North Korea has carried out activities in rocket triggered uproar in the international community. Although North Korea claims that the success of its launch, "Star Light II" satellite successfully into orbit, but the United States, Japan and South Korea have said publicly that North Korea did not find the satellite in orbit and did not receive the satellite signal launched by North Korea to launch Second, with three booster rocket crashed into the Pacific Ocean to prove that the failure to launch.
Analysts pointed out that although North Korea's launch activities in the technical and did not meet the desired results, but the rocket's flight path to prove North Korea's rocket technology is indeed made progress, but also from a political perspective, the activities of North Korea's launch of its purpose.
Shot farther irksome
Launch activities in North Korea shortly after the Korean Central News Agency announced that North Korea make use of carrier rockets, "Galaxy II" satellite successfully "Light Star II" into orbit, the satellite in orbit exclusive normal rotation, and issued revolutionary hymn "Song of General Kim Il Sung." However, close monitoring of North Korea launched the United States, Japan, Korea and other countries believe that North Korea did not the satellite put into orbit.
North Korea is responsible for tracking the activities of the U.S. military launched the North American Aerospace Defense Command announced briefing pointed out that North Korea first-class booster rocket crashed into the Sea of Japan, with boosters and other objects into the North Pacific Ocean, carrying objects weighing about 30 kilograms . The command also said that any objects have not been able to launch into orbit, and any debris did not fall on Japanese territory.
Briefing also said that the rockets in North America and Hawaii do not pose a threat, it did not take any measures. This means that the second and third-stage rocket to fall at the same time, this two-stage separation of the rocket did not succeed.
But the outside world that despite North Korea's launch activities does not prove successful, but still showed North Korea's rocket technology has made progress.
North Korea in August 1998 and July 2006 has been launched with significant activity indicators.
At that time, North Korea declared in 1998 launched a "One Star Light," but is widely believed that the launch of "-1 Taepodong" missile. At that time, the launch is the first and second levels the normal operation of the booster rocket, but the third-stage rocket crashed. The first level and second stage rocket from the launch site at 250 kilometers and 1646 kilometers of the local fall.
Launched in 2006 is "-2 Taepodong" missile, but missiles fired more than 40 seconds after the explosion.
Korean Central Television Station the evening of April 7 launch on the 5th event broadcast live images. This is an integrated command post at the scene to control the screen. It is worth noting that there is no space measurement as a result of the Korean fleet, do not have to carry out rocket and satellite to monitor the ability of the whole accurate, only the first section of the launch track.
In the April 5 launch, the United States and South Korea intelligence agencies believe that North Korea's first-class and second-class booster rocket from the launch site in more than five hundred kilometers and 3200 kilometers of the Japan Sea and North Pacific waters fall. If the rockets into ballistic missiles, when compared to 1998, extended the range of more than 1 times.
Japan's "Sankei Shimbun" analysis that shows that North Korea launched the technology progress, spend seven minutes to reach the Japanese archipelago over the display of flight time to maintain the normal speed of the missile and the missile first stage boosters have the greatest impetus R & D is the most important part of the success of the separation of great significance.
Maxwell Air Force Base in the United States Institute of Aeronautics and Astronautics Professor that if the upgrade its military capabilities from the point of view, North Korea's launch last weekend was a success. Sheldon said: "If we say that the real purpose of North Korea is developing long-range ballistic missiles rather than the satellite into orbit, then the launch is successful. This is the North Korean ballistic missiles fired from the longest to show North Korea has in the near term and long-term ability to increase the range of ballistic missiles. "
Former U.S. Department of Defense analysis and evaluation of the project director that although North Korea is not able to vector into space, but obviously the rocket launcher caused great concern in the U.S. military, from this sense, North Korea's attempt to is successful.
Rocket separation may be wrong
North Korea prior to launch to the International Maritime Organization, issued a circular, saying the first-class booster rocket will fall away from North Hamgyong County flower bed Musudan-ri test site 650 kilometers far from the sea of Japan, the second-class booster rocket will fall 3600 kilometers away in the North Pacific Ocean. North Korea fired an exception in advance public information, the international community believes that North Korea's rocket technology to a very strong confidence.
However, the United States and Japan and other countries to judge the intelligence services believed that the first and second levels of the falling booster rocket failed to achieve the desired location of the distance. Hankuk Aviation University, Professor Zhang Yong-kan pointed out that this can be regarded as not at all normal combustion rocket.
Korea Aerospace Research Institute of emission to the Minister Zhao said that if North Korea is to announce in advance the circumstances in accordance with the design of emission, it can be regarded as a rocket combustion problem. In short, the situation is not the engine combustion to achieve the desired extent, it can not be third-class booster rocket to high ideals.
However, the United States, Japan and South Korea and Russia and other countries are using their massive space complete monitoring of the activities of North Korea's launch of the full monitoring, through data collection, satellite picture of North Korea were to show up.
Is generally believed that the third level is the role of the booster rocket, which will ultimately put into orbit satellites or ground-based ballistic missiles pointing direction. Whether it is because the first and second levels of the booster rocket propulsion inadequate, or because the existence of third-class booster rocket problem itself can be said that North Korea failed to successfully launch the show can be converted into the possibility of ballistic missile . In particular, it is doubtful that two or three booster separation may not fall together, This shows that North Korea launched a ballistic missile and satellite technology - Step-Rockets separation technology, there are still shortcomings.
There are experts believe that North Korea launched a rocket carrying the same day weight is about 30 kilograms, more than 3200 km of flight, but if the use of the weight reached 500-1000 kg warhead, is bound to further reduce the range. Intercontinental ballistic missiles flying at least 5500 kilometers, so the Korean intercontinental ballistic missile technology is not yet ripe.
North Korea even if the satellite successfully placed in orbit, in the case of intercontinental ballistic missiles, warheads also need to enter the atmosphere, then must be resistant to ultra-high temperature technology. But North Korea is to master the technology, at present still unclear. - 22787
