There are seven rovers in three countries on Mars. Can they meet? Has the colonial war on Mars started?

On May 15, Beijing time, China Tianwen-1 successfully landed the "Zhu Rong" rover on the surface of Mars, and then on May 19, Zhu Rong sent back the first photo of Mars. People can see the five-star red flag rising on the moon through photos, which indicates that China's space industry has made great progress, and China has become the third country to successfully land on Mars for exploration. In the next 90 days,

China is the third country to successfully land on Mars and explore it. Who are the first two? I think everyone can guess that it is Russia and the United States. And this rover in China is already the seventh one on Mars. Whose are the first six?

In fact, it was the Soviet Union that launched a probe car for the first time to explore Mars. 197 1 year, the Soviet Union launched Mars 2 and Mars 3 probes to Mars continuously. Unfortunately, Mars 2 crashed during the landing, but Mars 3 landed successfully. Unfortunately, Mars 3 was hit by a sandstorm.

Since then, the exploration of Mars has been almost monopolized by the United States. 1977, the American "sojourner" flew to Mars, worked on the surface of Mars for three months, and returned 550 photos, which was also the first-hand information about the environment of Mars.

Then in 2004, the United States sent Spirit and Opportunity to Mars. Spirit lost contact after six years of work, and Opportunity also suffered a sandstorm in 20 15, and lost contact from then on.

In addition, the United States sent Curiosity to Mars in 20 12 and launched Perseverance in 2020. These two rovers are still working.

Next is China's "Zhu Rong". As a result, humans launched a total of eight rovers to the moon, of which 1 crashed, seven successfully landed, and only three of the seven can work normally at present. There are two in the United States, China 1, so can these working rovers meet?

As shown in the above figure, the current relative positions of the three rovers are as follows: the coordinates of Perseverance are 18.44 N 77.45 E, and the coordinates of Zhu Rong are 25.1n109.9e. According to the coordinates and the radius of Mars, the relative distance between them can be calculated as/kl.

The speed of Perseverance is about152m per hour, while the patrol speed of Zhu Rong is about 40m per hour, and the fastest speed is about 200m per hour. If they face each other at the fastest speed, it will take 2 15 days to meet, while the distance between Zhu Rong and Curiosity is longer and it will take longer. So this handshake on Mars may be difficult to achieve. If one day China's rover can shake hands with the American rover on Mars and cross the planet, it will be no less significant than Armstrong's "one small step for the individual and one giant step for mankind" on the moon.

With more and more rovers landing on Mars, people can't help thinking about a problem. Has the colonial war on Mars started? Columbus discovered the American continent, then the western countries established their own colonies in America, and finally established the United States. Will the descendants of these colonists who now make up the United States continue to do the same thing on the moon?

In fact, China, the United States, Russia and other countries signed an Outer Space Treaty as early as 1966, stipulating that in the process of space exploration, human beings will not make territorial claims to the space of other planets, and other celestial bodies in the sky are the common wealth of all mankind. All major countries should use outer space peacefully and avoid deploying nuclear weapons and weapons of mass destruction in the universe. This treaty is invalid.

On the surface, this treaty has agreed that space, including Mars, belongs to all mankind and countries are not allowed to privatize it. But what about the facts? Space belongs to all mankind, which means that all countries can develop and utilize it, but few countries can really explore and utilize Mars, and the current exploration is based on countries, not global cooperation. If the United States benefits from the moon, will it be distributed to other countries? Obviously impossible.

Furthermore, Mars is the planet that human beings are most likely to move into space at present. There are many similarities with the earth, including oxygen and water, and the distance from the earth is also relatively close. If one day the United States has the ability to send humans to the moon and establish permanent settlements on the moon, is it possible to open it to other countries? Obviously, it is a fantasy. And even if the United States still abides by the convention, the land belongs to all mankind, but the buildings on it belong to the United States. Isn't it actually a disguised land occupation? By the time other countries have the ability to land on Mars, the United States will have become the master of Mars. By then, the United States may also become the largest real estate agent on Mars, and may even become the strongest country on Mars again.

Although the purpose of China's landing on Mars is obviously pure scientific research and exploration, who knows if there will be a conspiracy in a certain Congress? So no matter from which angle, Zhu Rong's landing on Mars is of great significance. Mars is no longer the "exclusive" planet of the United States. With the existence of other countries, no matter what the United States wants to do, it can't be as unscrupulous as before. Perhaps, with the increasingly tense international situation on earth, the competition on Mars has quietly begun.
