U.S. flies F-22 fighters over South Korea after North’s rocket launch

OSAN, South Korea (Reuters) – The United States flew four F-22 stealth fighter jets over South Korea on Wednesday in a show of force following North Korea’s recent rocket launch and ahead of the allies’ joint military drills next month aimed at deterring Pyongyang’s threat.

The flight of the radar-evading F-22s, based in Okinawa, Japan, is the latest deployment of key U.S. strategic military assets to the South after the North defied warnings from world powers and conducted a fourth nuclear test last month.

South Korea and the United States said the North’s rocket launch on Feb. 7 was a long-range missile test and violated U.N. Security Council resolutions that ban the use of ballistic missile technology by the isolated state.

North Korea said it was a satellite launch.

The U.S. military said at the weekend that it had deployed an additional Patriot high-velocity missile interceptor unit to South Korea in response to recent North Korean provocations.

The allies were also expected to begin discussions on the deployment of the advanced Terminal High Altitude Area Defense (THAAD) missile defense system.

Last month, the United States flew a B-52 bomber capable of carrying nuclear weapons on a low-level flight over the South following the North’s Jan. 6 nuclear test.

The joint military drills scheduled to start in March, which in most years last eight weeks and involve hundreds of thousands of South Korean and U.S. troops, will be the largest ever, according to South Korean officials.

There are 28,500 U.S. troops stationed in the South as part of combined defense with the South’s military of more than 600,000. The North has an army of 1.2 million.

North Korea claims the annual drills are war preparations. South Korea and the United States say the exercises, which have been conducted for years without major incident, are defensive.

Though North Korea satellite not transmitting, rocket payload a concern

WASHINGTON (Reuters) – A satellite put into orbit by North Korea at the weekend does not appear to be transmitting, but it is worrying that the rocket that took it there delivered twice the payload of Pyongyang’s previous launch, the head of the U.S. Army’s Missile Defense Command said on Wednesday.

“If you look at the previous launch and the payload it put into orbit … just the increase in weight is I think an important factor,” Lieutenant-General David Mann told a seminar on Capitol Hill organized by the Hudson Institute think tank.

“Whenever you are able to put something into orbit, that’s significant,” Mann said.

“I don’t think it’s transmitting as we speak, but it does reflect a capability that North Korea is trying to leverage in terms of its missile technologies,” he said.

“That kind of capability and then also the collateral usages for that technology are obviously very, very concerning to nations around the world in terms of ICBM (Intercontinental Ballistic Missile) capabilities.”

Mann said the payload carried was almost twice as large as that carried in North Korea’s previous satellite launch in 2012.

He did not give a figure for the weight of the latest satellite, but South Korean officials have put it at 440 pounds.

Sunday’s launch, which followed Pyongyang’s fourth nuclear bomb test on Jan. 6, was condemned by the United States and countries around the world, which believe it was cover for development of ballistic missile technology.

The United States and South Korea immediately said they would begin formal talks about deploying the sophisticated U.S. Terminal High Altitude Area Defense system, or THAAD, to the Korean peninsula “at the earliest possible date.”

South Korea had in the past been reluctant to begin formal talks on the Lockheed Martin Corp missile defense system due to worries about upsetting China, its biggest trading partner, which believes it could reduce the effectiveness of its strategic deterrent.

Asked when THAAD might go to South Korea, Mann said there was no timeline for a possible deployment, but added: “I think both governments are going to begin conversations looking at the feasibility of THAAD and we will see what happens from there.”

On Wednesday, Russia’s Foreign Ministry said U.S. plans to for a missile shield in South Korea could trigger an arms race in Northeast Asia.

North Korea satellite in stable orbit but not transmitting, U.S. sources say

WASHINGTON (Reuters) – North Korea’s recently launched satellite has achieved stable orbit but is not believed to have transmitted data back to Earth, U.S. 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 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 U.S. 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 was not thought to be transmitting, another source added.

U.S. 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.

Obama will also address North Korea’s “provocations” when he hosts the leaders of the Association of Southeast Asian Nations in California early next week, aides said.

The United States and China, Pyongyang’s only major ally, are negotiating the outline of a new U.N. sanctions resolution that diplomats hope will be adopted this month.

The U.N. 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 program.

But a confidential U.N. report, seen by Reuters, concluded that North Korea continues to export ballistic-missile technology to the Middle East and ship arms and materiel to Africa in violation of U.N. restrictions.

The report by the U.N. 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.

“PROVOCATIVE, DISTURBING AND ALARMING”

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.

Vice Admiral James Syring, director of the U.S. Missile Defense Agency, told reporters that North Korea’s launch was “provocative, disturbing and alarming,” but could not be equated with a test of an intercontinental ballistic missile.

He said North Korea had never attempted to flight test the KN-08 intercontinental ballistic missile it is developing.

Syring said U.S. missile defenses would be able to defend against the new North Korean missile given efforts to improve the reliability of the U.S. system and increase in the number of ground-based U.S. interceptors from 30 to 44.

“I’m very confident that we’re, one, ahead of it today, and that the funded improvements will keep us ahead of … where it may be by 2020,” he said.

The latest North Korea 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, experts said.

South Korea’s defense ministry believes the three-stage rocket, named Kwangmyongsong, had a potential range of 7,457 miles, Yonhap news agency reported, similar to that of the 2012 rocket and putting the U.S. mainland in reach.

“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.

Separately, U.S. 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.

North Korea rocket launch may spur U.S. missile defense buildup in Asia

WASHINGTON (Reuters) – North Korea’s latest rocket launch might kick off a buildup of U.S. missile defense systems in Asia, U.S. officials and missile defense experts said, something that could further strain U.S.-China ties and also hurt relations between Beijing and Seoul.

North Korea says it put a satellite into orbit on Sunday, but the United States and its allies see the launch as cover for Pyongyang’s development of ballistic missile technology that could be used to deliver a nuclear weapon.

Washington sought to reassure its allies South Korea and Japan of its commitment to their defense after the launch, which followed a North Korean nuclear test on Jan. 6.

The United States and South Korea said they would begin formal talks about deploying the sophisticated Terminal High Altitude Area Defense system, or THAAD, to the Korean peninsula “at the earliest possible date.”

South Korea had been reluctant to publicly discuss the possibility due to worries about upsetting China, its biggest trading partner.

Beijing, at odds with the United States over Washington’s reaction to its building of artificial islands in the disputed South China Sea, quickly expressed “deep concern” about a system whose radar could penetrate Chinese territory.

China had made its position clear to Seoul and Washington, the Foreign Ministry said.

“When pursuing its own security, one country should not impair others’ security interests,” spokeswoman Hua Chunying said in a statement.

TIPPING POINT

But the North Korean rocket launch, on top of last month’s nuclear test, could be a “tipping point” for South Korea and win over parts of Seoul’s political establishment that remain wary of such a move, a U.S. official said.

South Korea and the United States said that if THAAD was deployed to South Korea, it would be focused only on North Korea.

An editorial in the Global Times, an influential tabloid published by the ruling Chinese Communist Party’s official People’s Daily newspaper, called that assurance “feeble”.

“It is widely believed by military experts that once THAAD is installed, Chinese missiles will be included as its target of surveillance, which will jeopardize Chinese national security,” it said.

Japan, long concerned about North Korea’s ballistic missile program, has previously said it was considering THAAD to beef up its defenses. The North Korean rocket on Sunday flew over Japan’s southern Okinawa prefecture.

Chief cabinet secretary Yoshihide Suga told reporters on Monday the Defense Ministry had no concrete plan to introduce THAAD, but added the ministry believed new military assets would strengthen the country’s capabilities.

Riki Ellison, founder of the Missile Defense Advocacy Alliance, said the launch would give Japan momentum to deploy THAAD.

Washington moved one of its five THAAD systems to Guam in 2013 following North Korean threats, and is now studying the possibility of converting a Hawaii test site for a land-based version of the shipboard Aegis missile defense system into a combat-ready facility.

EFFECTIVENESS QUESTIONED

Some experts questioned how effective THAAD would be against the type of long-range rocket launched by North Korea and the Pentagon concedes it has yet to be tested against such a device.

THAAD is designed to intercept and destroy ballistic missiles inside or just outside the atmosphere during their final, or terminal, phase of flight. It has so far proven effective against short- and medium-range ballistic missiles.

John Schilling, a contributor to the Washington-based 38 North project that monitors North Korea, said THAAD’s advanced AN/TPY-2 tracking radar built by Raytheon Co could provide an early, precise track on any such missile.

David Wright, co-director of the Global Security Program at the U.S.-based Union of Concerned Scientists, said that while THAAD could not shoot down the type of rocket launched on Sunday its deployment could reassure the South Korean public.

“Much of what missile defense programs are about is reassuring allies and the public,” he said.

SUITABLE SITE IDENTIFIED

One U.S. official said the North Korean launch added urgency to longstanding informal discussions about a possible THAAD deployment to South Korea. “Speed is the priority,” said the official, who asked not to be named ahead of a formal decision.

Renewed missile-defense discussions with the United States could also send a message to Beijing that it needs to do more to rein in North Korea’s ballistic missile and nuclear weapons programs, another U.S. official said.

South Korean officials have already identified a suitable site for the system, but it could also be placed at a U.S. base on the Korean peninsula, Ellison said.

THAAD is a system built by Lockheed Martin Corp that can be transported by air, sea or land. The Pentagon has ordered two more batteries from Lockheed.

One of the four THAAD batteries based at Fort Bliss, Texas, is always ready for deployment overseas, and could be sent to Japan or South Korea within weeks, Ellison said.

Lockheed referred all questions about a possible THAAD deployment to the U.S. military.

North Korean rocket puts object into space, angers neighbors, U.S.

SEOUL/UNITED NATIONS (Reuters) – North Korea launched a long-range rocket carrying what it called a satellite, drawing renewed international condemnation just weeks after it carried out a nuclear bomb test.

Critics of the rocket program say it is being used to test technology for a long-range missile.

South Korea and the United States said they would explore whether to deploy an advanced missile defense system in South Korea “at the earliest possible date.”

The U.S. Strategic Command said it had detected a missile entering space, and South Korea’s military said the rocket had put an object into orbit.

North Korea said the launch of the satellite Kwangmyongsong-4, named after late leader Kim Jong Il, was a “complete success” and it was making a polar orbit of Earth every 94 minutes. The launch order was given by his son, leader Kim Jong Un, who is believed to be 33 years old.

North Korea’s state news agency carried a still picture of a white rocket, which closely resembled a previously launched rocket, lifting off. Another showed Kim surrounded by cheering military officials at what appeared to be a command center.

Isolated North Korea’s last long-range rocket launch, in 2012, put what it called a communications satellite into orbit, but no signal has ever been detected from it.

“If it can communicate with the Kwangmyongsong-4, North Korea will learn about operating a satellite in space,” said David Wright, co-director and senior scientist at the Global Security Program of the Union of Concerned Scientists.

“Even if not, it gained experience with launching and learned more about the reliability of its rocket systems.”

The rocket lifted off at around 9:30 a.m. Seoul time (0030 GMT) on a southward trajectory, as planned. Japan’s Fuji Television Network showed a streak of light heading into the sky, taken from a camera at China’s border with North Korea.

North Korea had notified United Nations agencies that it planned to launch a rocket carrying an Earth observation satellite, triggering opposition from governments that see it as a long-range missile test.

The U.N. Security Council condemned the launch in an emergency meeting on Sunday, and vowed to take “significant measures” in response to Pyongyang’s violations of U.N. resolutions, Venezuela’s U.N. ambassador said.

U.S. Ambassador Samantha Power told reporters: “We will ensure that the Security Council imposes serious consequences. DPRK’s (North Korea) latest transgressions require our response to be even firmer.”

The United States and China began discussing a U.N. sanctions resolution after Pyongyang’s Jan. 6 atomic test.

North Korea had initially given a Feb. 8-25 time frame for the launch but on Saturday changed that to Feb. 7-14, apparently taking advantage of clear weather on Sunday.

North Korea’s National Aerospace Development Administration called the launch “an epochal event in developing the country’s science, technology, economy and defense capability by legitimately exercising the right to use space for independent and peaceful purposes”.

The launch and the nuclear test are seen as efforts by the North’s young leader to bolster his domestic legitimacy ahead of a ruling party congress in May, the first since 1980.

North Korea’s embassy in Moscow said in a statement the country would continue to launch rockets carrying satellites, according to Russia’s Interfax news agency.

NEW MISSILE DEFENSE?

South Korea and the United States said that if the advanced missile defense system called Terminal High Altitude Area Defence (THAAD) was deployed to South Korea, it would be focused only on North Korea.

Seoul had been reluctant to discuss openly the possibility of deploying THAAD. South Korean President Park Geun-hye termed Sunday’s launch an unforgivable act of provocation.

“North Korea continues to develop their nuclear weapons and ballistic missile programs, and it is the responsibility of our Alliance to maintain a strong defense against those threats,” General Curtis M. Scaparrotti, U.S. Forces Korea commander, said in a statement.

China, South Korea’s biggest trading partner, repeated what it says is “deep concern” about a system whose radar could penetrate its territory.

South Korea’s military said it would make annual military exercises with U.S. forces “the most cutting-edge and the biggest” this year. North Korea objects to the drills as a prelude to war by a United States it says is bent on toppling the Pyongyang government.

The United States has about 28,500 troops in South Korea.

U.S. Secretary of State John Kerry said the United States would work with the U.N. Security Council on “significant measures” to hold North Korea to account for what he called a flagrant violation of U.N. resolutions on North Korea’s use of ballistic missile technology.

Kerry held a telephone conversation with his South Korean and Japanese counterparts on Sunday, according to the State Department.

South Korea’s navy retrieved what it believes to be a fairing used to protect the satellite on its journey into a space, a sign that it is looking for parts of the discarded rocket for clues into the North’s rocket program, which it did following the previous launch.

China expressed regret over the launch and called on all sides to act cautiously to prevent any escalation. China is North Korea’s main ally, but it disapproves of its nuclear weapons program.

Russia, which has in recent years forged closer ties with North Korea, said the launch could only provoke a “decisive protest,” adding Pyongyang had once again demonstrated a disregard for norms of international law.

Russian Foreign Minister Sergei Lavrov discussed the launch with his Japanese counterpart, Fumio Kishida, the foreign ministry said later, with Japan initiating the phone call.

Russia stressed the importance of diplomacy in defusing the tension in northeast Asia during the call, the foreign ministry said in a statement.

NUCLEAR ASPIRATIONS

North Korea has been under U.N. sanctions since its first nuclear test in 2006. It has conducted three more atomic tests since then, including the one last month, along with numerous ballistic missile launches.

North Korea has said that last month’s nuclear test, its fourth, was of a hydrogen bomb. The United States and other governments have expressed doubt over that claim.

North Korea is believed to be working on miniaturizing a nuclear warhead to put on a missile, but many experts say it is some way from perfecting such technology.

It has shown off two versions of a ballistic missile resembling a type that could reach the U.S. West Coast, but there is no evidence the missiles have been tested.

U.S. and allies aim to track North Korean rocket launch

SEOUL/TOKYO (Reuters) – The United States has deployed missile defense systems that will work with the Japanese and South Korean militaries to track a rocket North Korea says it will launch some time over an 18-day period beginning Monday.

China, the North’s sole major ally but opposed to Pyongyang’s nuclear program, appealed for calm.

North Korea has notified U.N. agencies it will launch a rocket carrying what it called an earth observation satellite some time between Feb. 8 and Feb. 25, triggering international opposition from governments that see it as a long-range missile test.

North Korea says it has a sovereign right to pursue a space program. But it is barred under U.N. Security Council resolutions from using ballistic missile technology.

Coming so soon after North Korea’s fourth nuclear test, on Jan. 6, also barred by Security Council resolutions, a rocket launch would raise concern that it plans to fit nuclear warheads on its missiles, giving it the capability to strike South Korea, Japan and possibly the U.S. West Coast.

China has told North Korea that it does not want to see anything happen that could further raise tension, Chinese Foreign Minister Wang Yi said, describing “a serious situation”, after a special envoy from China visited North Korea this week.

The United States has urged China to use its influence to rein in its neighbor.

Speaking to President Park Geun-hye, Chinese President Xi Jinping said he hoped all parties could bear in mind the broader picture of maintaining peace and stability on the peninsula, and “calmly deal with the present situation”, China’s Foreign Ministry said.

“The peninsula cannot be nuclearized, and cannot have war or chaos,” Xi said, also repeating a call for dialogue.

Japan’s Asahi Shimbun newspaper quoted Pentagon officials as saying that fuelling of the rocket appeared to have begun. It cited satellite footage showing increased activity around the missile launch and fuel storage areas, suggesting preparations for a launch could be completed within “a number of days” at the earliest.

A launch would draw fresh U.S. calls for tougher U.N. sanctions that are already under discussion in response to the nuclear test.

What would likely be an indigenous three-stage rocket will be tracked closely. South Korea and Japan have put their militaries on standby to shoot down the rocket, or its parts, if they go off course and threaten to crash on their territory.

“We will, as we always do, watch carefully if there’s a launch, track the launch, (and) have our missile defense assets positioned and ready,” U.S. Defense Secretary Ashton Carter said on Thursday.

“We plan a lot about it. We and our close allies – the Japanese and the South Koreans – are ready for it.”

South Korea has said its Aegis destroyers, its Green Pine anti-ballistic missile radar and early warning and control aircraft Peace Eye are ready.

A U.S. Navy spokesman confirmed the missile tracking ship USNS Howard O. Lorenzen arrived in Japan this week but declined to say if it was in response to the North’s planned launch.

SEARCH FOR CLUES

Boosters and other parts will also be tracked as they splash into the sea, in the hope they can be retrieved and analyzed for clues on Pyongyang’s rocket program.

“Retrieving parts or objects from the launch vehicle are the most important part of the rocket analysis,” said Markus Schiller, a rocketry expert based in Germany.

North Korea said the launch would be during the morning and gave coordinates of where the boosters and payload cover would drop in the Yellow Sea off the Korean Peninsula’s west coast and the Pacific to the east of the Philippines.

The U.S. Navy has sonar equipment and unmanned vehicles that could be used to help recover parts, according to Navy officials. It was not clear if that equipment is in the region.

North Korea last launched a long-range rocket in December 2012, sending what it described as a communications satellite into orbit.

South Korea’s navy retrieved the section of the first stage booster that was part of the fuel tank and one of the four steering engines that confirmed the presence of technology and materials that North Korea had not been known to possess.

Analysis pointed to a launch vehicle capable of carrying a payload of about 500 kg (1,100 lb) more than 10,000 km (6,200 miles), according to South Korea.

A typical nuclear warhead weighs about 300 kg, although North Korea is not believed to have been able to miniaturize a nuclear weapon to that size.

Recovered parts allowed experts to conclude that the second stage booster likely used Soviet-era Scud missile technology and did not use advanced propellant, indicating the rocket was suited for satellite launch but unfit to deliver a warhead.

“My guess is that if you took the rocket they used last time and put a warhead on it you probably would not be able to reach the United States,” said David Wright, co-director and senior scientist at the Global Security Program of the Union of Concerned Scientists.

The search for information on the North’s rocket program will not be easy.

“Some of the more interesting parts, high-efficiency engines and guidance systems, are in the upper stages, and those usually fall far out to sea, at high speed into deep water,” said John Schilling, an aerospace engineer.

“Harder to find than that Malaysian airliner everybody has been looking for all last year.”

Pressure mounts on North Korea to abandon rocket launch

SEOUL/TOKYO (Reuters) – International pressure grew on North Korea to call off a planned rocket launch, seen by some governments as another missile test, while Japan put its military on alert to shoot down any rocket that threatens its territory.

North Korea notified United Nations agencies on Tuesday of its plan to launch what it called an “earth observation satellite” some time between Feb. 8 and 25.

Pyongyang has said it has a sovereign right to pursue a space program, although the United States and other governments suspect such rocket launches are tests of its missiles.

Japan’s defence minister, Gen Nakatani, told a media briefing on Wednesday he had issued an order to shoot down any “ballistic missile threat”.

Tension rose in East Asia last month after North Korea’s fourth nuclear test, this time of what it said was a hydrogen bomb.

A rocket launch coming so soon after would raise concern that North Korea plans to fit nuclear warheads on its missiles, giving it the capability to launch a strike against South Korea, Japan and possibly targets as far away as the U.S. West Coast.

North Korea last launched a long-range rocket in December 2012, sending an object it described as a communications satellite into orbit.

South Korea warned the North it would pay a “severe price” if it goes ahead with the launch.

“North Korea’s notice of the plan to launch a long-range missile, coming at a time when there is a discussion for (U.N.) Security Council sanctions on its fourth nuclear test, is a direct challenge to the international community,” the presidential Blue House said in a statement.

Russia’s Foreign Ministry said Pyongyang was demonstrating “an outrageous disregard for the universally recognised norms of international law,” while France said the launch would merit a firm response from the international community.

U.N. Secretary-General Ban Ki-moon urged North Korea not to use ballistic missile technology, which is banned by Security Council resolutions.

‘EXTREMELY CONCERNED’

China, under U.S. pressure to use its influence to rein in the isolated North, said Pyongyang’s right to space exploration was restricted under U.N. resolutions.

China is North Korea’s sole main ally, though Beijing disapproves of its nuclear programme.

“We are extremely concerned about this,” Chinese Foreign Ministry spokesman Lu Kang told a briefing on Wednesday.

“In the present situation, we hope North Korea exercises restraint on the issue of launching satellites, acts cautiously and does not take any escalatory steps that may further raise tensions on the Korean peninsula.”

Reports of the planned launch also drew fresh U.S. calls for tougher U.N. sanctions that are already under discussion in response to North Korea’s Jan. 6 nuclear test.

A spokeswoman for the International Maritime Organization, a U.N. agency, said it had been told by North Korea of the plan to launch a satellite.

The Washington-based North Korean monitoring project 38 North said commercial satellite images of North Korea’s Sohae launch site taken on Monday showed activity consistent with preparations for a launch within North Korea’s given timeframe, but no indications that this was imminent.

North Korea said the launch would be conducted in the morning one day during the announced period, and gave the coordinates for the locations where the rocket boosters and the cover for the payload would drop.

Those locations are expected to be in the Yellow Sea off the Korean Peninsula’s west coast and in the Pacific Ocean to the east of the Philippines, Pyongyang said.

South Korea told commercial airliners to avoid flying in areas of the rocket’s possible flight path during the period.

North Korea tells U.N. agencies it plans satellite launch

SEOUL/WASHINGTON (Reuters) – North Korea told U.N. agencies on Tuesday it plans to launch a satellite as early as next week, a move that could advance the country’s long-range missile technology after its fourth nuclear test on Jan. 6.

News of the planned launch between Feb. 8 and Feb. 25 drew fresh U.S. calls for tougher U.N. sanctions already under discussion in response to North Korea’s nuclear test. State Department spokesman John Kirby said the United Nations needed to “send the North Koreans a swift, firm message.”

Pyongyang has said it has a sovereign right to pursue a space program by launching rockets, although the United States and other governments worry that such launches are missile tests in disguise.

“We have received information from DPRK regarding the launch of earth observation satellite ‘Kwangmyongsong’ between 8-25 February,” a spokeswoman for the International Maritime Organization, a U.N. agency, told Reuters by email.

The International Telecommunication Union, another U.N. agency, told Reuters North Korea had informed it on Tuesday of plans to launch a satellite with a functional duration of four years, in a non-geostationary orbit.

It said the information provided by North Korea, whose official name is the Democratic People’s Republic of Korea, was incomplete, and that it was seeking more details.

U.S. officials said last week that North Korea was believed to be making preparations for a test launch of a long-range rocket, after activity at its test site was observed by satellite.

The White House said on Tuesday that any satellite launch by North Korea would be viewed as “another destabilizing provocation.” U.S. Assistant Secretary of State Daniel Russel, the senior U.S. diplomat for East Asia, told reporters it “argues even more strongly” for tougher U.N. sanctions.

Russel said a launch, “using ballistic missile technology,” would be an “egregious violation” of North Korea’s international obligations.

He said it showed the need “to raise the cost to the leaders through the imposition of tough additional sanctions and of course by ensuring the thorough and rigorous enforcement of the existing sanctions.”

Russel said negotiations were “active” at the United Nations and that the United States and North Korea’s main ally China “share the view that there needs to be consequences to North Korea for its defiance and for its threatening behaviors.”

“Our diplomats are in deep discussion in New York about how to tighten sanctions, how to respond to violations,” he said.

Asked about China’s cautious response to U.S. calls for stronger and more effective sanctions on Pyongyang and Beijing’s stress on the need for dialogue, Russel said:

“Yet another violation by the DPRK of the U.N. Security Council resolution, coming on the heels of its nuclear test, would be an unmistakable slap in the face to those who argue that you just need to show patience and dialogue with the North Koreans, but not sanctions.”

White House spokesman Josh Earnest said China had “unique influence over the North Korean regime” and added: “we … certainly are pleased to be able to work cooperatively and effectively with the Chinese to counter this threat.”

Earlier on Tuesday, China’s envoy for the North Korean nuclear issue arrived in the capital Pyongyang, the North’s KCNA news agency reported.

North Korea last launched a long-range rocket in December 2012, sending an object it described as a communications satellite into orbit.

Western and Asian experts have said that launch was part of an effort to build an intercontinental ballistic missile.

North Korea has shown off two versions of a ballistic missile resembling a type that could reach the U.S. West Coast, but there is no evidence the missiles have been tested.

Pyongyang is also seen to be working to miniaturize a nuclear warhead to mount on a missile, but many experts say it is some time away from perfecting such technology.

North Korea said it successfully tested a hydrogen bomb last month but this was met with skepticism by U.S. and South Korean officials and nuclear experts. They said the blast was too small for it to have been a full-fledged hydrogen bomb.

Researchers find possible ninth planet beyond Neptune

CAPE CANAVERAL, Fla. (Reuters) – The solar system may host a ninth planet that is about 10 times bigger than Earth and orbiting far beyond Neptune, according to research published on Wednesday.

Computer simulations show that the mystery planet, if it exists, would orbit about 20 times farther away from the sun than Earth, said astronomers with the California Institute of Technology in Pasadena.

So far, the planet has not been observed directly.

“It’s a pretty substantial chunk of our solar system that’s still out there to be found, which is pretty exciting,” said astronomer Mike Brown, whose discovery was published in this week’s Astronomical Journal.

Brown and astronomer Konstantin Batygin, also at Caltech, initially were skeptical that such a large planet would have eluded detection.

But they modeled the hypothetical planet’s gravitational effects on several known bodies in the region and found a near-perfect match.

The computer model also predicted the location of other objects beyond Neptune, in a region known as the Kuiper Belt, and those were found in archived surveys as well.

At that point, “my jaw sort of hit the floor,” Brown said in a statement.

Brown’s earlier research helped to demote Pluto in 2006 as the solar system’s ninth planet after other small, icy bodies were found beyond Neptune.

“All those people who are mad that Pluto is no longer a planet can be thrilled to know that there is a real planet out there still to be found,” Brown said.

China to land probe on dark side of moon in 2018, Xinhua reports

SHANGHAI (Reuters) – China plans to land the first probe ever on the dark side of the moon in 2018, marking another milestone in its ambitious space program, the official Xinhua news agency reported.

China has launched a new round of work focused on lunar exploration, coming about two years after it made the first “soft landing” on the moon since 1976 with the Chang’e-3 craft and its Jade Rabbit rover.

Previous spacecraft have seen the far side of the moon, that is never visible from earth, but none has landed on it.

A new probe, the Chang’e-4, is similar to the Chang’e-3 but can carry a bigger payload, Xinhua quoted Liu Jizhong, head of the science, technology and defense industry administration’s lunar exploration center, as saying late on Thursday.

The craft will study geological conditions on the far side of the moon, Liu said.

Advancing China’s space program has been a priority of leaders, with President Xi Jinping calling for China to establish itself as a space power.

China insists that its space program is for peaceful purposes.

However, the U.S. Defense Department has highlighted China’s increasing space capabilities, saying it was pursuing activities aimed at preventing its adversaries from using space-based assets during a crisis.

In March, the Chinese government said it would open up its lunar exploration program to companies rather than simply relying on the state-owned sector as before, hoping to boost technological breakthroughs.

Xinhua said China sent “a letter of intent of cooperation” on its latest mission to foreign countries in early 2015. It was not clear if any had signed up.
