North Korea’s recently launched satellite has achieved stable orbit but not yet transmitted data back to Earth, US sources said of a launch that has so far failed to convince experts that Pyongyang has significantly advanced its rocket technology.
Sunday’s launch of what North Korea said was an earth observation satellite angered the country’s neighbors and the United States, which called it a ballistic missile test. It followed Pyongyang’s fourth nuclear test in January.
“It’s in a stable orbit now. They got the tumbling under control,” a US official said on Tuesday.

That is unlike the North’s previous satellite, launched in 2012, which never stabilized, the official said. However, the new satellite is not believed to be transmitting, another source added. US President Barack Obama spoke with the leaders of South Korea and Japan by phone on Monday night and reassured them of Washington’s support, while also calling for a strong international response to the launch, the White House said.
The United States and China, Pyongyang’s only major ally, are negotiating the outline of a new UN sanctions resolution that diplomats hope will be adopted this month.
The UN Security Council has imposed sanctions against North Korea for its nuclear tests and long-range rocket launches dating back to 2006, banning arms trade and money flow that can fund the country’s arms programme.
But a confidential UN report concluded that North Korea continues to export ballistic-missile technology to the Middle East and ship arms and materiel to Africa in violation of UN restrictions.
The report by the UN Security Council’s Panel of Experts on North Korea, which monitors implementation of sanctions, said there were “serious questions about the efficacy of the current United Nations sanctions regime”.
Western diplomats told Reuters that restricting North Korean access to international ports is among the measures Washington is pushing Beijing to accept in the wake of the Jan. 6 nuclear test and the weekend rocket launch.
YEARS AWAY FROM NUCLEAR MISSILE
Missile experts say North Korea appears to have repeated its earlier success in putting an object into space, rather than broken new ground. It used a nearly identical design to the 2012 launch and is probably years away from building a long-range nuclear missile, the experts said.
The rocket was based on engines taken from its massive stockpile of mid-range missiles based on Soviet-era technology and electrical parts too rudimentary to be targeted by a global missile control regime, they added.
“I suspect the aim of the launch was to repeat the success, which itself provides considerable engineering knowledge,” said Michael Elleman, a missile expert at the International Institute for Strategic Studies.
South Korea’s defense ministry believes the three-stage rocket, named Kwangmyongsong, had a potential range of 12,000 km (7,457 miles), Yonhap news agency reported, similar to that of the 2012 rocket and putting the US mainland in reach.
Some experts, though, believe the North is a decade or more from using what it learns from its space launch vehicles to building an inter-continental ballistic missile capable of threatening the US west coast. Separately, US National Intelligence Director James Clapper said on Tuesday that North Korea could begin to recover plutonium from a restarted nuclear reactor within weeks.
Clapper said that in 2013, following its third nuclear test, the North had announced its intention to “refurbish and restart” facilities at its Yongbyon nuclear complex.
“We assess that North Korea has followed through on its announcement by expanding its Yongbyon enrichment facility and restarting the plutonium production reactor,” Clapper said in prepared testimony to the Senate Armed Services Committee.
“We further assess that North Korea has been operating the reactor long enough so that it could begin to recover plutonium from the reactor’s spent fuel within a matter of weeks to months,” he said in his annual Worldwide Threat Assessment.
