Mars immigrants CCTV news

Generally speaking, if water is below freezing point, it can still exist in liquid state. Such water is usually called "cold water". In fact, if the temperature of water is lower than the freezing point, the freezing point temperature corresponding to pressure can remain liquid, which is a common phenomenon. After all, whether water is liquid or solid is determined by the temperature and pressure in the region, which does not mean that water must be below freezing point to freeze. So this is the main reason why the water found on Mars can remain liquid even if the temperature is much lower than 0 degrees.

Is it a good thing to find a liquid water lake on Mars? Although no astronauts have landed on Mars in China, according to the relevant situation, there is still water on Mars, and many news reports have reported that a liquid water lake has been found under the ice near the South Pole of Mars. This water lake is about 20 kilometers wide and hidden under a huge polar glacier. In a word, water does exist on Mars, but most of it still exists in the form of ice.

As for why liquid water on Mars does not exist on the surface, but under the huge polar regions, it is mainly because the mass of Mars is only 10.7% of that of the earth, and most of the water on the surface has been lost into space, and most of this water exists in the form of water vapor. After the news was discovered, many people thought that it might not be a good thing to find liquid water on Mars. Whether there are signs of life on Mars is an unsolved mystery, but according to the current situation, there really will be no life on Mars, but whether there will be life in the future is still unknown.

Some people think that Mars has water, so is Mars suitable for human habitation? In fact, according to relevant data, although there is water on the surface of Mars, most of it is mainly diving, which is not suitable for human habitation at all, and the temperature and water activity on the surface of Mars are beyond our tolerance. Presumably, some people's desire to immigrate to Mars has vanished.
