NASA launched the BOLT-II mission for researching hypersonic flight




The fact is that hypersonic systems are not always big. And they might seem very much about the normal rockets. Hypersonic aerial vehicles can also use conventional rocket engines for reaching hypersonic speed. The BOLT-II is hoped to collect information about the world. That is beyond the supersonic world.  Hypersonic aircraft need new ideas for making operations secure. 

There is a small metal profile in the rocket. And that profile tests what shape is right for a larger hypersonic vehicle. In image 2 you can see how small the BOLT-II is. And there is also an image of that profile that is used as an aerodynamic test unit in that mission.

Hypersonic flight causes extreme stress on the aerodynamic control levels. And that's why the problem is how to turn the hypersonic vehicle during its flight in the atmosphere. The solution is how to change the course of the hypersonic vehicle can be the air channel that travels through the aircraft. There are branches in that tube. That begins at the nose of the hypersonic vehicle. 

The ventilation will aim the airflow to the right branch. And that turns the vehicle. The BOLT-II that is launched from Wallops Island. Is a demonstration that hypersonic vehicles are not necessarily large. Even fighter aircraft can carry small-size hypersonic vehicles. Those vehicles can carry small satellites to suborbital or ballistic trajectories. 

Or they can use as missiles. Those small-size hypersonic missiles are effective, especially against ships. But as you know those systems are multi-use. And they can use in many different missions in peace and war. And hypersonic technology is a new and interesting area in aviation.

Thoughts about the movie "Sphere"






http://kimmontaidearvioita.blogspot.com/p/thoughts-about-movie-sphere.html

"Sphere" is one of the most interesting SciFi-movies, what I have ever seen, and it is the tale of the thing, what comes from tomorrow, and makes all wishes to become true. This is the very good tale to make the nice little movie, but there is one other explanation, what could make those fictional cases, what happened in that movie. In the movie, those scientists face their worst nightmares, and near the end, they rise from the bottom of the sea to empty ship, where they wish that the mysterious "sphere" would leave the Earth.


This movie could also tell about government test, where those scientists would be connected with together by using EEG-machines, and the computer would deliver their thoughts to every member of the team by using brain core stimulation. This kind of fictional test would be made for creating the system, what is connecting human brains straight to computers. And one thing, what those computer specialists must make, is the filter, what cuts off the nightmares from that system.



So in this version, those scientists would be given anesthesia, and then their brains would be connected to the computers. If the system could not filter the fears, they would be delivered to every member of the team, and that would cause the ultimate Virtual Reality experience. If this kind of test would be done in the deep sea, it can be fully controlled. Every information, what is collected will travel thru the Navy, and nothing can be published without permission of the naval officers.


In this fictional test, those scientists can be put in the sleep in the midget submarine by using nitrous oxide, and they would ever be seen, that those people were in some kind of tests. So this kind of thoughts that movie brought in my mind. If we someday will put our brains straight connection with computers, we would make the ultimate computer, what can also create new things. The major problem with the computers is that they cannot make anything new, and they would not have any kind of imagination.


That's why computer's movements on the chessboard and other computer games are very well predictable, what is their biggest weakness. The human would win the computer in most computer games after a couple of training games because the gamer starts to remember the corners, where the opponent is coming. And this thing makes possible to win the computer, and play the game thru. In the same way, the gamer starts to remember the game areas in some action games, and this makes the person, who have tested those paintball tracks before very effective.


Technically we need only EEG-machine, decoder, and the electric shock equipment, what would make the brain core stimulation and allows two ways of communication between human and computer. And if we sometimes would make that machine, we can make the computer, what is so intelligent as we want. We can, in theory, connect even all mankind to supercomputers, but there would be many ethical and moral problems with that kind of advantage. Technology is the very interesting thing, and it would not always follow the moral or even the law.

The story about lost cosmonauts still lives on

https://www.facebook.com/thevintagenews/posts/1962607353814369

Kimmo Huosionmaa

When we are thinking of early years of space flights, we must say that no engineering work comes from nowhere. There must make work with those vehicles, and then there would happen some mistakes with them. And those mistakes confesses, that engineers made their best, and all tests were done. NASA has been dared to show those mistakes, and that might save the lives of American astronauts.


There were actually some secrets in the space capsules, what was not told to the public audience. One was that in some cases are the capsules used inertial navigation system or they were remote controlled, and somebody claims that none astronauts ever made any maneuvers by Mercury or Vostok-capsules. But when we are thinking about the lost astronauts or cosmonauts, we must say that there might be something, what is not told to people. Until NASA:s shuttle orbiter and the cases, when that space plane was used to launch secret military satellites, would the public audience noticed that there were some secret space missions.


There have been found some objects, what looks like skulls from Mars, and somebody has thought that maybe those strange objects were monkeys, what send to Mars for returning test, and then the carbon dioxide pocket have been collapsed and the spacecraft would be destroyed. In this theory, those habitats were sent to there without official permission, and then the permission denied. When we are talking about strange stories about malfunctions of Alexey Leonov space suit during his first spacewalk during spacewalk in Voskhod 2 flight, we must think that those technical problems support the theory, that maybe some cosmonauts were killed, when their space suits or capsules pressure was dropped to zero, or burned into the atmosphere.


I think that this kind of accidents was kept secret from other cosmonauts. Maybe those lost cosmonauts were served in secret space missions, where they flew some secret space recon planes, like "Vostok-type recon satellites", what mission would be targeted and follow the nuclear strikes. Maybe those manned satellites saw use in the early 1960's. When we are thinking about the political atmosphere in the Soviet Union during the Vostok-program, we must say that maybe Yuri Gagarin, was not the first man in the space. That would give the Soviet authorities possibility to close that hero's mouth. The Soviet authorities might not tell that thing to Gagarin, who really believed, that he was the first man in the space.


Maybe his death during the routine flight was suicide because somebody mentioned him about that failed man. There are many rumors about secret space flights to the moon, and if those missions were not made exactly right, can those spacecraft lost in space. And if the spacecraft would miss the orbiter of the Moon, it would go straight to outer space without the opportunity to return. But without evidence, this text is pure fiction. Nothing more.
