons, they all have moving sand dunes, wind-blown dust storms, and they all have white ice caps at the north and south poles, except that the Martian ice caps are made up of dry ice.

Mars rotates once every 24 hours and 37 minutes, and its axis of rotation is inclination of 25 degrees, which is not much different from Earth. The surface of Mars is a desolate world, with 95% carbon dioxide in the air. Probe data obtained from the surface of Mars prove that in ancient times, there was liquid water on Mars, and the volume was particularly large.

This water converges on the surface of Mars into large lakes and even oceans. The many criss-crossing riverbeds we can see on the surface of Mars today may have been washed by currents at that time. In addition, the many teardrop-shaped "islands" on the surface of Mars are hinting at this.

In ancient times, Mars and the Earth were very similar, but the volume and mass of Mars were too small, with a diameter of 6,794 kilometers, about half of the Earth, and the average density was smaller than that of the Earth, so that its mass was only kilograms, while the Earth was 6 10 24 kilograms, and the mass of Mars was only 1 10 of the Earth, such a small mass made it impossible to retain the atmosphere, and the density of the atmosphere was less than 1% of the Earth's atmosphere. The process of Mars' death may be as follows: under the illumination of the sun, water on Mars evaporates into the atmosphere, ultraviolet rays cause water to decompose (on Earth due to the protection of the ozone layer, water does not decompose), hydrogen escapes into space, oxygen is heavier and slower to escape, allowing iron to oxidize, giving Mars a dazzling red color.

And because Mars' gravity is too weak and the atmosphere is too thin, the small amount of ozone formed cannot prevent the invasion of ultraviolet rays and protect the water from decomposition. Until one day, the water on Mars is gone (except for a small amount of water ice in the cold polar crown), hydrogen runs out, the proportion of oxygen in the atmosphere is only 0.13%, and the stable carbon dioxide becomes the main component of the atmosphere, but the thin carbon dioxide does not play the role of the "greenhouse effect", and Mars becomes cold and biting, raging with sand, and becomes a dead planet.

The Sun is a yellow dwarf, and the lifespan of a yellow dwarf is roughly 10 billion years, and the Sun is currently about 5 billion years old. As the sun ages, its luminosity increases steadily. In about 5 billion years, the Sun's interior will be almost completely depleted of hydrogen, and the Sun's core will collapse, causing the temperature to rise, a process that will continue until the Sun begins to fuse helium into carbon.

Since helium combustion produces more energy than hydrogen combustion, the outer layers of the Sun will expand and release a portion of the outer atmosphere into space. When the process of switching to new fuels ends, the mass of the Sun will decrease slightly, and the outer layers will extend to the current orbit of the Earth or Mars (in which case the two planets will be farther away from the Sun due to the decrease in the mass of the Sun). Since the growth of the sun's energy is not commensurate with the increase in radius, the temperature on the surface of the Sun will be lower than it is now, turning into a red giant.

After billions of years from this red giant, the helium fuel will also be depleted. As if hydrogen fuel was consumed for the first time, the core of the sun shrinks again and the internal temperature rises. For very large stars, this collapse leads to the fusion of carbon.

However, since the Sun is not massive enough to produce carbon fusion, it will become a white dwarf; As the internal temperature and luminosity decrease, it eventually becomes a black dwarf that does not emit light. When the sun dies, Mars and the Earth, as well as other planets, will naturally die.

I once watched a documentary, saying that it was because of a solar storm that erupted on Mars, because this solar storm was too strong, destroyed the magnetic field of Mars, and the atmosphere that guided Mars disappeared, without the protection of the atmosphere, and the temperature rose, so it became the current lifeless Mars, but whether there is life on Mars at present still needs further research from scientists.

The distance between the sun is long, the size is small, and the mass is small. Poor heat preservation . The geological movement gradually disappears, and then the magnetic field disappears, and it is deserted.

Don't worry, of course not, it's just that Mars only lost seven lives.

The first died under the claws of the long whip;

second, lost in green cough;

The third article was taken away by Huang Mao, the deputy patriarch of the Shadow Clan, in the war of the four clans in the fourth part;

Fifth, Eagle Frost ambushed, and it was Blackberry Palm who saved him;

Sixth, invasion of house mice;

Seventh, the four clans were bitten to death by Huang Mao in the scuffle.

I know so much at the moment, Mars will never die so soon! Besides, he has two lives left! However, according to the author and netizens, Mars will die in the fifth part, and he will die with Charcoal Heart (the child of Charcoal Fur in the afterlife, Berry Nose and Honey Fern's sister, born at the end of the fifth book of the second part, and Charcoal Fur died to protect them in the attack of the badger, and later became Charcoal Heart in the afterlife).

Hope this helps! (^

I only remember writing in the last book of the tetralogy that Mars was burned to death by burning branches.

It is very small, but there is a volcanic eruption, and it has very little internal energy, and the internal energy is quickly exhausted, and it gradually becomes a death star.

Die as much as you want

An object does not change its state of motion at will, unless an external force is applied to it, and it does not change as soon as it is exerted.

If you have learned the knowledge of junior high school physics, you will know that the force applied to the object will cause acceleration, and the object itself has inertia, and the greater the mass of the object, the greater the inertia.

So, how much force does it take for a behemoth like Mars to change its motion and hit the Earth? If this force does not occur in a vacuum, there is no reason to think that Mars will come and hit the Earth.
