China develops sea launches to boost space commerce
BEIJING, July 7 (Xinhua) -- China has a clear plan to provide sea launches for commercial payloads to be carried by Long March rockets, according to an aerospace official.
Tang Yagang, vice head of the aerospace division of the No.1 institute of the China Aerospace Science and Technology Corporation (CASTC), said that the technology is not difficult and a sea launch platform can be built based on modifying 10,000-tonne freighters.
China will use solid carrier rockets which rely less on launch facilities and feature mature technology, Tang said, adding that key technology for the carrier rockets will be tested at sea this year and the service is expected to be available for international users in 2018.
At that time, Long March launch vehicles will be able to send satellites weighing 500 kilograms to a 500-kilometer-high sun-synchronous orbit with an inclination of zero to ten degrees, Tang said.
Countries in the equator region have growing needs for launching near-equatorial and low-inclination satellites, said Fu Zhiheng, deputy general manager of China Great Wall Industry Corporation, affiliated to the CASTC.
"The closer to the equator we launch a satellite, the less carrying capacity it will lose, and the lower the cost will be," Fu said, adding that space powers are competing to develop near-equatorial sea launches.
First hinted by an equivalent South Korean concept, as launching from near the equator would both improve the payload capability and reduce tensions with neighbouring nations produced by the launcher's overflight and drop zones.
Since North Korea is surrounded by hostile nations in the East and South, and has a maritime access to the South Oceans. Feasible by developing a civilian satellite launcher, based on the solid propellant Pukguksong-class TEL MIRV ICBM.
Numerological Analysis by Master S☫heil from Sohae, DPRK.
The first lucky number is already assigned to the future lunar exploration rocket Unha-9, with a lift-off mass of ~200t, a lift-off thrust of ~4 x 80tf and a LEO payload capacity of ~2t @500km. The next known North Korean launcher is designated Unha-20, with a LEO payload capacity of ~20t.
Any manned launcher would need increased reliability thus, extra luck. The next lucky number after 9 and before 20 is 18 (1+8=9). This one should be assigned to the liquid fuel manned launcher as the Unha-18.
The next lucky number after 20 is 27 (2+7=9).
Therefore any manned solid fuel launcher could safely be named Unha-27 thus providing extra safety to all future crews!
Chinese KZ-41 manned solid fuel launcher
Kuaizhou is a series of solid fuel TEL space launchers.
Chinese manned solid-fuel launcher KZ-41 for commercial orbital flights, from Expace Technology Co.(Expace), a commercial-launch venture, created by China Aerospace Science and Industry Corp. (CASIC), to market the solid-fueled Kuaizhou rocket globally.
The disclosed diameter and payload of KZ-21 are 4.5 m and 20 tons.
Iran has managed to design,manufacture,and test its new and powerful solid-fuel based Space launch Vehicle called Ghaem.
Ghaem project is part of a series of launchers, planned by Iran for next 10 years to meet its needs in the field of space launch vehicles for its space program.Ghaem is a four-staged all solid fuel expandable launch vehicle capable of launching payloads to LEO, MEO and GEO orbits and employs a very sophisticated design to be able to handle all types of payloads to those orbits.
Ghaem is not a man-rated launcher but many of its design specifications will be employed for our future manned space missions.
This prestigious and extremely sophisticated program was initiated and lead by Shahid Hajj Hassan Tehrani Moghadam and his team years ago and unfortunately experienced a set-back during a failed test back in 2011 which took the lives of several Iranian scientist including General Moghadam but eventually resulted in success in 2014. All stages are now flight-ready hardware.
With Ghaem Iran is now among a very elite group of space fairing nations capable of launching payloads to GEO and beyond.
While achievements in the field of defense made by Iranian rocket scientist Shahid Hajj Hassan Tehrani Moghadam are well known, little has been revealed about his last project, a 4-stages solid fuel launcher. According to data published in the national media, the first stage has a diameter of 3.5 m with a height of 20 meters and is designed to deliver a payload of more than 100 kg to an 1,000 kilometers LEO.
Advanced composite solid fuel HTPB was used in all new Iranian solid rockets.

It will use thrust vector control (TVC) for the first time in Iran
North Korean Pukgukson-Class manned solid fuel launcher
An uprated 4.5 meters diameter and 40 meters long Pukgukson-Class launcher could be used to launch astronauts to LEO. In this regard, the Tonghae Space Center's Launch Complex 3 (construction currently on hold), seems specially suited for this size of solid propellant launcher, with a ~10 meters base circular aperture for the flame's exhaust pit, compared to the ~7.5 meters by 7.5 meters rectangular exhaust's pit of the Sohae's Launch Complex 1 designed to support the ~3 meters to ~3.5 meters diameter Unha-9 launcher.

The Teng Yun, which CASIC intends to deliver by 2030, uses a TRCC-engined hypersonic carrier aircraft to carry the second rocket-powered stage into near space. Both stages will be reusable; the hypersonic carrier airframe could also be used to hypersonic strike and reconnaissance roles. The DSTO Teng Yun would have a combined weight of 100-150 tons. The first stage is a Mach 6 hypersonic 'carrier' aircraft, with TRCC engines. Teng Yun's second stage is a reusable, 10-15-ton rocket-powered spaceplane capable of carrying either 2 tons of cargo or 5 passengers.
Seemingly a two stages to orbit vehicle, with a vertical-takeoff, similar to the Chinese Teng Yun (腾云).
The hypersonic carrier airframe could be powered by an improved version of the North Korean scramjet engine used to power its new class of Hwasong-14 ICBM warhead, and revealed on 4 July 2017, by Korean aerospace analysts.
North Korean scramjet engine
If North Korea had made a Hwasong-14 ICBM with triconic nuclear warhead, it would not claim the missile as a "new strategic weapon that the world does not have and can not imitate." As you can see, the idea is that the Hwasong-14 ICBM is a completely new missile with no equivalent in the world and that can not be imitated. Like the Russian Topol-M ICBM nosecone, the long, thick conical-shaped Hwasong-14 warhead nosecone is an indication that the nosecone contains a scramjet-powered warhead that alters course midflight.

Both are ethnic Korean Chinese. No wonder Korea get access to such space technologies...
Li Xiangrong (李相荣, 리상영: Lee Sang Young)
2007년 1월 3일 (수) 15:10
Born in Korea (庆尚北道, Gyeongsangbuk-do) on 19 September 1941, Li Xiangrong settled in China with his father in 1942. Member of the Chinese communist party. Li Xiangrong , a Korean-Chinese scientist, was awarded the Grand Prize of the Chinese Academy of Sciences and the highest Science Prize in China. He was awarded this prize for the first time as an ethnic Korean in the People's Congress of Beijing at the end of last year. Born in Wuchang, Heilongjiang province, he has contributed to China's aerospace business for more than 40 years after graduating from the Beijing Institute of Technology.
He created "10 miracles out of 10" by placinging 10 satellites in space in 10 space launches.
Sent to the Soviet Union to study (electronics engineering?). Returned to China in 1962, and sent to the 581 Institute, the first in China to design satellite. Built the first DFH-1 satellite in 1970. Built remote sensing satellites.
China will open its space station to scientists worldwide after the station is completed around 2022, according to Wei Chuanfeng, on Thursday at the 2017 Global Space Exploration Conference, which was held in Beijing.
UN members, especially developing countries, could conduct scientific and technological experiment on Chinese space station, Wei said.
The space station will enable astronauts to stay in space for up to six months.
China will also help astronauts and payloads specialists from developing countries to enter into space, Wei said.

Difference betwen the first stages of the North Korean Kwangmyongsong LV (Unha-4) and the Iranian Safir-2A
https://www.jajusibo...92630403694.png ▲ Four Moksong-1 engines placed close to the center of the rocket stage, each sharing a common turbopump exhaust pipe with a lateral vernier, thus a total of four turbopump exhaust pipes, but verniers engines diverting fuel flow from the Moksong-1 engines and lowering their thrusts.
https://www.jajusibo...92631532303.png ▲ Four Shahab-3 engines are placed at greater distance from the rocket stage's center, each feeded by its own turbopump and exhaust pipe. A fifth exhaust pipe for another turbopump solely dedicated to the 4 verniers near the center, thus allowing higher thrust from the Shahab-3 engines.
Around two years ago an exhibition was held in Sharif university. One of the visitors of that exhibition wrote a good report about that exhibition and posted the photos of it too:
The engine of first stage of Safir SLV has been engine of a ballistic missile that Iran has reverse engineered it and has built different generations of it.
But he says unlike the engine of first stage , engine of second stage has been built by a engineering (designing) work not a reverse engineering work.
He says " This engine is built in "Space Research Institute". Before Iranians, scientists of Korea had tried to build this engine 7 times but each time after just 3 seconds the engine is exploded. Iranian young scientists try to build this engine 5 times and the engine works (burning time of engine) 150, 320 and 350 seconds in the last three times and finally the engine of second stage reaches to operational stage."
He says in Simorgh, this engines of second stage will be replaced with more thrust engines
Although it is said engines of second stage of Safir is based vernier engines of Russian R-27 missile, but difference of thrust of that engine and engines of Safir is very much so that it is possible to say engines of second stage of Safir isn't reverse engineering version of vernier engine of R-27, Thrust of vernier engine of R-27 is around 15 tons but thrust of each engine of second stage of Safir is around 3.5 tons.
Iran, which also learned missile technology from North Korea, announced on March 5, 2014 that "the Iranian Defense Ministry has equipped its Qadr H and Qiam ballistic missiles with its newly developed Multiple Reentry Vehicle (MRV) payloads, a military hi-tech owned only by a handful of the world states." If North Korea, who taught it, had made a Hwasong-14 ICBM with triconic nuclear warhead, it would not claim the missile as a "new strategic weapon that the world does not have and can not imitate."
In the last period, some countries attempted to develop nuclear weapons, but finally yielded to the collective pressure of the powers in collusion with them. Those countries did so because of lack of courage and will.
According to Iranian news agency ILNA, Mohammad Homayoun Sadr, the deputy head of the Iran Space Agency (ISA), made the announcement citing the extremely steep cost of a human spaceflight programme that he estimated was somewhere between U.S.$15-20 billion over 15 years. This price-tag is onerous for a well-functioning large economy, never mind one that is laboring under international sanctions, endemic corruption, failing economic policies, and lack of reforms as is the case with Iran.
Recent example of Korean reverse engineering with the Soviet T-72 MBT
The Soviet Union did not export the T-72 MBT to North Korea until its demise in 1991. After the Gulf War of 1991, hundreds of T-72s and T-80s were left shattered in Iraq and the Kuwaiti desert. Among them, many were still usable tanks. Some of the North Koreans military personnels who arrived in Iraq and Kuwait under the pretext of helping in the post-war reconstruction effort, had a special mission to get rid of the full T-72 left in the desert. They found a suitable T-72 and transported it via sea secretly. Through this dramatic secret mission, a T-72 arrived at a North Korean armored tank factory. This reverse engineered T-72 third-generation tank, is called the Chunma-92 MBT (천마-92). Further upgrades with the introduction of CNC machines, robots, and computers tools have produced the Chunma-98 MBT. Finally, in the early 2000s, the last model of the third-generation Chunmaho Tank series, the Chunma-216 tank was developed. From the middle of the 2000s, the Chunma series tank have been completely abandoned, with the development of the totally new Songun-915 series tank (선군-915).
Sarir ultra-heavy satellite-carrier is another space project due to be launched by March 2015 - March 2016.
The "Sepehr" should be available by 2015 or 2016. It is about 40m high, has a diameter of 3m. The first stage is equipped with new liquid fuel engines. The engines are bigger as the engines of the Safir and Simorgh. Each engine has about 50 tons of thrust. Combustion chamber, turbopump etc are unique, says the source. Further details are not known. However, it is developping a total thrust of 300 tons.
Conclusion: It is hard to believe that Iran has already the know-how to develop a new engine with about 50 tons of thrust, to bundle it to a cluster, add appropriate control engines, and to integrate it already by 2015 or 2016 in a functioning new rocket. Even North Korea has not this know-how. That can only mean that the technical requirements for such a propulsion already exist .........
Up to now all of the engines used in these countries, are always originated from the Soviet era. The advertised power of the new engines for example, corresponds to the RD-218 engines of the first stage of the R-16 ICBM, developed in OKB-586 Yangel.
Comment: This has already been debunked in various threads on other foreign dedicated space forums decades ago:
The Russian rockets scrap dealers
http://images.moviep...-1020547621.jpg ▲ Meanwhile, a few hundred miles north from where Anousheh blasts off, a ragtag band of scrap-metal merchants set off in their trucks for the spot where the first stage of the rocket will fall back to earth, providing rich pickings from its valuable metals. These will eventually be sold to China, where they are likely to be converted into aluminium foil of the kind used to wrap sandwiches. The scrap dealers enthusiastically agree that nothing is quite like beshbarmak (Kazakh lamb stew) cooked in the open air - especially when the cooking pot is a retrieved rocket part. And several hundred miles further north again, where the next stage of the rocket falls into a more populous area, farmers use the junk to mend houses and make tools, oblivious to the potential chemical hazards.
A few more successful satellite liftoffs will enable the North Koreans to use its powerful Unha carrier rockets to launch low-cost satellite launch services available to any interested client in the developing and the Western world.
Space development is a very promising future industry. If North Korea succeeds in the development of its geostationary satellite, this means that it would be able to launch GEO communication satellite and it can build its own GPS system.
Equatorial Guinea, a major oil producer in Africa, signed last June a contract with North Korea for 3.3 trillion won ($ 3 billion) for building a network. North Korea's communications network is known to use special technology that renders hacking by the United States simply impossible. Because of this, Equatorial Guinea had not hesitation in signing the contract with North Korea, and plans to extend the system to Africa. Equatorial Guinea is said to have a great influence in the African Union.
If North Korea secures its own communication satellites and exports those satellites to third world countries, it will be able to earn huge foreign currency. Former people's Libyan Arab Jamahiriya leader, Moammer El Gaddafi is also known to have been removed from power by the United States because of his geolocation done through wiretapping. Therefore, demand for communication satellites made in North Korea is not expected to be small.
The scientists of Kim Il Sung University have succeeded in developing a quantum code communications technology, which makes it possible to open up a bright prospect for blocking various kinds of hacking and wiretapping from their sources by taking hold of its core technologies.
The quantum code communications device makes use of such main properties of the quantum world as uncertainty relation and superposition principle, the main principles of quantum physics, to detect wiretapping on the spot, makes new codes and thus disables the hacking to keys.
This cutting-edge code technology requires special knowledge of various sectors including the technologies of quantizing laser beams, splitting and synthesizing light, controlling signals of transceivers and creating and decoding keys, together with the knowledge about the main principles of quantum physics.
All the problems of this new device, ranging from the basic designing of quantum code transmitter and receiver and the designing and making of a control panel to the programs of creating and decoding quantum keys, have been solved by their indigenous efforts and technologies.
The scientists have designed and manufactured an optical circuit for realizing quantum code "BB84 Protocol", developed a technology of controlling polarization of a photon, realized the distribution of quantum keys and, based on them, established a perfect security communications system. The new device absolutely guarantees the safety of keys even in case of the advent of a quantum computer.
Its inaccuracy rate is only 3.5 %, which is lower than the international allowable error of 10 %. And it can code all communications concerning images, sound and documents.
The Korean-style development of the quantum code communications device in the limelight of the world has made a breakthrough in the work for turning the above-said technology to practical use on a high level.
A group of high-rise condominiums "Future scientist street" (Mirae Scientists street) built in the central part of Pyongyang. Mirae Scientists Street, which is located by the side of Taedong River, is built with flats for thousands of families and more than 150 public catering outlets. The condominium apartment room here is provided free of charge to scientists and their families, and furniture and other items are all free of charge, so that the family of scientists can enjoy living in that residence. Furthermore, parades are organized to welcome scientists such as those involved in the experimental launch of the Hwasong 12, on May 14, 2017. Scientists will always be given a high preferential treatment according to the state's directives.
Newly developed residential area for scientists in the past few years, include Changgeon Street, Future Scientist Street, Galaxy Scientist Street, Satellite Scientist Housing Area, Yeonpung Scientist Recreation Area and also Munsu Water Park, Majyeong Stream Ski Resort, Mirim Equestrian Complex.
Kim Jong Sik started his career as a civilian aeronautics technician. Veteran rocket scientist.
North Korea's aerospace genius
In various missile tests, its appearance has been confirmed.
It is said that the age of the North Korean scientist is in the mid-50s.
However, the date of birth and career are unknown.
Although he is quite a mysterious person, the intelligence agencies of the US and south Korea think that Kim Jong Sik is the central figure who has made possible the breakthrough in North Korea's rocket technology.
In North Korea many contests are held in fields like mathematics and physics, and Kim Jong Sik has won the best awards many times, as his genius was already unmatched at the age of 10.
Then he enrolled at the Pyongyang Science University, and immediately after graduation he entered the Second Institute of Natural Sciences (the current National Defense Academy) and engaged in the development of rocket engines.
Furthermore, he was awarded the title of "Hero of the Republic", the highest honor in North Korea, for recognition of his achievements in rocketry development.
His genius was pivotal in the shift from liquid fuel to solid fuel rocket engines, such as seen in the Pukguksong-2 GLBM.
Jiyo Suzu Hiroshi (住友清太郎: Sumitomo Kiyotarō; 徐錫洪: Jiyo Suzu Hiroshi / ソ・ソクホン: So Sokuhon, Xu Xi Hong; 서석홍: Seo Seok Hong/Suh Seok Hong?)
23 May 2017
The genius Kim Jong Sik is presented as the North Korean chief designer.
There was also report that Jiyo Suzu Hiroshi (徐錫洪, 서석홍), a Korean born in Japan, and researcher with a doctorate from the University of Tokyo that is regarded as the authority of rocket engine development, and was involved in North Korea's "Kim Jong Motor Joint Venture Company", a rocket engine related company. Sumitomo Kiyotarō (住友清太郎) is the Japanese name that Jiyo Suzu Hiroshi used.
Space engineering experts pointed out that he is also called the North Korean von Braun, Jiyo Suzu Hiroshi is said to have made achievements in North Korea comparable to von Braun's in the American missile development. Jiyo Suzu Hiroshi graduated from the University of Tokyo Engineering department. After that, he joined the University of Tokyo Institute of Industrial Technology and received a doctorate. He is an expert in the promotion organization and sometimes awarded the American Power Engineering Society Award. However, there is no doubt that he was deeply involved in the development of the ballistic missile in the DPRK starting with the improvement of the Soviet Scud. It was around 1976 that North Korea acquired two Scuds via Egypt and started improvement. Jiyo Suzu Hiroshi, born in 1970, is in his mid-40s. It seems that he was in a position to lead rocket development.
Jiyo Bandō (徐判道: Jiyo Bandō, Xu Pan Dao; 서판도: Seo Pan Do )
Jiyo Bandō is a Japanese scientist graduate from the University of Tokyo. Industry Production Research Institute of Tokyo University, Work Examination Engine Expert Vice president of North Korea's Kim Jong Motor Joint Venture Company (「金剛原動機」). Jiyo Bandō also turned out to be visiting repeatedly North Korea, such as staying for a long time before the Unha-2's launch in April 2009. But with Jiyo Suzu Hiroshi, the two are involved in the North Korean rocket development.
Korean Association of Science and Technology in Japan (在日本朝鮮人科学技術協会)
North Korea has started the development of calculators since the 1980s, with the help of the Korean Association of Science and Technology in Japan (Kwahyop, 在日本朝鮮人科学技術協会). Among the 1200 members, 300 have visited Pyongyang during vacation and provided their expertise in fields such as calculators, semiconductors, robotics, rocket engines, chemistry, biology and nuclear physics. The most modern Western technologies in high thrust rocket engines have thus been transfered.
Machinery needed in the production of solid fuel for rocket have also been provided in 1994.
Japanese advanced defense technology transfered to North Korea
Since the end of the 1950s, North Korea has acquired heavy chemical industry and electronic technology secretly from Japan, and Chongryon (Korean Association in Japan) has played a role as an intermediary.
In addition to technology, US-made weapons have also been brought.
At that time, the traction vehicles and other vehicles of the North Korean People's Army were almost all Japanese Nissan, Isuzu and Mitsubishi. North Korea had CASIO fx series calculators, NEC PC-9801, MBC-555 and MZ-800. At that time, the Soviet Union and China said they had to go to Pyongyang to get Japanese computers.
Until the early 1980s, the basic reason why North Korea's science and technology and economy surpassed China and South Korea was also found here, and North Korea was the source of technology that the Soviet Union has not been able to develop by itself.
In fact, last year [in 2016], North Korea showed that its ultra-precision striking capability does not use any Russian radar.
Why did Japan so secretly help North Korea long before South Korea did?
According to sources, the period was when North Korea played the role of Japan's gateway to the continent. At that time, Japan seemed desperate for an easy access to China and the USSR.
In addition, most of the post WWII Japanese leaders at that time had tasted Kim Il Sung's unmatched guerrilla warfare, who had made 1 million Japanese Kwantung troops tremble in Manchuria during the 1930s, and they had experienced with World War II in the 1940s, and the following Korean War in the 1950s. Therefore, they regarded General Kim Il Sung as an invincible adversary leader and accepted almost all of Kim Il Sung's requests, while publicly kepping the secret.
Japan may have worried that if North Korea was to be completely occupied by the US and if the US was to take control of all Northeast Asia, it would move its military bases from Japan to the Korean peninsula.
If you occupy North Korea, you might say that the US would then make Japan to become a tributary state of the US like Hawaii. Just as Hawaii was a tributary state of the US, the majority of the Aborigines disappeared, just as American Indians were completely destroyed by European immigrants.
The leaders of Japan may have considerd Kim Il Sung as a person able to defend Northeast Asia from such an American world domination strategy.
It seems that this mighty North Korean military science and technology has been combined with the advanced technology of Japan as well as the science and technology of Russia and Eastern Europe that have been learned through foreign students.
Agreement on the Rescue of Astronauts, the Return of Astronauts and the Return of Objects Launched into Outer Space
February 23. 2016 Juche 105
DPRK Accedes to Space-related International Agreements
Pyongyang, February 23 (KCNA) -- The DPRK acceded to the agreement on the rescue of astronauts, the return of astronauts and the return of objects launched into outer space and the convention on international liability for damage caused by space objects on February 22, Juche 105 (2016), according to the decision of its government.
The agreement concluded on April 22, 1968 stipulates the issue of handing over to the launch nation any astronaut, space objects and their parts as they fall or are discovered in the territorial land and waters of a signatory country and open sea.
The convention concluded on March 29, 1972 undertakes a launch nation to make responsible compensation when space objects caused human or property losses on the earth surface or caused damage to a plane in flight.
The DPRK's accession to the agreement and the convention will further promote the international trust in space scientific researches and activities and make positive contributions to strengthening cooperation with other countries.

19 December 1966.
States Parties to the Treaty shall regard astronauts as envoys of mankind in outer space and shall render to them all possible assistance in the event of accident, distress, or emergency landing on the territory of another State Party or on the high seas. When astronauts make such a landing, they shall be safely and promptly returned to the State of registry of their space vehicle.
In carrying on activities in outer space and on celestial bodies, the astronauts of one State Party shall render all possible assistance to the astronauts of other States Parties.
States Parties to the Treaty shall immediately inform the other States Parties to the Treaty or the Secretary-General of the United Nations of any phenomena they discover in outer space, including the moon and other celestial bodies, which could constitute a danger to the life or health of astronauts.
Kwangmyongsong (Korean for guiding light or Polar Star) refers to the late Kim Jong Il. The name was given by the members of the anti-Japanese guerrilla army when he was born at a secret camp on snow-covered Mt Paektu, expressing their desire that he would grow into a Korean "King David".
Jong Il Peak rises high on Mt. Paektu The blue waters of the Sobaek meanders; Here, 50 years ago, the Shining Star was born A master with pen and sword, loyal and dutiful. He commands respect and praise from all. And the cheers for him rock heaven and earth.
In April 1992, North Korea mulled two events for the festivities. The first one was a large scale military parade and the second one was a satellite launch. However, President Kim Il Sung said that the proposed launch of a satellite was untimely and had no significance. So the launch was postponed until August 1998.
The DPRK's space program began in the 1980's with the creation of the Korean Committee for Space Technology (KCST). In the 1990s, North Korean scientists developed an experimental satellite, Kwangmyongsong-1 or "Bright Star" or "Shining Star."
According to the DPRK's Kim Jong Il Biography 3, when the scientists developing KMS-1 were discouraged, the Chairman reminded them that the first Korean Chollima-brand tractor "had run backward on its trial drive." Encouraged, the scientists "drew fresh designs and compiled technical data within a year," something which would have taken "five years to be completed in ordinary times" and within two years had completed KMS-1's launch vehicle. ... The DPRK-produced biography of Kim Jong Il, The Great Man, in discussing the development of KMS-1 and 2, even admitted that the fact that the DPRK had launched a satellite at all "can be said to be a miraculous event."
Academician, Prof. and Dr. Kwon Tong Hwa, Kim Il Sung order winner, labour hero and deputy to the Supreme People's Assembly, who was involved in the launch said that the DPRK has long since developed the science and technology of artificial satellites and laid its solid industrial foundation, not boasting of it. He explained the background of the launch of the satellite: Under the wise guidance of General Secretary Kim Jong Il, the DPRK has developed a multi-stage rocket capable of carrying an artificial satellite already in the 1980s and made remarkable successes in researches into satellites as well. When he was alive, the President Kim Il Sung said that it was high time for the DPRK to launch an artificial satellite. All preparations for the launch had been completed in Korea already at the beginning of the 1990s. As instructed by Kim Jong Il, the first artificial satellite was launched to significantly adorn the first session of the 10th Supreme People's Assembly and the 50th anniversary of the founding of the DPRK. ... Candidate academician, Prof. and Dr. Han Hae Chol, Kim Haeng Gyong and other scientists, who were involved in the launch of the artificial satellite "Kwangmyongsong No. 1," referred to the purpose of the launch: First, it is to master the technology of putting a satellite correctly into orbit with a multi-stage carrier rocket. Second, it is to perfect the structural engineering design of a multi-stage carrier rocket and its control technology. Third, it is to study the circumstances of the space and verify if electronic devices correctly operate in the space. Fourth, it is to complete the observation system of the carrier rocket and satellite. For this purpose, necessary observation devices were installed at the carrier rocket and satellite. ... The scientists chose the sky above Tsugaru strait between Hokkaido and Honshu, Japan, as the trajectory of the recent artificial satellite launch. The carrier rocket was equipped with a device with which to lead the rocket to a safe area and explode it in case the flying rocket is deviated from the expected trajectory. ... A scientist Kim Haeng Gyong who had participated in the launch said the carrier rocket correctly flied along the theoretically expected trajectory and that all the apparatuses of the artificial satellite are working properly after it was put into orbit. ... The artificial satellite moving along its own orbit sends them survey data, including temperature, pressure and conditions of power source, they said. The sketch map of the test launch of the carrier rocket of the artificial satellite shows where the carrier rocket was separated stage by stage and where the separated parts of the rocket dropped. It shows that the first stage was separated from the rocket 95 seconds after the launch, in the air 35.9 kilometres high and 19.5 kilometres off the launching station, that the second stage separated itself from the rocket in 266 seconds, in the air 204 kilometres high and 450.5 kilometres off the launching station and that the artificial satellite was put into orbit in 293 seconds, at the speed of 8,980 metres per second, in the air 239.2 kilometres high and 587.9 kilometres off the launching station. It also shows that the first stage separated from the rocket fell 253 kilometres off the launching station, that is 40 degrees 51 minutes north latitude 132 degrees 40 minutes east longitude and that the second stage fell 1,646 kilometres off the launching station, that is 40 degrees 13 minutes north latitude 149 degrees 07 minutes east longitude.
The first artificial satellite of the DPRK launched at Musudan-ri, Hwadae county, North Hamgyong Province, on August 31 is now revolving round the earth. The multi-stage carrier rocket and satellite launched by Korean scientists and technicians were developed with local strength, wisdom and technology 100 percent. Today's edition of Rodong Sinmun carries an interview with scientists and technicians involved in the satellite launch and a sketch map of the carrier rocket launching test. The first and second rocket stages are made up of liquid rocket engines and the third stage an engine with highly efficient solid fuel. The control mechanism of the rocket is a product of advanced science and technology, including computers. The first stage was separated from the rocket 95 seconds after the launch and fell on the open waters of the East Sea of Korea 253 km off the launching station, that is 40 degrees 51 minutes north latitude 132 degrees 40 minutes east longitude. The second stage opened the capsule in 144 seconds, separated itself from the rocket in 266 seconds and fell on the open waters of the Pacific 1,646 km off from the launching station, that is 40 degrees 13 minutes north latitude 149 degrees 07 minutes east longitude. The third stage put the satellite into orbit 27 seconds after the separation of the second stage. The purpose and mission of the rocket were accomplished at the first launch.
According to a press release issued by the National Aerospace Development Administration on February 7, 2016, the orbit inclination angle of Kwangmyongsong-1 and Kwangmyongsong-2 were 40.2 degrees and 40.6 degrees, respectively.
19th year ago, on Juche 87 (1998), August 31, at 12:07, the day of the 50th anniversary of the founding of the Democratic People's Republic of Korea, the nation launched its first ever man-made test satellite. It was launched heading a 86 ° direction and entered a Low Earth orbit exactly after 4 minutes 53 seconds.
As a matter of course, the second-term Clinton administration initially condemned the August 31, 1998, satellite launch as a ballistic missile test in disguise. However, it went out of its way two weeks later to retract its initial assessment, calling it "a satellite". ... On September 4, an anonymous US intelligence officer told Reuters, "We have seen that report and we are still evaluating the data connected with the launch and we cannot at this point rule out that an object was placed in orbit." The Reuters news story was headlined, "US Can't Rule Out N Korea Launched Satellite. ... Ten days later, September 14, the State Department courageously backed away from its initial assessments and acknowledged that the object launched by North Korea in the western Pacific two weeks earlier was a satellite and not a missile. State Department spokesman James P Rubin told AP, "The object launched by North Korea in the western Pacific two weeks ago was a satellite and not a missile."
The separation of the first and second stages was successful at that time. The third-stage engine seemed to have exploded just about two seconds before the satellites entered the orbit, and the debris, along with launcher, was scattered about 4000 kilometers from the launch site. ... According to a detailed analysis of the rocket launch from the Japanese "Defense White Paper" in 1999, a small object from the third stage was able to fly for a while but could not enter orbit.
Numerological Analysis by Master S☫heil from Sohae, DPRK.
Launch date (Pyongyang): 5 JUL (20)06
5+7=12 thus exceeding the lucky number of 9!
Strongly advised to Not Proceed with any space launch attempt on that Unlucky date!
11 July 2006
Just 42 seconds after its 5 July launch, the rocket plunged into the Sea of Japan, according to US, South Korean and Japanese intelligence. ... "It's very hard to get this far," The failure appeared to take place at the moment rocket designers call 'maximum q', when a rocket feels the greatest aerodynamic forces. ... the first stage had probably not finished firing by the time of the crash something fell from the rocket immediately after take-off. ... He thinks that part of the final, third stage may have pulled loose when under maximum strain, and struck the body of the rocket.
That 'something' may have been a shroud covering a small satellite that the North Koreans intended to put into orbit, Vick says. Such a problem would be relatively easy to fix, he notes. "If the shroud is the problem, we could see another flight within a year or less."
But other types of failure are just as likely, says McDowell. For example, the steering mechanisms might not have been strong enough to guide the rocket at maximum q, or a software or guidance glitch might have caused the crash. If the latter were true, he says: "They could fly it again in a few months."
McDowell adds that regardless of the specifics of the failure, the 42-second flight shows that the North Koreans are indeed skilled at rocketry. Most launch failures occur within the first few seconds after lift-off, he says. During the early days of the US programme, says McDowell, a 40-second flight would have been described as a 'partial success'.

The Taepodong-2 landed about 200 miles west of Japan in the Sea of Japan, a U.S. military source said. ''' "It's very difficult technology. They very clearly have not mastered it," Jim Walsh, a national security analyst at the Massachusetts Institute of Technology, said. "Most estimates are they will not master it for another 10 years."
The launch was a scientific research experiment partly intended to serve as a firework display to celebrate the re-election of Kim Jong Il as the all-powerful National Defense Commission, partly to demonstrate that North Korea has joined the two elite clubs of nuclear powers and space powers, and partly to signal it will join a third elite club of economic tigers by 2012.
Preparations for Launch of Experimental Communications Satellite in Full Gear
The preparations for launching experimental communications satellite Kwangmyongsong-2 by means of delivery rocket Unha-2 are now making brisk headway at Tonghae Satellite Launching Ground in Hwadae County, North Hamgyong Province.

KCNA on DPRK's Successful Launch of Satellite Kwangmyongsong-2
Pyongyang, April 5 (KCNA) -- Scientists and technicians of the DPRK have succeeded in putting satellite Kwangmyongsong-2, an experimental communications satellite, into orbit by means of carrier rocket Unha-2 under the state long-term plan for the development of outer space.
Unha-2, which was launched at the Tonghae Satellite Launching Ground in Hwadae County, North Hamgyong Province at 11:20 on April 5, Juche 98 (2009), accurately put Kwangmyongsong-2 into its orbit at 11:29:02, nine minutes and two seconds after its launch.
The satellite is going round the earth along its elliptic orbit at the angle of inclination of 40.6 degrees at 490 km perigee and 1,426 km apogee. Its cycle is 104 minutes and 12 seconds.
Mounted on the satellite are necessary measuring devices and communications apparatuses.
The satellite is going round on its routine orbit.
It is sending to the earth the melodies of the immortal revolutionary paeans "Song of General Kim Il Sung" and "Song of General Kim Jong Il" and measured information at 470 MHz. By the use of the satellite the relay communications is now underway by UHF frequency band.
The satellite is of decisive significance in promoting the scientific researches into the peaceful use of outer space and solving scientific and technological problems for the launch of practical satellites in the future.
On April 5, 2009, at 11:20 am, a test telecommunication satellite Kwangmyongsong-2 was launched on a Unha-2 rocket. The satellite was injected into orbit after 9 minutes and 2 seconds and was able to send measurement data transmission and relay communication.
Note, this is an edited version, with some scenes removed from the original footage! Animation sequences of the launch from the North Korean drama movie The Country I Saw - Part 3 (2009) (start at t=1h16m09s) ( 내가 본 나라 3 (2009): start at t=1h19m16s, 我所见的国家 3) by Ko Hak Rim and Pak Jong Ju.
Pyongyang, May 7. 2009 Juche 98 (KCNA) -- A spokesman for the Korean Committee of Space Technology issued a statement on Thursday, one month after satellite Kwangmyongsong-2 started its normal operation after being put into orbit.
The observation by the satellite and a control test were normally conducted despite the unidentified strong jamming done in the above-said communications frequency band, in particular.
The International Telecommunication Union (ITU), the international agency in charge of radio frequency allocation for satellites, dismissed North Korea's claim to have put a communications satellite into orbit
Security Council Condemnation of North Korean "UFO"
Notably, the Council nowhere spelled out what North Korea might have launched, for the simple reason that its members could not agree: some thought missile, some thought satellite. Unable to agree on a noun, it therefore compromised with the verb "launch." The Council's strong and peremptory diplomatic language - "condemns," "demands," etc was therefore oddly out of kilter with its inability to decide what it was condemning. Essentially it was saying North Korea was not to launch any more unidentified flying objects, or "UFOs." "Whatever it was you launched," said the Security Council in effect, "you should not have and you must not do it again."
Kim Jong Un Inspects KPA Air and Anti-Air Force Unit 447
Pyongyang, May 14 (KCNA) -- Supreme Commander of the Korean People's Army Kim Jong Un, first secretary of the Workers' Party of Korea and first chairman of the National Defence Commission of the DPRK, inspected KPA Air and Anti-Air Force Unit 447 honored with the title of O Jung Hup-led 7th Regiment.
"Whenever I visit the airfield where airmen are active, I feel as if I were entering the yard of my old home," he added.
He highly praised the unit, saying the unit which produced 14 human bomb-like fighters is the unit which gave origin to the heroic, self-sacrificing and self-blasting spirit of the brave red hawks of Songun Korea.
he praised the unit for maintaining with good care the plane and always keeping it fully ready to make sortie and thereby letting it take the lead in flight drills at all times.
It is necessary to intensify training in order to shed less blood in battle, he noted, calling upon airmen to intensify the training so that they may satisfactorily perform combat flight mission including take- off and landing under the worst conditions. He said that airmen should make it part of their life and habit to undergo training with the help of modern piloting training equipment while flying aircraft a lot and thus make the unit intensify the training
Supreme Commander of the Korean People's Army Kim Jong Un, first secretary of the Workers' Party of Korea and first chairman of the DPRK National Defence Commission, Monday visited Unit 447 of the KPA Air and Anti-Air Force honored with the title of O Jung Hup-led 7th Regiment and planted trees with fighter pilots of the unit.
On the same day, he went round a monument to the merits of 14 stalwart fighters, who displayed the suicidal-attack spirit, at the unit. This monument was built, under the deep care of the Supreme Commander, to convey the heroic feats performed by the 14 fighter pilots in the operation to ensure the successful launch of satellite Kwangmyongsong-2.
Citing North Korea's earlier news reports, South Korean officials said that at least one of the 14 airmen was killed due to a jet crash on the eve of the rocket launch.
"It's presumed that a pilot was killed as a MiG-23 fighter jet crashed into the waters near the launch site in Tonghae while conducting a patrol flight against a possible attempt to intercept the rocket," a unification ministry official told reporters on background.
The pilot received a posthumous medal and 13 others were awarded watches with the name of Kim Jong Il, he added.
... plans of the Kim Jong Il administration for economic prosperity by 2012 - the centenary of the birth of founding father Kim Il Sung - in a bid to complete its membership of the three elite clubs of nuclear, space and economic powers.
Wernher von Braun was born in Wirsitz, today in Poland, only 24 days before the DPRK's founder and leader, Kim Il Sung, on 23 March 1912.
Affiliated with the German Nazi party, and himself promoted SS officer, von Braun served his national socialist masters and worked for the German war effort designing the Aggregat ballistic missiles.
Soon after Germany's unconditional surrender of May 1945, von Braun would lead the surrender of his entire team only to serve his new American captors.
The Germans' collaboration would be pivotal for the new hegemonic U.S. war machine, by developing the world first satellite carriers in less than a year after von Braun's arrival on 20 September 1945 in Fort Strong, Boston.
The April 2012 launch of Kwangmyongsong-3 is meant to celebrate the 100th birth anniversary of leader Kim Il Sung, greatest and indomitable anti fascist guerilla commander, while totally keeping in the shadow his predecessor's, eternal lackey of the militarists and stooge of the imperialist puppet masters.

WASHINGTON--A senior North Korean government official informed the United States before the death of Kim Jong Il was announced in December of its plan to launch a satellite, according to a former senior U.S. government official.
In an article for a U.S. research institute, Evans Revere, who served as acting assistant secretary of state under the administration of President George W. Bush, wrote that the decision to carry out the launch is highly likely to have been made by the late North Korean leader.
Revere therefore hinted that the launch would be unavoidable, as "his son and successor was in no position to reverse that decision."
Revere met with the North Korean official on Dec. 15 and was told about the planned launch of what some people believed to be a missile.
The meeting is believed to have taken place in New York.
Kim Jong Un, has ordered the Korean Committee for Space Technology to invite a bevy of experienced foreign experts on space science and technology and journalists to observe the satellite liftoff at the country's ultra-modern satellite launch center.
There are two reasons for Kim Jong Un's decision: One is to provide the promised maximum transparency for the launch and the other is to add to the festive nature of the celebratory event. Obviously, there is nothing to conceal about the peaceful satellite launch,
the payload mounted on the Unha (Milky Way) rocket is a polar-orbiting observation satellite. It is designed to transmit important prospecting data on the underground resources of the Korean Peninsula, as well as weather and mapping data.
A: Kwangmyongsong-3 has video camera mounted on it and will send observation data including pictures to the General Satellite Control and Command Centre. It weighs 100kg and will circle along the solar synchronous orbit at 500km high altitude. Its life is two years.
The DPRK is to launch a working satellite, Kwangmyongsong-3, manufactured by itself with indigenous technology to mark the 100th birth anniversary of President Kim Il Sung.
A spokesman for the Korean Committee for Space Technology said this in a statement Friday.
After successfully launching two experimental satellites, DPRK scientists and technicians have steadily conducted scientific researches to develop and utilize working satellites indispensable for the country's economic development in line with the government's policy for space development and peaceful use.
Through the researches they have made a drastic progress in the field of space science and technology and laid solid material and technological foundations for working satellite launches and operation.
Kwangmyongsong-3, a polar-orbiting earth observation satellite, will be blasted off southward from the Sohae Satellite Launching Station in Cholsan County, North Phyongan Province between April 12 and 16, lifted by carrier rocket Unha-3.
A safe flight orbit has been chosen so that carrier rocket debris to be generated during the flight would not have any impact on neighboring countries.
The DPRK will strictly abide by relevant international regulations and usage concerning the launch of scientific and technological satellites for peaceful purposes and ensure maximum transparency, thereby contributing to promoting international trust and cooperation in the field of space scientific researches and satellite launches.
North Korea reportedly informed on March 16, the ITU headquarters in Geneva of the satellite launch stating, "We will launch the earth observation satellite Kwangmyongsong-3 (Shining Star-3), some time between 7AM and 12AM within the 12th-16th time period of next month."
The satellite will broadcast remote data in the UHF band and video in the X-band, the ITU quoted the DPRK" notification as saying.
The UHF band runs from around 300MHz to 3GHz and has several chunks of frequency reserved for satellite use. It's commonly used by satellites to send data back to earth.
The X-band runs from around 7GHz to 12GHz and is most often used via satellite for military and government communications.
The Unha-3 is the backup rocket of the 2009 Unha-2 launch and the previous red "Choson" paint was covered by the blue "Unha-3" letters.
North Korea has spent the last three years developing the Earth Observation satellite Kwangmyongsong-3 with 100 meters ground resolution. The Korean Space and Space Technology Committee, which has been out of the question, is expected to make technological progress to reduce the resolution from 100 m to 30 m in the next few years.
Fridays have been considered an unlucky day since the medieval times. In Britain, Friday was the conventional day for public hangings, and there were supposedly 13 steps leading up to the noose! Adam and Eve ate the forbidden fruit on a Friday and later died on a Friday. Christians consider Friday as the day on which Christ was crucified by the Romans.
Tarot Card number 13 is the Death Card, depicting the Grim Reaper Hotels rarely have a room number 13 There are 13 steps leading to the gallows. 13 knots in a hangman's noose. 13 feet which the guillotine blade falls.
The decision to proceed with the launch on Friday 13 was a big tactical mistake, provided Kim Jong Un is an overseas student returnee from the West and could't ignore the sinister meaning of the unlucky number 13!
In Sohae SLC, Unha LV are launched with low humidity and low wind speed to avoid the danger of malfunction due to the generation of static electricity in various electronic devices installed in the propulsion module.
All satellites are launched when the sky is sunny. Therefore satellites can receive the maximum amount of solar energy. If the satellite that entered the earth's orbit is flying in the shadow of the earth and can not receive solar energy, it will consume too much electricity of its onboard battery and shorten its service life.
Pyongyang, April 13 (KCNA) -- The DPRK launched its first application satellite Kwangmyongsong-3 at the Sohae Satellite Launching Station in Cholsan County, North Phyongan Province at 07:38:55 a.m. on Friday.
The earth observation satellite failed to enter its preset orbit.
Scientists, technicians and experts are now looking into the cause of the failure.
Kim Min Seok of the South Korean Ministry of National Defense said to reporters, that the Unha-3, which was launched at 7:38:55 am, separated its first stage at 70.5 km after about 135 seconds (2 minutes 15 seconds) from the launch time. After about 241 seconds (4 minutes and 1 second), it rose to 151.4 km altitude. After about 527 seconds (8 minutes 47 seconds) from the launching time, the emergency self-destruct device was activated and it has fallen. The launching time of the first stage propulsion unit of the Unha-2, which North Korea launched on April 5, 2009, was 120 seconds, and the first stage propulsion combustion time of the Unha-3 was about 135 seconds. Comparing the burning time of the first stage rockets, the Unha-3 was longer than the Unha-2 by about 15 seconds. Note that the Unha-3 successfully separated the first stage about 135 seconds from the launch time.
Pyongyang, December 1 (KCNA) -- A spokesman for the Korean Committee for Space Technology issued the following statement Saturday:
The DPRK plans to launch another working satellite, second version of Kwangmyongsong-3, manufactured by its own efforts and with its own technology
Scientists and technicians of the DPRK analyzed the mistakes that were made during the previous April launch and deepened the work of improving the reliability and precision of the satellite and carrier rocket, thereby rounding off the preparations for launch.
The polar-orbiting earth observation satellite will blast off southward from the Sohae Space Center in Cholsan County, North Phyongan Province by carrier rocket Unha-3 in the period between December 10 and 22.
A safe flight path has been chosen so that parts of the carrier rocket that might fall during the launch process would not affect neighboring countries.

And the red line is the launch azimuth at this time. If you want to get in the ideal trajectory, you have compensate this difference. When the launch azimuth angle is set to 97.4 degrees, the flight path will enter the high population density coastal areas in China. So dropping things here will not be fancy. If the currently issued NOTAM is correct, then there is only one method. It is to bend the flight path to the west side after the third stage ignition. This is a flight path known as the dog leg, which is also used when launching from Japan to the sun synchronous orbit. However, in order to do this dog leg, we have to make very accurate guidance and we need considerable leeway capacity. At the moment we do not know whether they can make a detailed guidance so far with the first launch, and whether the launcher has that capacity or not.
Pyongyang, December 10 (KCNA) -- The spokesman for the Korean Committee of Space Technology Monday released the following statement:
As already reported, scientists and technicians of the DPRK are pushing forward the preparations for the launch of the second version of Kwangmyongsong-3, a scientific and technological satellite, at a final phase.
They, however, found technical deficiency in the first-stage control engine module of the rocket carrying the satellite and decided to extend the satellite launch period up to Dec. 29.
Supreme commander of the Korean People's Army, gave a final written order regarding the launch of the second version of Kwangmyongsong-3 to the Korean Committee of Space Technology at 8 a.m. on December 12, 2012.
He visited the General Satellite Control and Command Center at 9 a.m., one hour before the launch.
Kim Jong Un learned about the preparations for the launch and issued an order on the launch and keenly observed the whole processes of the launch.
Kim Jong Un expressed great satisfaction over the successful launch of the satellite.
First March 27, 2013 ground pictures of the Kwangmyongsong-3#2 satellite confirmes successful unfolding of the two solar side-panels, and their correct orientation away from the Earth surface, toward the Sun, thus revealing the underneath yellowish-gold color multi-layer insulation.
The wireless communication equipment aboard Kwangmyongsong-3 sends out the wireless signal only for a short time window when in range with ground stations over North Korea. A third party who does not know the frequency of the radio signal that the satellite is transmitting will not be able to intercept the radio signal originating from that satellite at any particular time.
Kwangmyongsong-3 and Kwangmyongsong-4 are largely used as reconnaissance satellites.
The Earth observing satellite of North Korea passes through the East Sea four times a day, passing through the East Sea once in about 3 hours, because it alternates between Kwangmyongsong-3 and Kwangmyongsong-4.
Surveilling the Korea Operational Zone and the Japanese Oki Islands (隱岐岛), it monitors the appearance of the US aircraft carrier group.

North Korea close to completing upgrades to Sohae launch site
24 June 2015
Ongoing modifications to the launch pad at North Korea's Sohae satellite launch centre suggest it will be the location for upcoming satellite launches.
Paek Chang Ho, vice director of Scientific Research and Development at National Aeronautics Development Agency (NADA), said in an Associated Press interview in late May that a new "earth observation satellite" was under development. He did not say which space launch vehicle (SLV) would be used, when the launch would occur, or from where it would be launched.
Nonetheless, North Korea's modus operandi of linking major technological developments to important dates for the nation has led to speculation that it could be launched in October to coincide with the 70th anniversary of the Korean Workers' Party.
Sohae (also known as Tongchang-ri) is on North Korea's West Sea/Yellow Sea coast and is one of two space launch facilities in the country; the other is Tonghae (also known as Musudan-ri), which is on the East Sea/Sea of Japan coast.
Satellite imagery of the Tonghae facility taken on 6 June 2015 shows no significant activity at the site. Construction of a large new launch pad, assembly building, and the supporting roads has stopped and the Unha-2 pad that was last used in 2009 appears to be mothballed.
The lack of activity at Tonghae - and a number of other factors - reinforces assertions that Sohae has become the main hub for North Korea's space and long-range missile programme. Analysts have suggested that Pyongyang has prioritised the Sohae site to minimise the diplomatic fallout of rocket debris landing in Japanese territory, which was possible with launches from Tonghae.
There have been two launches from Sohae since its public debut in 2012, although neither has been fully successful. An Unha-3 launch in April 2012 suffered a catastrophic failure in the first stage, while in December 2012 an Unha-3 rocket was successfully launched but failed to put its payload - a small satellite - into the correct orbit.
Despite these failures, Sohae is already undergoing a second stage of evolution. Its first incarnation (from 2001 to present) was as a test range developed to launch satellites using the Unha rocket and to perform rocket engine testing. Since 2013, North Korea has made a number of changes to the Sohae site to allow it to operate more efficiently and to launch a wider range of rockets that could relate to the mock-up of a new, larger SLV that was first seen at the Sanum Dong research and development facility, outside Pyongyang, in April 2012.
Imagery of Sohae taken on 3 June 2015 shows that this major construction project is almost complete. If the pad is cleared in August, the assembly and check-out timelines for the two Unha-3 launches in 2012 suggest that a launch could take place in October.
The construction programme at Sohae includes:
1. Raising the height of the gantry tower on the launch pad in 2014 to launch taller rockets while retaining the Unha launch capability.
2. Building a railway line to the Unha launch pad in 2014 to transport a large first stage to the pad for assembly and check-out. The terminus was completed in May 2015 and has a 4 m by 20 m opening into the rail tunnel that will allow the rocket to be lifted onto a moveable trailer on the launch pad.
3. Building a three-storey horizontal assembly building on the east end of the launch pad. The high bay section of the building is 30 m long by 20 m wide and has a single storey section facing the gantry tower. The high bay section has a 10 m long by 5 m high opening in the side that faces the railway tracks.
4. Building a 30 m long by 20 m wide three-storey first stage mover at the gantry tower end of the launch pad. So far three sides of the structure have been completed but when finished it will have a fourth side and probably some type of roof. It is mounted on a platform that moves on rails that run from the gantry tower to the opening in the rail tunnel and the new horizontal assembly building. The mover has a folding section of the floor that allows access to the tunnel opening.
Although the upgrade work will allow the Sohae launch pad to launch larger rockets, it is probable that the pad will still retain the capability to launch Unha-series SLVs. North Korea has previously announced that there will be six more Unha launches up to Unha-9.
Other upgrade work at Sohae appears intended to obscure activities on the ground. For example, work to cover the rail spur will complicate external observation and may make estimates of future SLV launches, of all sizes, more difficult.
"North Korea is working hard to test the rocket engine," the source said, "in addition to a construction project to extend a launch tower at a facility.
There was intelligence that Kim Jong Un as National Defense Commission First Chairman ordered the launch of an artificial satellite, so we believe the launch will take place before October."
North Korea is also moving rocket components produced at space factories near Nampo to the Tongchang-ri facility in Cheolsan Gun of North Pyongan Province, for assembly. More frequent movements of trucks near the Tongchang-ri launch site were detected recently, another government source said.
"It appears that the SLV stages and payload can be prepared horizontally in a new launch support building at the end of the pad, then transferred to a movable support structure that is several stories high, where they will be erected vertically, checked out and finally moved to the launch tower," the report said.
Imagery of the facility's engine test stand also showed that preparations were underway, as of July 21, for "an engine test in the near-term," including the presence of a movable crane and probable ground support equipment, the report said.
When asked about the possibility of North Korea conducting a launch around October, the country's deputy chief of mission to the United Nations, Amb. Jang Il Hun, said he does not "rule out any possibility of doing one of these things,"
"I'm sure we'll have a grand celebration," Jang Il Hun, the North Korean ambassador to the United Nations, told reporters on Tuesday in response to a question about a possible launch that would mark the Oct. 10 anniversary of the Workers' Party of Korea.
Satellite imagery expert Tim Brown also notes in the institute's analysis that North Korea recently completed a 240-meter long (787-feet long) shelter to conceal a rail line intended for transporting equipment to the launch pad.
He said it would prevent observation by satellite of rocket-related rail cars and shipping containers.
Earth observation satellite for weather forecast entering final phase
September 14, 2015
The director of the National Aerospace Development Administration (NADA) of the DPRK was interviewed by KCNA Monday as regards the achievements made by its scientists and technicians in the field of outer space development on the occasion of the 70th founding anniversary of the Workers' Party of Korea (WPK). He said:
The NADA is pushing forward at a final phase the development of a new earth observation satellite for weather forecast, etc. positively conducive to the development of the nation's economy and made big progress in the research into the geostationary satellite, a new higher stage in the development of satellite.
Successful progress made in reconstructing and expanding satellite launching grounds for higher-level satellite lift-off has laid a firm foundation for dynamically pushing ahead with the nation's development of space science.
Space development has become a worldwide trend and many countries are manufacturing and launching satellites for various purposes including communication, global positioning, crop estimate, meteorological observation and resource prospecting.
The world will clearly see a series of satellites soaring into the sky at the times and locations determined by Korea.
