Astronomy A successful course of the Hayabusa-2 mission to save humanity from disaster

The Japanese published new images from the moment the probe approached the surface of Ryugu and the view of the landing site itself. Based on the data, we will now be able to prepare a rescue mission.

The Ryugu planetoid belongs to one of the oldest objects traversing the Solar System. Its careful study will allow us not only to develop technologies that will allow us to protect against cosmic rocks, but also 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 close flight of the probe over the surface of Ryugu and landing on it provided us with extremely interesting information. Scientists have revealed that there are hydroxyl minerals, which indicates that once, on the primeval celestial bodies from which Ryugu was formed, there was water, and in it the bricks of life or even simple organisms.

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 second landing of the Hayabusa-2 probe on Ryugu took place on July 11 this year. The place of landing was the area of ​​the crater, which was created as a result of impact of the impactor from the Japanese probe. 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 impact of a 4.5 kilogram 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.

Facebook games are secretly working on Assassin’s Creed and Splinter Cell in VR

Virtual reality was supposed to be a huge breakthrough in the video game industry, but ultimately it will be only a temporary fashion … unless the secret project of Marek Zuckerberg changes something in this topic.

It can not be denied that fans of the stealth series from Ubisoft were very disappointed when it turned out that during any of this year’s industry events there was not even the slogan of the new Splinter Cell. Fisher himself has many dedicated devotees who since 2013, ie the page entitled Blacklist, can not wait to return and regularly search the web in search of even mention of a possible debut of the new game from the series. Is there a chance that they will finally find something?

It turns out that yes, because today’s reports suggest that the cult brand has taken … Facebook – although we are talking here about the exclusive version of VR, so there is no guarantee that it is a new game, not a modification of any of the earlier versions. In any case, Mark Zuckerberg himself was supposedly involved in the negotiations about the license, who personally has to watch over the success of this project, which in fact concerns two productions.

In addition to the mentioned Splinter Cella, we also have a game from the Assassin’s Creed universe, also in virtual reality. And unfortunately it’s all assurance, because, as sources close to the social giant say, he does not have a specific idea yet, what to do with all this and only knows that he wants to tempt more people to reach VR. And there is some sense in that, because the successful return of Splinter Cella and good Assassin production would surely interest players in this technology.

Unfortunately, however, it should be noted that VR is not as popular as developers would like it, and although the “virtual versions” of well-known brands, such as Skyrim or Fallout, sell quite well, there is still a lot of spectacular success. Perhaps the situation will change slightly after the release of next-generation headsets, which are to deal with many ailments of predecessors, such as irritating amounts of cabling or technical deficiencies causing nausea. Anyway, the new Splinter Cell is always great news, so we’re waiting for more information in the topic.

Automotive EU authorities say that electric cars can not be silent!

We just find out that the new regulations require manufacturers to equip their new electric vehicles with devices that imitate the sound of the engine, all for safety reasons.

It would seem that one of the greatest advantages of electric vehicles is the fact that they can operate almost silently, especially compared to their fuel-powered competitors. Meanwhile, new European regulations make us forget about it, because car companies have just been forced to … install devices that emit sounds similar to those of classic engines.

The new European Union regulations that come into force today apply to all new four-wheeled electric vehicles – these must now be equipped with the AVAS, or Acoustic Vehicle Alert System, which emits sounds similar to a traditional engine when the car’s speed drops below 20 km / h. And although most of us seem absurd, there are organizations that are demanding even greater tightening of these regulations.

As the BBC informs, although the British Guide Dogs organization welcomed the changes, it is still going to fight for electric cars that emit sounds at any speed. All because of the safety of pedestrians, especially the blind, who are guided by hearing while moving on the streets. According to British Transport Minister Michael Ellis: – New requirements will provide pedestrians with more safety when traveling on the road.

The device that emits the sound activates at a speed lower than 20 km / h, because that’s when cars are most often found near pedestrians. From 2021, all new electric cars will have to be equipped with them and we are not talking only about new models, but completely all, which means that owners of such vehicles must prepare for a new expense. We would also like to remind you that the United Kingdom has already announced in 2017 that it intends to strive for a total ban on the sale of fossil-fueled vehicles and that it will go completely electric by 2040, so new regulations are absolutely necessary here. But are you sure? Be sure to let me know what you think about it.

NASA astronomy has announced a mission to Titan, the moon of Saturn. The drone will look for signs of life

The exploration rovers slowly but inexorably go to nothing. They will be replaced by advanced drones that will search for traces of life on alien planets and their extraordinary moons much faster, cheaper and safer.

NASA has just announced the mission of a drone on Titan, the largest moon of Saturn. The launch of one of the largest and most risky ventures in the history of the agency is to take place in 2026, and in 2034 the drone will land on the surface of the facility. The mission will be part of the New Frontiers program, which aims to study alien worlds in the solar system.

Titan is one of the most interesting objects known to us. The surface has very low temperatures, there are natural reservoirs of liquid hydrocarbons, and the atmosphere is dominated by nitrogen, in other words, like on Earth. Astrobiologists believe that there are ideal conditions for the emergence and flowering of various life forms. Titan in its present form resembles the Earth from billions of years ago.

The exploratory drone will be equipped with a nuclear propulsion, or rather a radioisotope thermoelectric generator, eight rotors and a set of research instruments. According to the plan, the mission will be carried out in an area called Shangri-La. It lies on the equator of the moon and abounds in sand dunes. They bring to mind the views of African Namibia. The Selk crater will also be carefully examined. In it, there are signs of once-occurring water, as well as complex organic molecules based on carbon.

The scientific mission is to last 2.5 years. During its lifetime, the drone will travel about 175 kilometers of sandy areas and will fly over methane and ethane tanks. The device will also examine the state of the atmosphere. Scientists plan to take thousands of photos of the whole globe, and later find interesting formations that can tell us the history of the evolution of the moon.

On the occasion of the drone mission to Titan, it is worth adding that the first mission of this type of mankind in the history of mankind will take place next year. Then, a drone and a rover as part of the Mars 2020 mission will fly to the Red Planet.

Mobile Soon people will be waving smartphones. Then you will know that they have Xiaomi

The Chinese are developing their innovative technologies in the world of mobile devices at a frantic pace. We can safely say that they have already defeated the Americans and Koreans on this issue, but they have not said their last word yet.

A very interesting but controversial idea came from the engineers of the popular Xiaomi company, which offers top smartphones at a reasonable price in many countries. Soon, their happy owners will receive a new boon in the form of the possibility of controlling the smartphone using gestures evoked in a unique form. It’s about a solution called 3D Air Gestures.

Behind this enigmatically sounding name was the execution of gestures in the air. So, to turn on an application that interests you, he can make a gesture with a smartphone in the air, for example, sketch the letter Y, and on the screen, for example, YouTube will appear. For many it will probably be an interesting innovation, but rather they will not use it on a daily basis, because much faster you can simply click on the icon, but better rydz than nothing.

On the above video you can see the 3D Air Gestures gesture control function in action. At the moment Xiaomi is still testing it among employees, but it is almost certain that soon it will go to the manufacturer’s smartphone along with the new version of MIUI 10x software.

Apple is preparing for a revolution. The first iPhone 5G is expected to appear next year

The first Apple brand phones with a 5G modem are expected to appear next year, but not all models from 2020 will receive this module.

In selected countries around the world, the 5G network is already operating, and the first manufacturers have started selling smartphones compatible with the new generation of base stations. For now, however, these are devices with Android such brands as Samsung, LG or Oppo. The big absent 5G race is Apple.

Apple is not in a hurry to present the iPhone 5G.

Smartphones with 5G modules are today only an addition to the offer of her android competition, not her core. You can use them only in selected locations, and placing them in the phone’s housing clearly increases the cost of production, which would not be without effect on the high price.

This year, three brand new iPhones will debut, but the successors of the iPhone XS, iPhone XS Max, and iPhone XR will not get 5G modules yet. You have to remember that in the case of the iPhone, LTE modules also appeared with a slight delay in relation to the market. However, as reported by the portal, the first iPhone 5G will appear a year later.

New modems and new iPhone sizes in 2020.

Allegedly, in 2020 the size of screens used in iPhones will change. Two basic models in the offer, i.e. successive successors of the iPhone XS and iPhone XS Max will have 5.4-inch and 6.7-inch displays. In turn, the next successor to the iPhone, the XR, will again have a 6.1-inch panel – this time in OLED technology.

Just as all three Apple phones will come together in 2020 in terms of image display technology, the way to distinguish the wireless data transmission module is to begin. Two top models are to receive the 5G module, and the cheaper one is to hit the stores only with the LTE module. It sounds plausible, and such a division of the offer would make sense.

It is worth adding that the supplier of the first 5G modems, which will be installed in iPhones, is supposed to be Qualcomm, with which Apple has recently buried a war ax. Intel gave up the mobile market. It is not inconceivable, however, that Apple will buy a mobile department from Intel since Tim Cook plans to independently manufacture 5G modems already in 2022 or 2023.
