That’s how SpaceX prepares to send astronauts to orbit with Dragon

Although after the explosion of the prototype manned capsule there were huge complications in preparation for the second Dragon mission, SpaceX is already behind the worst, as evidenced by the latest tests with the evacuation of astronauts.

The Elona Muska company has already carried out a fully successful Dragon flight to the International Space Station, so now it’s high time for a manned flight, with astronauts on board. It will be a historic moment for the American space industry. For now, SpaceX has not revealed when this event will happen, but experts believe it will be the end of this year.

Before this happens, however, there will be one more flight. It will rely on the astronaut evacuation system test if a crash occurs during space flight. Of course, there will be no astronauts on board the capsule either. The test will take place in a few weeks. If all planned tasks are completed successfully, the first astronauts, Douglas Hurley and Bob Behnken, will be able to embark on a maiden flight.

Meanwhile, SpaceX and NASA engineers conducted tests at Trident Basin on Cape Canaveral regarding the safe exit of astronauts from the capsule already on board the GO Searcher rescue vessel and providing them with professional medical assistance. Interestingly, the tasks involved a rescue helicopter that transported astronauts to the hospital.

The experiments were also carried out on the famous LC-39A launch platform, from where space flights will take place. Then astronauts will have to learn how to quickly get out of the capsule, and rescuers will help them in this rather complicated process already directly in the waters of the Atlantic Ocean. If you want to see more pictures from rescue experiments, then you can do it here.

Another threat on our smartphones! A serious Bluetooth vulnerability has been detected

Security specialists have just revealed another vulnerability in the popular standard, which allows you to take over the device remotely without major difficulties. Manufacturers of mobile devices are already preparing patches.

The vulnerability was named KNOB and affects almost every device equipped with Bluetooth connectivity, and it is a vulnerability in the authorization protocol that can be used to conduct a man in the middle attack between two paired devices. But what is most important in all this, according to researchers, there is no evidence that anyone used it in this way. However, this is possible because the vulnerability reduces the encryption strength of the combination used to connect two devices together and take complete control over them, and the case is so serious that it requires changes to the official Bluetooth specification.

And how exactly does this vulnerability work? Quite creative, because the attacker instead of using the brute force attack, i slick tips.e. breaking passwords by checking all possible combinations, can join the pairing process, where devices voluntarily connect to each other, exchanging public keys. Although the keys change with each pairing, but if the attacker gains access to them early enough, they can force a shorter key during the next verification, even a 1-symbol one, while remaining unnoticed.

The vulnerability was detected by researchers at Singapore University of Technology and Design, Oxford and CISPA Helmholtz Center for Information Security, who named it KNOB from Key Negotiation of Bluetooth. Tests were carried out using more than 17 different Bluetooth chips that are popular in consumer products and it turned out that all of them are vulnerable to the attack using the vulnerability – Intel, Broadcom, Qualcomm, Chicony or Apple, no manufacturer has avoided vulnerability, and only devices using Bluetooth Low Energy turned out to be insensitive.

However, what is worth emphasizing, although this vulnerability is widespread and affects almost all Bluetooth devices, its use forces the attacker into very specific conditions. e.g. it must be in range of both devices during the pairing process, and then intercept, manipulate and resend negotiation messages regarding the key length to both devices, while blocking transmission from both. What’s more, the whole process must be repeated every time encryption is turned on, so this is a big challenge for a hacker – one way or another, you can not underestimate this, so the largest manufacturers are already releasing the appropriate patches, and Bluetooth SIG changes the specification of the standard, forcing manufacturers to use a key of at least 7 characters in future devices.


Soon everyone will be able to follow whoever they want straight from the satellite

Josef Koller, a former senior adviser on space policy at the US Secretary of Defense’s office, announced that he is creating a project with the enigmatic sounding name GEOINT Singularity for all inhabitants of our planet.

GEOINT Singularity will be a gigantic constellation of microsatellites that will orbit the Earth in low orbit and observe all, even the wildest areas of it. The devices will also offer quick access to a global 5G network. The goal of the project is to enable observation and tracking of any person without a break, i.e. 24 hours a day, 7 days a week.

Until now, such systems were reserved only for government agencies, but Koller wants to give power over them to the people, so that every inhabitant of our planet, for free and in any dimension, can watch / preview all areas of our planet, animals and people. It may sound scary, because it will affect people’s privacy, but if everyone can use this powerful system, then the fears will disappear and the world will become a better place. At least, that’s the vision of a former employee of the U.S. Secretary of Defense’s office.

GEOINT Singularity will be based on the latest observation systems that can be carried out despite the cloud cover, as well as at night. The entire installation is to use the benefits of a super-fast 5G network and be supervised by artificial intelligence technologies. Interestingly, the system is to be ultimately associated with mobile devices of the Internet of Things, thanks to which the system is to collect information about the location of each person and the activities it performs without interruption and in all circumstances.

Koller does not hide that GEOINT Singularity can become a Big Brother in the Chinese fashion of the Citizens Assessment System, but it is this system of permanent surveillance and the availability of information about each citizen that causes fewer crimes, and people are more open to each other and empathetic. We’ll live and see if Josef Koller’s idea will be implemented at all and will work.

Zapata is building a flying sports car that will reach 400 km / h

The French world champion in watercraft races has successfully defeated the English Channel and will soon start a futuristic vehicle construction project that will set new historical records.

The 40-year-old fan of extreme sports secretly builds a unique flying vehicle with his team of exquisite engineers, which has never been seen before. It is supposed to be a sports car, which will reach the speed of about 400 km / h in the air and have a range of about 120 kilometers.

At the moment, little is known about him, but it is no secret that his first tests were successful. The invention is intended to have 10 electric motors. The Frenchman revealed that for the next two weeks he would be resting with his family after the hard struggles of a flight over the English Channel, and later he would work on completing his new flying love.

Zapata also revealed that the invention will be ready later this year. It is not clear whether it will be another flying taxi, only in the sports version or a flying car that can start from the parking lot. Either way, it’s sure to catch the attention of extreme sports fans.

A flying car called PAL-V Liberty. Fig. PAL-V Liberty.

It is highly probable that we will see this unique vehicle officially during the Summer Olympic Games in Tokyo, which will take place next year. The Japanese announced that there will be the most phenomenal and technologically advanced devices in the history of mankind.

Interestingly, the French government was also interested in Zapata’s ideas, especially Flyboard Air. The local army co-financed over EUR 1 million on new vehicles and new vehicles. We can therefore expect that soon the soldiers will be moving along futuristic vehicles from futuristic vehicles straight from sci-fi films.

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.
