The announcement did not come suddenly. It was clear that the American space agency NASA has to announced a new space flights. Because it is obvious that there is gap since Shuttle flights are suspended 2011. As time went on, the astronauts to get to space station ISS, there are still only a Russian Soyuz rocket.
Dependable powerful device, which almost never failed. Technical difficulties, unlike the vulnerable and changing American shuttles, almost none. While it may be narrow and uncomfortable, the Soyuz is valid for the safest taxi in space. However, for each flight, NASA astronaut on had to set aside $ 50 million.
It was therefore a matter of days will appear more modern and more spacious alternative. In the middle of 2012, the head of the German Aerospace Center (DLR), Jan Verner said he could not imagine that the private rocket company SpaceX and Boeing - which until now exclusively used for the transport of food to the ISS - rearrange the spacecraft.
The political relationship between the United States and Russia in 2012 was harmonious cooperation in space was narrow, collegial and friendly. If that were so, and more, Americans would no doubt give themself more time, until they start making spacecraft.
But times have changed dramatically. Because of the crisis in Ukraine, the tone between the United States and Russia became rougher. Unfortunately, in the universe. Therefore, the announcement of the American NASA, again wants to fly with their rockets, should be seen in a political context.
Already in April, NASA was almost entirely cut off cooperation with Russia, in addition to the international space station. Now that private companies should help to get NASA out of the impasse. Technically they can do it, there is no doubt. SpaceX and Boeing have already been successfully transported to space things. In the meantime, many NASA engineers working for the two companies. But I happen to have some things that attract the attention of:
In late August, in Texas during testing exploded a rocket. After the accident, the CEO of SpaceX wrote on Twitter that the rockets are too complicated. And they are. To drive people into space, they have to be very, very safe. This takes time and NASA must provide it to companies. Testing must be continued without haste. For the life of astronauts should not be questioned because of the current political strife and vanity.
Responsible would have to ask themselves how far they want to go with the escalation of the conflict and the rattle of weapons. Deputy Prime Minister Dmitry Rogozin, advised the United States to send astronauts to ISS with trampoline. On the other hand, the head of NASA believes that the world's leading nation in space exploration should not be dependent on any other country. But now it is. As well as Russia. One nation in the future will not be able to explore the universe itself. The best proof of this was the great work together Europeans, Russians and Americans on the international space station ISS. And to Mars can only join forces to arrive. And with all due respect: the best astronauts are also cosmonauts.

Your brain replaces the blurry images with static images of your next object of focus. Whatever you look at after moving your eyes appears to stay still for a long period of time, because it is actually the same image stretched for a longer period of time to cover up the blur. This is called the "stopped-clock illusion", when the first second on a clock after you turn to look at it appears to take longer than all the other seconds.

The new technology developed by a team of scientists from the Laboratory for complex flow and heat transfer from the Institute of Technology in Harbin, made it easier for submarines and torpedoes to move under water extremely high speeds, according to the portal.
Lifang Chen, professor of mechanics and engineering fluid, said the innovative approach of this team, caused that they can now create complicated air "bubble" necessary to move quickly under water.
"We are very excited about the potential that it brings" he said, adding that there are still many unknowns to be solved.
Water causes more friction and resistance to movement than air, which means that ordinary submarines can not move as fast as an airplane, according to the portal.
Recalls that during the Cold War, the Soviet military developed a technology called super-cavitation, which included a "package" submarine inside air bubbles to avoid problems caused by water resistance.

The Soviet super-cavitation torpedo called Šakval able to reach the speed of 370 km / h or more, which was much faster than any ordinary torpedo.
In theory, the super-cavitational vessel could, under the water reaches the speed of sound, or about 5,800 km / h, which, according to the report of California Institute of Technology in 2001, could lead to reduced travel time from one to the other shore of the Atlantic Ocean to less than hour, while traveling from one to the other shore of the Pacific ocean took about a hundred minutes.
This is for now only in theory, scientists are skeptical of the practice.
In addition to Russia, the development of vessels and weapons based on super-cavitation technology deal with countries like Germany, Iran and the United States, according to the portal.
