The 2023 "Shuang Shuang Guiyang" fitness trail league around the city ended, and culture and nature connected in series to carry health and beauty.












On July 31st, the General Office of the State Council forwarded the Notice of the National Development and Reform Commission on Measures to Restore and Expand Consumption (hereinafter referred to as the Notice), clearly enriching the consumption of cultural tourism and vigorously developing rural tourism.
Encourage all localities to formulate and implement policies such as ticket reduction and exemption in scenic spots and free opening in off-season.
In terms of enriching the consumption of cultural tourism, according to the Notice, we will fully implement the paid vacation system, encourage off-peak vacations, flexible work and rest, and promote holiday consumption. Strengthen the integration of regional tourism brands and services and actively hold cultural and tourism consumption promotion activities. Improve tourism infrastructure, strengthen the construction of smart scenic spots, and improve the quality of tourism services. Encourage all localities to formulate and implement policies such as ticket reduction and exemption in scenic spots and free opening in off-season. On the basis of ensuring tourists’ right to choose independently, we will support different regional scenic spots to cooperate in implementing the joint ticket mode, and encourage scenic spots to implement the one-ticket, multiple-time and multi-day use system in combination with the actual situation to better meet the diversified needs of tourists. Promote the innovation and development of night travel consumption norms, guide museums, cultural centers, amusement parks, etc. to extend their opening hours, and support the construction of a "24-hour living circle" in conditional areas. Create a new space for immersive performing arts and build a new gathering area for cultural tourism consumption.
Cheng Chaogong, chief researcher of Tongcheng Research Institute, pointed out that based on the new situation of the recovery of the cultural tourism market, while continuing the previous promotion fee policies such as ticket discounts, the Measures focused on improving the quality and expanding the supply side. The first is the supply of holidays. The "Measures" put forward "fully implementing the paid vacation system, encouraging off-peak vacations and flexible work and rest". Flexible holiday supply will drive the tourism consumption of illegal holidays, and it is expected to release more consumption kinetic energy from the top-level design. Secondly, the potential of the existing cultural tourism services is tapped and upgraded, and the service scenarios are optimized, such as appropriately extending the business hours of relevant cultural tourism sites, providing joint ticket services for multiple scenic spots, and using one ticket for multiple days. These measures are aimed at better matching the diversified needs and further enhancing consumer confidence with a better service experience. Furthermore, it is the right time to encourage the supply expansion of high-quality cultural products, especially to increase the supply of high-quality cultural products such as drama festivals, music festivals, art festivals, animation festivals and concerts, which will effectively alleviate the current situation that the supply of high-quality performing arts products is in short supply, thus further releasing the consumption potential of the cultural tourism market, and the tourism industry in various places will gain more increments, and the expansion of service consumption in various places will also be strongly supported.
Zhou Weihong, deputy general manager of Spring and Autumn Tourism, said that the consumption of cultural tourism should occupy a very important proportion in the current "holiday" economy structure, so it is necessary and timely to introduce detailed policies from multiple angles to "promote" domestic demand again.
Zhou Weihong pointed out that the consumption of cultural tourism in summer has entered the next stage, and it will be the off-season of cultural tourism by the end of August, so it is necessary to extend the "holiday" through policies to promote consumption. At the same time, a lot of the consumption of cultural tourism in summer is still "rigid". The next off-season travel is to improve the cost performance and compound ratio through the combination of tickets, increase the night show in Wenbo venues, increase the service time, and increase the expenditure on leisure and entertainment in cultural tourism consumption.
Promote the implementation of rural residential service certification, and cultivate and publish a number of graded tourist homestays.
In terms of vigorously developing rural tourism, the Notice pointed out that the experience of "Ten Million Projects" in Zhejiang should be popularized to build livable and suitable villages. We will implement the rural revitalization plan of cultural industry empowerment, protect and inherit excellent local culture, revitalize and tap rural cultural tourism resources, and improve the efficiency of rural cultural tourism facilities. Promote the implementation of rural residential service certification, cultivate and publish a number of grade tourist homestays, and create a number of quality homestays. Support business entities to develop products such as forest homes, forest trails, healthy oxygen bars, starry sky camping, motels, etc., and create a number of new formats such as beautiful countryside, landscape agriculture, farming experience, outdoor adventure, outdoor sports, research travel, etc. according to local conditions, and expand rural eco-tourism and leisure travel.
Zhou Weihong pointed out that vigorously developing rural tourism can not only meet the natural needs of urban and rural residents in tourism consumption at present, but also make them happy through contact and experience with nature, land and folk customs. It can also help farmers to increase their income through the development of the tourism industry chain, and continue to stabilize and expand the achievements of rural revitalization. This is the best policy for both sides.
Cheng Chaogong said that the requirements for developing rural tourism in the Notice are essentially to provide support for the expansion of tourism consumption from the supply side. On the one hand, the increase of high-quality rural tourism products is of positive significance for further releasing the leisure and holiday demand of urban residents, on the other hand, it is also an important starting point for promoting the transfer of urban consumption to rural areas, and will also have a driving effect on expanding consumption in rural areas.

Special feature of 1905 film network Once upon a time, it was just an ordinary first-year Hogwarts textbook, which passed by in the middle of the class, and even many fans ignored its existence.
In the novel, this easy-to-understand first-year required reading was published by Silent Book Company (yes, that’s Silent) in 1927 and has been published to the 52nd edition.

Cover of Fantastic Animals in Chinese and English (Second Edition in Chinese)
In reality, J.K. Rowling published a realistic version of Fantastic Beasts and Where to Find Them in 2001 under the guise of Newt Scarmand. This 77-page mini-book not only introduces 72 magical creatures, but also is filled with notes of Harry, Ron and Hermione, some of which are their personal experiences of animals, and some are original works that only senior fans can understand.

The most interesting thing in Fantastic Beasts and Where to Find Them is the interaction and spit of the three protagonists.
It is worth mentioning that albus dumbledore prefaced the book with his own handwriting, reminding Muggle readers that "these interesting animals are fictional and won’t hurt you", and concluded with the motto of Hogwarts: "Never provoke a sleeping dragon".
He has also published books and made movies, and one shot is a five-part series. It is self-evident that "Aunt Luo" has a preference for magical animal series. It’s just that Xiao Dianjun can’t help complaining about other books in Harry Potter. According to the statistics of foreign Harry Potter Wiki, there are as many as 303 books in Harry Potter novels and official games, and many of the stories behind them are more exciting than Fantastic Animals.
These books are former movie protagonists.
The first horcrux: tom riddle’s diary

It is far-fetched to count a diary as a book, but as a paper carrier and one of Voldemort’s horcruxes, its position in the Harry Potter series can not be ignored.
Although it is not a book, it records Voldemort’s illustrious life experience as the heir of Slytherin, and it also carries tom riddle’s memories of Hogwarts and Dumbledore’s constant chaos. In several films, christian coulson and Frank Dillane play the young tom riddle Yan Yan off the charts, which makes people think that it would be a good choice to write a book and make a film for the young Voldemort.

Frank Dillane (left) andChristian coulson (right) has beenPlay the young tom riddle.
"Half-Blood Prince" Appears: severus snape’s Potions Book
In the movie, Harry got a second-hand "Advanced Potions Making" owned by the self-proclaimed "Half-Blood Prince". Thanks to the dense annotations in the book, Harry became a "potions genius" in his class, and learned a lot of spells from it.

There are different opinions about whether Harry got this book by chance or Snape left it to him on purpose, but it is through this book that they established an inseparable connection and pushed Snape, a contradictory and warm figure, to the stage.
How many people were moved by Professor Snape’s "look at me" (look at me) on his deathbed. Snape’s chance to return to the big screen must be the wish of many movie fans, but the image of the professor in our hearts has already overlapped closely with that of alan rickman. With the death of the professor, I’m afraid we will never see the "half-blood prince" on the screen again in a short time.
The Source of Evil: Decryption of Cutting-edge Dark Magic
In Harry Potter and the Deathly Hallows, Hermione used accio to summon the Decryption of the Cutting-edge Dark Magic from Dumbledore’s office to her dormitory. The book contains a detailed introduction to horcruxes and how to make them. This book was once banned by Dumbledore, because it was from this book that young tom riddle read about horcruxes. It can be said that this book is not only a key to solve many mysteries, but also the beginning of all subsequent evils and human tragedies.
The key to solving the puzzle: The Story Collection of Poems and Peas
Cover of the Chinese and English Version of Stories of Poems and Peas
The Story Collection of Poems and Peas is similar to Andersen’s Fairy Tales in the magical world, and the storyline is closely related to the novel Harry Potter series and independent. It is a book left by Dumbledore to Hermione in Harry Potter and the Deathly Hallows, the last chapter of which is — — The Legend of Three Brothers contains the important clue of "Deathly Hallows": the person who owns elder wand, Resurrection Stone and invisibility cloak at the same time will become the master of death and have the power to dominate death. Harry finally killed Voldemort with an elder wand.

These books may look good in movies.
Hogwarts: A History of the School

Cover and emblem of Hogwarts: A History of the School
Rowling introduced the book on Pottermore website as "There is a detailed history and story of Hogwarts School of Witchcraft and Wizardry here". The title of the book alone has endless attraction, and it is the spiritual holy land of fans — — There are so many historical questions that need to be answered by this book, such as what kind of stories are hidden behind Hogwarts, what kind of grievances and enmities exist between the four founders, and how the contradictions between salazar slytherin and the other three in The Chamber of Secrets developed.
Unfortunately, this book has never taken shape, and the existing English and Chinese versions are novels of the same name created by fans. In the original novel, A History of the School is one of Hermione’s favorites, and famous sentences in the book are often mentioned by her, such as the magic on the roof of Hogwarts, the inability to "apparate" and "apparate" in the school area, and the fact that boys who know magic can’t enter the girls’ dormitory, otherwise the stairs will automatically become slides and so on.
The Magic Quidditch Ball

The cover of The Magical Quidditch Ball in Chinese and English (second edition in Chinese)
Quidditch, a national sport in the magical world, can be said to be one of Aunt Luo’s greatest inventions. The Magic Quidditch Ball is also one of the few books published in the real world. In 2001, it was published together with Fantastic Beasts and Where to Find Them. On the author, J.K. Rowling also copied the name of the Quidditch expert Kennyworth Whisper in the novel.
In the novel, Harry, the "catcher", can’t put it down. The history, rules and anecdotes of Quidditch are described in detail. Books with the same theme of Quidditch include The Broom Care Manual, The Miracle of Wigdown Tramps, He flies like a madman (the biography of "dangerous" Day Llewellyn) and so on.

The quidditch match scene in the movie is full of imaginative power. In Hollywood, where sports movies are popular, a Quidditch version may be a good choice.
These books are more magical than magical animals.
The monster book of monsters

This is a necessary textbook for the third-grade protection of magical biology class, which is replaced by Hagrid, but these books themselves are more fierce than the monsters in the books.
In order to show them, the display window of Lihen Bookstore was replaced by a big iron cage, which contained about 100 monster books of monsters. These books fought furiously together, biting and fighting militantly, and the broken pages flew everywhere.Insight Editions, a European and American publishing house, also announced the launch of a 1:1 scale prop replica of the book last year.

Neville longbottom was attacked by the "monster book" (why am I always injured)
Invisibility book of invisibility
Here is a picture of an "invisible book"
Nani, you didn’t see anything? That’s right. What the clerk of Lihan Bookstore regrets most is that he spent a huge sum of money to buy 200 "invisible books", because he never found them from the moment he signed for them.
Death omen: what should you do when you know the worst is coming? 》
Please resist the temptation of reading, because once you open it, the "death omen" will fill every corner of your life. Among Prisoners of Azkaban, Death Omen, which only happened once in a bookstore, became Harry’s nightmare. Is the dog on the cover the same one he saw in Magnolia Crescent Street?
Exaggeration and hypocrisy: a famous writer in Harry Potter

Harry Potter and gilderoy lockhart
As one of the main characters in The Chamber of Secrets, gilderoy lockhart is a new professor in defence against the dark arts and a world-famous writer. What’s more fatal is his handsome appearance and charming smile. Ron’s mother is his number one fan. Little did he know that all the stories in his autobiography were collected from other magicians, and he himself was just a cowardly, narcissistic and ignorant pseudo-hero.
In the end, Harry revealed his true colors. Unfortunately, he was hit by his own spell and had to spend the rest of his life in San Mungo.

Rita skeat, another famous writer, is even more notorious. She is a reporter for daily prophet. Under her "shorthand quill pen", there are no facts, only lies and revelations of bloggers’ eyes, which is simply the black sheep of journalists. She is also an illegal Ani maggs, who can become a beetle and capture all the news that can make her embellish.

Her "highest light" moment in the Harry Potter series was after Dumbledore’s death, and it took only four weeks to complete a 900-page biography — — Albus dumbledore’s Life and Lies claims that he knows Harry and Dumbledore best. Although these contents are dismissed as lies in the novel, they have aroused the infinite imagination of fans.
Her hair was made into delicate, stiff and weird curls, which matched her big chin face and looked particularly awkward. She is wearing a pair of glasses inlaid with jewels, and her thick fingers are holding an alligator handbag. Her nails are two inches long and painted red.
In Harry Potter, the writer has almost become synonymous with hypocrisy and exaggeration. It is said that this is Luo Yi’s satire and projection on the literary circle in reality. She has publicly stated that Lockhart does have a prototype in the real world.
The Holy Land of Books: Lihen Bookstore and Hogwarts Library
The famous Lihen Bookstore is located in diagon alley, next to Madam Malkin Robe Shop. Before school starts, every Hogwarts student will come to Lihan Bookstore to buy textbooks. The novel describes: "The bookshelves here are full of books, even reaching the ceiling, ranging from leather books as huge as paving slabs to small books with silver shells as small as stamps."

In the depths of the bookstore, a small table was divided to store books on prophecy and divination, among which "Death Prophecy" scared Harry. In The Chamber of Secrets, lucius malfoy mixed Tom Riddle’s diary into Ginny’s textbook at the signing ceremony of Lockhart in Lihan Bookstore.

The library of Hogwarts is one of the important scenes in the story. In retrospect, the protagonists are quite academic, and many difficult problems are solved by consulting materials in the library. In the first book, in order to find the information of the alchemist nicolas flamel, the three men searched almost all the books in the library.
There is also a special area full of temptations in the library — — "Forbidden Area", in The Sorcerer’s Stone, Harry, wearing an invisibility cloak, sneaked into the "Forbidden Area" but unfortunately opened a screaming book, which attracted Filch’s attention.
It is said that the prototype of Hogwarts, the Harry Potter series, was partly inspired by a bookstore in Portugal. When J·K· Rowling lived in Porto, he often went to Lero Bookstore near Lion Square in the old city to conceive and write. This Gothic bookstore has been on the list of "the most beautiful bookstores" in travel magazines for many times, and is known as the "Lihen Bookstore" in the Muggle world. From this point of view, the origin of Harry Potter series and books is doomed from the day of its birth.

In addition to the above, there are countless textbooks, history books, fairy tales, professional documents and even cookbooks and life skills guides mentioned in the Harry Potter series, covering all areas of the wizard world. The remarkable thing about "Aunt Luo" is that she can describe the details of the fictional world to the utmost amazement. It is the carving of these hundreds of books and other details that makes Harry Potter’s magical world more real, sensible and interesting.
If a 77-page "Fantastic Beasts and Where to Find Them" can be made into a five-part series, what a vast magical universe 303 books can extend and multiply.
For the complete list of Harry Potter, please say Accio’s words three times with me: "accio! Accio! Accio!”







CCTV News:On August 7th, the Central Radio and Television General Station’s "International Sharp Review" broadcast titled "The investigation of" TongRumen "is coming to an end. How much trouble will it be? The article was reprinted by many overseas media.
From 7 to 9 August, French LCF Radio facebook account, German-Chinese Report website, Spanish Radio International website, Italian Radio We website (facebook, twitter), Portugal Lisbon Rainbow FM website (facebook), Portugal Global Iberian client, Brazil Sao Paulo World Radio and Television website (facebook), Many overseas media, such as facebook, Turkish Economic Observation Network, Jordan Global Radio facebook account, Chinese PT portal, Chinese Headline APP, Portuguese New Newspaper APP(facebook, twitter), European Union Chinese website, Europe-China United Times website, Africa Times website, West Africa online website, Japanese Chinese business website, and Greek China website, have forwarded them one after another. From August 8 to 10, this article was also published and forwarded by Hong Kong Ta Kung Pao, wenhui network and Hong Kong Business Daily. The main reports are as follows:
US President Trump, who ruled the country by Twitter, once again pushed himself to the forefront with Twitter on the 5th, denouncing the report of "fake news" on his beloved eldest son Donald Trump Jr as "a complete fabrication", and revealed that in 2016, Trump Jr. met a Russian female lawyer at Trump Tower in new york, with the aim of obtaining information from his political opponents, which was "completely legal and a consistent practice in politics".
As early as more than a year ago, when The New York Times first disclosed the meeting, Trump Jr. made it clear that they were discussing a project on the adoption of Russian children that the US government had stopped. He also went to the closed-door hearing of Congress to ensure that Trump himself did not know about the meeting, and that the presidential campaign had nothing to do with Russia. However, a few months later, the media revealed that this statement was drafted by President Trump himself.
Now, 13 months after Trump Jr.’ s statement, President Trump actually admitted on Twitter that the meeting was to get the black materials of his opponent from Russian lawyers. People who are used to Trump’s reneging performance can’t help but be shocked when they see such a reversal! Ian Bremmer, chairman of Eurasia Group, the world’s largest political risk consulting company, concluded that either President Trump lied or the liar was Trump Jr.
The mainstream media in the United States and Europe have pointed out that the meeting two years ago happened to be an important link involved in the investigation of "TongRumen" conducted by Mueller, the special prosecutor of the US Department of Justice. With the approaching mid-term elections in the United States, the investigation of "TongRumen", which has been going on for more than a year, is drawing to a close. On the 5th, mainstream media in the United States, including Washington post, CNN and Associated Press, reported that the investigation of "TongRumen" is likely to harm people around President Trump, especially Trump Jr., the eldest son who planned and participated in the meeting.
Legal experts believe that Trump Jr.’ s contact with foreigners in order to obtain black materials from political opponents violates the relevant provisions of the US election law and may even be suspected of "conspiracy against the United States". At the beginning of this year, when Bannon, Trump’s strategist and former chief strategist of the White House, broke with Trump, he once said that the meeting was a treason. Nowadays, everyone has speculated whether such a heavy accusation has entered Muller’s "TongRumen" investigation list.
In fact, Mana Ford, another important figure in that meeting and former general manager of Trump’s campaign team, is now in deep jail because of many charges such as "conspiracy against the United States", and the case will be heard next month. At present, Manafort has been accused by the special prosecutor Mueller team for economic problems such as bank fraud and tax evasion, and the case has entered the trial stage. Although Mana Ford refused to plead guilty, Rick Gates, his former business partner and now a federal tainted witness, admitted to the jury on the 6th that he had helped Mana Ford commit crimes such as bank and securities fraud, and described the criminal process in detail. Earlier, Gates and Manafort were charged with money laundering and "conspiracy against the United States". He was dealt with separately because he all pleaded guilty and became a tainted witness.
Can Manafort continue to be hard-pressed and wait for Trump to exercise his presidential power in the future to give him Amnesty? Or will you plead guilty and become an important tainted witness of "TongRumen"? This is not only a drama that the media all over the world pay attention to, but also a trial that makes President Trump very worried.
Trump tweeted at the beginning of the trial that Mana Ford was wronged, saying that Mana Ford was once the right-hand man of former President Reagan and other Republican leaders, but now he was treated unfairly by the Mueller team, which was worse than that suffered by Alfonse Capone, the number one "public enemies" in the United States. He also questioned the evidence of communication with Russia and demanded that Attorney General sessions immediately terminate the investigation of "communication with Russia". Of course, the White House had to remedy afterwards that the president’s tweet was not giving orders, but expressing his views.

Trump’s aversion to the "TongRumen" investigation has a long history. Whenever it comes to the investigation of "TongRumen", he is always labeled as "witch hunting" and "fraud". According to American media statistics, in the first seven months of this year, he sent out 84 such labels.
At the same time, Michael Cohen, a former private lawyer who has handled all kinds of bad things and worries for Trump for many years, is now being investigated for being involved in bank and tax fraud activities, especially for possibly violating the relevant regulations of the election law. The US media disclosed that FBI agents had obtained a batch of audio clips in Cohen’s apartment, office and hotel room, among which Cohen secretly recorded a conversation with Trump, showing that they had discussed it with former Playboy magazine girl McDougall before the election, asking her to conceal her ulterior relationship with Trump. According to reports, Cohen also confirmed to the Muller investigation team that Trump met with Russian lawyers and got Trump’s approval in advance. This remark was immediately attacked by Trump’s current lawyer and former mayor of new york, Giuliani, calling Cohen a "pathological liar". Cohen, who used to talk about blocking bullets for Trump, has now turned against him. How much deadly black material is there in the conversation he secretly recorded?
As the investigation of "TongRumen" enters the final stage, President Trump, who is on vacation at the New Jersey Golf Course, is faced with a difficult choice: whether to take the initiative to accept the question of special prosecutor Muller or wait for Muller’s summons to answer the question? Will this duplicitous American president, who is good at picking things up, play another trick to divert public attention and cover up his weak life? Or, did Muller offer a fatal blow to Trump when former FBI Director Komi made a move against Hillary?

Zhongxin. com, Xi ‘an, April 25th: The satellite "housekeeper" casts a "monument" — — Visit China Xi ‘an Satellite TT&C Center
Author Zhang Chengwei Zhang Su
The ancient city of Xi ‘an is an international city where human history and modern science and technology complement each other. Xi ‘an Satellite TT&C Center, located here, is the earliest, largest and most functional spacecraft TT&C and management center in China, and has successfully completed hundreds of TT&C tasks for space launch.
The reporter learned that on June 23rd, 1967, China established the Satellite Ground Survey Department, which was the predecessor of Xi ‘an Satellite TT&C Center. In September 1975, the center was formally established.
The relevant person in charge said that the temporary command and control center that initially performed a single measurement and control task has developed into a modern space measurement and control center that integrates real-time measurement and control of spacecraft and long-term management of spacecraft in orbit. There is the only land-based space TT&C network in China, with TT&C sites spread all over five continents and 13 provinces and regions in China.
The first monument
China has no ready-made experience to learn from in building sophisticated satellite ground observation systems. The technicians of the satellite ground survey department started from scratch, worked hard, built the computer room, installed the antenna and laid the cable by themselves, debugged the equipment in the heat and cold, and wrote the program under the oil lamp in the humble room, which passed the difficult years in the history of measurement and control.
Under the auspices of Academician Chen Fangyun, the scientific and technical personnel gathered their wisdom to tackle key problems and worked out the measurement technical scheme of China’s first artificial satellite.
On April 24th, 1970, the "Dongfanghong-1" satellite flew to Tianyu, and China became the fifth country in the world to launch a domestic satellite with a homemade rocket after the Soviet Union, the United States, France and Japan. The launch measurement and control of the "Dongfanghong-1" satellite was a complete success. The center accurately predicted the time and position of the satellite flying over 244 cities in the world, and set up Chinese’s first "milestone" in the vast sky.
People follow the stars.
In the years after the successful launch of Dongfanghong-1 satellite, the United States and the Soviet Union launched several recoverable satellites. At that time, China had "two bombs and one satellite", its national strength gradually increased, and China astronauts were full of confidence.
On November 26th, 1975, China successfully launched its first recoverable satellite. The central activity monitoring and recovery unit "people move with the stars", using radio direction finder and other equipment to capture satellites returning at high speed independently, creating a successful achievement in satellite recovery.
Synchronous fixed point
In 1970s, the space powers accelerated the pace of space race. China executives pointed out: "China is a developing country. It will not participate in the space race in terms of space technology, and it should concentrate on urgently using practical satellites." China’s first applied satellite "Dongfanghong II" communication satellite came into being.
On April 8, 1984, China successfully launched the first communication satellite "Dongfanghong II". The center and the monitoring stations fought continuously, carefully monitored and controlled for 8 days and nights, and successfully positioned the satellite over the equator at 125 degrees east longitude and 36,000 kilometers. China became the fifth country in the world to launch a geostationary orbit satellite.
Spacecraft recovery
On September 21, 1992, China’s manned spaceflight project was launched. The center undertakes two major system tasks: measurement and control communication and landing site.
The landing site system is mainly responsible for the search and recovery of spacecraft return capsule and the search and rescue of astronauts. It is a complex system engineering with air-ground integration and multi-disciplinary cooperation. As the leading unit of the landing site system, the Center organized and coordinated more than 10 departments and units, including Aerospace Science and Technology Corporation, and set up an all-weather manned space search and rescue force with high mobility, forming a set of scientific program flow of recovery and measurement of the return capsule, high-precision impact prediction and astronaut search and rescue, and establishing a fast and safe search and rescue mode of "searching and rescue astronauts in the air and disposing the return capsule on the ground".
During the TT&C recovery mission of the Shenzhou-1 to Shenzhou-10 spacecraft, the center organized a search for rescue forces and repeated drills, creating a world space miracle that "rescuers arrived at the astronaut landing site in 30 seconds", the difference between the predicted landing point and the actual landing point was only 280 meters, and the orbital accuracy reached meters.
Multi-star management
In 1990s, in order to meet the needs of multi-satellite launching and parallel management, the Center put forward the optimal allocation strategy and algorithm of TT&C resources, and initially realized the separation of TT&C network management and spacecraft management. Since the beginning of this century, the number of spacecraft in orbit has increased, and the center has independently developed several sets of precision orbit control software, such as multi-satellite co-location control, constellation configuration control and multi-satellite formation flight. The accuracy of orbit calculation and control has always been at the leading domestic and international advanced levels.
In recent years, the center has vigorously promoted the automation construction of measurement and control system, and the space measurement and control network has gradually realized the automatic operation of "manned and unattended", which has a high level of visualization, informationization, automation and intelligence.
At present, there are more than 100 spacecraft in orbit managed by the center, and it has the ability to carry out orbit determination, state monitoring, attitude adjustment, orbit control and maintenance for 200 spacecraft in orbit at the same time. These in-orbit spacecraft have played an important role in information security in major events such as the Beijing Olympic Games and earthquake relief.
Deep space exploration
Driven by major aerospace projects such as lunar exploration, the center has overcome a series of key technologies such as long-distance tracking and measurement, and its measurement and control capability has achieved a major leap from earth orbit to lunar and deep space orbit spacecraft tracking and control.
During Chang ‘e-1’ s flight around the moon, the center made the communication distance of TT&C as far as 400,000 kilometers for the first time, knocking on the door of TT&C in deep space. In the "Chang ‘e II" mission, the center completed the whole tracking and measurement and control task from flying to circling the moon until the end of its life, and extended the distance record of measurement and control communication to 80 million kilometers.
In 2013, the center organized a tracking measurement test on the ESA Venus Express, and the measurement and control communication distance successfully exceeded 250 million kilometers. In the "Chang ‘e III" mission, the center adopted a series of advanced deep space measurement methods to ensure the accurate landing of the probe on the moon, and successfully carried out major space technology experiments such as lunar surface exploration, laying the foundation for the subsequent exploration of extremely distant stars such as Mars.
Looking back, the years are like songs; Looking to the future, the mission urges the levy. A new generation of space TT&C personnel will keep up with the forefront of world space science and technology development, blaze new trails and forge ahead hand in hand. (End)
