Space weather

The atmosphere of Mars is mainly carbon dioxide, which is often attacked by strong sandstorms, and its temperature is often low enough to freeze blood. There are few sunny, windy and sunny scenes on Mars, and it is often attacked by sandstorms, which may even spiral up to several thousand meters. Bad weather conditions will endanger the landing of spacecraft on the surface of Mars, so it is particularly important to know the weather conditions on Mars in advance for completing the Mars exploration mission. To this end, the scientists of this bureau invented this Mars weather forecast system with the help of the principle of atmospheric circulation and the weather forecast system on the earth. The water in the earth's atmosphere is the most important factor leading to the change of the earth's weather, and the dust in the Martian atmosphere plays the most critical role in controlling the Martian weather. In addition, because the Martian atmosphere is thin, there is no water body like the earth's ocean to store heat, and the temperature change on Mars is more likely to go to extremes. At the same time, the rising of hot air and the sinking of cold air on the earth will produce wind, and there is a similar situation on Mars, but it will eventually show up as dust movement on Mars.

Mars is considered to be the most similar planet to the earth. Like the earth, the four seasons on Mars are also obvious. The day and night time is 24 hours, 37 minutes and 22.6 seconds, and the revolution time is slightly longer than the earth. A Mars year is almost two years on earth. However, many Mars researchers believe that Mars once experienced a prosperous period like the earth, but later it became desolate because of environmental changes.

On Mars, 95% of the gas is carbon dioxide. Carbon dioxide warms the earth, but it doesn't warm Mars. Because the atmosphere on Mars is thin, the density is less than 1% of the earth's atmosphere, and there is no way to preserve the heat, so the surface temperature of Mars is very low, rarely exceeding 0 degrees Celsius; In winter, the surface temperature of Mars will even reach-140 degrees Celsius. ?

At the poles of Mars, even carbon dioxide will turn into ice at such a low temperature. Dry ice forms thick ice sheets at the poles of Mars, just like icebergs at the north and south poles of the earth. These natural conditions constitute the unique climate environment on Mars. Compared with the earth, the conditions on Mars are poor but stable. Thin clouds and constant low temperature all the year round often make people feel that the weather on Mars is not particularly worthy of attention. But in fact, there are times when the situation on Mars suddenly changes. Zhan York said that there are huge sandstorms on Mars. These sandstorms will erupt every 2-4 years. When they erupt, dust rises from the surface of Mars, covering the whole of Mars in an instant, and then it will not disperse for months.

So there is no way for human beings to survive on Mars.
