“We cannot risk the lives (of the astronauts) … The structures and metals on the ISS (are) getting old, possibly leading to irreversible consequences,” Borisov said. Disaster is waiting to happen. Borisov announced that Russia would withdraw from the ISS by 2025. However, he later delayed the time because the country needed to check the technique, decide and inform partners of the plan to build a new space station.

The Russian Space Agency (Roscosmos) also confirmed that it is developing a successor space station for Salyut and Mir, two space stations launched into low-Earth orbit by Russia in the 1970s and 1980s. know that agreements with international partners related to ISS will expire in 2024. Share on television, Borisov said that the new Russian space station will orbit the Earth at high latitudes, helping to see the polar regions better. He leaves open the possibility of inviting foreign countries to participate in the construction of the space station. In the video posted to the Internet, Dmitry Rogozin, the director of Roscosmos, said that the first module of the space station is under development, possibly in 2025. Interfax Modules assembled by Energia cost about US $ 5 billion. Still, the prospect of a complete Russian space station is far from over. Andrey Ionin, a member of the Russian Space Academy, said that the new space station would be “a step backwards”. “ISS’s greatest achievement is not technology, but international cooperation,” said Ionin. Before building the new space station, Roscosmos still has to bring the Nauka scientific module to the ISS at the end of the year. Rogozin said Russia will not withdraw from the ISS until the completion of the new space station. However, the announcement from Deputy Prime Minister Borisov will put great pressure on the US Aerospace Agency (NASA) and its partners. Russia believes the ISS is degrading. Photo: Roscosmos. Space stations over 20 years old have regularly recorded incidents in recent times. In March, Russian astronauts patched a gas leak on the ISS that has existed since 2020. This is not the first time Russia has complained about the ISS. Speaking at the Russian Academy of Sciences in October 2020, Vladimir Solovyov, who is in charge of Russian flights at the ISS, thinks the space station will deteriorate rapidly in the next five years, advising the country to prioritize building. new universe. “The ISS partners will have difficulty maintaining the space station without Russia,” said Vitaly Egorov, the space industry watcher. Science . The magazine says SpaceX’s astronaut transportation services can fill the void left by Russia. Two astronauts installed the support frame outside the ISS station Two NASA astronauts step outside of the International Space Station (ISS) to install supports for new solar panels.

The Grand Canyon of Northern Zhejiang, which began in the early summer and flourished in the Han Dynasty, not only has a very rich cultural landscape, but also a splendid Confucian and Buddhist cultural landscape. There are nearly 100 majestic peaks in its territory, which are more than a hundred kilometers above, so it was originally called the Seventy-two Peak of Dahan. As early as the end of the 22nd century BC, it was recorded that Dayu came to the Seventy-two Peak and planted Taihu Liumu at the source of Lake Tai. As a result, the willow trees on the peaks of the valley became shaded, so that the floods no longer flooded. In 117 BC (the fifth year of Emperor Wu of the Han Dynasty), Emperor Wu of the Han Dynasty led an army to attack South Vietnam. Seeing that the valleys and mountains were connected, the terrain was dangerous, and the defense was invincible, so he set up camp on the spot, and the northern Zhejiang Grand Canyon was also named after this. Because of the historical heritage of Buddhism and Confucianism, the strong Buddhist cultural atmosphere also puts an ancient and mysterious atmosphere on the canyon. There are Honglin Temple, Dushan Temple, Xishan Temple and Xujia’an in the mountains, which are called the “One Leaf of Buddhism” in the south of the Yangtze River. The Honglin Temple was built in the Sui and Tang Dynasties and has a history of more than 1,000 years. The stone sculptures of Maitreya Peak, Tathagata Peak, and Guanyin Peak are fused in the mountains and rivers, and the flowers and the grass reveal the tranquility of Zen. Today, the incense of Honglin Temple is still vigorous, and the incense lingering around the tip of the nose can quite feel the meaning of “no peaks are not strange, no stones are not steep, and no temples are not ancient”. The North Zhejiang Grand Canyon is located at the border of Tianhuangping in the southern boundary of Anji County and the source of Taihu Lake in the northern boundary of Lin’an City. The entire scenic area is built on the mountain, with a total area of ​​38 square kilometers, consisting of Dahanling, Dongling, Shiling and Longxu Mountains. , The five scenic spots of high mountain farm holiday. Walk along the stone steps along the trail of the North Zhejiang Grand Canyon for about 40 minutes, and you can see the first waterfall of the Huangpu River Source at an altitude of 680 meters. There are mountains and water. There are many currents in the canyon, many large and small. waterfall. The first waterfall at the source of the Huangpu River is the largest waterfall in the canyon. The waterfall has a drop of 30 meters and a width of up to 5 meters. It is controlled by the north-south fault and forms a steep ridge perpendicular to the direction of the canyon. The crystal clear ice waterfall arbitrarily The rocks fell into a waterfall. The source of the Huangpu River, the mother river of Shanghai, is here, so it is also called the “small source of the Huangpu River.” There is also a “first-line waterfall” with a trickle that is eye-catching. The water flow is not large, but it flows all the year round. It is said that the flow has not stopped even in the dry season. The canyon is lined with dense forests, accompanied by mountains and streams all the way. There are many scenic spots in the scenic area of ​​the North Zhejiang Grand Canyon, including five mountain terraces, fifty-eight streams, and ninety-eight waterfalls. There are a total of 203 large and small scenic spots. The beautiful natural scenery also contains rich cultural landscapes. The Confucian and Buddhist cultural landscapes praised by scholars and scholars in the past dynasties are the spiritual charm of the Zhejiang Grand Canyon, and the original natural landscape is a natural portrayal of the Zhejiang Grand Canyon. Geographical location The Great Canyon of Northern Zhejiang on the 30th parallel of the latitude of the world’s geographic location is also a “mystery”. Its “fascinating place” requires us to be on the scene to explore!

The North Zhejiang Grand Canyon is located about 35 kilometers southwest of Anji County. Its geographic location is on the 30-degree north latitude line known as the “world geography mystery”, with many amazing natural wonders. The North Zhejiang Grand Canyon is now a national AAAA-level tourist attraction, and it is a good place for leisure vacations in the mountains, sightseeing, summer summer and mountain recreation projects, attracting many tourists. The North Zhejiang Grand Canyon has a reputation as “Zhejiang’s Qinghai-Tibet Plateau”. Of course, this is inseparable from the natural landscape here. There are hundreds of peaks above 1,000 meters, and there are many strange peaks and rocks in the Grand Canyon. Bitan Waterfall is densely covered with green pines. If it encounters a rainy day, the clouds and mist in the mountains will add a lot of mystery to the Grand Canyon of Northern Zhejiang. As early as the Emperor Wu of the Han Dynasty, Emperor Wu of the Han Dynasty came here when he led the war. Seeing that the mountains are connected, the mountains are majestic, and the scenery is beautiful. It is an excellent place that is easy to defend and difficult to attack. There are many mysterious stories, and now many scenic spots in the Grand Canyon are also related to it. There is a scenic spot in the mountains called “Strange Stone Ditch”. There are many secluded pools here, and it is known as “Nine Bays and Eighteen Pools”. The stream in the secluded pool is crystal clear, and the scenery is quiet and beautiful. While feeling the coolness brought by nature, it is also a good place to take portraits. You can take pictures with a quiet atmosphere. Now is the season when azaleas bloom. There are many flowers and trees here. The most distinctive one is “wild azaleas”. The azaleas are also called azaleas. The bright red azaleas in full swing look particularly beautiful. , Its brilliance seems to have reflected all the mountains in red, hence the name. As a scenic spot dominated by natural landscapes and amusement experiences, complemented by cultural landscapes, there are a lot of small scenic spots in the mountains, which can be described as one step by step, and step by step. Now that the weather is getting hotter and hotter, why not look for a place to escape the summer heat! There are also several internet celebrity check-in points in the mountains. One of them is the “one-line waterfall”. I saw a silver waterfall flying down. The white water, the blue mountains and the green jungle are in harmony with each other, although the scenery is not very spectacular. But it is the unique beauty of Jiangnan, which attracts many tourists to take pictures here. The mountain streams are gurgling, and the clear springs are naturally indispensable. You can see many places along the way. According to legend, the Emperor Wu of the Han Dynasty had a psychic BMW. When he walked to Majiangang, the soldiers he led were very thirsty. However, it was difficult to find the source of water because of the high mountains and dense forests, and the BMW used horse hooves. There was a stream of clear springs that made people wonder. There are also many temples hidden in the mountains, adding a lot of humanities to this beautiful place. The temple in front of you is a temple that combines Buddhism and Taoism. Its history can be traced back to the Han Dynasty. It has a history of more than 2,000 years. Most people who visit will choose to go in and pray for blessings. For me, I feel that the essence of the North Zhejiang Grand Canyon lies in the “First Waterfall of Huangpu River Source”, which is located at the end of the whole journey. Before entering the waterfall, I have heard the sound of the waterfall torrents from a distance. Thanks to the mountains and dense forests around the waterfall, the entire waterfall looks particularly spectacular. It is an excellent online celebrity taking pictures after the first-line waterfall. point. I don’t know, have you ever been to or heard of the North Zhejiang Grand Canyon in Anji? What is your impression of the scenery here? If you haven’t been, do you plan to travel here on May Day? Welcome to leave comments.

There is a fascinating place in everyone’s heart. In the magnificent China with mountains, lakes, seas, and beautiful rivers, there are countless beautiful scenery, and many people will also have a fascinating place in the minds of many people. I still remember the most memorable ad slogan: “Life is like a journey. You don’t need to care about the destination. What you care about is the scenery along the way and the mood of seeing the scenery.”

With the train passing over lakes, mountains, and grasslands in the picture, the man in the carriage is holding a camera and looking at the scenery along the way outside the window, accompanied by the ad slogan “Let the soul travel”, so I still remember it as new, this freedom Free and easy also let me embark on the journey of travel. After walking through most of China, I also saw a lot of landscapes that looked similar but not dissimilar.

What fascinates me are the lofty mountains and rivers in the north and the beautiful mountains and rivers in the south. However, in Anji, Zhejiang, which is at the 30th parallel of the latitude of the world’s geographical location, the largest new tourist attraction in the Yangtze River Delta region—the canyon scenic area known as the “Qinghai-Tibet Plateau” in Zhejiang has become my trip. A place to explore for travel.

Zhejiang North Grand Canyon

The fatigue of the journey is always gone at the moment of reaching the destination. Anji is an excellent tourist destination known as the “land of three cleans” in recent years, integrating scenery, leisure and entertainment. I have also clocked in a lot of popular attractions in Anji, but this hidden beautiful landscape has not yet been involved. At the beginning of the itinerary, I did my homework on the scenery comparable to “the Qinghai-Tibet Plateau of mountains and rivers”.

30 degrees north latitude is a peculiar and mysterious special latitude with many natural wonders. In China alone, there are special attractions such as Mount Everest, Sanxingdui, Shennongjia, famous caves for the ages and so on. In Zhejiang, there is the North Zhejiang Grand Canyon, which began in early summer. The North Zhejiang Grand Canyon, which flourished in the Han Dynasty, is even more beautiful. It also has a very rich cultural landscape and a splendid Confucian and Buddhist cultural landscape.

The North Zhejiang Grand Canyon is located at the border of Tianhuangping in the southern boundary of Anji County and the source of Taihu Lake in the northern boundary of Lin’an City. The entire scenic area is built on the mountain, with a total area of ​​38 square kilometers. It consists of Dahanling, Dongling, Shiling and Longxu Mountains. , The five scenic spots of high mountain farm holiday.

Nearly a hundred thousand-meter-long majestic mountain peaks were first called Dahan’s 72 Peak. As early as the end of the 22nd century BC, it was recorded that Dayu came to the 72 Peak to control water and planted willow trees at the source of Taihu Lake, thereby creating willow trees on the peaks of Taihu Lake. Shade, so that the floods no longer flood. In 117 BC (the fifth year of Emperor Wu of the Han Dynasty), Emperor Wu of the Han Dynasty led an army to attack South Vietnam. Seeing that the valleys and mountains were connected, the terrain was dangerous, and the defense was invincible, so he set up camp on the spot, and the northern Zhejiang Grand Canyon was also named after this.

At the same time, the North Zhejiang Grand Canyon is the origin of the “Buddhist Revival Movement”. There are Honglin Temple, Dushan Temple, Xishan Temple, and Xujia’an in the mountains, which are called the “One Leaf of Buddhism” in the south of the Yangtze River. Integrating the tranquility, purity and tranquility of Zen Buddhism with the unity of nature and humanity in Confucian culture, natural landscapes and history and humanities complement each other.

The Honglin Temple was built in the Sui and Tang Dynasties and has a history of more than 1,000 years. The stone sculptures of Maitreya Peak, Tathagata Peak, and Guanyin Peak are fused in the mountains and rivers, and the flowers and the grass reveal the tranquility of Zen. Today, the incense of Honglin Temple is still vigorous, and the incense lingers around the tip of the nose can feel the charm of “no peak is not strange, no stone is not steep, no temple is not ancient”.

Walk along the stone steps along the northern Zhejiang Grand Canyon Tour trail for about 40 minutes, and you will see the first waterfall of Huangpu River Source at an altitude of 680 meters. There are mountains and water. There are many currents in the canyon, many large and small. waterfall. And here is the largest waterfall in the canyon. The waterfall has a drop of 30 meters and a width of up to 5 meters. It is controlled by the north-south fault and forms a steep ridge perpendicular to the direction of the canyon. The crystal clear ice waterfall will fall on the rocks to become a waterfall. The source of the Huangpu River, the mother river of Shanghai, is here, so it is also called the “small source of the Huangpu River.”

There is also a “first-line waterfall” with a trickle that is eye-catching. The water flow is not large, but it flows all the year round. It is said that the flow has not stopped even in the dry season. The canyon is lined with dense forests, accompanied by mountains and streams all the way. Because of the historical heritage of Buddhism and Confucianism, the strong Buddhist cultural atmosphere also puts an ancient and mysterious atmosphere on the canyon.

The first half of the North Zhejiang Grand Canyon is mainly interspersed with strange rocks, stone caves, and small lakes and waterfalls. Satisfied with “good-looking”, of course it must be fun. The brave attempt to face the abyss is the real warrior. The glass bridge has long become the “standard configuration” of the scenic spot. The “Yingbin Bridge” of the North Zhejiang Grand Canyon, which was completed on October 1, 2018, is the first 7D experience glass bridge in Anji County. The glass trestle bridge connects two peaks with a total span of about 170 meters, with a drop of about 107 meters.

Underfoot is the rocky cliffs, coupled with the sound and image quality of holographic 7D, each step will have different cracks and sound effects, it can be said that every step is “thrilling”, allowing people to experience the high-altitude glass in an all-round way. The excitement and sense of technology of the suspension bridge. “The most fascinating is always the most dangerous.” When you hang on the glass trestle, you can overcome your inner fear. Under the thrills, let go of the surprises in your heart. Surrounded by towering mountains, the scenery at your feet is unobstructed.

Below the high-altitude glass suspension bridge is the Great Canyon of North Zhejiang, with a total length of 1,480 meters and a drop of more than 138 meters. The drifting slides are S-shaped, U-shaped, and 360-degree roundabouts, like a giant dragon about to take off. The momentum is extraordinary. In the hot summer, the cool and exciting rafting trip will let you know what is called “big ups and downs”. Just climbed to the “peak of life” and was immediately “thrown to the bottom”.

In addition to glass suspension bridges, floating in the sky, there are also cliff swings, sky mirrors, 360-degree bicycles, rotating swings, time slides and other recreational facilities. We have seen many high-altitude challenge projects of Internet celebrities in large and small scenic spots in China, but few scenic spots can group these high-altitude challenge projects together. They are basically individual challenge projects, or they are not high enough. , The thrilling level is greatly discounted, etc., or the project tickets are too high, but the North Zhejiang Grand Canyon can be said to be quite generous. Not only does its territory include the most popular high-altitude challenge projects in China, but the price is also quite affordable. , So that tourists can not only enjoy the mountain and water here, but also challenge the high-altitude project, which adds a lot of fun to travel.

There is a copy of the book “The American Practical Navigator” by Nathaniel Bowditch, first published in 1802 on each of the US Navy ships.

This is considered an encyclopedia about navigation, filled with data on the longitude and latitude of many places, from Bugio lighthouse in Lisbon, Portugal, to Kannonzaki lighthouse in Yokosuka, Japan.

The book provides detailed instructions on how to use a hexagonal glass to measure a ship’s current position by observing the Sun, Moon, stars, and horizon. However, the presence of this book on board is only a ritual, as the US Navy has long been accustomed to using electronic charts based on GPS, Nikkei Asia said.

But the threat of electronic warfare from rivals like China, forcing the US Navy to consider the possibility of reusing the supposedly outdated navigation system, in preparation for the GPS system scenario prepares the enemy. disable.

Combining ancient and modern

In August 2020, the USS Patriot, an Avenger-class minesweeper of the US Navy stationed at the port of Sasebo, Japan, crossed a distance of 1,700 km into the western seas solely by astronomical positioning.

Every afternoon, sailors would take a hexagonal glass, a centuries-old measuring instrument, to measure the angle of the Sun at its highest point in the day. The data will be fed into a computer program called the astronomical estimation system of latitude and longitude, also known as STELIA.

Sailors also observed the angular distances between the horizon and the Moon, the planets and the stars to calculate longitude and latitude. On the command tower, a navigation team consisting of the captain, subordinate officer and the pilot uses manual measurement data to control the ship.

Astronomical navigation has disappeared from the US Naval Academy curriculum since 2006, because it was deemed obsolete. But since 2015, the technique has been reintroduced into the program, to teach students how to measure and apply math to locate.

The re-teaching of astronomical navigation has been prompted by the acknowledgment that the US armed forces are increasingly dependent on digital systems. An attack on the GPS system that the US military is relying on, could limit the capabilities of the world’s most powerful military.

This concern becomes even more urgent as China invests heavily in electronic warfare and cyberspace.

Peter Singer, an expert at the Center for New Security of America, said the battle to kick off the next big war will take place in silence. In other words, it’s the war in cyberspace.

If digital communication was to be attacked, the US Navy would have to rely on the natural world, ears and eyes to survive, which is the reason for the return of the hexagonal glasses.

Learn how to position birds

Mr. Singer said that in addition to the astronomical navigation system dating back to the 18th century, the US should study another smarter navigation system for navigating ships, or guided missiles without relying on GPS. , similar to how birds migrate annually.

One sailor is working on calculating longitude and latitude based on Bowditch’s book. Photo: US Navy.

“The way they (the birds) move is not memorizing, it’s how they perceive Earth’s magnetic field. Some insects can do this too, so in-depth research is needed to develop a digital version of how birds move, ”says Singer.

The U.S. Defense Advanced Projects Research Agency (DARPA) is pursuing the Adaptive Navigation System project, a navigation technique that can work in buildings, under dense canopy, under water and ground. This system is said to be superior to GPS.

In February, a team of scientists released a report stating that birds may have global GPS systems.

“The precise navigation of these little birds is amazing, as they move alone across the sea, across the vast desert and through extreme weather conditions is one of the long-standing mysteries. behavioral biology “, a British scientist wrote on the World Economic Forum.

This may be the answer the US military is looking for in its defense mission against electronic warfare operations by China and other adversaries.

Billy Fabian, senior analyst at data analytics firm Govini, said preparing for the scenario of digital communication disruption is crucial, given the potential confrontation with China.

Specifically, at noon, sailors will take a hexagonal glass – a positioning tool that has existed for centuries – to measure the angle of the Sun at its highest point in the day. The data will be fed into a computer program called the Astronomical Latitude and Longitude Estimation System, or STELLA. They also observed the angular distances between the horizon and the Moon, the planets and the stars to calculate latitude and longitude.

On the jetty, a crew consisting of the captain, subordinate officers and the pilot used the above data to control the ship night and day.

The return of astronomical navigation

The Nikkei Asia Financial Times reported that astronomical navigation, or space travel navigation, disappeared from the US Naval Academy curriculum in 2006 because it was deemed obsolete. But in 2015, the school reintroduced this technique as well as sent students to a planetarium to teach how to measure and apply mathematics.

The return to this method of positioning was prompted by the realization that if the US armed forces increasingly relied on digital communications, a blow to the Global Positioning System. (GPS) – on which this communications system relies on – could make it difficult for the army considered to be the most powerful in the world. That concern is growing in the face of China’s increased electronic and cyber-warfare capabilities.

Peter Singer, strategist at consulting firm New America and author of “Ghost Fleet: A Novel of Next World War” (roughly translated: Ghost Fleet: Novel of the Next World War) commented: “Battle The opening battle of the next great war will take place in silence ”.

According to him, this battle will not be the same as the battle of Pearl Harbor that dragged the United States into the war with Japan in 1941, nor the horrifying battle that opened to the Iraq War in 2003. “It may even have been and is already happening.” Because, in cyberspace, enemy moves still happen weeks, months or years before the outbreak of war.

If digital communications were to be removed, the US Navy would return to the natural world, relying on eyes and ears to survive. Therefore, a return of the hexagonal glass is imperative. But the strategist Singer believes that there are still two other options than this 18th-century utensil.

One is to build a more flexible communications network and improve network security to help the military combat any GPS-related challenges. Second is the development of highly intelligent systems that do not require GPS.

“For example, there is research showing that rockets can fly by navigating against a magnetic field,” says Singer. He equates this with the ability of birds to migrate as they travel thousands of kilometers to reach almost exactly one destination every year.

Answering Nikkei Asia, he explained: “It is not because they remember the way. That’s how they perceive the Earth’s magnetic field. The same goes for insects. So there has been high-tech research on developing digital versions of the way birds and insects navigate.

“Learn” from birds

The Department of Defense Senior Research Projects Administration (DARPA) is pursuing the so-called Adaptive Navigation System. This GPS-equivalent method of positioning, navigation, and time will work even in poorly wave places such as inside buildings, in canyons, in dense woods, underwater and underground. .

In February, a group of scientists including Professor Richard Holland at Bangor University and professor Dmitry Kishkinev at Keele University published a report indicating that birds can possess a “global GPS system. “.

“The amazingly precise navigation of these little birds – as they travel alone over stormy seas, across vast deserts, and through extreme weather and temperature extremes – has been one of the the enduring mysteries of biology, ”wrote British scientists for the World Economic Forum.

“An evidence-gathering agency has shown that the Earth’s magnetic field is one of the most likely theories for this mystery. It is thought that the different parameters of the Earth’s magnetic field could form a network of maps that birds will fly with, ”they said.

“If birds know that magnetic field strength increases as they go north, they will be able to detect their position on the North-South axis wherever they go,” the report said. said the report. This means that the birds are essentially navigating using a system similar to Cartesian coordinates – the basis of modern GPS navigation.

Nikkei Asia asked Holland if anything from bird navigation could be used in the military. “In theory, the Earth’s magnetic field could be used as a positioning system,” he said. However, he warned: “It is not clear whether this system can be used on a global scale as GPS could, since there are several locations on Earth that share the same characteristics. magnetism”.

However, this could be the answer the US military is looking for in its mission to protect against electronic warfare by China or other countries.

Billy Fabian, an expert at data and analysis firm Govini and a senior colleague at the Center for New American Security, says it’s important to prepare for the scenario where communications are disrupted. when considering the nature of a potential war with China.

“A future conflict between the US and China will be different from past conflicts in two respects,” he said. One, every sector will be highly competitive, and that’s different from what we’re used to. Second, we will be under enormous time pressure. Most of the places that you can imagine we will fight in the future are in the backyard of China, but one ocean away from the American continent.

The US military is also practicing the concept called “mission command”. Accordingly, the commanders at the front lines are empowered to plan, coordinate and execute decisions without having to ask for instructions from their superiors. In this way, small units can continue to operate even when communication is interrupted.
