Although it is called “Russian teahouse”, the restaurant is actually an asset of a financial group in New York State and has no real connection with Russia, the report said. The story claimed to be run by Russian expatriates in 1927 is likely to be just a marketing gimmick, and all the bosses since then have been Americans. But that didn’t stop the protesters from boycotting - they opposed everything related to Russia, even if the name or dish had anything to do with “Russia”.

In the lower east side of New York, a restaurant called Veselka (Ukrainian meaning “Rainbow”) has a different atmosphere. It is overcrowded and there are long queues at the door. The owner of the Ukrainian restaurant said traffic had soared by 75% in just one week. The boss said he would donate the income from the sale of borscht to non-governmental organizations assisting Ukraine.

Until around 2035, a rotorcraft “Dragonfly” with the same volume as a car will take over the baton and land on Saturn’s largest moon Titan to carry out the first human exploration mission on the planet. In just one hour, the Dragonfly will fly farther than any previous ground rover on other planets. The multi rotor UAV will fly over the surface of Titan, then stay on the surface for a Titan day (equivalent to 16 Earth days), carry out various experiments, and then fly to the next destination. It will become the first spacecraft to fly around with all scientific instruments.

Compared with the difficult exploration process of curiosity rover, helicopters like wit may be able to explore Mars in a more relaxed way.

But for extraterrestrial flight, the biggest challenge (and possibly the biggest opportunity) is the Inferno hot Venus, because the Venus atmosphere is characterized by extreme high temperature, high pressure and acidity. So far, no lander can last more than 127 Hours on the surface of Venus.

Scientists plan to send two aircraft to Venus. One of them is a solar powered aircraft, which will pass through Venus’s relatively mild and harmless upper atmosphere; The other uses a flying wing design, which will fly through the harsh environment close to the surface. The technology of landing on Venus is very difficult to develop. Flying through the atmosphere may be the only alternative.

Teddy sanetos, a robotics expert from NASA’s air mobile team and leader of the smart team, is already working on the design of the next generation of Mars helicopters. “We all know how the Wright brothers achieved their first flight on earth, and now we will follow the same pattern on other planets.”

Like previous polar aerial exploration, engineers realized that aircraft would bring revolutionary changes to our exploration of outer planets. If atmospheric conditions are appropriate, Mars landers such as Viking and curiosity and orbiters such as Cassini will continue to play a key role in alien exploration, but now we have more choices. For example, maneuverable robotic airships, helicopters, drones, and even inflatable propeller aircraft (all proposed by NASA scientists) can collect high-quality data on a wide range of planetary surfaces in a short time, while avoiding all kinds of dangerous terrain. They can take close-up photos that can’t be taken by Rover or trackers, and they can also observe mission targets from different angles. These aircraft can reach places that Rovers cannot reach, such as mountains, peaks, and even the extremely inhospitable environment on the surface of Venus.

The dragonfly can be powered by a small reactor.

For engineers, the problem is that the environment of each planet has its own advantages, which imposes different restrictions on the applicable aircraft types, loads and functions, and engineers also face various technical limitations.

According to Wayne hull von Braun, the designer of Saturn 5 rocket, landing on Mars can be realized in the form of supersonic glider. Science fiction writer Philip Dick speculates that humans can colonize Mars with the help of helicopters. Engineers have carried out the conceptual design of the Mars spacecraft since the Viking landed on Mars in the 1970s, some of which are used in the predator UAV of the US military today.

The density of Martian atmosphere is only 1% of that of earth, so it is difficult for aircraft to generate lift. This means that the Martian helicopter must have a very light weight, but it must be able to carry lithium batteries, sensors and cameras, and have thermal insulation and insulation functions to spend the cold night on Mars. As long as you overcome these challenges and control the weight of the aircraft below 1.8kg, you can also build your own “wit”. Engineers have been studying Mars helicopters since the 1990s, but the technical conditions have not been met. However, since 2010, the research progress began to accelerate, and finally the technical demonstration was successfully realized.

Engineers actually also inspected fixed wing aircraft, but there is no airport on Mars, so helicopters are more suitable.

In the 1990s, the battery needed by “smart” has just been invented, and the potential of carbon fiber has not been explored. In addition, sensors, ultralight computers and flight algorithms are far from mature, and humans do not have the ability to build and operate such devices. Now, more than 20 years later, the situation has been very different. On today’s earth, drones are used not only to transport packages and vaccines, but also to investigate food crops and archaeological sites. These technologies all came together at the right time, and the “smart” was born.

The “smart” has completed several flight tests. This is mainly to prove that it can fly on Mars, and it has been successful 19 times. Every successful flight test provides a lot of valuable engineering data.

Titan’s situation is just the opposite of that of Mars, moving to the other extreme. Titan is the same size as the moon. Its surface is covered with a layer of ice shell. Below it is a huge ocean covering the whole planet. It is not only cold, but also “methane rain”. Some scientists have suggested that we can use ships to explore Titan’s surface, submarines to explore its underground sea, and airships to explore the atmosphere.

Titan’s environment is very special and suitable for exploration with aircraft heavier than air. Titan has less gravity and a dense atmosphere, which means that aircraft and helicopters can be larger, carry heavier loads and perform more functions than on Mars. Titan’s special environment means

Ms. Hui Limin, general manager of Fujian region of Baolong commercial group and general manager of Xiamen Baolong one city, Ms. Peng Xiaoying, general manager of Xiamen Baolong Art Center, illustrator halogen cat and audience friends attended the opening ceremony to jointly open an isolated dialogue between halogen cat and Xiamen. Hui Limin, Fujian regional general manager of Baolong commercial group and general manager of Xiamen Baolong one city, said that Xiamen Baolong one city has always been committed to taking “trend experience” as the keyword, echoing with business, paying attention to young people’s artistic creation and concentrating on “experiencing treasure space”. In the future, it will continue to introduce “artistic experience” to heal life with art and bring more innovative activities to the city.

The opening ceremony was specially held in the “Magic Garden” exhibition area, which was made interesting and dreamy, to lead the audience to explore the world in halogen cat painting by means of interactive experience. At the scene, halogen cat shared with you the feelings and feelings of returning to Xiamen to hold the exhibition, and expressed the hope to convey your current emotions and thoughts through the planning and bright colors of different regions.

It is reported that the “me and me - halogen cat solo painting exhibition” will continue from October 23, 2021 to January 22, 2022. The exhibition fully presents the works created by the illustrator halogen cat in recent years, from easel painting to sculpture and multimedia display. Through the colors of four seasons and five exhibition areas, it creates a deep sense of space and immersion experience, so as to immerse the public in the fantasy adventure of nature.

As an illustrator known to the public through the Internet, halogen cat’s works mostly focus on the natural daily life of the four seasons. “For me, painting is a window. Every time I open it, there are different scenery. This stems from the window view facing the sea I painted for myself in the niche of my room when I was a child. Now painting still takes me to see different scenery, traveling, memory and inner scenery. I record my feelings and record the dialogue between” me and me “again and again,” he said

At the solo exhibition held in Xiamen this time, halogen cat said that Xiamen is a city where he has lived for 8-9 years. After graduating from University, he came to this seaside city, which may be the guide of the “window” of his family, “Xiamen is my second hometown. Finding my own painting language and way to express myself here and returning to Xiamen to hold an exhibition is a dialogue between me and the first time I came to this city.”

At the same time, as a continuation of the “me and me - halogen cat personal painting exhibition”, the “Magic Garden - Baolong city” was exhibited in the public area of the atrium of Baolong city in Xiamen × “Halogen cat art exhibition” is also the first three-dimensional presentation of the artist’s series of works, in order to create an interesting and dreamy garden, lead the audience to explore the world in the painting in an interactive way, and bring a unique public art experience.

[about artists]

Cat, an illustrator, was born in Shouning, Fujian, China. His life back to the mountains and forests since childhood has made his works closely related to nature. After graduating from University, he came to Xiamen, where he found his own painting language. Vivid colors and casual strokes have become the symbolic features of his paintings. Through travel, he awakened the feelings of different seasons in his childhood mountain and forest life, including flowers in spring, leaves in summer, fallen leaves in autumn, snow in winter, dialogue with the four seasons, collected natural gifts, and recorded the richness and diversity of life in his works with a paintbrush.

He has published personal picture books “find the planet”, “Fox bu” and “four seasons in the suitcase”. He has drawn “education first” theme stamps for the United Nations post office, and has cooperated with famous brands such as Chanel, Louis Vuitton, apple and Google.

[about exhibition]

“Blue Garden”: blue is the most commonly used color of halogen cat. In his paintings, there will be a large number of blue, quiet dark blue, elegant pink blue, clear sky blue, bright cobalt blue… All kinds of blue gather to create his blue garden. He used blue to record the “Mayor garden”, recording the changes of the four seasons and his journey. The use of blue at different times and different scenes added a sense of tranquility and tranquility to his paintings.

“Me and myself”: “black dog” is a certain emotion of halogen cat, and it is also one of the images to express his current loneliness. In the works of this exhibition area, the audience will see a boy and a little black dog to express his loneliness: even if one person and one dog, it will not make people feel lonely, but can be cured by the painting and get comfort and happiness.

“Self portrait”: self portrait is a fixed theme in halogen cat’s paintings. He often draws a self portrait for himself, imagines his current appearance and records his current state. In these self portraits, we can see his state in different periods and environments, and his free strokes are restrained and conservative.

“Four seasons journey”: travel is a way for halogen cats to find painting inspiration, jump out of daily repetitive life and shuttle through different cities and seasons. Express your most sincere thoughts through the colors of four distinct seasons, immerse yourself in the fantasy adventure of nature, and enjoy the beauty of changes brought by the four seasons. It is not constant and changeable, but it is the expected rotation of the four seasons.

“Flowers”: living in the city, it is difficult to often feel the nature. Inserting a bunch of seasonal flowers at home is a way for halogen cat to “keep in touch with nature”. Plants have always been an important part of halogen cat’s paintings. He expresses his emotion and love for nature with a natural and sincere tone. Record the flowers in different seasons, which not only has the beauty of nature, but also has the interest of life.
