North Korea Satellite & Rocket Launch Failed

DPRK confirms satellite failed to enter orbit




Pyongyang, April 13 (Xinhua) -- An earth observation satellite launched by the Democratic People's Republic of Korea (DPRK) earlier Friday morning has failed to enter orbit, and scientists and technicians are now looking into the cause of the failure, the official KCNA news agency reported.

The Kwangmyongsong-3 satellite was launched at the Sohae Satellite Launching Station in Cholsan County, North Phyongan Province at 07:38 a.m. on Friday (2238 GMT Thursday), said the report.

"The earth observation satellite failed to enter its preset orbit.Scientists, technicians and experts are now looking into the cause of the failure," it said.

The DPRK's failed launch has aroused international concerns, with the United States, Japan and South Korea all condemning the move, which they viewed had breached relevant UN resolutions.

The DPRK has said that its launch is for peaceful purposes and would not harm the region and neighboring countries.

North Korea has launched its long-range rocket but the US, Japan and South Korea say it failed shortly after take-off and fell into the sea. There has been no word yet from Pyongyang on the launch. 

North Korea says the aim of the rocket is to launch a satellite but critics say the launch constituted a disguised test of long-range missile technology banned under UN resolutions.

As the world watches and waits to see if North Korea will continue in its bid to launch a long-range rocket despite international warnings, a new video animation reveals just how the space test could occur.

The new video, released late Wednesday (April 11) by the analytical firm Analytical Graphics Inc., covers North Korea's planned Unha-3 rocket launch, showing the flight trajectory from a point just after liftoff through the separation of its satellite payload.


"AGI has used its software to produce a video demonstrating the launch and its possible path, tracking assets and landing zones," AGI officials wrote in a media alert.

North Korean space officials have said the Unha-3 rocket will launch a new Earth-observing satellite sometime between April 12 and April 16 to honor the 100th anniversary of the birth of Kim Il Sung, the founder of North Korea.

According to AGI's video animation of the Unha-3 rocket launch, the three-stage booster will blast off from the new North Korean launch site near the northwest village of Tongchang-ri, which corresponds with official statements from North Korea and Western observers. The rocket will then head in a southerly direction and drop its first stage in the Yellow Sea well to the west of South Korea, where officials have said they would shoot down any parts of the Unha-3 territory that threatened to fall on South Korean territory.

The next stage of the Unha-3 rocket would likely fall just to the east of the Philippines after the booster's third stage and payload — the Earth-monitoring satellite Kwangmyongsong-3 — separates and heads towards orbit, the AGI animation shows.

If the Kwangmyongsong-3 satellite reaches its intended polar orbit, its trajectory would carry it over a major stretch of Australia after the spacecraft separates from the Unha-3 rocket, according to the AGI depiction.

North Korea's Unha-3 rocket appears to be a liquid-fueled rocket that stands about 100 feet (30 meters) tall. The Kwangmyongsong-3 satellite, meanwhile, is a boxy, solar-powered spacecraft, according to videos and images in media reports, as well as the AGI video.

Exactly which day of the current window North Korea will launch the Unha-3 rocket is not yet certain, though the country's space organization did begin fueling the rocket for liftoff on Wednesday, suggesting a potential launch attempt in upcoming days, according to press reports.
