There is a new member in the world space race.

At 4pm local time on June 21st, South Korea’s self-developed launch vehicle "World" was launched from the Luo Lao Space Center in Gaoxing County, Jeollanam-do, and successfully separated from the satellite in the 700km synchronous orbit, successfully sending the satellite into the scheduled orbit.

This is the first time that a Korean-made rocket has completed a satellite launch mission, which also makes South Korea the seventh country in the world to put a satellite weighing more than 1 ton into orbit with a Chinese-made rocket, which is just as famous as Russia, the United States, France, China, Japan and India, and demonstrates its ability to launch spy satellites and build long-range missiles by itself.

The launch of the "World" also encountered various challenges. It was originally scheduled to be launched on June 15th, but it was forced to be postponed for one day due to windy weather. Then, due to abnormal data, the launch plan originally scheduled for June 16th was postponed again.

"World" is the first launch vehicle independently developed by South Korea. A total of 250 researchers participated in the research and development process, aiming at sending a 1.5-ton practical satellite into low earth orbit (600-800 km).

The whole project took about 12 years, with a total investment of nearly 2 trillion won (about 1.68 billion US dollars).

Nearly 30 years after South Korea launched its first rocket for scientific observation in June 1993, South Korean President Yin Xiyue celebrated: "Now the road to the universe has been opened from the land of South Korea, which is the product of difficult challenges in the past 30 years."

Former President Moon Jae in also wrote a post on Facebook praising KARI for "accomplishing great things" and said that the next goal is the moon.

South Korea officially joined the ranks of countries that have developed their own spontaneous rockets.

For decades, South Korea has always been obsessed with self-developed rockets.

They not only hope to be able to launch communications and other satellites in orbit by launching self-developed rockets, thus ranking among the elite national clubs in space, but also hope to better detect potential threats from other countries through satellite identification.

In 2013, after many delays and failures, South Korea put a satellite into orbit for the first time, mainly for research and development.

However, the two-stage rocket "Ronald" used for this mission was jointly built with Russia. This time, it cost nearly 1.9 trillion won (US$ 1.5 billion) to develop "World", which is called -II(Korea Space Launch Vehicle-II, and it is completely self-developed.

In October last year, in the first test shot of "World", the rocket sent a 1.5-ton simulated satellite into space 434 miles from the Earth. However, due to problems with the oxidizer tank, the satellite was burned earlier than planned and failed to stay in the scheduled orbit.

In this test launch, "World" not only carried a 1.3-ton simulation satellite, but also carried a 357-pound performance verification satellite. This is undoubtedly a major technological breakthrough for South Korea.

Ahn Sang-il, a senior researcher at Korea Aerospace Research Institute, said that this performance verification satellite will help scientists prepare to launch more satellites in the future, test antennas, generators and other satellite components, and transmit their trajectory data to Earth.

Attached to the performance verification satellite are four mini research satellites CubeSats, which were built by Korean University. These satellites weighing between 7 and 21 pounds will be released into orbit one by one from June 29th.

South Korea’s Ministry of Science and Technology said that only nine countries in the world have the ability to launch rockets by themselves, and only six of them can launch more than 1 metric ton of practical satellites; South Korea has mastered the relevant development and launch pad construction technology, becoming the seventh country with the ability to develop medium and large liquid rocket engines.

New research and development plans and launch plans are on the agenda.

The success of this launch plan has also made South Korea’s rocket launch plan more convincing.

It is understood that South Korea plans to conduct four test launches of the "World" system before 2027, and the latest one is tentatively scheduled for early next year. At the same time, South Korea is still developing a new rocket, which will be more than twice as powerful as the "World".

Not only that, South Korea also hopes to develop and use self-developed rockets to send unmanned spacecraft to the moon in the 1930s.

South Korea hopes to make full use of its rocket technology to build satellite-based navigation and next-generation communication networks. For example, it occupies a place in the world satellite launch market. At present, most rocket launches in the world are carried out by the United States, Russian, French, China, Japanese and Indian.

So far, South Korea has been relying on other countries to transport its satellites.

In July last year, South Korea used Musk SpaceX’s Falcon 9 rocket to put its first military communication satellite into orbit. According to the plan, they will launch a lunar orbiter this fall, also using Falcon 9 rocket.

The launch of the self-developed rocket is also a good thing for South Korea’s military. Without its own military satellite, South Korea has been using American satellites to guard against neighboring countries. Nowadays, self-developed rockets also mean that South Korea can put its own "clairvoyance" and "clairvoyance" in space.

South Korea and the dream of self-developed rockets

South Korea’s economic and technological strength, looking at the world, is still relatively powerful.

In 2020, South Korea’s GDP reached 1.6 trillion US dollars, higher than that of Russia. In terms of science and technology, the most powerful thing in South Korea is the semiconductor manufacturing industry. At present, in addition to TSMC, the other company in the world that can realize the mass production of CPU 5nm process is Samsung.

However, CPU and self-developed rocket are still two different things.

In the research and development of rockets, launch vehicles need to send satellites, manned spacecraft, interplanetary detectors and other spacecraft into space, generally with 2 ~ 4 levels. One of the most important components is the rocket engine. In the launching mission of the two-stage carrier rocket "Ronald", the first stage was made in Russia and the second stage was made in South Korea.

After the failure of the "World" mission last year, South Korea’s Minister of Science, Technology, Information and Communication, Lin Huishu, said that the main problem was the third-stage engine, which failed to reach the target of burning for 521 seconds, and stopped working early at 475 seconds, resulting in insufficient speed and failure to send the satellite into the established orbit. At present, it is speculated that it is not the cause of fuel shortage or rocket engine failure. It may be that there is a problem with the pressure system or parts fail to meet the expected performance, and it may also be that the valve is mistakenly started.

However, the success of the first and second stage separation, fairing throwing and three-stage engine ignition is the expected result, which shows that South Korea’s space technology has reached a certain level. The first-stage rocket is composed of four 75-ton thrust liquid engines, which can generate 300-ton thrust. It is reported that this technology is adopted for the first time by Korean domestic launch vehicles, and it is also one of the biggest difficulties in this research and development project.

Huang Zhicheng, an aerospace expert from China, said in an interview that the carrying capacity of "World" has surpassed that of the Long March-1 carrier rocket that launched China’s first artificial satellite Dongfanghong-1, but its overall performance is still inferior to that of the Long March-2 carrier rocket developed by China in the 1970s.

Failure is the past, and now the successful launch of the self-developed rocket is undoubtedly a tonic. It is estimated that from 2023 to 31, the South Korean government will invest 1 trillion 933 billion won (about 1.62 billion US dollars) in projects including launching large satellites in low orbit and independently launching lunar landing ships.

With South Korea officially joining the ranks of countries that have developed their own spontaneous rockets, the future space competition will become more and more fierce, and such a future is still worth looking forward to.

Original title: "twice postponed, South Korea launched its own research rocket and became the seventh satellite launcher in the world! Moon Jae in: The next goal is the moon.

Read the original text

In recent years, whenever the Mid-Autumn Festival approaches, "sky-high" moon cakes have become a "pain point" for consumers to shop. The relevant departments have begun to implement key supervision, but there are always merchants who "cleverly" evade the red line by playing the "edge ball". Yesterday (2nd), China Consumers Association also issued a consumer warning, saying that mooncake packaging is simple and appropriate.

Stealing and selling "high-priced moon cakes"
Merchants have three routines.

Routine 1: reselling and increasing prices

Recently, a brand announced that the Mid-Autumn Festival is approaching, and this year, two mooncake gift boxes, Yuhu Yingyue and Liuxin, were launched, with prices of 188 yuan/box and 318 yuan/box respectively, totaling about 100,000 boxes. At present, both mooncake gift boxes have been sold out, but many e-commerce sellers are still reselling at a higher price.

On an e-commerce platform, the price of "Yuhu Moon-welcoming Gift Box" sold by some merchants is more than 400 yuan, which is more than twice as expensive as the original price, even approaching the regulatory red line of "500 yuan". As for the "Flowing Moon Cake Gift Box", although many merchants show that they are out of stock, some merchants also show that they can consult customer service. In this regard, the customer service of the merchant was asked, and the customer service responded that the Liuxin moon cake gift box was still in stock, with a price of 636 yuan per box, and sent a link to the buyer. The content of the link shows that the price of the gift box of Liuxin Mooncake is 498 yuan, the price after the coupon is 486 yuan, and the courier fee is 150 yuan.

Routine 2: Hide keywords

Faced with the regulatory red line of "500 yuan", some online merchants also played a trick of hiding keywords. For example, in an ice cream flagship store, if you directly search for "moon cake", you can’t find more goods than 500 yuan, but if you search for "ice cream" or "gift box", there will be a variety of commodity exchange coupons, and some products are very similar in style to moon cakes.

In the commodity evaluation, some consumers exposed the Mid-Autumn Festival gift box redeemed by the exchange voucher, and the words "moon cake ice cream" were printed on the gift box.

Routine 3: Combination premium

In addition, under the banner of "Mid-Autumn Festival Gift Box", it is not uncommon to find mooncakes in commodities, and the price of these gift boxes often exceeds that of 500 yuan. In the flagship store of a red wine brand in Tmall, a Mid-Autumn Festival suit with a price of 1595 yuan, the picture shows that it contains two bottles of wine, two boxes of moon cakes and a multifunctional bottle opener. However, after inquiring in the flagship store, it was found that the total price of the two bottles of wine was only 710 yuan, which also meant that excluding the two bottles of wine, the value of other commodities such as moon cakes exceeded that of 800 yuan.

In another shop, there are as many as 24 kinds of mooncake gift boxes. The combination of goods available includes thermos cups, notebooks, scented candles, towels, honey, handmade soap, etc. Two ordinary mooncakes look like dispensable supporting roles.

"sky-high price" moon cakes are profitable.
Consumers are forced to pay the bill.

From the perspective of protecting consumers’ rights and interests, businesses increase profits by attracting purchases through over-packaging, and some consumers get a "sense of ceremony" by buying over-packaged products, which seems to be "one willing to fight and one willing to suffer", but in fact, consumers’ interests have been damaged and unnecessary expenses have been increased.

For consumers, the huge and complicated packaging box can only be thrown away, and only the products that are "trapped in it" have real use value. The cost of packaging is included in the price of goods, and it is finally passed on to consumers.

If all businesses make the trend of over-packaging worse and worse for the purpose of increasing profits, consumers will only be forced to accept the over-packaged products on the shelves over time, and eventually lose their right to choose.

Four departments jointly issued a regulatory announcement.
China Consumers Association warning: packaging should be moderate!

In June this year, the National Development and Reform Commission and other four departments jointly issued the Announcement on Curbing "Sky-high" moon cakes and promoting the healthy development of the industry, and put emphasis on the supervision of boxed moon cakes whose unit price exceeds that of 500 yuan.

Yesterday, China Consumers Association issued a consumer warning saying: Moon cake packaging is simple and appropriate.

The "slimming" of mooncake packaging is mainly reflected in four aspects:
First, limit the number of packaging layers, requiring that the number of packaging layers of moon cakes should not exceed three at most;
The second is to compress the packaging gap, reduce unnecessary gaps in the packaging box, and avoid "big cakes in the box are small";
The third is to reduce the packaging cost. For moon cakes with a sales price above 100 yuan, the proportion of packaging cost in the sales price will be reduced from 20% to 15%. For moon cakes with a sales price below 100 yuan, the proportion of packaging cost will remain unchanged at 20%. At the same time, it is required that precious metals and mahogany materials should not be used as packaging materials;
Fourth, strict mixing requirements, moon cakes should not be mixed with other products.

On the occasion of the Mid-Autumn Festival, China Consumers Association also encourages consumers to record the over-packaging and "sky-high" moon cakes that violate laws and regulations, standards, public order and good customs by hand, and report them to local market supervision departments and consumer associations.

　　Job-seeking students check the recruitment position information. China News Service reporter Chen Wei

　　As the development of Internet giants gradually entered the platform period, some fresh graduates who pursued long-term growth began to turn their attention to middle factories.

　　The so-called "middle factory" refers to companies that are not so large in scale but also have considerable popularity and reputation in the industry. Their products have also gained a place in the highly competitive market, which even makes some big manufacturers wary, and they are "potential stocks" in the industry.

　　Previously, many fresh graduates regarded the Chinese factory as a "spare tire": first, they took the offer from the Chinese factory as a guarantee, and then they broke the contract after getting the offer from the big factory. Nowadays, the trend has undergone subtle changes: an Internet industry headhunter revealed that many fresh graduates even gave up on their own initiative and went to work in a Chinese factory after receiving an offer from a big factory, and the "aura" of the big factory is gradually fading.

　　According to the data of BOSS Direct Employment Research Institute, in the spring of 2022, the recruitment scale of the Internet industry was at a low point since 2019, while the intensity of job hunting was higher than in previous years, and the competition among job seekers in operations and sales positions was obviously intensified. Compared with large factories, the middle factory, which is still expanding steadily, seems to be a better choice.

　　The reporter learned from an Internet recruitment platform that many non-head Internet companies that are on the rise have encountered a resume blowout this autumn.

　　Take Xiaohongshu, which is developing vigorously, as an example. By the end of September, the delivery volume of school recruitment resumes had more than tripled compared with last year. Among them, the number of students with high academic qualifications and prestigious schools has increased significantly. The number of resumes with doctoral degrees is five times that of last year, and the proportion of fresh graduates from C9 prestigious schools has also increased significantly. The number of students in Zhongqingbei (China University of Science and Technology, Tsinghua and Peking University) has increased by nearly 70%.

　　According to "LatePost", as of August 2022, the monthly active data of Xiaohongshu APP increased by 34% year-on-year, and it is also one of the few Internet platforms with the growth rate of users still exceeding 30%.

　　What has happened behind the wave of internet fresh people going to Chinese factories?

　　PK Factory in China: Pay and benefits are in line, and business is on the rise.

　　Job fair site.

　　Previously, the "halo" of big factories that attracted fresh graduates mainly came from their salary and welfare level. Now, many Chinese factories with good development momentum are gradually aligning with big factories.

　　Zhu Qing (pseudonym), a fresh student in 2022, worked as an intern in the technical department of Xiaohongshu for 8 months. She found that free meals and rental subsidies are also available here as standard. What impressed her most was that the company gave everyone a day off to go out and play on August 2 nd, and the company paid the bill. "There are more than 200 projects to choose from, which is eye-catching." Zhu Qing said, "This kind of atmosphere is not available in big factories. It is less brainwashed, feels more energetic, and what it does is not bad. Compared with this, it seems that big factories are not so ‘ Xiang ’ Yes. "

　　At the same time, some medium-sized factories in the rising business period not only increase the number of jobs, but also improve the quality requirements for talents. "The higher the business goes, the larger the number of users will be, and the complexity of technical problems will increase exponentially. They will want better talents in the market, and almost companies in a period of rapid development will face similar problems." A senior headhunter in charge of technical recruitment said.

　　In order to compete with big factories for talents, many Chinese factories have also offered competitive salaries. HR, a Chinese factory, told reporters that last year, the company began to provide great salary space for the recruitment of top technical fresh graduates, and gave an annual salary of about one million to the fresh graduates of some excellent algorithm positions in the first year. And in this year’s project, it is said that there is no limit on salary to grab the technical talents in the head.

　　In the eyes of professionals, another attraction of the Chinese factory comes from the relatively stable demand for talents.

　　"The talent strategy of the big manufacturers has been greatly expanded. Quickly spread out the business, blossom in many ways, and be more aggressive in recruitment. In the case of a bad environment, businesses with slow development or weak profit prospects will be decisively cut off to achieve cost reduction and efficiency improvement. For some Chinese factories, in the past few years, the products have maintained a relatively focused state, and the organization is relatively small and beautiful, and the demand for talents is relatively stable. " An Internet industry headhunter told reporters.

　　Don’t just want to be a "screw", pay more attention to the growth space.

　　Job seekers understand job requirements in the talent market.

　　When the middle factory gradually catches up with the big factory under the hard conditions of high salary and welfare, the children began to put forward higher expectations in personal growth after 00.

　　"I worked in startups and Internet companies during my internship, and I prefer the atmosphere of Chinese factories." Hua Juan (a pseudonym), a graduate of TOP4 Software College, told reporters. When he graduated, he won the offers from Ali and Tencent. However, considering the company atmosphere, personal growth, available space, future imagination and other factors, he finally did not accept these two offers, but went to bilibili. In Hanjuan’s view, bilibili has a good development momentum, and its seniors and sisters around it have a good reputation, and it belongs to a company whose business is still rising significantly.

　　Today’s Internet industry is no longer so "young", and many well-known companies have entered a mature stage. In the eyes of many younger job seekers, the businesses of big factories have already matured, and many jobs are actually more like assembly line operations, and most people are "screws". Compared with mechanized large factories, many medium-sized factories have a certain scale, but they have not fully developed and finalized, and their future development potential has more room for imagination.

　　"Under normal circumstances, an internship period of more than 6 months is just enough for me to follow a complete project. Compared with going to a big factory to make screws ‘ Gold plating ’ I prefer to choose a job with room for growth. " During the internship, Zhu Qing participated in the iteration of an important function, gained rich project experience, and successfully got the company’s retention offer. "Compared with big factories, Xiaohongshu has fewer employees and more opportunities to be independently responsible for business. More importantly, the company has not yet been listed, and there is more room for imagination. "

　　The reporter interviewed a number of graduates and found that compared with large factories, the middle factory has fewer organizational levels and is more flexible in talent appointment, which also means that fresh graduates can play their own value better.

　　Xiaoyuan (pseudonym) graduated from the State Key Laboratory of CAD&CG of Zhejiang University last year and joined Xiaohongshu. He was promoted within one year. At present, he has started to lead the team, set up a complete system of company search QP, and attacked key technologies.

　　Xiaoyuan’s experience made Bang Bang (a pseudonym), a 2023 graduate of a 985 university, quite envious: "Now it is difficult to get the bonus brought by organizational and business expansion when entering a large factory, and the pits are all occupied. Freshmen have to do the most basic things just one or two years ago, and it is increasingly difficult to get a special promotion. It is even more impossible to get the opportunity to lead a team just after graduation."

　　After giving up Ali’s offer and coming to bilibili, Xiao Zhu, another fresh student, also bluntly said that he had no regrets: "Although the team is small, the atmosphere is good. Everyone is technology-driven and does not engage in ‘ Horse racing ’ Mechanism. Compared with simply implementing the requirements of leaders, we will think about how to use technology to achieve business goals from the perspective of content business, and urge ourselves to establish more global thinking. "

　　He mentioned that his greatest achievement came from building a project from scratch. "I used to practice in a big factory, and I felt that I was working on a very mature and well-packaged system, like driving a car with automatic driving function, but I can participate here ‘ Make a car ’ This will test your ability and let yourself grow faster. "

　　Aken (pseudonym), who is in charge of quality assurance, jumped ship with his former boss to a medium-sized company on the rise after BAT encountered a promotion bottleneck. In his view, compared with large factories, there is enough time to grow, and the business in charge is more and more challenging. In his new position, he is responsible for planning the tool platform of the test process, and can be a project manager to promote the business from beginning to end, which he has never experienced before in a year and a half in a big factory.

　　With the change of job-hunting trend, the competition to enter the middle factory has become more intense. The scale of the middle factory company is small, and the number of interns and new job recruitment in each department is limited, so it is inevitable to "choose the best among the best".

　　An employee who enrolled in bilibili last year revealed that it was only after he joined the company that he learned that the admission ratio of his post reached an astonishing 3000: 1.

　　The reporter also learned that among the resumes obtained by Xiaohongshu in the 2023 school recruitment, the number of resumes with doctoral degrees is five times that of last year, and the proportion of fresh graduates from C9 prestigious schools has also greatly increased. The number of students from Zhongqingbei (China University of Science and Technology, Tsinghua and Peking University) has increased by nearly 70%.

　　Zhu Qing told reporters that the talent density in his company is very high. "Some groups even reach the level of holding top-level papers per person. As a school enrollment, they can get the guidance of industry experts and work with the best colleagues in the industry to solve business problems, which is also a spur to their own development."

　　Regarding career planning, Bangbang said frankly, "For fresh graduates, what kind of people can work with at the starting point of their careers is also an important factor affecting their future careers. Working with people with strong professional ability and excellent comprehensive quality, my growth will be faster. "

CCTV News:According to the data released by the National Bureau of Statistics today (April 11th), in the first quarter of this year, China’s consumer price rose by 1.3% year-on-year, while the ex-factory price of industrial producers decreased year-on-year. In March, China’s consumer price index (CPI) rose by 0.7% year-on-year, down from the previous month.

1— In March, on average, the national consumer price increased by 1.3% compared with the same period of last year, and the ex-factory price of industrial producers decreased by 1.6% compared with the same period of last year.

Guo Liyan, Director of Comprehensive Situation Research Office of China Macroeconomic Research Institute:Judging from the state of CPI operation in the first quarter of this year, food is a factor to stabilize CPI operation. For example, measures to stabilize the production of some fresh agricultural products and promote the convergence of production and marketing have been solidly implemented, and food has shown a trend of seasonal stability and decline. At the same time, the price of service also shows a moderate fluctuation trend, which is basically consistent with the current contact service industry and some aggregate consumption and stable upward trend. Prices continued to run smoothly in the first quarter, which also laid a solid foundation for the overall stability of prices throughout the year.

With the continuous recovery of production and life, the consumer market is well supplied. In March, China’s consumer price index (CPI) decreased month-on-month and increased year-on-year. From the ring comparison, food prices decreased by 1.4% due to factors such as warmer weather and increased fresh vegetables. Non-food prices fell by 0.2% from last month to be flat. In non-food products, due to the continuous recovery of travel demand, the prices of accommodation and air tickets increased year-on-year. From a year-on-year perspective, CPI rose by 0.7%, and the growth rate dropped by 0.3 percentage points from last month.

In March, affected by the accelerated recovery of the domestic economy and the price trend of some commodities in the international market, the national industrial producer price index (PPI) was flat month-on-month and decreased year-on-year. From the ring comparison, with the continuous improvement of domestic production and market demand, the prices of steel, cement and other industries have risen. Due to seasonal factors such as rising temperature, the demand for coal has decreased, and the prices of coal mining and washing industries have declined. In addition, the price of electronic equipment manufacturing such as computer communication has turned from a decline last month to an increase. From a year-on-year perspective, the PPI decreased year-on-year due to the higher comparative base of oil, coal, steel and other industries in the same period last year.
