History is happening on Earth’s orbit. Here is a sail propelled by the sun

The Planetary Society reports that the unique mission of an innovative solar-powered satellite is going well, and as a proof, astronomers have shown phenomenal images of sail and Earth.

A few days ago, the microsatellite set itself in the direction of the sun and the release and distribution of the sail took place, and thus the most breakneck part of the whole mission began. The organization has also published images of our beautiful planet made by the device and the sail itself. We can see with our own eyes that it performs excellently.

LightSail 2 consists of four small sails made of a material called Mylar. Together they have an area of ​​32 square meters. Sail does not have a traditional drive. According to the plan, it is to travel on Earth’s orbit, pushed by photons from our daily star.

The association wants the device to fly around our planet. If we succeed, we can talk about a real revolution in the missions of small space installations. The lack of the need to install a drive in microsatellites will not only drastically reduce the costs of space missions, but will also speed up the construction of devices and will prolong their operation in orbit.

Plans for the use of such propulsion in space ships appeared in the 1930s, but then it was pure science fiction. The Planetary Society in 2015 conducted the test of the first prototype LightSail 1. Then it was not without problems, but eventually the device according to the plan entered the atmosphere and burned over the southern Atlantic.

Researchers collected valuable data that allowed them to build a new prototype. Now an association made in 1980 by Carl Sagan, Bruce Murray and Louis Friedman will carry out another experiment. This time the sail will be more advanced. The LightSail 2 mission started on June 25. The device flew into orbit on board the Falcon Heavy rocket from SpaceX as part of the STP-2 mission for the US Department of Defense.

Bird eggs can communicate at an advanced level

Recent research suggests that among birds, we can observe a phenomenon that looks like science fiction, namely embryos found in eggs can communicate with each other.

Of course, we all know that chick communication is at the highest level and we can easily hear when they demand food from their parents, but according to researchers they can do much more, that is, communicate with each other while still in eggs, and this form of communication is supposed to affect behavioral and psychological characteristics of newly hatched individuals from one hatch. It is true that a long time ago we managed to prove that birds and other oviparous creatures receive sensory information by the shell, designed to prepare them for life outside the egg, but the latest discovery is something more.

New research by the Spanish University of Vigo suggests that the gull embryos are able to obtain the necessary information not only in the classic way, but also from their siblings, still in eggs. In recent years, a lot has been said about small turtles communicating with each other about common hatching, and some birds and reptiles can do the same because of the sounds sent out from inside the shell, but we still have not answered the question whether these chats between eggs serve more.

Researchers have found that embryos not only hear and respond to their parents ’emergency calls, but are also completely different from hatchlings in behavioral and developmental terms, from chicks who were not able to hear their parents’ calls. This is very interesting in itself, but that’s not all, because when we put an egg that has been subjected to the factors mentioned here, among other eggs that it did not experience, they also show the changes described above, which means that embryos can communicate with each other, most likely using vibrations.

To confirm their theory, scientists simply collected 90 eggs from the nest of a Roman gull on the island of Salvora, which they divided into groups of 3 in the laboratory and placed in special incubators. Then 4 times a day, two eggs from each group were stimulated to suggest the presence of a predator, and then put aside – of course there were also test groups. After hatching, it turned out that embryos that were in one nest with eggs subjected to sound stimulation behaved in the same way as siblings, although they did not hear these sounds themselves. What’s more, the chicks hatched longer, they were quieter, they were more cowering when they saw the threat, they were smaller and had shorter legs. In short, they developed certain defensive features, as if they had heard warning signals themselves, so the only option is to share information between embryos.

See how the Spacehip starship prototype will jump to a height of 200 meters

The Elona Muska company has a great goal. It is landing on the surface of the Moon faster than NASA. Then it will be the first private company in history to do so. Before that happens, soon Starhopper will reach heaven.

The billionaire announced that measuring 18 meters high and 9 meters wide, the test structure made of stainless steel, will rise to a height of 200 meters already on August 12, and in the next 2-3 months will reach the space. For now, SpaceX engineers managed to reach a height of about 20 meters, so the largest flights ahead of them.

The trials will continue on the prototype located in the Boca Chica resort in Texas, but will soon also start at Cape Canaveral, Florida. It should be emphasized here that the first prototype is more advanced, because it was made faster, and it is on it that more crucial tests are conducted.

SpaceX announces that the announced tests will still be carried out on one Raptor engine, but three will already be used in the first experimental flights into space. Ultimately, the full-sized version of Starship will have more than 40 engines that will be necessary for flights to the Moon, Mars and other planets of the Solar System.

According to the vision of Elon Muska, Starship is to take even 100 space tourists on board, and travel with them to foreign worlds. Musk also provides for ship travel between the Earth’s metropolises. This is to be the fastest means of transport that our civilization has created throughout its history. The first mission of the ship is to take place in 2021, and the landing on the Moon with crew in 2022 or 2023.

A popular Chinese vlogger accidentally showed a real face and … lost her fans

Success in social media is most often addicted to the appearance, as the popular Chinese vlogger, who by accident mistakenly showed fans his true self, became a painful sight.

The woman, working in the media as Your Highness Qiao Biluo, turned out to be a decade older than the persona she presented to others in her materials, using special filters. Everything seemed to be a mistake during one of her last live streams on Douyu platform, which showed viewers the true face of their idol – beautiful and young goddess disappeared, who thanks to “sweet and soothing voice” gathered on her channel 100,000 followers, and her place she took a much older, unknown woman.

What’s most interesting, the fans themselves asked Your Highness Qiao Biluo to remove the filters, because they have long suspected her of using them and showed them their true face, but she confessed that she could not do so until she received a subsidy of the total amount of nearly 12 thousand USD. Fans quickly mobilized themselves to action, and one of the people even paid $ 5,000 a month, but soon afterwards it turned out that completely unnecessarily, because as a result of the error everyone could see the idol’s face completely free, and this long did not even realize that something is happening – you can see it on the following material.

And although the incident quickly became a viral in China, due to the unexpected nature of this disclosure, it should be noted that the use of face filters in live streams in this country is very common. South China Morning Post even prepared a special document in which he revealed how popular stars make completely new faces, thanks to make-up and filters, completely different from those which nature has given them. Is there anything wrong with that? Everyone has to answer this question himself, but it can not be denied that the phenomenon is disturbing for many reasons.

First of all, some users confessed after the event that they feel cheated by idol and pulled on money, because it turned out to be something different from the ideal image presented in the media. On the other hand, after revealing it quickly turned out, in what times we live, because when Your Highness Qiao Biluo turned out to be a mediocre middle-aged woman, users immediately lost interest in it, even though they listened to her soothing voice afterwards. . Anyway, it’s good to be aware of how modern social media work, to avoid possible disappointment later – when it comes to the vlogger itself, after the initial outflow of fans, the popular material from the disclosure brought her 500,000 new.

Japan wants to create a superman. Human-animal chimeras will be created there

Scientists from the Land of the Rising Sun want to finally make practical use of the world’s latest technologies of genetic modification in living organisms. The first artificial superhuman will be built in Japan.

The research is conducted by Hiromitsu Nakauchi, along with his team of scientists from the University of Tokyo. Some time ago they created the world’s first pig-human chimeras, from which it was possible to take organs for transplantation in humans as part of tests.

However, the ambitions of the Japanese team are much bigger. Scientists want, by means of advanced genetic modifications, not only to create a system of mass production of organs replacement for people and to lay the foundations for eternal life, but also want to create a new species of animals that will have the characteristics and capabilities that have been reserved for humans.

Scientists are experimenting on rats and pigs because they are mammals whose body’s functioning is close to ours, human. The scientific world sees the possibility of creating pig-human chimeras, above all for the needs of transplantation. Such organs are to be perfectly matched to a particular patient, and the recoil risk is practically limited to zero.

The experiments involve injecting a embryo into the pig’s embryo, at the blastocyst stage, the inducible pluripotent stem cells of the patient who are waiting for the transplantation of the organ. Cells are made from somatic cells. In such a pig-human chimera, there are tissues, both animal and human. Only the kidneys that are transplanted are made entirely of the patient’s cells.

Researchers say blood vessels raised from human and porcine cells will not induce organ recoil in patients. The research conducted by Japanese specialists caused a huge wave of criticism in medical circles. Scientists accuse Nakauchi of violating all ethical principles, because the brains of chimeras and their reproductive organs are also formed with the participation of human stem cells, and this is a subject of great controversy.

Nakauchi, however, wants to approach this unrewarding topic from the most ethical and moral side. Therefore, his team will not create and kill embryos for no reason. The research is to be strictly controlled by the University of Tokyo authorities and government bodies. However, the aim of the Japanese is noble, they want to open a new chapter in the history of transplantology, which will be a quick and effective exchange of any organs on request.

This was the second landing of the Hayabusa-2 probe on the cosmic rock

Japanese astronomers from the Hayabusa-2 probe mission boasted a new movie from the second successful landing of the vehicle on Ryugu’s potentially terrestrial planetoid. Here’s the recording.

The first landing took place on February 21 this year and the second on July 11. Between the first and the second, there was also a bombing of the cosmic rock with a kinetic charge. Thanks to all three of these tasks, the scientists took valuable samples of the Ryugu surface.

A thorough examination of them will take place on Earth, as the probe will soon embark on a return journey to our planet. Obtained extremely valuable information will allow us to not only develop technologies that will give us a chance to protect against cosmic rocks, but also allow us to get to know the turbulent past of the formation of celestial bodies and the Earth and the flowering of biological life on it.

The Japanese believe that objects like Ryugu, before billions of years, could bring to Earth and initiate the flourishing of life as we know it. If in reality it was as they suggest, then life in the Universe may be more common than we think. It must be emphasized here that this object belongs also to the Apollo group, which means that in the future it may pose a threat to our planet.

The place of the second landing was the area of ​​the crater, which was created as a result of the impact of the impactor from the Japanese probe in April this year. This was the first bombardment of the planetoid in the history of mankind. We would like to remind you that the Small Carry-on Impactor (SCI) impactor is a 2.5 kilogram copper block that was formed under the influence of the explosion of 4.5 kilograms of HMX plastic explosive. It collided with the asteroid at a speed of about 2 km / s and led to the formation of a crater with a diameter of 10 meters.

During the latest landing, the vehicle collected further dust and rock samples from the surface of the facility. The Hayabusa-2 probe will provide collected samples from the entire 100 milligram mission to Earth for more thorough research. Therefore, this mission is considered historical. The probe should start returning to Earth in December 2019. The samples should fall into the hands of scientists a year later.

A 35-kilometer Hyperloop railway track will be built in Saudi Arabia

This is certain. Virgin Hyperloop One, owned by Richard Branson, head of the Virgin group, will build the world’s longest railroad of the future in the desert. It will be an introduction to the construction of a futuristic city of the future.

The project involves the construction of a 35-kilometer stretch of the Hyperloop route in the King Abdullah Economic City. The city is located between Mecca and Medina. The implementation of the entire undertaking will be carried out by Virgin Hyperloop One, which is currently a pioneer in the development of this technology in the world.

Currently, the company already has a full-size capsule and 500-meter test track under Las Vegas, where it successfully tests its magnetic rail technology. Virgin’s capsule has recently reached a speed of 387 km / h. The construction of the Hyperloop route is to begin within 2 years.

The Future Railway is just one of many futuristic projects planned by Prince Muhammad ibn Salman ibn Abd al-Aziz Al Su’uda, successor to the throne of Saudi Arabia. The Saudi Vision 2030 project involves the construction of a several hundred kilometer long Hyperloop route from Neom to King Abdullah Economic City, Mecca and Riyadh. The country’s authorities want to create a new Arab silicon valley in the northern part of the country.

Virgin Hyperloop One wants to build the future of Hyperloop, not only in Saudi Arabia. This technology is also very popular in the United Arab Emirates and India. Richard Branson’s company already has plans to build a network in Dubai and Mumbai. Recently, we also had the opportunity to see plans to build a global transport system based on Hyperloop. The company cooperates with DP World Cargospeed in this matter.

Norway will open remotely controlled salmon farms next year

When we think about the most important export goods, most often we can think of raw materials such as coal, oil and gas, but in some countries these are also … salmon that can be grown with the help of AI.

Norway produces and sends abroad the largest number of farmed salmon in the world. Last year it was 1.1 million tons. No wonder that producers are looking for newer solutions in the field of breeding, especially since this is not so simple. For example, feeding her now consumes half of all costs, and you can not forget about the so-called salmon salves, which feed on certain types of salmonids and contribute to breeding losses, because even if the parasite does not kill the fish, they can do some delousing methods, which costs the salmon business billions of dollars a year.

The answer to these problems is to be automated remote control farms invented by Arctic Offshore Farming (belonging to Norway Royal Salmon), where in large monitored farms in the open sea, full of appropriate tools, Norwegians will grow salmon and trout. We are talking about up to 3,500 highly specialized farms that can accommodate up to 400 million fish, which on the one hand are to respond to the constantly increasing demand for these fish, and on the other significantly reduce the cost of their production, even by eliminating the above-mentioned problems. Homesteads will be equipped with indicators, sensors and cameras that give operators the ability to remotely monitor the condition of fish, their feeding, cleaning the net and respond to changing environmental and meteorological conditions.

The feeding system itself is to reduce the cost of energy by 50%, and what’s more, the fish will be in the open ocean, some 10-40 meters below the surface, below the euphotic zone where salmon lice feed, so their mortality rate also decreases. Tests of the new solution will start next year, first off the coast of the Troms district, and if everything goes as planned, the farms will later be moved deeper into the sea. As for the infrastructure itself, we are talking about round pens with a diameter of about 79 meters, resembling huge fish baskets, each of which can accommodate up to 600,000 adults.

Ecological Large Hadron Collider will help to warm up nearby houses in winter

The most advanced machine in the history of mankind, thanks to which we can study the space surrounding us extremely precisely and discover the greatest mysteries of the Universe, will become environmentally friendly.

The Large Hadron Collider allowed our civilization to begin exploring the Universe in ways never before achieved. Unfortunately, these benefits are paid by the adverse impact of this machinery on the natural environment. The CERN center consumes unlimited energy during complex experiments. It is often as much as a large country needs.

Therefore, the authorities of the center decided to make the LHC more environment-friendly, according to the principle, let’s bake two birds with one stone. The project involves the use of huge amounts of energy not only on key physical experiments for humanity, but also their side effect to ensure a better life for thousands of inhabitants of Geneva.

The Large Hadron Collider has a special cooling system, assisted by water circulation. The liquid heats up during operation of the machine to 30 degrees Celsius. The resort authorities want to use some of the hot water and heat of air generated during the operation of other appliances and air conditioning systems to heat nearby houses. It’s about the Ferney-Voltaire region, where new housing estates are built for over 8,000 people.

Hot water from the LHC cooling system will be collected at point 8 and directed to the geothermal zone of urban development. Fig. CERN.

LHC will soon be expanded, and in the 20s it will be replaced by an even more powerful research device. The authorities are planning to gradually expand their ecological project to make the most of its potential and return the center to ecological tracks.

Recall that CERN plans to build a new particle accelerator called Future Circular Collider. It is to be 4 times bigger than LHC. Its length is to be as high as 100 kilometers, while the LHC has only 27 kilometers. The FCC will be ready in 2040, and the total construction cost is expected to amount to 11-23 billion dollars. The project is to take part Elon Musk with his company The Boring Company.

The official medals of the Olympics in Tokyo are made of parts of smartphones

The fast-paced Olympic Games in Japan, which will take place as early as 2020, are to overshadow with their panache and amazing ideas for the 21st century, all historic events.

We already know that the SonO ambassador has been Son Goku, and the mascots are to be small Gundam and Char Zak works that will be on board a special microsatellite. The robots will measure only a few centimeters high, but both will face a great cosmic mission to the glory of the homeland.

But it is not everything. There is also a great pro-ecological side of this great venture from the world of sport. Well, all Olympic medals were made of parts obtained from the recycling of smartphones. As in every electronics there are precious metals such as nickel, gold, silver or platinum, the Japanese have collected tens of thousands of broken and unnecessary smartphones, and then extracted from them up to 7 tons of metal, including 30 kilograms of gold, 4,100 kilograms of silver and 2,700 kilograms of bronze.

We are talking about collecting precious ores for the creation of 5,000 medals. The organizers have already informed that for the last 3 years they have managed to fully realize their extraordinary project, the first one in the history of this type of events. It helped in the implementation of 2.5 thousand special points, in which you could leave your beloved gadget with the thought of supporting this noble idea.

The action surprised not only the originators of the project, but the Japanese themselves. In total, nearly 48 tons of electronic equipment have been collected. One of the domestic operators supported the campaign by handing over as many as 5 million smartphones, which were left at the showrooms by customers.

Extracting precious metals from them is not such a difficult task, because you can obtain 0.034 grams of gold and 0.34 grams of silver from an ordinary iPhone. When we have millions of such devices at our disposal, they make big kilos. Most importantly, however, Olympians will receive extraordinary medals for their successes, in which millions of Japanese people have contributed to the creation.
