The prosperity of the family is inseparable from the inheritance from generation to generation.

Trees have roots and water is active; People have ancestors and know their origins.

In China, there is an old saying that "three generations are not rich". The main meaning of this sentence is that countless famous families are finally lost in the long river of history, which makes people sigh. But this sentence is not accurate, and there are many families that have been passed down for hundreds of years, and the reason why these families can stand still lies mainly in the cultural heritage.

Any enterprise must have inheritance.

As a country famous for its craftsmanship, Japan has bred many craftsmen. Excellence and meticulousness have become synonymous with them, and their obsession with one thing has become spiritual wealth passed down from generation to generation. When it comes to crafts, many young people nowadays are unwilling to learn. After all, today’s craftsmen have been replaced by the so-called "online celebrity".

The prosperity of the family is inseparable from the inheritance from generation to generation.

Friends who have been to Japan know several places that must be punched in, such as Universal Studios Osaka, Tokyo Disneyland, street signs on Orange Street, and snow scenes in Otaru. These places can be regarded as scenic punch cards at most, and have nothing to do with the craftsman spirit. But some people go to Japan to explore the craftsman spirit that can still be found in today’s times. There are three gods in Japanese cuisine: "Sushi God" Jiro Kikuwabashi, "Tempura God" Saotome Zhezai and "Eel God" Kimben Kanejiro.

The prosperity of the family is inseparable from the inheritance from generation to generation.

Saotome, the "God of Tempura", is a philosopher. Everyone who has eaten it must know that the ingredients used in this shop are based on the local seasons, and each season has limited ingredients. It can be said that it is not easy to reserve a seat with the inheritance of the master. The diners who are lucky enough to eat in this store have extremely high requirements for the food itself, which happens to be a test of the master’s craftsmanship.

The prosperity of the family is inseparable from the inheritance from generation to generation.

Having said so much, what can be regarded as inheritance? As the saying goes, shine on you is better than Blue. After returning to China, Saotome Zhezai’s eldest disciple also opened a Tempura store, which inherited the master’s craftsmanship and can be described as passing on the culture of Tempura. Therefore, the craftsman spirit is not only reflected in craftsmanship, but the most important thing is the initial heart.

25 years of inheritance, contributing to 1.5 million users in China.

If Japan is a model of ingenuity, then Japanese car companies also have ingenuity, and so does Toyota. This brand has been doing one thing for 25 years, that is, developing dual-engine power.

The prosperity of the family is inseparable from the inheritance from generation to generation.

As a car company with early development and wide popularization of new energy technology, Toyota launched the world’s first mass-produced hybrid vehicle "PRIUS Prius" in 1997. In 2005, when the domestic new energy vehicle policy has not been introduced, subsidies have not been implemented, and the awareness of energy conservation and environmental protection of ordinary people has not yet awakened, Toyota has already rolled off the second-generation Prius equipped with THS system in Changchun, which shows its foresight and mobility. Up to now, Toyota has gone through four generations of development in 25 years, and the three technologies of Toyota’s twin engines have also gone through four generations of development. Compared with the original generation, the current hybrid system is smaller in size, stronger in performance, lower in cost, and also improves fuel economy. Although Toyota’s dual-engine technology is very mature, Toyota still focuses on the research and development of dual-engine technology, which coincides with the spirit of Japanese local craftsmen.

The prosperity of the family is inseparable from the inheritance from generation to generation.

At present, Toyota has 45 HEV products, and its cumulative sales in the world have exceeded 18 million. In China, nearly 7 out of every 10 hybrid cars are Toyota hybrids. The Toyota Twin Engine Family, composed of more than 10 models launched in China, meets the individual needs of different families living under the same roof for four generations. Its high-quality driving experience and fuel economy are enough for it to give full play to its comprehensive strength and become a well-deserved "C-hybrid" in the current wave of energy conservation and new energy.

The prosperity of the family is inseparable from the inheritance from generation to generation.

In the past few years, although there is no policy subsidy, the sales of hybrid vehicles in the domestic market have been leaping forward. Hybrid models have become the mainstream choice in the market because of their advantages of low fuel consumption, long battery life and low emissions. Up to now, the sales volume of Toyota Twin Engine in China has exceeded 1.5 million. With its advanced technology, maturity, reliability, fuel saving and environmental protection, Toyota Hybrid has made 1.5 million users a beneficiary, and users have gained word of mouth. At the same time, it also promoted the rapid development of hybrid technologies of other enterprises in the industry, including Honda and BYD. At the annual meeting of China Automotive Engineering Society in 2020, Li Jun, academician of China Academy of Engineering, chairman of China Automotive Engineering Society and professor of Tsinghua University, released the Technology Roadmap for Energy Saving and New Energy Vehicles 2.0 on behalf of China Automotive Engineering Society, which basically defined the development direction and goals in the next 15 years. It is clearly pointed out that by 2035, the automobile industry will realize electrification transformation, all traditional energy-powered passenger cars will be hybrid, and the sales of energy-saving vehicles and new energy vehicles will each account for 50%.

The prosperity of the family is inseparable from the inheritance from generation to generation.

It can be seen that in the 25-year accumulation, Toyota Shuangqing not only has a deep-rooted industry position and reputation, but also occupies a large part of the domestic family car market at present. It is said that "Toyota cars that can’t be broken", in fact, this view is not how strong Toyota cars are, but the failure rate is very low. As a consumable, it has been very successful to achieve the lowest failure rate within a limited range of use. Toyota twin-engine models are widely circulated in the industry for their high quality and durability in daily use. Japanese journalist Kiichiro Yokota once set a feat of driving the Prius across five continents. During the 12-year driving across five continents, he experienced the tests of various harsh environments such as the American jungle, the Sahara desert and the Qinghai-Tibet Plateau, and did not encounter any major faults and problems, which proved the superiority of Toyota’s hybrid technology in terms of power and reliability.

The prosperity of the family is inseparable from the inheritance from generation to generation.

Today’s Toyota, if the dual-engine technology is the main theme, it must be inseparable from the blessing of TNGA architecture. The TNGA architecture is not only another innovation of Toyota’s lean production, but also a perfect inheritance of Toyota’s philosophy of making "better cars" for consumers. Thanks to the blessing of TNGA architecture, the low center of gravity, 15% improvement in power performance, 20% improvement in fuel efficiency and optimization cost have been put into research and development again. The models under TNGA architecture have good maneuverability, and with the dual-engine technology, it can be said that Toyota’s new cars on sale will not be absent from the dual-engine technology, which is also the essence of the inheritance of Toyota’s entire brand.

The prosperity of the family is inseparable from the inheritance from generation to generation.

As the first choice for family cars, Toyota’s twin-engine models can meet any car demand of three generations, ranging from high-end Erffa twin-engine and Wilfa twin-engine to people-friendly Corolla twin-engine and Ralink twin-engine, and the price ranges from 150,000 to 800,000. Erffa and Highlander double engines can not only give high-quality travel experience, but also meet the large space demand for family cars and travel for home use. At the same time, their power, smoothness and fuel economy have become a new definition of higher driving experience. Corolla twin engines, Ralink twin engines, etc., meet the first choice of young consumers’ first car, with low cost, high endurance, high durability and comfort, and also allow young people to take into account the cost of car use and high-quality driving experience, killing two birds with one stone.

Write at the end:

The prosperity of the family is inseparable from the inheritance from generation to generation.

Home is a harbor for people to take shelter from the wind, and the family belongs to the roots of a big family. A dish, a cup of tea and a word can reflect the cultural heritage of a home. In fact, inheritance is not only about persistence and perseverance, but also about the concentration of one thing. After 25 years, Toyota has continuously improved the dual-engine technology, thus gaining the recognition of 1.5 million car owners in China. This persistence explains what the craftsman spirit is.

The film "Bei Er likes you" was released, and Jia Bing Liu Yan interpreted the love story.


1905 movie network news On April 14th, the film was released in China. As the only romantic comedy film in the same period, it was highly anticipated and attracted heated discussion among netizens. It is reported that the film is co-starred by director, starring, starring,,,,,, Sun Yue, Liu Tianzuo,, Zaza, Pan Youtong, Gao Dabo and Ma Dianbin, and tells the love story of Gong Bao (Jia Bing) and Fan Quinn (Ada), who meet each other when they are frustrated and heal each other in the fight. It not only retains the realistic and touching side of real love, but also adds more comedy elements, which makes people shine.

At the same time, "Bei Er Likes You" released a release poster, and Gong Bao looked lovingly at Fan Quinn, who bowed his head and smiled but his eyes were hazy. The ambiguous atmosphere between them spread in the streets in the evening, which made people look forward to it.

Jia Bing Liu Yan interprets the real love story with laughter and tears, full of emotion and moving.

The poster chose a picture of two people drinking and talking in the street in the evening. The sky was set off in blue by neon lights, and the little lights in the foreground set off the overall artistic conception in a hazy poetic way. Gong Bao smiled at his beloved girl, and without the help of words, love overflowed from his eyes; Fan Kuin bowed his head and smiled, but his eyes were wetted by tears, and the frozen picture will also express the complicated emotions incisively and vividly at this moment.

Different from the narrative methods of love-hate entanglements in previous love movies, the movie "Bei Er Likes You" focuses on more pyrotechnic love stories, which enlarges the happy daily life in love and adds more realistic descriptions. Gong Bao and Fan Quinn treat each other from beginning to end, which is the only thing for each other in this life. Being close to each other in the daily life of fighting and chatting has become an inseparable part of life. In the face of realistic difficulties, the two support each other and become each other’s most solid backing. Just like ordinary couples in reality, they can laugh when they cry with their lover’s firm company.

 

Father-daughter affection has become a highlight of the film, attracting countless audiences to tears.

In the movie "Bei Er likes you", not only love is involved, but also the description of friendship and affection makes each character more three-dimensional and the whole story more full and realistic. Among them, the contradiction between Van Queen (Ada) and his father (Yang Xinming) has become a part that resonates with many people except the love line. Fan Quinn and his father have their own obstinacy. His father kept his lifelong career and refused to bow down. Fan Quinn tried to pursue distant dreams but ignored family ties. Because of Gong Bao’s unexpected appearance, they learned each other’s minds in repeated quarrels, and then chose to resolve conflicts in a place symbolizing new life, which was really touching.

Some netizens said: "In addition to love poking me, the family line in the film is unexpectedly beautiful. The old people stick to their own ideas, but their children want them to keep up with the tide of the times. Every time they play against each other, it is like a warning to me, which is the epitome of real life." There are also many netizens who burst into tears after seeing the scenes of father and daughter, which is very moving.


Foreign Ministry spokesperson: The cause and effect of the current tension in the Taiwan Strait are clear, and the right and wrong are clear at a glance.

  Xinhua News Agency, Beijing, August 5 (Reporter Feng Xinran) Foreign Ministry spokeswoman Hua Chunying pointed out on August 5 that the cause and effect of the current tension in the Taiwan Strait are clear, and the right and wrong are clear at a glance. The US side is an active provocateur and a crisis maker. China’s counter-measures are a necessary warning to provocateurs, a legitimate defense of national sovereignty and security, and a firm safeguard of regional peace and stability and the basic norms of international law and international relations.

  Hua Chunying said at a regular press conference that the current situation was entirely caused by Pelosi and American politicians. The essence of the Taiwan Province issue is not a so-called democracy issue, but a major principle issue concerning China’s sovereignty and territorial integrity. "The United States should put itself in the other’s shoes. If a state in the United States tries to split from the United States and establish a country separately, and another country provides it with weapons and political support, can the American government and people allow it?"

  Hua Chunying emphasized that Pelosi’s flight to Taiwan seriously violated the one-China principle, trampled on the basic norms of international relations and seriously damaged China’s sovereignty and territorial integrity. China has made the utmost diplomatic efforts. Various channels have repeatedly warned the US side of the seriousness and harmfulness of Pelosi’s flight to Taiwan, clearly pointing out that China will not sit idly by and give any space to the "Taiwan independence" separatist forces, and the US side will be responsible for all the consequences arising therefrom. All parties in the international community have also issued early warnings, pointing out that Pelosi’s visit to Taiwan is a completely unnecessary malicious provocation and will trigger a serious crisis. Unfortunately, the United States turned a deaf ear to this and went its own way.

  "The U.S. malicious provocation first, China’s legitimate defense behind. China’s counter-measures are necessary warnings to provocateurs and legitimate defense of national sovereignty and security. " She said, "Now the United States and some of its followers have jumped out and accused China of overreacting. If they really care about regional peace and stability, why didn’t they stand up earlier and discourage Pelosi from going to Taiwan? ! The countermeasures taken by China are justified and necessary, and not excessive. As the perpetrator and initiator of this crisis, the United States should and must bear full responsibility for this. "

  Hua Chunying said that China’s relevant measures also firmly safeguard regional peace and stability and the basic norms of international law and international relations. "Today in the 21st century, we must not allow the United States to pretend to be a world policeman and an international judge, and continue to regard other sovereign countries as Freud who can be killed at will." If China is indifferent to the US’s aggressive actions of interfering in internal affairs and damaging China’s sovereignty, and does not resolutely resist the US’s reckless and irresponsible actions, the purposes and principles of the UN Charter, such as respecting sovereignty and territorial integrity, and the basic norms of international relations will become a dead letter, and developing countries, which account for more than 80% of the world’s population, may become the next target at any time.

  "Because of this, more than 160 countries have recently issued just voices, reaffirming their adherence to the one-China policy and supporting China in resolutely safeguarding its sovereignty and territorial integrity. This is a major struggle between hegemony and anti-hegemony, interference and anti-interference, separatism and anti-separatism. " She said.

  Hua Chunying said that China was invaded by foreign powers in history, but China is no longer China 120 years ago. The people of China will never allow foreign forces to bully, oppress and enslave them. Anyone who wants to do this will surely face the wall of steel built by more than 1.4 billion people in China. The position of the government of China and the people of China on the Taiwan Province issue is consistent, and it is the firm will of more than 1.4 billion China people to resolutely safeguard China’s national sovereignty and territorial integrity.

  "I hope the United States and those so-called ‘ Democracy ’ The country’s followers clearly recognize this and attach importance to and respect the core interests and firm will of the people of China, who account for one-fifth of the human population. " She said.

Up to 3,000 yuan subsidy Chongqing introduced the subsidy policy for replacement and renewal of new energy vehicles in 2024.

People’s Daily Online, Chongqing, May 21 (Reporter Feng Wenyan) Recently, the Chongqing Municipal Commission of Commerce and other four departments jointly formulated and issued the Notice on Implementing the Replacement Subsidy for New Energy Vehicles, while implementing the national subsidy policy for replacing old vehicles with new ones (that is, scrapping and updating), supporting the implementation of Chongqing’s subsidy policy for automobile replacement and updating, and taking various measures to effectively release the potential of the automobile consumption market.

"In recent years, with the continuous increase of car ownership in the city, car consumption has entered an era of equal emphasis on increment and stock from the era of incremental market, and there is huge market space for car scrapping and replacement." The relevant person in charge of the Chongqing Municipal Commission of Commerce said that from January to April 2024, the sales of generalized passenger cars in the city were 139,000, up 7.0% year-on-year, of which 58,000 were new energy vehicles, up 35.6% year-on-year, and the market penetration rate reached 41.5%.

According to reports, the application time of this subsidy is from 0: 00 on May 21, 2024 to 24: 00 on October 31, 2024, and the subsidy funds are used up or the policy expires.

The subsidy object must meet the following five conditions at the same time: first, individual consumers; Second, from 0: 00 on May 21, 2024 to 24: 00 on October 31, 2024, I sold and transferred the old passenger cars (including new energy vehicles and fuel vehicles) registered in my name on or before May 20, 2024 nationwide, and purchased new energy passenger cars from automobile sales enterprises within the jurisdiction of Chongqing; The third is to fulfill the obligation of tax declaration for new car purchases and improve the procedures for household registration in accordance with the regulations throughout the country within the applicable time of subsidies; Fourth, the individual consumer who sells used cars must be the same person as the individual consumer who buys new cars; Fifth, according to the procedure, the declaration was successfully made and the examination requirements were complete and true.

Those who meet the subsidy conditions shall voluntarily declare according to the relevant requirements of the subsidy application materials and the fixed reporting channels, and after passing the examination according to the procedures, each car with a bare car price of less than 200,000 yuan (referring to the total amount of price and tax on the Uniform Invoice for Motor Vehicle Sales, the same below) will be given a subsidy of 2,000 yuan, and each car with a bare car price of 200,000 yuan or more will be given a subsidy of 3,000 yuan, which will be paid in cash to the bank card of the object who meets the subsidy conditions. The fund scale of this round of subsidy policy is 20 million yuan, which will be paid according to the principle of "purchase first and make up first", and the policy will stop when the funds are used up or the declaration expires.

According to the relevant person in charge of Chongqing Municipal Commission of Commerce, those who meet the subsidy conditions should enter the online declaration system of Chongqing’s automobile consumption subsidy policy from 0: 00 on May 21, 2024 to 24: 00 on November 30, 2024 by paying attention to "Chongqing Municipal Commission of Commerce" WeChat WeChat official account and "Aishang Chongqing" WeChat WeChat official account or scanning "QR code of Chongqing’s automobile replacement subsidy declaration system". For those applicants who meet the subsidy conditions, the subsidy funds will be distributed within 15 working days after the online examination and approval.

At the same time, in order to effectively play the role of policy instigation and amplify the effect of subsidy policy, the Municipal Commission of Commerce will also widely mobilize automobile dealers, automobile manufacturers, banking and financial institutions, platform enterprises and districts and counties to follow up and introduce supporting measures to jointly promote automobile consumption.

Welcome the first space day: we will launch a "laboratory" into space.

The State Council recently approved that April 24th will be designated as "China Aerospace Day" from 2016.

The establishment of the first space day in China is of far-reaching significance. This year, there will be a series of "big moves" in China’s space field, especially in the second half of 2016, China will soon launch Sky-2 Space Laboratory to carry out space science and application experiments in the fields of Earth observation and space earth system science, new space application technology, space technology and space medicine, and build China’s first real space laboratory.

Then the question is coming. What is the origin of Tiangong-2? Why should we move the laboratory into space? What magical scientific experiments will be carried out in this mysterious laboratory?

Space laboratory VS space station

Different from ordinary satellites, Tiangong-2 is a space laboratory undertaking scientific experiments. So, what is a space laboratory?

Space laboratory, as its name implies, is a laboratory built in space.

This special laboratory consists of unmanned space laboratory and manned spaceship. It is necessary to launch an unmanned space laboratory first, and then send a manned spacecraft into space with a launch vehicle to rendezvous and dock with the laboratory in orbit. Next, the astronauts will enter the space laboratory from the spaceship, carry out their work, and then return to Earth by spaceship after completing their work.

Following this line of thought, the first step to build a space laboratory in China is to launch Tiangong-2, and then launch the Long March 7/5 carrier rocket to send the Shenzhou 11 manned spacecraft into space and dock with Tiangong-2, thus completing the construction of the space laboratory.

Figure 1 Model of Tiangong-2 Space Laboratory

So, what’s the difference between a space laboratory and a space station? Does it mean that China will soon have a space station after the launch of Tiangong-2?

Of course, it’s not that simple: the space station refers to a manned spacecraft that can be visited by many astronauts for long-term work and living. Well-known space stations include the salute series space station launched and built by the former Soviet Union (it is said that the domineering elder brother of the former Soviet Union built the first space station in human history in a rage because the United States planted the national flag on the moon before the former Soviet Union) and the Mir space station, and the international space station jointly built by the United States, Russia, Japan, Canada, Brazil and the European Space Agency (ESA) (indeed, "many hands make light work", which is the largest space station ever owned by mankind.

The biggest feature of the space station is its huge scale and volume, and its long time in orbit. For example, the famous International Space Station has been working for human beings for 16 years.

Figure 2 International Space Station

The space laboratory is more like the predecessor of the space station, which is an experimental spacecraft for the development of the space station and the transition from manned spacecraft to manned space infrastructure. In other words, the space laboratory is a preparation for building a more complex space station.

Both theoretical research and practical experience show that launching a space laboratory is an important prerequisite and technical guarantee for building a space station. The launch of the space laboratory can test the key technologies of the space station, gain experience, reduce risks and lay the foundation for the construction of the space station. Therefore, the imminent launch of Tiangong-2 does not mean that China will soon have its own space station, but only that it will lay a good foundation for the construction of the space station, and the space laboratory is not the same as the space station.

The space experiment of "unclear consciousness" on Tiangong-2

As the first real space laboratory in China, Tiangong-2 has carried an unprecedented 14 experimental projects, and it will soon become the "busiest" space laboratory in China.

Being able to get the "admission ticket" to board Tiangong-2, these experiments undoubtedly belong to the most advanced exploration fields in the world today. For example, the Institute of Mechanics of Chinese Academy of Sciences undertook the research project of "Thermocapillary Convection". The project will build two experimental platforms, space and ground, for experimental research. The chief designer of Tiangong-2 Thermal Capillary Convection Space Experimental Project and researcher Kang Qi of Institute of Mechanics, Chinese Academy of Sciences explained the project.

Fig. 3 Chief designer of Tiangong-2 thermal capillary convection space experiment project and researcher Kang Qi of Institute of Mechanics, Chinese Academy of Sciences.

First of all, what is the phenomenon of thermocapillary convection?

Researcher Kang Qi explained that thermal capillary convection is a kind of thermal convection phenomenon related to fluid surface or interface. As we all know, there is interaction force between molecules on the interface of fluid, that is, surface tension, and with the change of temperature, the surface tension will change accordingly. Therefore, when the temperature distribution on the fluid interface is uneven, the surface tension will be different at different positions, thus forming a phenomenon that drives the fluid flow, that is, thermal capillary convection. Surface crystal growth is affected by buoyancy convection, resulting in defects, while space crystal growth is affected by thermal capillary convection, and defects also occur from time to time. It is of great significance to study the problem of thermocapillary convection in practical industrial production for improving the quality of crystalline crystals. For example, if we want to produce high-quality semiconductor materials, we must scientifically control the influence of buoyancy convection and thermocapillary convection on monocrystalline silicon during crystal growth.

Fig. 4 schematic diagram of thermal capillary convection phenomenon

Since the phenomenon of thermocapillary convection exists widely in actual production and life, why do we have to go to Wan Li to study it in space?

The answer is due to the unique microgravity environment in space.

As we all know, objects in space are hardly affected by gravity, and microgravity environment refers to the environmental conditions where gravity is close to zero. Under this condition, buoyancy convection will be greatly reduced, and the obstacles that affect our study of thermocapillary convection will be infinitely reduced, which means that the real process of thermocapillary convection can be truly displayed, which is conducive to scientists’ deeper analysis and exploration.

Therefore, it is not a waste of taxpayers’ money for Wan Li to send the experimental project into space not far away, but to see the "true face" of the heat-clearing capillary convection phenomenon, and scientists are really struggling.

Fig. 5 Some experimental devices of Tiangong No.2 liquid bridge thermal capillary convection space experiment project.

Why do you do the same experiment in the sky and underground?

As mentioned earlier, in addition to the experimental device attached to Tiangong-2, the same experimental device was set in advance on the ground. What is the reason for doing the same experiment twice? Duan Li, deputy director designer of Tiangong-2 thermal capillary convection space experiment project and researcher of Institute of Mechanics, Chinese Academy of Sciences, answered this question.

Researcher Duan Li explained that because there are few opportunities and high costs for space experiments, and the relationship between thermocapillary convection and its influencing factors can not be accurately described by simple formulas, it is necessary to conduct ground experiments to provide a scientific and reasonable reference range for the smooth progress of space experiments. In this experiment, the experimental equipment used in the space laboratory and the ground laboratory is the same, that is, an experimental instrument called "liquid bridge".

Fig. 6 schematic diagram of liquid bridge experimental device

The above picture is a brief sketch of the liquid bridge model. The liquid is located between the upper and lower bridge columns, and the temperature difference between the upper and lower bridge columns is controlled, so that thermal capillary convection is formed in the liquid.

However, due to the existence of gravity, it is impossible to establish a large-scale liquid bridge model in ground experiments. Usually, a small-scale (4-5mm diameter) liquid bridge is used, but it is still affected by buoyancy convection, which is why scientists want to send it into space for research.

Ground experiments provide data reference for space experiments, and space experiments complete the range that ground experiments can’t achieve. The two complement each other and are indispensable.

In 2011, the successful launch of Tiangong-1 made hundreds of millions of Chinese sons and daughters excited. Now Tiangong-1 "retired" and Tiangong-2 will "relay on duty", which will usher in a new era of space application technology in China.

2016 is the first year of China’s 13th Five-Year Plan. Besides Tiangong-2, Long March 7/5 rocket and Tianzhou-1 cargo spacecraft will be launched one after another this year. On this basis, China will build a permanent space station around 2020, and it will be fully operational in 2022. With the increasing strength of science and technology, China is making a magnificent turn from a "big" country to a "strong" country in space. Let’s look forward to it.
