On July 23, China’s Mars probe? Tianwen-1? was launched from the Wenchang Satellite Launch Base in Hainan by the Long March 5 Ya4 rocket. This is China’s first Mars exploration mission. The goal is to achieve Mars orbit, landing and patrol detection through a single launch mission, which is extremely difficult. The successful launch of Tianwen-1 is of great significance to mankind. ?Tianwen-1? Mars exploration mission.
The China National Space Administration announced the name and logo of the planetary exploration mission Tianwen at the launch ceremony of China Space Day on April 24. The first Mars exploration mission was named Tianwen. No. 1?, and subsequent planetary missions will also be numbered sequentially.
So some people can’t help but ask: Why did you choose this name? What is its profound meaning? ?Actually, anyone who knows about my country's space exploration missions knows that my country's lunar exploration project was officially launched in 2004 and was named "Chang'e Project".
This is named after the ancient Chinese mythological figure Chang'e, and Chang'e's flight to the moon is an ancient myth spread among Chinese people. In addition, our country will also launch China's first lunar rover in the lunar exploration project. Named "Yutu", these all express people's beautiful meaning for the moon.
This Mars exploration mission? Tianwen? is taken from the poems of the poet Qu Yuan during the Warring States Period. In the poems, Qu Yuan raised a series of questions about the sky, expressing his exploratory spirit of pursuing the truth. This name shows the importance our country attaches to Mars exploration.
Secondly, the "Tianwen-1" mission is the first practical launch of my country's Long March 5 series of launch vehicles. The Long March series of launch vehicles have undertaken 96% of my country's launch missions, and the Long March 5 was developed by my country. It is a new-generation launch vehicle with the largest take-off mass, the thickest core stage diameter, and the strongest carrying capacity. With this "Fat Five" here, this Mars exploration mission will be successfully completed and live up to expectations!
Finally, the successful launch of the "Tianwen-1" mission means that my country's independent exploration of planets has taken a further step.
Mars is the fourth planet closest to the sun, and Mars and the Earth have many similarities, such as mountains, canyons, plains and other terrains, rotation cycles, day and night time, seasonal changes, etc. The value of scientific research is very high, which is why Mars has become a popular travel destination for planetary exploration by various countries.
Affected by the movement of celestial bodies, there is only a Mars launch window approximately every 26 months. This period is called "Mars Opposition", which is the approximate time between Mars, the Earth and the Sun. When in a straight line.
The mission goal of China’s Mars exploration mission, Tianwen-1, is to achieve Mars orbit, landing and patrol detection through a single launch, that is, to complete the orbit in one go in the first attempt. The mission is to carry out global and comprehensive exploration of Mars and carry out detailed patrols and surveys of key areas on the surface of Mars.
This is the first time in the history of human Mars exploration. From this, you can imagine how difficult and risky this mission is to implement! In this seven-month process, every step has a mission. This is destined to be an extraordinary journey to Mars that carries China’s dream of planetary exploration. If this mission is successfully completed, China’s Mars exploration will surely will be recorded in the annals of human history. Why is this mission so difficult?
We might as well look at the process of various countries’ exploration of Mars to find out. According to statistics, from 1960 to the present, the five countries in the world that carry out planetary exploration have all launched Mars probes, a total of more than 40 times.
Since 1992, various countries have launched 19 Mars probes. Mars probes have been launched in almost every detection window. There are still 8 Mars probes in orbit or on the surface of Mars. However, along the way, nearly half of the Mars exploration missions ended in failure, which scientists call the "Mars Curse".
The reasons for failure include battery exhaustion, failure to turn on the solar panel, excessive landing speed, etc., but the fundamental reason is restricted by technical conditions. So far, eight probes have successfully landed on Mars: Viking 1, Viking 2, Pathfinder, Opportunity, Spirit, Phoenix, Curiosity, and InSight, all developed by the United States. Every time the Mars launch window comes, multiple countries will participate in the launch of Mars probes, and this also creates the phenomenon of "Mars heat".
The successful launch of the Tianwen-1 mission is expected to deepen mankind's understanding of Mars and facilitate the search for a second habitable planet for mankind. The launch of Tianwen-1 successfully kicked off my country's planetary exploration. In previous Mars explorations, humans found evidence of the existence of water on Mars. This also made humans think about whether Mars will become the second habitable planet for humans in the future. .
The great modern physicist Hawking said in an interview in 2010: The earth's environment may change within 200 years, and if humans do not take action at that time, they may be destroyed together with the earth.
So he said that humans must leave the earth in the near future, and the successful launch of "Tianwen-1" will definitely deepen humans' understanding of Mars and will also help explore the reality of the concept of human immigration to outer space. significance.
In short, the launch of "Tianwen-1" not only has extraordinary symbolic significance for our country's planetary exploration, but also will bring mankind's understanding of Mars to a higher level.
