Mars is not the closest celestial body to the earth. Why has human exploration of Mars never stopped?

A trip to the Star Empire has always been an ideal for people. In order to better realize this ideal, experts devote their life to the research and development of technical products. It is precisely because of their selfless dedication that today's aerospace engineering development has been achieved. Although the aerospace industry has not happened for nearly a hundred years, as we all know, it has made outstanding achievements during this period. From the moon to Mars, we have set foot on many planets, and we constantly launch various detectors to touch the earth and aliens.

Since the Soviet Union landed on Mars, it has been highly concerned all over the world. Nowadays, many countries have successfully launched probes to Mars and established relative navigation channels. Similarly, on May 1, China dispatched the "Zhou Tai" rover and its "Tianwen No.1" probe, which successfully reached Mars, becoming the third country in the world to land on Mars. In the past few months, Gong Sheng-1 took various photos of Mars and transmitted them to Earth, which enabled us to record our journey of exploring Mars together.

At this time, some people will ask, isn't there a Venus next door to the earth, not closer than Mars? Why haven't you heard about exploring Venus so far?

People failed to detect Venus. In the 1960s, before people explored Venus, they initially thought that Venus was more valuable than Mars. As can be seen from the measured data, Venus is rich in resources and is the closest planet to the Earth, so many countries are ready to land on Venus to find out.

1961February 12, the former Soviet Union launched the first "Venus-1" probe to Venus. Everything was normal during the transmission, until the detector suddenly lost its signal when it was 96,000 kilometers away from Venus.

It was not until1967,65438+10, 12 that the "Venus 4" detector was sent out again. After several failed launch experiences, it finally reached Venus in June of 18, and measured the data information of Venus temperature and standard pressure. In the next few weeks, Venus IV made preparations for landing ahead of schedule, but encountered obstacles in the landing process. After entering the earth's atmosphere, the plan was forced to land, and suddenly the communication was terminated.

For this safety accident, biologists believe that it is caused by the destruction of the wireless antenna in the landing module, or it may be caused by the high temperature and working pressure of Venus. After several failed explorations of Venus, countries all over the world also gave up the exploration of Venus. The natural environment here is extremely extreme, and the cost of input is not positively related to the acquisition.

The true face of Venus In everyone's traditional cognitive ability, Venus should be similar to Mars, because it also belongs to the Earth-like planet, but in fact, the force of Venus is very great. If people are going to Venus, they will have a rest. In addition, 96% of Venus's atmosphere is composed of carbon dioxide, its atmospheric pressure is 92 times that of the Earth, and the average surface temperature is 462℃, which requires more heat than Mercury, the nearest to the sun, so it is called the hottest planet in the solar system.

In addition to this climatic factor, there are various active volcanoes on Venus, and it is also the largest planet with the largest number of active volcanoes found at this stage. Because there are a large number of active volcanoes, this volcanic eruption will cause a lot of carbon dioxide and its sulfur. When this steam flies into the earth's atmosphere, it will combine closely to produce hydrochloric acid.

In the past few decades, many countries have tried the idea of Venus, and basically the same result. This kind of detector has long been destroyed or unstable before it falls down, unless it ends in failure. Even though this detector is made of all kinds of safe and protective raw materials, it still can't resist the corrosion of high temperature and a lot of sulfuric acid. People gradually lost their imagination of Venus, and even the idea of immigrants investing in Venus was completely solved.

Why explore Mars compared to Venus? The natural environment of Mars is much better. At least the detector can be integrated into the local natural environment, and it is not easy to lose contact due to external factors. This also greatly increased the cost of exploration, collected a large number of data and information on the surface of Mars, and laid a solid foundation for the later manned spacecraft landing.

During the years of exploring Mars, experts once suspected that there was liquid water on Mars, and even found rivers. As we all know, the representative of marine life, if water is really found on Mars, will there be other life on Mars? If liquid water is really found, it will be unthinkable for people to immigrate to Mars in the future.

Venus, full of mystery, is covered with a thick mask. It is covered by highly reflective and opaque hydrochloric acid clouds, and all the light from space is avoided by it. It is puzzling that Venus probably had a deep sea in the past. Tens of millions of years ago, it was probably due to uncontrollable global warming that the temperature rose, which led to the evaporation of water in the stars, and then it was converted into hydrogen and oxygen due to the electromagnetic field of the planet. Then the hydrogen was dispersed into space by the solar wind, and then disappeared.

Biologists have found phosphine in the atmosphere of Venus, which indicates that there is alien life on this star. In any case, the conditions of Venus are so extreme that it is difficult for people to find it in a short time. It is still a very mysterious existence.
