(CBS/AP) North Korea's much-anticipated rocket launch ended quickly in failure early Friday, splintering into pieces over the Yellow Sea soon after takeoff.
North Korea acknowledged in an announcement broadcast on state TV that a satellite launched hours earlier from the west coast failed to enter into orbit. The U.S. and South Korea also declared the launch a failure.
The Kwangmyongsong-3 satellite was fired from the Sohae Satellite Launching Station in Tongchang-ri along the west coast at 7:38 a.m., but failed to reach orbit, the state-run Korean Central News Agency said.
"Scientists, technicians and experts are now looking into the cause of the failure," KCNA said.
South Korea's foreign minister Kim Sung-hwan provided no further details about what he said was the North's failure to launch a rocket the West has condemned as a cover for a missile test.
He told reporters Friday in a nationally televised address that Seoul is "strongly condemning North Korea's new leadership" for ignoring international warnings to cancel the launch.
Meanwhile, North American Aerospace Defense Command officials say the U.S. detected and tracked the launch of the North Korean missile at 6:39 p.m. EDT. NORAD says the missile went south over the Yellow Sea about 165 kilometers west of Seoul. Stages two and three failed and no debris fell on land.
NORAD says the missile and the debris were never a threat.
South Korean and U.S. officials earlier said North Korea fired a long-range rocket. That was in defiance of international warnings against moving forward with a launch widely seen as a provocation.
The White House Office of the Press Secretary issued a statement, which said: "Despite the failure of its attempted missile launch, North Korea's provocative action threatens regional security, violates international law and contravenes its own recent commitments. While this action is not surprising given North Korea's pattern of aggressive behavior, any missile activity by North Korea is of concern to the international community. The United States remains vigilant in the face of North Korean provocations, and is fully committed to the security our allies in the region."
In response to the launch, Washington announced it was suspending plans to contribute food aid to the North in exchange for a rollback of its nuclear programs.
Space officials had announced they would launch a satellite this week as part of celebrations honoring North Korea founder Kim Il Sung, and liftoff took place at 7:39 a.m. from the west coast launch pad in the hamlet of Tongchang-ri, South Korea's Joint Chiefs of Staff in Seoul said, citing South Korean and U.S. intelligence.
However, the launch had appeared to have failed, with the rocket splintering into pieces moments after takeoff, South Korea's Defense Ministry said in Seoul.
"We suspect the North Korean missile has fallen as it divided into pieces minutes after liftoff," Defense Ministry spokesman Kim Min-seok told reporters.
In Washington, a U.S. official also said the launch appeared to have failed. The official offered no further details and would not discuss the source of the information.
Tokyo, which was prepared to shoot down any rocket flying over its territory, also confirmed a launch from North Korea.
"We have confirmed that a certain flying object has been launched and fell after flying for just over a minute," Japan's Defense Minister Naoki Tanaka said. He said there was no impact on Japanese territory.
"For all their advanced technology, these rockets are fairly fragile things," said Brian Weeden, a technical adviser at Secure World Foundation who is a former Air Force officer at the U.S. Space Command. "You're looking at a metal cylinder that has fairly thin walls that contains a lot of high pressure liquid."
North Korea had earlier announced it would send a three-stage rocket mounted with a satellite as part of celebrations honoring late President Kim Il Sung, whose 100th birthday is being celebrated Sunday.
A failure would be a huge blow to a nation that has staked its pride on a satellite launch seen as a show of strength amid persistent economic hardship as North Korea's young new leader, Kim Jong Un, solidifies power following the death of his father, longtime leader Kim Jong Il, four months ago.
North Korean space officials said the Unha-3 rocket is meant to send a satellite into orbit to study crops and weather patterns -- its third bid to launch a satellite since 1998. Officials took foreign journalists to the west coast site to see the rocket and the Kwangmyongsong-3 satellite Sunday in a bid to show its transparency amid accusations of defiance.
The United States, Britain, Japan and others have called such a launch a violation of U.N. resolutions prohibiting North Korea from nuclear and ballistic missile activity.
Experts say the Unha-3 carrier is the same type of rocket that would be used to launch a long-range missile aimed at the U.S. and other targets. North Korea has tested two atomic devices but is not believed to have mastered the technology needed to mount a nuclear warhead on a long-range missile.
U.S. Secretary of State Hillary Rodham Clinton, speaking for the Group of Eight nations after their foreign ministers met in Washington, said Thursday that all the members of the bloc agreed to be prepared to take further action against North Korea in the Security Council if the launch went ahead.
"Pyongyang has a clear choice: It can pursue peace and reap the benefits of closer ties with the international community, including the United States; or it can continue to face pressure and isolation," Clinton said.
South Korean President Lee Myung-bak was convening an emergency security meeting, officials said.
Reuters reported that the U.N. Security Council will convene on Friday to discuss a response to the launch, according to council diplomats.
"The North Korea rocket launch is a clear provocation and a violation of U.N. Security Council Resolutions which prohibit this activity," Kap-soo Rim, First Secretary of the Republic of Korea Mission to the U.N., told CBS News.
"The Security Council should act decisively, and strongly," Rim said, "the Ambassador is waiting for instructions from Seoul."
CBS News foreign affairs analyst Pamela Falk said that the launch "is unlikely to provoke more than a statement of alarm from the U.N. in the short term, and perhaps more extensive sanctions in the long term, particularly since the launch failed."
According to projections, the first stage of the rocket was to fall into the ocean off the western coast of South Korea, while a second stage would fall into waters off the eastern coast of the Philippine island of Luzon.
Weeden said the launch appeared to be a failure of both space and missile objectives.
"The earlier it breaks up, the less data you've collected, so the less useful that test is likely to be," he said. "It's very likely that the U.S. and its allies probably gathered more information about this test than the North Koreans have."
He said U.S. and other nations had been poised to keep close watch on the launch to gather intelligence about the state of North Korea's rocket program.
