China is in Jiuquan Satellite Launch Center.

Use the speedboat-1 A carrier rocket.

Successfully launched the first star of Galaxy Space.

This launch is the first appearance of the clipper series launch vehicle in 2020.

It is also the eighth launch mission of the Kuaizhou-1A carrier rocket.

The launch coincided with the Spring Festival.

The rocket arrow is painted with elements such as the word "Fu" and "Fu Qiang Fu" in the New Year.

It represents the wonderful Chinese New Year wishes of China astronauts to the motherland and people.

What is the first star of Galaxy Space?

↑ Poke the video to see how awesome the technology of the first star of Galaxy Aerospace is.

Galaxy space first star

It is independently developed by Galaxy Aerospace (Beijing) Technology Co., Ltd.

Low Earth Orbit Broadband Communication Satellite with International Advanced Level

Communication frequency bands such as Q/V and Ka are adopted.

Transparent forwarding communication capability with 10Gbps rate.

The height of running track is 1200 kilometers.

A single star can cover 300 thousand square kilometers

It is equivalent to the area of 50 Shanghai cities.

Start with this starting star

China has taken the first step in the journey of 5G "space communication"

The 5G era has kicked off

However, the coverage of the global network still faces great challenges.

It is difficult for ground base stations to cover desert, ocean and other areas.

Low orbit broadband communication satellite can solve the problem of global network coverage and access.

Scenes such as brushing short videos and making video calls on the plane.

Will become a future within reach.

The "online celebrity" rocket that was screened by the track cloud.

Kuaizhou-1A carrier rocket

It is the first launch vehicle in China’s fast boat series to be put on the market.

Specially tailored for 300 kg low orbit small satellites.

A small rocket for commercial launch.

Last year, it "exploded overnight"

On the evening of December 7, 2019

A dragon-shaped cloud appeared in the sky in Beijing.

A circle of friends "photo contest" quickly opened.

Netizens in Beijing, Tianjin, Hebei and other places have exposed "the same cloud"

Subsequently, @ Meteorology Beijing @ China Weather @ Aerospace Science and Technology "claimed":

"This is the track cloud left by the launch of the Kuaizhou-1A carrier rocket."

How fast is the "fast boat"?

↑ Poke the video to see how fast the "fast boat" is.

Whether it is the performance period or the launch time.

"Kuaizhou" is the fastest record holder among many launch vehicles in China.

In 2019, "Fast Boat" set a record for the shortest launch interval of the same type of rocket at the same launch site.

At 11: 40 on November 13, 2019

The Kuaizhou-1A carrier rocket is at Jiuquan Satellite Launch Center.

Launch the "Jilin No.1" high-scoring satellite 02A into space.

At 18: 00 on November 17,

The Kuaizhou-1A carrier rocket was successfully launched in Jiuquan again.

It wasn’t long before "Kuaizhou" set a new record for itself.

At 10: 55 and 16: 52 on December 7, 2019,

Fast boat No.1 A carrier rocket will be launched in 6 hours.

Complete two space launches at the same launch site.

Created a new record for China’s space flight

The speed of "fast boat" is worthy of the name!

Why is "Fast Boat" so fast?

At present, the fast boat series launch vehicles all use solid propellant.

The rocket leaves the factory with solid propellant.

The process and corresponding time of propellant filling at the launch site are saved.

In addition, the "fast boat" avoids the dependence of traditional rockets on the launch tower.

The requirements for launching site support are further reduced.

The launch can be completed with a launch vehicle.

In the past, large launch vehicles were launched.

From assembly to injection of liquid fuel

It takes hundreds of people to cooperate and takes at least two months.

The fast boat rocket can reach the launch site and complete the launch.

It only takes 7 days.

On the day of launch, it was transferred from the technical area to the launch area to complete the launch.

The whole launch area process takes less than 4 hours.

Of course, such a "fast boat" is not enough.

↑ Commercial spectrum of Kuaizhou series launch vehicles

In order to continue to reduce the cost of going into space

In 2020, the clipper rocket initially planned five to eight space launch missions.

Model development

The "Kuaizhou Family" is carrying out the Kuaizhou-1 B carrier rocket.

And the development of Kuaizhou 11 carrier rocket.

Compared with the previous friends

The carrying capacity of Kuaizhou 11 carrier rocket has made a qualitative leap.

The takeoff mass can reach 80 tons.

It is more than twice that of the Kuaizhou-1A carrier rocket.

You can put a limited load of 1.5 tons

Sent to a near-earth orbit about 350 kilometers farthest from the earth.

With the continuous improvement of the type spectrum of the fast boat launch vehicle

China’s space high-density networking/complementary network launch capability will also be further improved.

future

The fast boat will also expand from low rail to high rail.

And gradually into deep space.

Send "blessing" to heaven

Such a hard-core way of greeting the New Year.

Love, love.

Like China Aerospace!

　　Surging crowds, lively platforms, and the joy of returning home … … With the opening of Spring Festival travel rush in 2023, many people rushed home from all over the world with their accumulated thoughts for a year. However, there are such a group of people who bury their thoughts in their hearts and interpret their responsibilities with persistence.

　　From the plateau railway station above 4000 meters above sea level to the high-pressure air pipeline 3 meters underground; From the train room whistling in the cold night to the lonely substation in the mountains, they silently dedicated themselves in their ordinary posts, guarding the railway safety, ensuring the smooth flow of Spring Festival travel rush, and letting thousands of passengers go home safely for the New Year.

　　[Editor’s note]

　　Investigation and research is the source of insight and the basic skill of doing all the work well. Only by focusing on what people think and expect, talking about problems in combination with first-line research and seeking ideas can we form new ideas, new ideas and new methods to solve difficult problems.

　　Can young talents rent a house with complete facilities and really ensure that they can stay with their bags? Are the safety measures in place at the old housing repair site? How to help enterprises simplify the material approval process and realize "one window" handling? Song Jie, Party Secretary and Director of Housing Management Bureau of Jinshan District, Shanghai, helped to build a livable Jinshan through "listening, hearing and asking", trying to achieve "grasping the end, treating the disease, grasping the front end and preventing the disease". Let’s look at Song Jie’s research notes.

　　"Looking at the smell and asking questions" makes up the shortcomings, and the first-line diagnosis and treatment helps livable.

　　"Fuck a thousand songs and then know the sound, watch a thousand swords and then know the device." On the occasion of the investigation and research in Daxing, how can we truly feel the enthusiastic desire of enterprises, the masses and other clients for the construction of livable Jinshan?

　　To this end, I use the diagnostic concept of traditional Chinese medicine for reference, and explore the closed-loop working path of "looking, hearing and asking questions" in the investigation and research, so as to fully reflect the height and temperature of housing management in the construction of livable Jinshan.

　　Living in a place: ensuring housing benefits people’s livelihood

　　"Hope", less meetings and research, more on-site office.

　　Listen to their opinions and suggestions on affordable housing when going to the parks where young talents are concentrated for in-depth investigation. During my visit, I threw out the problems related to affordable rental housing and asked them to put forward their own ideas and conceive future improvement measures.

　　"I hope that in the construction of affordable rental housing, we can always uphold the concept of smart community, create an open and diversified space, and meet all-round life services to the maximum extent." "Is the affordable rental housing fully equipped, and can you really realize the bag occupancy?" During my visit to the park, I was particularly impressed by these points.

　　After learning from Jinshan Housing Management Co., Ltd., Lijing Apartment is the first pure rental housing community project in Jinshan District, and a "Youth Station" has been established, including a reading room, a gym, a canteen for employees and tenants, and a service point for the party and the masses, so as to provide all-round life services for young talents.

Lijing apartment map

　　Since then, I once again came to Lijing Apartment to investigate the operation and maintenance of the "model room" of guaranteed rental housing built in our district. There are 252 sets of one-bedroom households, 128 sets of two-bedroom households and 32 sets of three-bedroom households, all of which are finely decorated and equipped with refrigerators, washing machines, air conditioners and other facilities in all directions.

"Model Room" Diagram of Lijing Apartment

　　Living in security: the old community has a new look

　　"Smell", listen to less reports and visit more on the spot.

　　How to "smell" efficiently, we must grasp the key points and know how to search. I have been wondering whether the safety measures of the old housing repair site have been put in place and can withstand the test of flood season. On the morning of Saturday, April 1, I drove to the Gold Coast repair project site alone and looked at each repaired building carefully.

　　Does the scaffold project meet the specification requirements? Listen to the safety supervision responsibilities of construction, supervision and other units on the spot, and whether a complete indoor ledger has been established? Are there any problems such as construction disturbing people and construction progress? From the conversation with the masses, I feel the residents’ expectation that the old repair work will promote the appearance improvement of the community.

Survey site map

　　Since 2012, when the management measures for residential renovation projects were officially promulgated, how to make the safety barrier stronger and the residents’ life more convenient? On April 3rd, when inspecting the repair sites such as Zhujing and Fengjing, I found that although the construction scaffolding was set up in strict accordance with the standardized requirements, the length of steel pipes of ordinary fastener scaffolding was different, which caused some inconvenience to residents. So, I had an in-depth discussion with the construction and supervision units on how to further strengthen the professionalism and standardization of the old repair and reconstruction work.

　　"Now this scaffold looks as square as a grid, and there are no prominent parts in the bar, so the crossing is safer!" Residents in the community expressed their approval of the socket-type buckle scaffold.

　　Socket-type buckle scaffold not only further ensures workers’ safety, improves the engineering image and prolongs the service life, but also makes the whole scaffold erection and disassembly speed 3-5 times faster than the conventional one due to its reliable two-way self-locking ability and fewer building accessories. At the same time, it can effectively resist the attack of extreme weather when typhoon weather comes, and the scaffold structure is relatively stable in typhoon and rainstorm weather, reducing the risk of safety accidents.

Socket-type plate-buckle scaffold

　　On the basis of ensuring safety, how to realize the "greatest common denominator" in the reconstruction of old houses? Only by adhering to the renovation of roofs, fa? ades, public parts, equipment and facilities, ancillary facilities of residential quarters, and roads, and simultaneously implementing the renovation of mixed rain and sewage, greening and replanting, and steadily promoting the renovation of both internal and external repairs, can we change "new" into "heart".

　　Have something to enjoy: quality housing in yue life

　　"Ask", less old scores, and more reforms.

　　In the past few days, I have visited several new residential projects, such as Fujin Mingyuan, Guantang Jiayuan, Guanhu Mingdi and Hanzhong Hua Ting, to learn about the suggestions of enterprises on the control of high-quality residential construction.

Residential projects visited by investigation

　　With Jinshan’s implementation of the South Transition Strategy and the implementation of the three-child policy, more and more local youths choose to return to their hometowns for employment, and high-end talents are willing to develop in Jinshan, which all affect the development trend of Jinshan housing and pursue quality improvement.

　　Higher quality of life and better living space are the beautiful vision of the people, and should also be the focus and force point of our work. How to firmly grasp the basic point of letting people live in peace, strive to let people live in better houses, truly realize the transformation from shelter to livable choice, and polish the proposition of the times of "Beautiful Bay Area"?

　　"where the way to seek, careful is the treasure." In the next step, we will firmly adhere to the "four first-class" to upgrade the quality of housing.

　　First-class "development" focuses on vitality. Take the initiative to make personalized approval plans for enterprises, open up green channels, implement tolerance acceptance, and adopt drone surveys to improve market magnetism.

　　First-class "design" adds momentum. Guided by the planning, with the goal of "multi-family, full-function, yue life", we put forward the design requirements for new residential buildings, such as the separation of people and vehicles on the ground, the creation of public spaces, and the allocation of cultural and sports facilities, so as to optimize the spatial layout of communities.

　　First-class "building" strong strength. Closed-loop management, do a good job in land transfer inquiry, joint examination of design scheme and acceptance of delivery, and implement standards such as 100% full decoration construction of new commercial housing, 100% full coverage of communication network signals of underground garage, and three-in-one collection of "water, electricity and coal" information to meet the demand of "smart residence".

　　First-class "property" adds charm. Accurate service, focusing on the new era of "beautiful homeland", combined with digital transformation, expand the application of "smart property" scenarios; Introduce high-quality property companies and shape industry benchmarks.

　　Enjoy what you want: excellent business environment and service

　　"Cut", less superficial effort and more precise treatment.

　　This is more and more valuable under the background of optimizing the business environment. Listen carefully to every voice of enterprises and the masses, and record their true feelings about optimizing the business environment one by one: "Go around all morning, just take ‘ A single ’ " "We must submit ‘ in the window. Real estate broker filing ’ Cancel the application, and re-apply to the relevant departments after the approval process is completed ‘ Lease opening report ’ , very inconvenient "… …

　　It is difficult for me to hear these things at the meeting, but they are closely related to residents’ lives and are also the details that we need to pay attention to in our research work. Only by standing from the perspective of the masses and perceiving the problems existing in the process of doing things by the masses, can the leaders "help" better serve the business environment, improve energy and efficiency, and the people can run less.

　　After thinking about how to ensure the quality and effectiveness of examination and approval, win the satisfaction of the masses, and achieve both, we began to implement one-door acceptance of housing management administrative examination and approval items. By opening a one-door acceptance window for the collection of supporting fees for urban infrastructure, enterprises can easily complete the payment procedures for supporting fees offline as long as they submit relevant materials at the window. Enterprises really enjoy the convenience of only "one door" and only "one window" for materials.

　　"I thought I had to make two trips, but I didn’t expect it to be so convenient to change my business now, as long as I submit it synchronously in the window ‘ Real estate broker filing ’ Logout with ‘ Opening report of housing leasing business organization ’ If you apply for these two materials, you can do it. " The first leasing company clerk said this after easily completing the business change.

Industrial park project plot

　　In the real estate transaction, we initiated the "Four Four Services Law", that is, focusing on "policies, projects, packages and windows", ensuring "people’s livelihood, quality, speed and service", striving to be the "shop assistants" of the masses, so that the business-friendly environment can promote the service quality and increase the speed.

　　The person in charge of the project plot of an industrial park praised the "four four service law" of the district real estate trading center: "The surveying and mapping team took the initiative to contact us to inform us of the handling process and materials, and also worked overtime to complete the pre-measurement work of the project, which reduced the time limit for our handling and ensured the smooth development of the project."

　　Looking back on the process of investigation and research, generally speaking, the core of the exploration and practice of "looking, hearing and asking questions" is "not only to grasp the end, to cure the disease, but also to grasp the front end and prevent the disease" In the new journey of promoting the construction of "Three Bay Areas" in the new era, we should make good use of this "wide-angle lens" of investigation and study to nip in the bud and dissolve it in the bud. The knower begins to walk, and the walker knows what to do. As the main body of research, we should give full play to our intelligence and talents, gather the majestic power of building a livable Jinshan, and strive to make the house readable and the city full of temperature.

Special feature of 1905 film network At this year’s Shanghai International Film Festival, many media have clearly noticed that various "so-and-so night" activities are decreasing. Compared with the scene of three or four film companies competing to release films in the past night, from the Bund to Hongqiao, only a few established or powerful companies such as China Film, Shanghai Film, Bona, Wentou, Beijing Culture and Dadi continue to release films and announce their plans for the coming year.

　

The Shanghai Film Festival in the past few years is another scene. Around 2015, during the 10-day Shanghai Film Festival, hundreds of film companies were established, and the number of films could not wait to catch up with thousands. Not only new companies, but also established companies have painted "big cakes", making the guests and guests happy.Now, four years later, most of them are still in the PPT stage.

By 2018 (last year), the number of films released by film and television companies had dropped to about 200. There are probably less than 100 projects concentrated in the hands of companies such as Wanda, Huayi and Shangying. It’s just that how many of these 100 films were finally released, it still needs to be counted to see what happened to last year’s film list.

　

Shanghai Film Group: Some projects are cooled, and most of them are animated.

　

As the host of Shanghai International Film Festival, it is normal for Shanghai Film Group to release the film list during the film festival. A few years ago, the number of new films released by Shanghai Film Group was quite large, and their main creations were quite heavy, such as Wong Kar-wai’s "The Code of Famen Temple" by Tsui Hark, directed by Cao Baoping and starring Chen Daoming, etc., but now there is no further news.

　

By 2018, the film list of Shanghai Film Group will be relatively calm. It is a cooperation with Tencent Pictures. It was released in June and will be released in the summer.

There is a shadow of Huayi behind it. One of the two films appeared in the main competition unit of the Shanghai Film Festival that year, and the other just went to Cannes to participate in the competition, and both were released in 2018.

　

　

The special feature of the film list is the emergence of repair projects — — Director Xie Jin produced a dubbing version of Shanghai dialect; Classic cartoons have also been restored. Although these two films have been restored, there is no specific national release time at present.

　

As for other animation projects, they have been released; The combination of "Ten Lengs" has not heard the wind yet. And there is no new news for the time being.

WANDA CINEMAS: The degree of completion is quite high

　

Last year, Wanda Pictures released a list of 19 films. Xiao Dianjun counted, and as many as 14 films have been released+filmed. It’s just a project controlled by Wanda, and the popularity is very limited.

　

It’s already on. Combining word-of-mouth and box office, the best performance is probably the "fast brother" with a small one.

　

Fortunately, Wanda still has Legendary Pictures’s move, and its performance in China is also good.

　

On the other hand, the unreleased films in Wanda’s film list are still progressing well. Simon west’s "Star Craft" has been launched, starring Zhang Hanyu, Jiang Wu and Celina Jade, and it is currently scheduled for 2020.Also set the file early next year’s New Year’s Day.It will be shown this summer.

　

Legendary Pictures’s part of the film list has already been filmed. It has also been taken over by Villeneuve, and Zhang zhen, "Sweet Tea" and other stars have confirmed their joining.At present, Wanda’s film list last year has been digested almost, and its overall performance is quite excellent. On the evening of June 19th, Wanda also released the latest film list in Shanghai. In addition to the silent witness and liberated films to be released this year, the sequels of big IP such as Ghost Blowing Lights and Searching for Dragons have also aroused many expectations.

　

Huayi Brothers: There are a lot of unknowns.

　

Although Huayi is deeply mired in the mud, the plans for 20 new films released last year are actually almost consumed, and most of them have been realized. Just compared with other companies, Huayi also counted the films it invested overseas. These films have been released overseas, but it is still unknown whether they will be released in China.

　

At present, 20 films have been released, completed and at least 16 are being filmed. However, the six films released have to be described as "bleak", and the highest box office is Tsui Hark’s Di Renjie 3: The Four Kings. However, compared with the large amount of investment, the box office of 600 million may be just a drop in the bucket.

　

　

Several films invested by Huayi overseas were also released last year. However, whether these films are or look more like films that filmmakers like, it is a bit difficult to sell them in China, not to mention whether there is any intention to introduce them to China.

　

As for other projects, the more gratifying news is that "Yin Yang Shi" has been renamed and finished this year; It has long been completed with back-to-back shooting, but according to the quality of the latter, Huayi estimates that there are other considerations; Y?jir? Takita’s also finished at the end of last year.

　

　

As for Yu-sheng Tian’s works that are not named in the film list, let’s just say that they will be released immediately. After all, there is also Huayi Investment. Lu chuan’s is also being filmed.as forLeste ChenofCycleAlthough it has been reported before.JohnnyJoin, the news of starting in May, butChen ZhengTao himself said that the launch of "Cycle" has been postponed.

Lechuang Entertainment: "Dare to Dream"

　

From 2018 to now, Lechuang has been waiting for a movie that can save himself, but all the films released are dumb. Zhang Yimou has only 600 million, and its reputation is worrying. But last year, Le Chuang still released 28 film projects.

It can only be said that Lechuang is still a "bold dream" company, with not only many films, but also emphasis on serialization. Not only the condor heroes and the legendary swordsman series, but also Kuafu Day by Day should be made into a series of movies.In the end, how much of this film list will eventually be realized, and how many of the 22 series in 28 projects can wait for the first one to start, let us wait and see.

　

Earth Movie: Last year’s movie is also this year’s.

　

Last year, Dadi Film announced a total of eight projects, and two films were released: and.Five more films appeared on this year’s film list:And Mirror Man.Then disappear from this year’s film list.

　

　

Only two films were released, Asura was very tragic, and there was no news after three days of release. The theme of "Junior" is small and it is difficult to attract more audiences. It can be said that it will take a long time for the earth to move upstream of the film industry.As for five films, such as Sweet Potato and Rice, judging from this year’s film list, they have all been completed and are now waiting for the release opportunity.

This year, the distribution resources of Dadi movies are tilting towards When the Wind Comes Again — — One is the selected film of Cannes Film Critics Week this year; One is an epic film co-produced by Tony Leung Chiu Wai and Aaron Kwok.Nowadays, there is no shortage of cinemas and distribution, only mature directors and good projects. Probably train young directors and bind themPhilip YungIt is the next game of this company that started from the cinema.

At present, fewer and fewer companies dare to do PPT during the film festival, and the market is becoming more and more calm. However, it is not a bad thing to wash the sand in big waves, and what remains is mostly good projects that are really worth shooting. As the saying goes, you don’t know who is swimming naked until the tide recedes.

　

　　The French government announced on March 24th that it would ban government personnel from using TikTok, Twitter, Instagram and other entertainment applications on mobile phones due to concerns about data security.

　　According to Al Jazeera and Associated Press, on March 24th, local time, the French Ministry of Reform and Public Administration issued this notice, saying that the ban would take effect immediately. Stanislas Guerini, French Minister of Reform and Public Administration, wrote in a statement: "In order to ensure the network security of our government and civil servants, the government decided to ban civil servants from using TikTok, Twitter, Instagram and other entertainment applications on professional telephones. These entertainment applications cannot serve national administration and may pose a threat to data security. "

　　Grini added that for several weeks, many European allies and international partners of France have taken measures to restrict or prohibit their government workers from downloading, installing or using TikTok.

　　According to Reuters’s previous report, on February 23rd, the European Commission banned its employees from using TikTok for office work on security grounds. On February 27th, the Canadian government announced that TikTok； would be banned from all mobile devices of Canadian government departments. On February 27th, the White House also asked government agencies to ensure that TikTok is disabled on their federal equipment and systems within 30 days.

　　According to a report by The Wall Street Journal on March 15th, a person familiar with the matter disclosed that the Biden administration of the United States threatened TikTok and asked ByteDance to sell its shares in TikTok, otherwise the application would be banned in the United States. Shou Zi Chew, CEO of TikTok, said that the so-called "security risks" in the United States could not be solved by cutting TikTok from China. He welcomed feedback from all walks of life on the risks in TikTok and stressed that no risks could be solved.

　　On March 16th, China’s Foreign Ministry spokesperson Wang Wenbin responded at a regular press conference that data security should not be a tool for individual countries to generalize the concept of national security, abuse state power and unreasonably suppress enterprises in other countries. So far, the United States has failed to produce evidence to prove that TikTok threatens the national security of the United States. It should stop spreading false information on data security issues, stop unreasonably suppressing relevant enterprises, and provide an open, fair, just and non-discriminatory business environment for enterprises from all countries to invest and operate in the United States.

CCTV’s large-scale media activity "Hundred Years and Hundred Cities" came to Yantai City, Shandong Province. Yantai was one of the first coastal open cities in China in 1984, and it was a new coastal city rising from the saline-alkali wasteland.

　　The reporter came to the Folaishan Citizen Cultural Park in Yantai Economic and Technological Development Zone, which is only more than 1000 meters away from the seaside. The sea has formed its high-quality ecology and provided natural location advantages for urban development here.

　　After more than 30 years of vicissitudes, the once saline-alkali beach has become a modern coastal new city. At present, 125 Fortune 500 projects have taken root in Yantai Development Zone, and the output value of the two leading industries of machinery, automobiles and electronic information has exceeded 100 billion yuan. Strategic emerging industries have risen strongly, and two industrial clusters, advanced structural materials and biomedicine, have been selected as the first batch of 66 national strategic emerging industrial clusters in China, and the total production capacity of MDI materials ranks first in the world.

　　Liu Jianmin, Deputy Secretary of the Working Committee and Deputy Director of the Management Committee of Yantai Development Zone: Like many development zones in China, the development model of Yantai Development Zone is to expand the secondary production, promote the integration of the tertiary production and the production city, and finally rise from a barren beach to a new coastal city.

"Separation of the return capsule" and "entry into the atmosphere" … accused the hall operator of staring at the screen, and the measurement and control instructions came one after another. With three huge red and white "umbrella flowers" in full bloom over Jiuquan Dongfeng recovery landing site, the return capsule slowly swayed and landed on the ground. The return capsule is getting closer and closer to the ground, six airbags are opened, and the landing buffer is smooth, and the flight test mission is a complete success!

The moment the return capsule landed smoothly, warm applause immediately resounded through the hall in beijing aerospace control center.

At 13: 49 on May 8, the return capsule of a new generation of manned spacecraft test ship, which was developed by the Fifth Research Institute of China Aerospace Science and Technology Corporation, successfully landed in the predetermined area of Jiuquan Dongfeng Recovery Landing Site, which marked the complete success of the test ship’s flight test mission and also meant that China’s manned space industry opened a new chapter.

Seven key technologies of perfect verification

The new generation manned spacecraft is a new generation of round-trip transport aircraft for China’s near-earth space station operation and manned lunar exploration. It has the characteristics of high safety, high reliability, multi-task adaptability and modular design, and adopts a new configuration of "return cabin+service cabin". Spacecraft can be used in low-earth orbit to support the construction of China’s space station, and it is also competent for the exploration of more distant deep space such as manned landing on the moon. It also has the powerful ability of "transporting people+transporting goods" and can transport 6-7 astronauts at a time when performing low-earth orbit tasks.

The new generation of manned spacecraft adopts many new technologies and products, especially in terms of reliability, safety, comfort, economy and intelligence.

The main goal of this mission is to verify the correctness of the new generation manned spacecraft scheme. It is understood that in order to verify more technologies and equipment, the development team of the Fifth Academy arranged high-density flight events for the test ship. During the on-orbit flight, the test ship has to complete dozens of key actions and carry out a number of carrying tests. It can be said that every minute is fully scheduled.

From successful launch to safe return, the test ship performed perfectly. For the Fifth Academy, seven key technologies that they are most concerned about and related to the success or failure of the mission have been verified one by one, which points out the direction for the development of new spacecraft in the next stage.

A new generation of manned spacecraft under test

These seven key technologies are:

In the on-orbit flight stage, the first single-component non-toxic engine with the highest thrust in the world successfully completed its debut.The HAN propellant used in this engine has the advantages of non-toxicity, pollution-free, low freezing point, high density, high specific impulse and low maintenance cost. It will completely replace the existing propellant in the future and further improve the safety of astronauts.

The maximum volume surface tension tank used for spacecraft in China for the first time performed perfectly.This tank adopts aluminum alloy lining and composite material winding structure, which has more loading capacity and can provide greater orbital maneuverability for the test ship. During the on-orbit flight, the test ship easily completed many orbit changes and entered the large elliptical orbit, which created sufficient conditions for high-speed reentry and return with large reentry angle.

A more comprehensive integrated electronic system is worthy of trust.During the mission, the system successfully completed the functions of the whole ship bus management, time system management, data storage, contact signal processing and thermal control management, which made the spacecraft run more efficiently.

Smarter autonomous track control technology plays an outstanding role.During the on-orbit operation, the attitude control engine performs attitude control, maintaining the attitude stability of the three-axis to the ground and during orbit change and braking; The orbit control engine changed its orbit several times, and successfully executed the return braking, which accurately controlled the test ship to complete the space flight.

In the reentry and return phase, the new heat-proof structure and materials adopted for the first time have been tested.. The whole thermal protection structure maintains a very high thermal protection efficiency on the basis of reducing the weight by more than 30% year-on-year. The new lightweight heat protection material not only withstood thousands of degrees of high temperature ablation during reentry and return, but also protected the safety of the return cabin. Moreover, the heat protection structure adopts the detachable replacement design for the first time, which can effectively improve the reusable rate. After returning, only one "physical examination" is needed, and a new heat-proof structure is replaced, so that the return capsule can be put into the next mission.

For the first time, the group parachute pneumatic deceleration and airbag landing buffer technology were adopted to escort home.. After the return capsule entered the atmosphere and reached the specified height, two deceleration umbrellas and three main umbrellas were opened in turn, which successfully reduced the speed of the return capsule from "aircraft flight speed" to "automobile city driving speed"; Before landing, six airbags were inflated and opened to help the cabin "soft landing" smoothly, ensuring the safe and complete recovery of the return cabin to the greatest extent.

Tailor-made on-orbit data acquisition system provides scientific support for future development.During the mission, the system obtained the impact load of ship-rocket separation and the load environment of carrying launch, on-orbit flight and return landing through various sensor networks. By measuring the pressure and temperature of the characteristic points on the bottom and sidewall surface of the return capsule, the aerodynamic and thermal characteristics of the return capsule during high-speed reentry are obtained. These valuable data will provide important reference for the development and optimization of subsequent models of new spacecraft.

The new generation of manned spacecraft is larger in size, more functional, more intelligent and autonomous, and adopts reusable technology.

China manned spacecraft technology from running to running.

Manned space flight represents a country’s comprehensive national strength and scientific and technological strength, and can promote the development of multidisciplinary and multi-technical fields. According to official information, China began to explore manned space technology in the 1960s. After the successful launch of the Dongfanghong-1 satellite, the manned space program codenamed "Project 714" was fully promoted, and the development plan of the "Shuguang-1" manned spacecraft of this project was officially launched. However, due to various reasons, the development of the "Shuguang-1" manned spacecraft finally stopped.

In 1992, China’s manned spaceflight project was officially launched. In the early morning of November 20, 1999, the Shenzhou-1 spacecraft was launched, and the curtain of China’s manned space flight slowly opened. On October 15th, 2003, Shenzhou 5 was launched. Astronaut Yang Liwei started the return procedure after flying around the earth for 14 times and 21 hours in Shenzhou 5, and returned smoothly, realizing Chinese’s dream of flying for thousands of years.

"Dawn One" spacecraft looks like a bullet head.

Since 1999, China has launched a total of 11 shenzhou spaceship, including 6 manned spacecraft and 5 unmanned spacecraft, and also launched 2 space laboratories, with 11 China astronauts and 14 people completing space trips, with the longest in-orbit time reaching 30 days; Achieve multiple firsts-astronauts’ first space outing, first rendezvous and docking, first space teaching …

At the press conference of the first mission of the Long March V B carrier rocket held on the evening of May 5, Ji Qiming, assistant director of the China Manned Space Engineering Office, introduced that China’s space station will be completed around 2022, with a total of 12 missions planned. After this mission, the core module and the experimental module will be launched successively to carry out on-orbit assembly and construction of the basic configuration of the space station; During the period, it is planned to launch four Shenzhou manned spacecraft and four Tianzhou cargo spacecraft to carry out crew rotation and cargo replenishment.

Facing the mission demand of China’s manned space flight to further deep space, in 2015, the Fifth Academy demonstrated and put forward the plan of developing a new spacecraft test ship to carry out high-speed reentry flight test. From January 2017 to December 2019, in just three years, the Fifth Academy completed the scheme design, product development, whole ship assembly, comprehensive test and large-scale test, broke through a large number of key technologies, and built this new spacecraft test ship from scratch, carrying new hopes and opening up new "heavenly roads".

Shenzhou VII astronauts left the cabin for the first time.

After mission verification, the main technical indicators of the new generation manned spacecraft test ship have reached the international advanced level. The Paper (www.thepaper.cn) learned from the Fifth Academy that compared with the international advanced space shuttle spacecraft, China’s new generation of manned spacecraft is no less capable, and they all have the ability to adapt to multi-task requirements, greater orbital maneuverability, and land and water landing capabilities.

The new spacecraft is more intelligent, and the GNC system of the spacecraft can independently control the flight of the spacecraft, which further improves the autonomous operation ability, improves the on-orbit survivability and application potential, and reduces the maintenance and operation cost, which is of great significance to the follow-up deep space exploration and the development of manned space models in China. The new spacecraft can also "see a doctor" for itself. During the flight, it pays close attention to its own health in real time. Once there is a problem, it "diagnoses" itself through the intelligent algorithm of the system, finds the lesion and removes it temporarily or permanently.

The new spacecraft is more cost-effective. The new spacecraft can be reused, and the use cost is greatly reduced. In order to reduce the cost of entering space, the return cabin of a new generation of manned spacecraft is designed by aerospace engineers to be reusable, and some high-value equipment, such as star sensors and computers, are adjusted from service cabin to return cabin after optimization design, so that they can be recycled after returning with the return cabin. A new lightweight thermal protection structure independently developed by China is coated outside the return capsule. After the mission is completed, only the lightweight thermal protection structure needs to be replaced, and the manned space mission can be carried out again after strict inspection. In order to achieve multi-functional use, the new spacecraft adopts a modular design of "building blocks". Different mission requirements can be completed through the same return cabin and different service cabin configurations.

The successful mission of the test ship indicates that a new generation of manned spacecraft in China has taken shape. It is understood that the Fifth Academy will, in combination with the mission requirements, carry out in-depth demonstration of the overall scheme of a new generation of manned spacecraft, improve and develop a new generation of manned spacecraft with high carrying capacity and cargo transportation capacity as soon as possible, and adapt to the near-earth space station and manned deep space exploration mission, so that China’s manned space transportation technology can fully realize the leap from running to running, so that Chinese’s pace of exploring space can be more stable and further, and contribute more to the early realization of the great dream of building a space power.

　　Yale University scientists revealed the gradual process of quantum transition through a high-speed photography technology. Quantum jump has once again become a buzzword, and it has set off a debate about whether quantum mechanics is random or continuous.

　　As a theory to understand the atomic scale world, quantum mechanics has a core concept that is extremely radical, bold and counterintuitive, and even becomes a buzzword, that is "quantum transition". Most pioneers of quantum mechanics believe that quantum transitions are "random and instantaneous".

　　A new experiment shows that this is not the case. The research was completed by Zlatko Minev, a graduate student of Mike de Vorreith Laboratory of Yale University. He and his colleagues revealed the gradual process of quantum transition through a high-speed photography technique. This achievement was recently published in the journal Nature.

　　The significance of the experiment may be far more than that: researchers use the high-speed detection system to "catch" the quantum transition when it is about to be marked, and then reverse it to restore the system to its initial state.

　　As a result, the inevitable stochastic processes in quantum physics are now proved to be controllable — — Can people really control quantum?

　　Debate on quantum transition

　　Unlike Bohr and Heisenberg’s quantum theory, Schrodinger believes that there is no quantum transition.

　　In the mid-1920s, physicists niels bohr, Werner Heisenberg and colleagues established quantum theory. Bohr first proposed the concept of quantum transition, but it was not observed in the laboratory until the 1980s. This theory is collectively called Copenhagen interpretation.

　　Bohr proposed earlier that the energy levels (i.e. energy states) of electrons in atoms are quantized, that is, electrons can only use certain energy levels, while all intermediate energy levels are forbidden. He assumes that electrons change their energy by absorbing or releasing light quantum particles, that is, photons, and the energy of photons matches the energy gap between the allowed electronic States. This explains why atoms and molecules can absorb or release light with specific wavelengths. For example, many copper-containing salts are blue, while sodium lamps emit yellow light.

　　In a set of mathematical theories developed by Bohr and Heisenberg, which can explain quantum phenomena, Heisenberg listed all the allowed quantum states, suggesting that the transitions between these quantum states are instantaneous and discontinuous. The concept of instantaneous quantum transition has become a basic concept in Copenhagen.

　　However, the Austrian physicist Erwin Schr?dinger, another founder of quantum mechanics, did not agree with this view. In Schrodinger’s theory, he represented quantum particles by wave-like entities of wave functions. Their changes were gentle, and they changed continuously with time, just like gentle waves on the vast sea.

　　Schrodinger believes that things in the real world will not suddenly change greatly without spending a little time, and discontinuous quantum transitions are just an illusion in my mind. In an article entitled "Is there a quantum jump" published in 1952, Schrodinger firmly replied: "No."

　　The focus of the debate between them is not just whether Schrodinger likes sudden changes, but that Bohr and others claim that quantum transitions will occur randomly, but they can’t say why it is that particular time. This is like a result without reason, which is undoubtedly a great challenge to the law of natural causality.

　　In order to explore deeply, people need to observe a single quantum transition. In 1986, three international research teams reported that they observed quantum transitions in a single atom suspended by an electromagnetic field: the atom switches back and forth between a "bright" state and a "dark" state, in which the atom emits a photon, while in a "dark" state it does not emit photons randomly; The atom stays in one of these states for a few tenths of a second to a few seconds, and then jumps again.

　　Since then, people have observed such transitions in different systems, including the transition of photons between different quantum states and the transition of atoms of solid materials between quantized magnetized states. In 2007, a French research team reported that a transition was found, which was in line with what they described as the process of "a single photon from birth, activity to death".

　　In these experiments, the transition really seems to be sudden and random, because even if the quantum system is monitored, no one can tell when the transition will occur, and there is no specific image showing the transition.

　　Capture quantum transition

　　The experiment of Yale University can not only predict the transition, but also reverse it.

　　How exactly did Yale University do this experiment?

　　Generally speaking, they use a special method to indirectly monitor superconducting artificial atoms, that is, three microwave generators are used to irradiate atoms enclosed in an aluminum three-dimensional cavity. This dual indirect monitoring method developed for superconducting circuits enables researchers to observe atoms with unprecedented efficiency. They found that every time a quantum jump occurs, a tiny photon disappearance phenomenon will occur, which can be regarded as an early warning signal.

　　Minev, the first author of the paper, said: "Using this phenomenon, we can not only predict the transition, but even reverse the transition."

　　The researchers said that although quantum transitions are discrete and random in the long run, preventing quantum transitions means that the evolution of quantum States is deterministic to some extent, rather than completely random; Transitions always occur from their random starting points in the same and predictable way.

　　The quantum system used by researchers is much larger than atoms, and it is composed of cables made of superconducting materials, sometimes called "artificial atoms" because they have discrete quantum energy states, similar to the electronic states in real atoms. Transitions between energy states can be induced by absorbing or releasing a photon, just like electronic transitions in atoms.

　　Some scientists believe that this research may also be applied to quantum computing error correction. However, the real value of the experimental results lies not in any practical application, but in our understanding of the quantum mechanical system.

　　How can Schrodinger’s cat be saved

　　Through correct monitoring, we can observe an early warning signal and take action.

　　Schrodinger’s cat paradox explains the concept of "superposition" in quantum physics (that is, two opposite states can coexist) and unpredictability: a cat is placed in a sealed box with a radioactive source and a poison in it. If one atom of radioactive material decays, it will release poison. According to the superposition theory of quantum physics, before someone opened the box, the cat in it was both alive and dead, that is, in the superposition state of two States. Once the box is opened and the cat’s life and death are observed, its quantum state will change immediately and become one of "dead" or "alive".

　　Yale University’s research shows that an early warning signal can be observed during quantum transition, which makes Schrodinger’s cat saved.

　　Because the decay of nuclear is a random event, physicists only know the probability of its decay, and can’t know when it decays. If the nucleus decays, releasing alpha particles, triggering the electronic switch, the hammer falls, smashing the poison bottle and releasing cyanide gas, the cat will be poisoned.

　　If physicists don’t open the lid of the secret room, it is uncertain whether the cat is dead or alive, and it is in a superposition state of both death and life. Only when the lid is lifted can we know for sure whether the cat is dead or alive. In this way, the microscopic uncertainty principle has become a macroscopic uncertainty principle.

　　Yale University researchers use an indirect observation method in the experiment, which is also a "weak measurement" method widely used in the field of quantum information, and will not disturb the observed object. Researchers believe that the transition of a particle is neither as sudden nor as random as previously thought, and the evolution of quantum state is deterministic rather than random to some extent. Theoretically, through correct monitoring, we can definitely find the warning of the coming disaster, and take action before the disaster, and remove the poison bottle at the moment when the nuclear decay is predicted, so Schrodinger’s cat was saved. Minev said: "The quantum transition of atoms is somewhat similar to volcanic eruption. In the long run, they are completely unpredictable. Nevertheless, through correct monitoring, we can accurately get the early warning of the impending disaster and take action before it happens. "

　　The foundation of quantum mechanics has not been affected.

　　The paper clearly shows that the experimental results are in good agreement with the theory of quantum mechanics.

　　According to von Neumann’s summary, quantum mechanics has two basic processes, one is deterministic evolution according to Schrodinger equation, and the other is random collapse of quantum superposition state caused by measurement. Schrodinger equation is the core equation of quantum mechanics, which is deterministic and has nothing to do with randomness. Then the randomness of quantum mechanics only comes from measurement.

　　This randomness of measurement is what Einstein can’t understand. He used the metaphor that "God can’t roll the dice" to oppose randomness of measurement. However, countless experiments have confirmed that the result of directly measuring a quantum superposition state is random. In order to solve this problem, many interpretations of quantum mechanics have been born, among which three mainstream interpretations are Copenhagen interpretation, multi-world interpretation and consistent historical interpretation.

　　According to Copenhagen interpretation, measurement will lead to the collapse of quantum state, that is, quantum state will be destroyed instantly and fall to an eigenstate randomly; According to the multi-world interpretation, every measurement is a division of the world, and the results of all eigenstates exist, but they are completely independent of each other and do not interfere with each other. We are just randomly in a certain world; Consistent historical interpretation introduces quantum decoherence process, which solves the problem from superposition state to classical probability distribution. However, in choosing which classical probability, it still goes back to the debate between Copenhagen interpretation and multi-world interpretation.

　　Professor Li Chuanfeng from the Key Laboratory of Quantum Information of China Academy of Sciences told the Science and Technology Daily reporter that these interpretations predicted the same physical results, and they could not be falsified, so the physical meanings were equivalent. Therefore, the academic circles mainly adopted Copenhagen interpretation, that is, the word collapse represented the randomness of measuring quantum states.

　　"The experiment of Yale scholars has not affected the foundation of quantum mechanics, that is, the inherent uncertainty of quantum mechanics." Li Chuanfeng said that the quantum transition is certain for the wave function itself, just like a dice, and it is certain that it can’t roll 7 points. The wave function can calculate how the particle probability cloud in quantum state evolves, but once the measurement problem is involved, the Schrodinger equation cannot be solved. The only way is to calculate the probability of particles, such as position probability, momentum probability and so on.

　　"In fact, as early as 1986, a research team confirmed through experiments that quantum transitions take time. Yale University found that quantum transitions not only take time, but also send out an early warning signal before each transition. " Li Chuanfeng said that this is like saying that someone wants to jump long, but it is impossible to predict when he will take off, but before jumping forward, his body will lean forward and raise his arm to swing back and forth, and there is a definite causal relationship between these two things. Just hit him as soon as he raises his arm, and he won’t jump. However, when this early warning signal appears is still probabilistic. As for the "overturning quantum mechanics and overturning the uncertainty principle of quantum mechanics" circulating on the Internet, it is not involved in the experiment at all, and it is clearly stated in the paper that the experimental results are in good agreement with the theory of quantum mechanics.
