Ive never been so proud. On July 23, an astronomy enthusiast from Guangzhou sighed at the beach near Chinas Wenchang space launch site.

Before 8:00 in the morning, he set out from Wenchang with his children and father, and drove for nearly an hour to this beach in Longlou Town, which is known as a rocket launching resort by local people. In the fierce sunshine of Hainan, he and thousands of tourists from all over the country looked forward to the spectacular launch of tianwen-1.

The crowd is looking forward to it.

Some people have been stationed on the beach for nearly three hours in order to occupy the favorable terrain; some people have swam into the sea, lying on the big rocks and holding up their selfie poles; whats more, the whole family mobilized two people on the beach and two people looking for high slopes

Around 12:40, people began to count down ten! Nine Three! Two! One!

With a huge roar, the Long March 5 was launched from Chinas Wenchang space launch site, and the crowd cheered. How beautiful What a spectacle With the magnificent wake clouds across the sky, some people began to clap their hands excitedly, one by one, and the whole beach was filled with applause.

At 12:41 on July 23, Chinas Wenchang space launch site, the Long March 5 remote 4 launch vehicle launched the first Mars exploration mission, tianwen-1 probe. After about 2167 seconds of flight, the probe was successfully put into the scheduled orbit, which started the Mars exploration journey, taking the first step of planetary exploration in China.

1u3001 At the moment of launch, I couldnt help crying

This is a start that is expected by all.

As Chinas first autonomous Mars exploration mission, tianwen-1 is undoubtedly a heavy attack in Chinas space history.

In Wenchang, this sense of expectation is even greater. Because of the location of Wenchang space launch site, the attention of the outside world is constantly gathered here, and various resources are constantly converging here. This seaside town stands at the center of the worlds focus in various senses, and its every move attracts much attention.

When there is no epidemic, hundreds of thousands of tourists may come in at this time of year to watch the rocket launch. The owner of an octopus ball shop near Wenchang beach told us that his business depended on these months every year. This year, he was less affected by the epidemic, but the shop was already overcrowded.

This rocket economy has affected every aspect of Wenchang.

The local hotel can see the one-day tour leaflet of the rocket base. If you go out and inquire about it, you will meet the driver who provides services to Longlou town. You can see the style of rockets in hotels, parks and even desserts.

It is for this reason that the National Astronomical enthusiasts are attracted.

Specially brought the child to see the rocket, wants him to worship the science to walk the right path. A father from Jiangsu Province told reporters. And his son used excited heart, shaking me to describe the mood at this moment.

I cant help crying. Ive never been so proud, the teenager, who was still in junior high school, said after the launch

A 70 year old man from Haikou said, I wish our countrys aerospace industry a vigorous development.

2u3001 If all goes well, Chinas deep space exploration will take a big step forward

Many people call Mars the graveyard of explorers..

So far, mankind has carried out 44 Mars exploration missions, including 57 missions. Among them, 19 missions have been successful and 25 have failed, with a success rate of only 43%. The success rate of the mission was lower than 53%.

In 1962, after the launch of Mars 1, the Soviet Union launched seven Mars probes in 11 years. All of them failed, lost contact and crashed. None of them achieved complete success. On November 8, 2011, Russia launched its first Mars probe since the collapse of the Soviet Union. However, due to the failure of the probe, together with Chinas Yinghuo 1 satellite, it crashed off orbit.

Liu Boyang, Ph.D. of the National Astronomical Observatory of the Chinese Academy of Sciences and a columnist on astronomy and eight trigrams, told reporters that many of the Mars landers in history had malfunctions during the landing process, leading to mission failures.

There are two reasons behind it

One is that Mars is still a little far from earth. He explained that even when Mars was closest to earth, it would take more than three minutes for a signal to travel from Mars to earth at the speed of light, and a round-trip communication would take six minutes. Because of this time delay, we can not receive the information from the detector in time and then send out instructions. We can only rely on the detectors independent judgment and control, which requires a high IQ of the detector itself.

Second, Mars has a thin atmosphere, and its atmosphere is less than one percent as dense as earth. This makes it difficult for it to provide enough air resistance to slow down the speed of the lander; but at the same time, its density is enough to make the detector reach a high temperature due to friction when entering the atmosphere. If the protection is not in place, it will still pose a certain threat to the detector.

China for the first time! How did the most difficult Mars exploration in human history be completed? (source: reverse thinking)

Ding Ze (pseudonym), an astronomy enthusiast engaged in physics research, told reporters, flying to Mars also means leaving the earths near earth orbit, and the spacecraft will lose the protection of the earths magnetic field. Cosmic rays and high-energy particles of the sun will test electronic equipment even more.

If it is successfully implemented, it will make Chinas deep space exploration a big step forward. Liu Boyang wants to complete the three-day round of Mars mission, which is extremely difficult.

In fact, there were originally four Mars exploration missions planned to be launched in July this year, including tianwen-1 of China, Mars 2020 of the United States, hope Mars probe of UAE, and ExoMars 2020 mission of ESA and Russian space agency. However, due to the impact of the epidemic, the task of Russian European cooperation has been postponed to 2022, with only three tasks left: China, the United States and the United Arab Emirates.

Liu Boyang also told reporters that the UAE probe is just a Mars Orbiter, which only contains a man-made satellite orbiting Mars. The main mission of the United States is to bring a Mars rover, and it will also carry a small helicopter. Chinas mission is to have both orbiters and Mars rovers, which are relatively the most complex and challenging.

As Chinas first Mars exploration mission, such a design can be said to reflect our astronauts strong confidence in our space engineering technology. We hope that tianwen-1 will go well and complete its scheduled mission successfully

3u3001 If you dare to ask the sky, you are brave enough!

In the eyes of local villagers in Longlou Town, the Chinese space workers in Wenchang launch base are familiar with and unfamiliar with.

In this Hainan town with a total population of 26000, these spacemen who come and go in uniform have long been integrated into the daily life of local people and become one of the features of the town itself.

Every time there is a deafening roar of rockets above the Dragon Tower, this group of ordinary people represent the Chinese people to climb the worlds scientific and technological summit, and focus the worlds attention on it. The local people will always be proud.

A local driver said with pride, they are winning glory for the country. Amazing!

Through thousands of difficulties into great cause, everything in the world is hard.

A way to ask the sky requires the painstaking contribution of generations of astronauts.

Ding Ze told reporters that the first thing to bear the brunt is the accumulation of experience, technology and talents of the Change project. From 2007 to 2018, the Change project has gradually realized the orbit, landing and inspection of the moon through four missions, which have accumulated practical experience and technical summary.

Moreover, in the past decade, the Long March 5 launch vehicle fat five was in place. This time, the fat five was also launched again. China can use its own carrier rocket to carry out the earth fire transfer orbit launch mission.

In addition, the whole process of Mars probe landing on the surface of Mars involves more engineering design problems.

For example, the high temperature in the process of entering the Martian atmosphere requires further deceleration after entering the atmosphere, which involves the design and manufacture of supersonic deceleration parachutes, and finally, the use of airbags and thrust rockets can finally land safely on the surface of Mars. Whats more difficult is that all these need the detector to complete independently, and the detector itself should be intelligent enough.

It is brave enough for us to dare to ask the sky and step into the fields that our predecessors have not set foot in. Ding Ze sighed.
