Seoul tracked Pyongyang rocket's successful space launch

Seoul, Feb 7 (IANS) South Korean’s military has seen a rocket launched by North Korea successfully entering into space, regarding it as a intercontinental ballistic missile similar to the Unha-3 rocket test-fired in late 2012.


South Korea’s Joint Chiefs of Staff reported on the launch to the parliamentary defence committee on Sunday, according to Rep. Yun Hu-deok of the main opposition Minju Party, a member of the committee, Xinhua reported.

The South Korean military estimated that North Korean rocket was a three-stage ICBM similar to the Unha-3 rocket, launched by Pyongyang in December 2012.

The rocket is believed to have a range of about 5,500-10,000 km. The first stage of the rocket fell in waters near South Korea’s western border island of Baengnyeong, with the second stage landing off the southwest of the southern resort island of Jeju.

Where the third stage landed has not been identified as it disappeared from radars of South Korea’s military.

To track the North Korean rocket after the launch, South Korea had deployed surveillance assets, including Aegis-equipped destroyer, ground-based Green Pine radar and Peace Eye airborne early warning and control aircraft.

No civilian damage in South Korea has been reported from aircrafts and shipping. The rocket did not fly over South Korea’s territory.

North Korea’s state media reported on Sunday that it had successfully launched a Kwangmyongsong-4 earth observation satellite into orbit just nine minutes and 46 seconds after the launch at 9.30 a.m. (local time).

Pyongyang has claimed the rocket launch is a space programme for peaceful purpose, but Seoul has denounced it as ballistic missile development. Rockets and ballistic missiles have lots of overlapping technologies.

The launch came a day after North Korea announced its revised plan to move up the launch window to February 7-14 from the previous February 8-25.

On January 6, Pyongyang said it had tested what it claimed was its first hydrogen bomb in violation of UN Security Council resolutions.

North Korea is banned under UN Security Council resolutions from testing a rocket by use of ballistic missile technology and staging a nuclear test. Pyongyang detonated atomic devices in 2006, 2009 and 2013.

South Korea’s presidential office criticised the launch, saying that it came in defiance of repeated warnings from the international community. Seoul called for tougher new sanctions against Pyongyang at the UN Security Council.

President Park Geun-hye convened an emergency meeting of the national security council, and Seoul’s foreign ministry requested an emergency meeting of the UN Security Council to discuss counter-measures.

South Korean Defence Minister Han Min-koo held a meeting with General Curtis Scaparrotti, commander of the US Forces in Korea (USFK), saying Pyongyang’s missile launch was a direct challenge to the international community as it came amid ongoing discussions at the UN Security Council about new sanctions against Pyongyang’s fourth nuclear test.

Han stressed the need for additional pressures on North Korea to make it recognise a fact that the country cannot survive unless it gives up nuclear weapons. He called for close cooperation between Seoul and Washington in response to a series of recent North Korean provocations.

Orellas de entroido

Hoxe, martes de entroido, non pode haber sobremesa sen unhas boas orellas.

E que ingredientes necesitamos para este doce tan típico noso?

  • 2 ovos grandes*
  • 1 ou 2 medidas de anís (para gustos)
  • 1 medida de aceite de xirasol
  • 200 gramos de fariña de trigo
  • azucre
  • un chisco de sal

(*) Usaremos a casca dun dos ovos para as medidas de anís e aceite, polo que ao escachar o ovo en lugar de facelo pola metade farémolo por un dos extremos.

Para a elaboración das orellas seguiremos os seguintes pasos:

1. Botamos os ovos nun bol

2. Engadimos o anís e o aceite

3. Engadimos unha grena de sal e unha cullerada sopeira de azucre

4. Batemos cun batedor manual

5. Engadimos a fariña pouco a pouco e imos mesturando

6. Mesturamos todo ata obter unha masa homoxénea. Engadimos un chisco de auga se vemos que a masa está demasiado sólida para traballar con ela

7. Amasamos ben durante uns dez minutos e deixámola repousar

8. Tras media hora de repouso, comezamos a formar pequenas bólas coa masa

9. Estiramos cada bóla coa axuda dun rodilo, rematando de dar forma coas máns, pero deixando  formas irregulares (as orellas non son circulares)

10. Fritimos en aceite ben quente, dándolles  forma de orella coa axuda dun ou  dous garfos (presionamos no medio xusto depois de introducir no aceite)

11. Colocamos sobre un papel de cociña que absorva o aceite sobrante

12. Espolvoreamos azucre por riba antes de que arrefríen

Poden sobrar para o dia seguinte, saben igual ou incluso mellor.

Agora xa non tedes excusa para non porvos máns á obra ;)

Controversial Rocket Launch: North Korea successfully places Satellite into Orbit

With a total launch mass of 90 metric tons, the Unha-3 rocket is capable of lifting 100 Kilograms into Sun Synchronous Orbit. The ascending rocket was tracked independently by Japan, South Korea, China and the United States. South Korean radars picked up the vehicle at 0:31:02 UTC and continued tracking the rocket and any debris it shed along the way until it was about 390 Kilometers in altitude and 790 Kilometers downrange.

Q&A: Does launch take N Korea closer to nuclear weapon?

North Korea launched a rocket carrying a satellite into space on Sunday - yet, it is not Pyongyang's extraterrestrial ambitions that have countries around the world worried. Instead, central to international concerns is whether North Korea’s rocket technology could potentially be used to also deliver a nuclear weapon. Al Jazeera technology editor Tarek Bazley spoke with aerospace engineer John Schilling to discuss the launch and whether the rocket could be turned into a ballistic missile. Al Jazeera: What do we know about Sunday’s launch of the Unha-3 rocket? John Schilling: It appeared to be very similar to the rocket they successfully launched in 2012 so apparently they are not trying to launch a new larger rocket like we had suspected.


READ MORE: UN Security Council condemns N Korea rocket launch
The rocket is certainly capable of launching satellites, because it has done so, but it is also capable of launching a warhead, if that is what they are interested in. Some of the design features suggest that it was optimised for satellite launch rather than missile work. But obviously anything that is capable of doing both missions is a concern to us Al Jazeera: Could this rocket be turned into an ballistic missile easily and quickly? Schilling: So far North Korea has launched satellites that go up into space and will eventually come down, but in an uncontrolled fashion and probably break up. To come down from the atmosphere from outer space at 28,000kmph and not disintegrate is technically challenging. They would need a re-entry vehicle with extensive heat-shielding given the speed. They would also have to worry about the stability of it. There are text books that will tell you how to do it and if the North Koreans are comfortable with book learning and with robust safety margins they could probably build something fairly quickly. Al Jazeera: How optimal is the Unha-3 as a ballistic missile? Schilling: It’s very large and cumbersome. We’ve seen this rocket in preparation for days and even if they streamline that process to hours ,you wouldn’t want to use that in a wartime. It’s dependent on a fixed launch site in a country as small as North Korea - and that is another risk for them. We’ve seen them parading and we think they are trying to develop a smaller mobile missile, the KN-08.
Analysis: Breaking down North Korea’s H-bomb test claim
It’s less than half the size of the Unha-3 and would carry a small nuclear warhead to the US West Coast but it could not reach Washington DC or other East Coast targets. This would be more useful for them but with no testing so far and a new design, we are thinking that’s not going to be operational until after 2020. Al Jazeera: Does the successful launch of the Unha-3 make North Korea more or less of a threat? Schilling: If North Korea were truly desperate they could probably build some sort of missile this year, but it would be very cumbersome, inaccurate and we’d see it on the pad before it was launched. Just the fact they launched anything so soon after a nuclear test is seen provocative and probably a violation of UN resolutions but the technical capability doesn’t seem to be a great advance on what they demonstrated in 2012. [The rocket technology] is obviously more reliable because they have two successful launches under their belt and it seems to have been more accurate. The last time they missed their intended orbit by about 25km and this time they were off by 15km so they are getting better but in small steps.

Satellites, Warheads and Rockets: Is North Korea’s Space Program Really about Missile Development?

John Schilling

February 5, 2016

Editor’s Note: While it’s unclear what SLV model North Korea will use in its upcoming satellite launch, if they use the Unha-3 rocket again, John Schilling discusses what lessons North Korea could learn. This article was originally published on September 28, 2015. 
When the Soviet Union shocked the world and opened the Space Age on October 4, 1957, it was not a coincidence that its first satellite was launched into orbit on a modified R-7 intercontinental ballistic missile (ICBM). For many observers, that was the message of Sputnik-the rocket that did this, can deliver hydrogen bombs to your cities. Nor was the message sent only once. The first 96 Soviet satellite launches were conducted using modified ICBMs, before Russian engineers bothered to design a rocket specifically for space missions. China still hasn’t bothered to field a space launch vehicle (SLV) that isn’t also a ballistic missile. On the other side of the world, every ICBM design the United States has ever put into service has been adapted to launch satellites at some time or another.
So when North Korea launched its first satellite on December 12, 2012, many observers thought the message was clear: the rocket that did this, can deliver atomic bombs to your cities. And indeed it can. But is this really the purpose of the Unha-3? Is it an ICBM masquerading as an SLV, or an SLV that might someday be repurposed as a missile? There is precedent for both. Or, as Pyongyang claims, is the Unha-3 intended purely for peaceful space exploration?
There are sound technical reasons for using the same rocket in both applications. The fundamental requirement for an ICBM is to accelerate a hydrogen bomb sized payload to roughly 16,000 miles per hour, just above the atmosphere and aimed about 20 degrees above the horizon. To launch a satellite, you want to be a little bit higher, flying horizontally at 18,000 miles per hour. Until your satellites grow larger than your bombs, there is no reason to develop a second rocket, and no way for suspicious outsiders to know for sure what your real goals are.
But if the Unha-3 is intended for use as an ICBM, it’s not a very good one . The second- and third-stage engines don’t have enough thrust to efficiently deliver heavy warheads; a militarized Unha might deliver 800 kilograms of payload to Washington, DC. The North Koreans can probably make a nuclear warhead that small, but it would be a tight fit. With bigger upper-stage engines, which we know the North Koreans have, they could deliver substantially larger payloads. This would allow bigger and more powerful warheads, more decoys to counter US missile defenses, and a generally tougher and more robust system.
The Unha is also too heavy and cumbersome to be survivable in wartime. Too big for any mobile transporter, it can only be launched from fixed sites. Its highly corrosive liquid propellants require hours of pre-launch preparations. That’s a bad combination for North Korea; their fixed launch sites are going to be watched very closely, and particularly in a crisis, any indication that an ICBM is being prepared for launch could trigger a pre-emptive strike.
The same could be said of the old Soviet R-7. As an ICBM, it was pretty much a dud-the USSR never deployed more than 10, and retired them after less than a decade. As a space launch vehicle, its descendants are still in service today.
The North Koreans could press the Unha-3 into limited service as an ICBM, just as the USSR did with the R-7-a temporary measure, until something better is available. They can almost certainly build something better, and they appear to be trying. The KN-08 missile mock-ups, twice paraded through Pyongyang, are exactly the sort of thing a nation like North Korea would build if it wanted to use its eclectic mix of early 1960s rocket technologies to build an ICBM. It is small enough to be mobile and therefore survivable but with the performance (barely) to reach the enemy’s homeland. The Unha-3, by comparison, looks like it was designed to launch satellites rather than warheads.

Imágenes por satélite confirman actividad en base norcoreana de misiles

Seúl, 29 ene (EFE).- Imágenes por satélite de la base norcoreana de Sohae confirmaron hoy que hay movimiento en las instalaciones y que Pyongyang podría estar preparando el lanzamiento de un proyectil de largo alcance, tal y como han advertido Seúl, Tokio y Washington.
Las imágenes publicadas y analizadas hoy por la web especializada en Corea del Norte 38 north, muestran “actividades de baja intensidad” en esta estación de lanzamiento situada en la provincia de Pyongan del Norte, en el extremo noroccidental del país.
Esto indica que el régimen de Kim Jong-un estaría en las “fases tempranas de preparación para el lanzamiento de un vehículo espacial”, una acción que el año pasado Pyongyang aseguró que realizaría en un futuro próximo.
Los lanzamientos de satélites a bordo de cohetes son sancionados por la comunidad internacional, que los considera ensayos encubiertos de misiles balísticos intercontinentales.
Corea del Norte lanzó por última vez un cohete Unha-3, con el cual puso en órbita un satélite de su programa Kwangmyongsong (“Estrella brillante”), desde esta misma base en diciembre de 2012.
Los movimientos detectados y reportados en la víspera por Japón y Corea del Sur, y más tarde confirmados por Estados Unidos, se producen poco después de que el régimen Juché realizara el pasado 6 de enero su cuarta prueba nuclear subterránea, la primera supuestamente con una bomba de hidrógeno.
38 north, web ligada a la universidad estadounidense Johns Hopkins, indicó que, aunque es “poco probable” que el lanzamiento se produzca a lo largo de la próxima semana, “es importante subrayar que hay un alto grado de incertidumbre” en torno a lo que sucede en Sohae.
La principal razón de esto, apunta el portal especializado, es que Corea del Norte mantiene cubierta la torre de lanzamiento y otras instalaciones próximas desde mediados del año pasado, lo que impide ver si el proyectil está siendo acoplado dentro de la estructura.
Además, indica que los técnicos norcoreanos pueden aprovechar la noche o los momentos en que el cielo esté cubierto (cuando los satélites son incapaces de obtener imágenes) para trasladar las fases del proyectil con las plataformas móviles y armarlo dentro de la torre recubierta.
El informe concluye diciendo que si “Corea del Norte mantiene las prácticas” de anteriores lanzamientos, en los próximos días se vería un incremento de actividad en toda la base de Sohae. EFE

Watch: North Korea’s Latest Rocket Launch

North Korea has released TV footage of the launch of a rocket it says put a satellite into space. Pictures show the North Korean leader Kim Jong-Un talking to members of his staff at the control centre before the blast-off. Then, after the device leaves the gantry and heads into the atmosphere, he is seen grinning as his commanders take notes.

We will now broadcast the Chosun record video of the successful launch of the earth satellite Kwangmyongsong-4 under the leadership of our respected leader Kim Jong-Un.

Kim Jong-

A South Korean official said the rocket appeared to be more powerful than North Korea’s Unha-3 rocket, launched in December 2012, with an increased range of 12,000km (7,500 miles) which, they said, puts most of the US within reach. The source told AFP the three-stage rocket was confirmed to have put an object into orbit but experts had not yet verified whether the alleged satellite was functioning.

Using the latest in nuclear rubberband technology, North Korea launched a rocket containing a satellite into space last weekend. And, well…
The North Korean satellite launched this weekend is tumbling in orbit, rendering it useless, just like another one of the country’s satellites launched in December, 2012.
A U.S. official told ABC News that while the Unha 3 rocket was able to get its payload into orbit, it has been tumbling ever since.
The Joint Space Operations Center (JSPOC) at Vandenberg Air Force Base in California has been tracking the North Korean satellite as well as a rocket booster stage that has also gone into orbit. […]
According to Space Command “The object with NORAD catalog identification number 41332 is KMS-4, the payload (satellite). The object with NORAD catalog identification number 41333 is UNHA 3 R/B, the rocket body.”
And a third object with NORAD catalog identification 41334 is labeled “Valet who missed piece of lint on Dear Leader’s favorite smoking jacket.”

Initial Assessment of North Korea Space Launch

North Korea’s Space Launch: An Initial Assessment

John Schilling

38north.org

February 9, 2016

At first glance, North Korea’s launch of an Unha Space Launch Vehicle (SLV) on February 7, 2016, looks very much like a repeat of its successful launch a little over three years ago. In fact, a close examination reveals that the North appears to have used some stock footage of the 2012 launch in its announcement this time around. But there are also images of a rocket launching from the new gantry that North Korea completed only last year. Moreover, the US Joint Space Operations Center (JSpOC) has released the orbital elements of two new bodies in stable orbits, with the identifiers “KMS-4” for the Kwangmyongsong-4 satellite and “Unha 3 R/B” for the launch vehicle’s upper stage rocket body. In short, this is not a hoax.
Images of the rocket departing the launch pad indicate an overall length of about 30 meters, the same as the Unha-3 rocket from North Korea’s 2012 launch. To the extent that we can tell from low-resolution images, the shape and the engine exhaust plumes are also nearly identical. North Korea did politely tell the mariners and airmen of the world where to expect the expended rocket stages to fall, and these also match the 2012 launch. The satellite itself is in a very similar orbit to 2012. While many had expected North Korea to debut a new and larger rocket, and the new launch pad was clearly built for a larger rocket, that launch is still in the future. North Korea might call this new rocket an Unha-4, but it is almost certainly an Unha-3 with, at most, minor modifications.
Several early reports indicated that the launch had failed, some saying that the first stage was seen on radar to have exploded; others that the rocket disappeared from radar shortly after the payload shroud had separated. These are common times for failure, and yet the satellite is in orbit. Most likely the rocket disappeared from radar at about the time it was passing out of range, with perhaps a moment of confusion while radar tried to track the payload shroud rather than the rocket.
But it does seem likely that the first stage did explode-after safely separating from the rocket. That’s a change from the 2012 launch, where the first stage fell into the ocean relatively intact and was recovered by the South Korean Navy. This could have been a late malfunction or a reaction involving unburnt residual propellant, but it could also be that the North Koreans didn’t want their southern neighbors to get quite so good a look at their rocket this time. Self-destruct mechanisms are frequently added to stages for “range safety,” to make sure no wayward rocket can land on a populated area, and it would be little trouble to deliberately activate one as soon as the first stage has done its job. Whatever minor modifications the DPRK may have made to the first stage will likely remain obscure.
Assume for the moment that North Korea is sincere in its claim that it just want to launch satellites. They are calling this one the “Kwangmyongsong-4,” and saying it is an Earth observation satellite. This is plausible enough, though “Earth observation” covers everything from improving weather forecasts and crop yields to military reconnaissance and targeting. North Korea’s first satellite accomplished little, tumbling out of control shortly after launch. At this point, North Korea would probably consider it a win if its satellite could hold a stable attitude, communicate with the ground and send back a few pictures…Read on.
