People on the future interstellar route will remember how we “fly”

On the evening of December 27, the Long March V remote three carrier rocket was successfully launched. Only those who understand the twists and turns of the difficulties, can understand this simple express represents what weight. Long March 5 series of launch vehicles, is China’s need to meet the needs of further space development to develop a large-scale launch vehicle, also known as “Fat Five.”

Arrows to the sky

Long March 5 series of launch vehicles, is China’s need to meet the needs of further space development to develop a large-scale launch vehicle, also known as “Fat Five.” Its lumbar diameter (core stage) reached 5 meters, the series consists of the two-stage semi-form basic Long March 5 carrier rocket (CZ-5), the non-second-stage half-form Long March V B carrier rocket (CZ-5B) and the addition of the above-level Long March V/Expedition 2 carrier rocket (CZ-5/YZ-2), geosynchronous transfer orbit and low-Earth orbit carrying capacity will reach 14 tons, 25 tons, respectively.

Long March V heavy carrier rocket is the first heavy launch vehicle produced by China’s independent research and manufacture, bearing many of the space responsibilities that follow, and will play an extremely important role in the development of China’s space industry.

The Long March 5 began its research and development in 2006 and made its first successful flight at the Wenchang Space Launch Site in Hainan on November 3, 2016.

On July 2, 2017, the Long March 5 remote two carrier rocket was launched experimentally at the Wenchang Space Launch Site in Hainan, and the rocket malfunctioned when it flew to 346 seconds, causing the engine to lose thrust. That night, Xinhua news agency issued the news of the second launch of The Long Five.

The reputation of the Long March series of launch vehicles is derived from their extremely stable play, year after year, cheering, people have long been accustomed to the high success rate of Chinese spaceflight. However, in the face of a high success rate, we can not avoid the fact that space, has always been a high-risk cause, setbacks are always inevitable.

On December 27th, the Long March V asked the sky again. It is 908 days since the last launch defeat.

Over 908 days, the rocket test team conducted more than 40 key technical tests and 15,000 seconds. In 908 days, the Wenchang space launch site, which lifted off from the rocket, carried out more than 50 emergency drills, organized two practical exercises, upgraded the reliability of the launch site equipment facilities, and trained nearly 50% of the first-time mission personnel to be trained to become 100% of the excellent operators who passed the induction assessment.

And for the core of the rocket – large thrust hydrogen and oxygen engine, the rocket test team spent more than two years to complete the past nearly 7 years of work, the long march 5 more than two years of engine problems to thoroughly check, in order to make the engine accident no longer repeated, the Long March 5 stable sent.

These two years are also known as the “dark moment” of China’s spaceflight, although there are many outstanding achievements in the project, Beidou satellite navigation and so on, but the long march 5 launch failure, china’s major space mission to carry out the impact, many plans have to be postponed.

The successful launch of “Fat Five” is one of the best two kicks the astronauts have brought to the end of 2019, and a brilliant spark for a new super-space year.

But not only that, “Fat Five” rebirth, so that all concerned about its spirit of one, undefeated pride is noble, but after the failure of Nirvana dazzling extraordinary.

To be in the body

The Rocket family has an iron rule: being fat and thin determines the capacity to carry. In the Long March family, the Long March 2 series, the Long March 3 series, and the Long March 7, the core level (waist diameter) are all 3.35 meters, which is the largest size that the railway transport tunnel can pass through. This size greatly restricts the carrying capacity of our rocket.

Comparing large-capacity rockets abroad, the U.S. heavy-duty Falcon rocket is 64 tons, the U.S. Delta IV is 28 tons, the Russian Angara 24 tons, the Russian Proton rocket 23 tons, and the European Union’s Ariane V 21 tons.

As the space engineering program unfolds, the task ahead gets heavier and heavier – a literal weight, such as the Tiangong III space station, which consists of three 20-ton compartments, a core module and two experimental modules. This task, the Long March 2 F, the Long March III B, the Long March 7 can not be competent.

Known as the Chinese God Arrow, the Long March II F has a near-Earth orbit capacity of 8.8 tons. Long March III B-enhanced, near-Earth rail capacity of 12 tons. None of them, and missions such as a Mars rover and a return lunar probe, are no.

We must have the Long March 5. Not because we’re in front of any country, but because without a big-capacity heavy rocket, our sea of stars is impossible to talk about.

Now, the Long March 5 has finally won the battle for the turn, and it has become China’s most iconic mission for space flight in 2019. And this, not only because it determines the follow-up to the Mission, the manned space station and the first Mars exploration and other major engineering missions, but also because it is in a super-intuitive way, the scientific experiment from failure to success process, really presented to all.

The obstruction and long line will be to

The space industry to a country, means security and the future, without the space industry, there is no security, let alone the future. And the star sea is not a distant concept, now space has long been a place of great power, the development of space is not only a military need, but also an economic need.

According to a 2017 NASA Report, the world’s space economy totaled $383.5 billion that year.

The aerospace industry is also driving the emergence of new processes, new materials and new products in numerous fields. The Apollo moon landing program in the United States has supported 20,000 businesses, more than 200 universities, and more than 80 research institutions, with more than 300,000 scientists. The project has contributed to technological advances in a variety of areas in the United States, including liquid-fueled rockets, microwave radars, radio guidance, synthetic materials, computers, wireless communications, and more. The subsequent 4000 high-tech patents and technologies were converted into civilian use, driving the development of the entire technology, but also put the United States on the highest end of the industrial chain.

Boeing, GM, IBM, Hewlett-Packard, Microsoft, AT?amp;T, Qualcomm and other American giants as you know it are all beneficiaries of the Apollo moon landings. Improvements in integrated circuits and the birth of Silicon Valley are also closely related to the Apollo program. Modern solar panels, too, matured in the Apollo program, and now we can use solar energy successfully and effectively, which has to be said to be a great credit to NASA.

In the past 100 years, we have missed the Great Sea, missed two industrial revolutions, and caught the tail of the third industrial revolution.

The Chinese Academy of Sciences academician, the general director of various models of the Wei series, the chief designer consultant, 74-year-old scientist Ye Peijian once said:

“The universe is the ocean, the moon is the Diaoyu Island, Mars is Huangyan Island, we can now go to us not to go, later people to blame us.” Others go, others take over, you can’t go anymore. “

We can’t miss the sea of stars any more.

From then on, if you look back at the important moments of China’s space flight in 2019, remember Fat Five. When the words of the sea of stars come back to mind, you should thank the pioneers who bravely made their way into space, and the strong team that has been going through the defeats and the trials behind them.

If you start from this moment in your new interest in aerospace, now is a once-in-a-lifetime opportunity. “Moon and Beyond” space art exhibition with science, culture and art in one body – Guangzhou Station is currently being held at the Haixinsha Exhibition Hall in Tianhe District, Guangzhou, and will be on display continuously from December 20, 2019 to April 5, 2020, with an exhibition area of 3000 square meters to our country Focusing on lunar exploration and space achievements, focusing on the stars, human moon landings, Mars exploration and other topics, with 360-degree panoramic video, picture text explanation, physical and model exhibition, science lectures, concerts and other rich and diverse forms, to spread space knowledge to the public, share the great spirit of human courageous exploration.

Under the Guangzhou Tower, above the moon, see if this will become a place to ignite your dreams.
