It's too bad that America has spent a lot of money on Mars in recent years. What is there to explore on Mars?

Mars is a planet that we humans have been exploring all the time, and it has never stopped since humans began to explore the solar system. At present, it is known that Mars is an atmosphere dominated by carbon dioxide, but it is thin and cold, and dust is suspended in it. Mars has four seasons, but sandstorms happen every year. The temperature ranges from nearly 27 degrees in summer to minus 133 degrees in winter, and the average surface temperature is around minus 60 degrees, which is similar to the polar regions of the earth.

Of course, 60 degrees below zero is not a suitable temperature for human survival, but it is much better than other planets in the solar system. For example, the temperature of Venus is close to 500 degrees, and the air pressure is dozens of times that of the earth, not to mention people, and the detector will not take a few days. This is still a livable planet, not to mention other uninhabitable planets, either hot or cold. As for other conditions for human survival on Mars, it is still possible to solve them with sufficient energy.

Low temperature is the best solution, just use energy to warm it; Water or ice has been found on Mars, so it is unrealistic to feed a large population, and small-scale colonies or research facilities are still enough; As long as there is energy, oxygen can be produced locally. The main reason why Mars is red is that its surface is full of iron oxide, from which oxygen can be extracted. Therefore, it is precisely because of the possibility of colonizing Mars that the United States began to explore Mars on a large scale to prepare for future Martian immigrants.

As long as there is a suitable manned spacecraft, you can land on Mars for investigation. Once humans can establish a base on Mars and develop Mars, they can explore Titan and other celestial bodies more carefully through Mars:

About 4 billion years ago, the climate of Mars and the earth was very similar, with rivers, lakes and even oceans, but now Mars has become like this. Understanding the reasons is of great significance to protect the earth.

There is also an ozone hole on Mars. Studying Mars is helpful to understand the impact of the disappearance of the ozone hole on the earth.

If biological fossils can be found on Mars, it means that life will be born on the planet where conditions permit in the universe.

In the long run, Mars will be the new home of future mankind.

More importantly, Mars is relatively closest to the Earth. With the current space strength of mankind, it will take six months at the earliest to reach Mars, not to mention Saturn or even Jupiter, which will take several years at the earliest. All these factors have led the United States to greatly increase its exploration of Mars in recent years. In addition, as early as the 1970s, people began to explore Mars, but in recent years, the exploration of Mars has entered a critical stage. According to the latest news, the United States plans to send astronauts to Mars within 25 years. As a world superpower and space power, there is no reason why the United States should not be at the forefront of the world and take a big step in human exploration of Mars. The United States is duty-bound

From a political point of view, countries actually have very urgent hopes for landing on Mars. The last time humans went crazy on the moon, it was because of the cold war between the United States and the Soviet Union. These two countries proved their strength by landing on the moon. Now, in fact, China also has plans to land on Mars in 2030. Recently, the United States announced that it would return to the moon within five years, which was actually stimulated by China.

So in the final analysis, manned space technology is like a military competition to some extent. It aims to achieve a political goal and prove who is the biggest power in the world today.
