Well, scientists did not calm down, all open and yeah invented (still in science output, it does not happen). Vaughn poured in the reservoir 96 million black balloons! No, not to the pool for children to arrange, but no less interesting.
1. SpaceX is the second prototype of the space ship Starship in Florida. Why? Everything is simple — to accelerate the process of development and testing.
It is believed that the parallel development in two places at once much closer the day when the rocket will be ready for the first flight. Of course, it will cost a lot of money, but in the end, the project can quickly pay off. The advantages of the Starship ship a lot — for example, he will be able to deliver to orbit hundreds of Internet satellites Starlink, not 60 like now.
It is possible that the first orbital flight of the spacecraft Starship will take place at the end of 2020. So, at least, said Elon Musk — he was sure of it by 60%, as mentioned in his Twitter.
2. Meanwhile, the scientists said, some planets have a chance to survive the death of its star (no, not the Earth). The study found that small planets will be much easier to avoid exposure to the forces of gravity of their bodies than larger worlds.
Already now it is possible to assume that planets like mercury, Venus and Pluto can survive the death of our Sun, which will surely happen in a few billion years. But our Earth is much more complex world, which unites several different layers of rocks, therefore, to make assessments in this case is more complicated.
Computer simulations showed that planets are destroyed, breaking up into small fragments under the action of tidal forces if they fall at the time of death of the main star system in the so-called “radius of destruction”. So sooner or later, the Earth may suffer the same fate.
3. To useful news — scientists have created a hydrogel that can stop arterial bleeding! The new hydrogel consists of water, gelatin and a mixture of proteins and other chemicals. Wondered what its structure will be as close as possible to the connective tissues. When ultraviolet light falls on a gel that hardens and condenses, sticking to the wound and preventing leakage of blood. And all this for 20-30 seconds!
The researchers also report that experienced your hydrogel punctures the carotid artery of a Guinea pig, and put the gel on the wound. The hydrogel not only closed the wound (and saved the life of a pig), but also contributed to the wound healing. Interestingly, the wound in the head, too, so you can heal?
4. In 2019, Israel was quite a bit to become the fourth country to successfully deliver private robotic station on the moon. But… the unit “Genesis” from SpaceIL fell on the surface of the satellite, and crashed. And more recently, NASA published a picture of the crash site of the lunar module “Bereshit”.
For demonstration emerged after the collapse changes, NASA showed a photo of three years ago the same region of the moon. As can be seen, the so-called Sea of Tranquility after the fall of the object formed a bright spot with a dark crater in the middle, and the rays of length up to one hundred meters. Probably, the crater was formed during the destruction of the apparatus, rays from scattered fragments.
Judging by what’s left “tail”, the lunar spacecraft crashed into the surface at an angle of about 10 degrees. He was the little lander in history.
