I've always been crazy but it's kept me from going insane - WJ.

After Hwasong-15 test, it is almost certain Unha-3 is retired unless they choose to canibalize Hwasong-7's(Rodong's) in case those get replaced by more advanced liquid fuel or solid fuel missile.

Hwasong-15 could possibly without need of 3rd stage put 300kg object into same orbit as Kwangmyongsong 3-2 and 4.

There's a possibility that North Korea might launch a reconnaissance satellite on February 16, the day of the late Kim Jong-il's birth (the official DPRK biography for Kim Jong-il lists his year of birth as 1942, but Soviet records make clear that he was born in 1941).

This is off topic but hopefully not too much of a digression - do you know the reason for the difference?  I would generally assume it’s a propaganda related reason but I can’t imagine what it would be

The launch of Kwangmyongsong-4 was carried out in 2016 ahead of celebrations of the 75th anniversary of Kim Jong-il's birth. It remains to be seen if the DPRK will carry out a space launch to mark Kim Jong-il's birth this month.

Heard this item mentioned on the 9435kHz VOK (Voice of Korea)  shortwave service 28 Feb 2022:

http://www.kcna.kp/en/article/q/a5ed9ba4f90e3e96d0adee0cb2458f43.kcmsf
Cheong Seong-Chang of the Sejong Institute in South Korea speculates that North Korea may launch a spy satellite to mark the 110th anniversary of Kim il-Sung's birth. If the DPRK successfully launches a reconnaissance satellite into orbit this April, it will emulate the USSR in terms of once again mustering the technological capacity to test homegrown military technology despite being hamstrung by the pitfalls of central planning.

Respected Comrade Kim Jong Un Inspects Sohae Satellite Launching Ground

Pyongyang, March 11 (KCNA) -- Kim Jong Un, general secretary of the Workers' Party of Korea and president of the State Affairs of the Democratic People's Republic of Korea, inspected the Sohae Satellite Launching Ground.

Accompanying him were Kim Jong Sik, Jang Chang Ha and other leading officials of the munitions industry and national defence scientific research sectors and officials concerned of the National Aerospace Development Administration.

Going round different parts of the ground, the respected General Secretary set forth a target for modernizing it and the detailed orientation and ways for doing so.

He learned about and evaluated the present state of the ground, and advanced the task to modernize it on an expansion basis so that various rockets could be launched to carry multi-purpose satellites, including a military reconnaissance satellite, in the future. He also set forth the task for building some facilities in the launching ground.

To enable large carrier rockets to be launched there, he assigned the tasks for reconstructing on an expansion basis the launching ground zone and the facilities for the general assembly and trial gearing of rocket and for the trial gearing of satellite, establishing extra facilities for the injection and supply of fuel and modernizing parts of the launch control facility and major technical posts on an expansion basis.

He also gave detailed instructions as regards the matters arising in modernizing the Sohae Satellite Launching Ground on an expansion basis, including the matters of expanding the capacity of the engine ground jet test site, ensuring the convenience of carrier rocket transport, improving the ecological environment around the launching ground and building a grandstand in the safe zone opposite to the launching ground.

He said that the Sohae Satellite Launching Ground is a place associated with the desire of President Kim Il Sung and Chairman Kim Jong Il for a space power and it is a significant place where our state successfully launched artificial satellites twice with its own efforts and technology, true to the lifetime intention of the President and the Chairman. And he stressed that it is the noble duty of our Party and space scientists and technicians in our era to turn the launching ground, associated with our state's great dream and ambition for a space power, into an ultramodern advanced base and a starting line of space conquest for the future suited to the prestige of the DPRK.

Encouraged by his teachings, the officials, scientists and technicians hardened their strong will to turn the Sohae Satellite Launching Ground into the best model suitable for the dignity and prestige of our state by devotedly carrying out the militant tasks set forth by the General Secretary, fully aware of their mission as space pioneers who should surely carry into practice the grand plan of the Party Central Committee for building a space power, true to the behest of the President and the Chairman. -0-

It seems a North Korean ballistic missile test was used to test their photo reconnaisance camera. The last photo shows a ballistic arc at left of screen. The date at the top of the screen is 27 February 2022, which is the date of a recent missile test. Another missile test was conducted on 6 March. Both tests went into the Sea of Japan. The first test had a range of about 300 km and altitude of 600 km. The second test had a range of 270 km and altitude of 560 km.

Respected Comrade Kim Jong Un Inspects National Aerospace Development Administration

Pyongyang, March 10 (KCNA) -- Kim Jong Un, general secretary of the Workers' Party of Korea (WPK) and president of the State Affairs of the Democratic People's Republic of Korea, inspected the National Aerospace Development Administration (NADA).

Accompanying him were Department Director Yu Jin and Vice Department Director Kim Jong Sik of the WPK Central Committee.

The respected General Secretary was greeted on the spot by leading officials of the NADA and the Academy of Defence Science.

Kim Jong Un learned in detail, from leading officials of the NADA, about the process of scientific research and development intended to hit the goals for attainment of space defence science and technology set forth at the 8th WPK Congress and the 4th Plenary Meeting of the 8th WPK Central Committee.

After acquainting himself with the development and preparations of optical photographing equipment, video transmitter and other communication data transceivers and various kinds of sensors and devices for satellite, he heard reports on the results of the major tests recently conducted by the NADA.

He expressed his great satisfaction over the fact that they confirmed the aerospace photographing method, the operating characteristics of high-resolution photographing equipment and the reliability of image transmission system through the recent important tests.

Seeing the vertical and oblique high-resolution images on specific ground regions taken through the major tests, he highly appreciated the successes the NADA has recently made in settling the image composing and processing technology, the ability of processing a large volume of data communication, the accuracy of control command system, the technology of communication encryption, etc., true to the space development policy of the Party.

The development of a reconnaissance satellite takes an important share in attaining the five major goals for developing the defence power set forth at the 8th Party Congress, he said, stressing once again the strategic significance of the reconnaissance satellite in enhancing the war deterrent of the state and the capability of war preparedness.

Saying that the development of reconnaissance satellite is not merely a scientific research work for the development of information-gathering means, but a work for the protection of our sovereignty and national interests, the exercise of the legitimate rights to self-defence and the elevation of national prestige, he stressed that this urgent project for perfecting the country's war preparedness capacity by improving our state's war deterrent is the supreme revolutionary task, a political and military priority task to which our Party and government attach the most importance.

He called on the officials, scientists and technicians in the space and defence science research sectors to successfully accomplish the development of a Korean-style reconnaissance satellite within the period set by the Party Central Committee by getting united and closely cooperating with each other, true to the WPK's policies for aerospace development and national defence development.

The General Secretary also learned about the construction of the Academy of Space Science and a cosmic environment experiment center.

Noting that it is very important to lay a solid material and technical foundation for the field of space science research so as to attain the high sci-tech goal for space conquest set forth by our state, he stressed the need to give more state support to the space science research sector and examine the important measures for its steady development.

He said that it is our Party's important strategic and tactical policy on bolstering the national defence capability to keep a close eye on and distinguish the character of hostile military actions against the DPRK committed by the aggression troops of the U.S. imperialism and its vassal forces in and around the Korean Peninsula and enhance the capability for controlling situation and improve the rapid counteraction capability of the armed forces of the state according to the relevant situations. And he set forth the militant goals related to the development and operation of the reconnaissance satellite in the period of the five-year plan to implement this policy.

He noted that the purpose of developing and operating the military reconnaissance satellite is to provide the armed forces of the DPRK with real-time information on military actions against it by the aggression troops of the U.S. imperialism and its vassal forces in south Korea, Japan and the Pacific. And he said that the Party Central Committee fully supports the decision of the National Aerospace Development Administration on putting a lot of military reconnaissance satellites into diverse sun-synchronous polar orbits in the period of the five-year plan so as to possess the strong capability for gathering intelligence by satellites.

He expressed high expectation and belief that the space and national defence scientific research sectors would demonstrate to the full the heroic mettle of the defence scientific group remaining boundlessly faithful to the Party and revolution by rising up in the scientific and research campaign to thoroughly carry out the strategic plan of the Party Central Committee and making strenuous efforts.

Cherishing in their hearts the militant task set forth by the respected General Secretary, all the officials, scientists and technicians made a pledge of loyalty to defend the great dignity of our state with cutting-edge defence science, greatly encouraged by his deep trust that gives invincible strength. -0-

It's highly likely that NADA conducted in secret tests of a spy camera reportedly intended for the future North Korean spy satellite that Kim Jong-un has mentioned on occasions. It's common for the photographic apparati of spy satellites to be tested in secret.

Launch expected in April 2023...

On December 18, North Korea Space Development Agency (NADA) conducted a test for reconnaissance satellite development at the Seohae Satellite Launching Station.

A spokesperson for the National Space Development Agency said the main purpose was to “evaluate the capabilities of satellite imaging and data transmission systems and ground control systems”.

A satellite payload equipped with 1 color camera with 20m resolution, and a multi-spectral camera, video transmitter, and other supporting equipment  was launched to an altitude of 500 Km.

The National Space Development Agency announced that it would finish preparing the first military reconnaissance satellite by April 2023.

The name "Unha-3" in the thread title was just the codename for the Paektusan-2 the Kwangmyongsong-3 Unit 1 and Kwangmyongsong-3 Unit 2 launches in 2012 (the failed launch of the Kwangmyongsong-2 satellite was called Unha-2) because the name Kwangmyongsong (the official name for North Korea's satellite class) was inscribed on the first stage of the Paektusan-2 rocket used to loft the Kwangmyongsong-4 into orbit. It is possible that the spy satellite mentioned by Kim Jong-un as under development could be an LEO because the DPRK has yet to master the technological knowhow to make a geosynchronous satellite work, and the earliest American and Soviet spy satellites to be launched were low earth orbit spacecraft.

The reason early US and Soviet spy satellites were launched into LEO was NOT because LEO was technologically more accessible than GEO.  It was because LEO is 100 times closer to the ground than GEO and GEO would require optics 100 times larger (and about 10,000 times heavier) than LEO to obtain the same resolution.

High-res optical spy satellites are STILL launched into LEO for the same reason.

I'm willing to bet the North Koreans will use some sort of portable SLV for this launch. Maybe a SLV optimised version of the Hwasong-15 or Hwasong-17 ICBM systems.

From Yonhap News:
Quote
North Korea's development of a high-thrust engine capable of carrying a rocket has provided a "sure guarantee" for the country to launch various satellites into orbit, according to state media Monday.

Pak Kyong-su, vice director of the National Aerospace Development Administration, made the remarks amid speculation the North is likely to put a military spy satellite into orbit by April.

In an interview by the Korean Central News Agency (KCNA) on Sunday on the occasion of the 14th anniversary of the North's accession to the international outer space treaty, Pak said the North has made "steady" progress in the work to develop "multi-functional and high-performance" satellites.

"It succeeded in developing high-thrust engine for carrier rocket and thus provided a sure guarantee for launching various kinds of satellites into relevant orbits," Pak said in an English-language dispatch carried by the KCNA.

This is probably the first instance of a member of North Korea's space agency mentioning the eventual incorporation of the Paektusan rocket engine into a new Unha-type SLV (called Unha-X by Norbert Brugge), because even though the Paektusan engine is used to power North Korea's Hwasong-12 IRBM and the Hwasong-14, Hwasong-15, and Hwasong-17 ICBMs, the Korean Central News Agency until now did not mention any tests of the Paektusan rocket motor for the SLV that reportedly is intended to carry a reconnaissance satellite.

Here's the North Korean press release on NADA's 10th anniversary. I've highlighted the paragraph that might indicate a launch this year.

http://www.kcna.kp/en/article/q/041f78ba4b3ba3c86550085757f020eb.kcmsf

NADA Marks Its 10th Founding Anniversary

Pyongyang, April 1 (KCNA) -- The National Aerospace Development Administration (NADA) in the DPRK marked its 10th founding anniversary.

The NADA, founded on April 1, Juche 102 (2013), is the national aerospace development guidance organ which maps out space development plans and supervises and controls their implementation in a unified way.

It has proudly exercised the DPRK's legitimate right to develop space for the past decade and conducted the space conquer activities in the forefront of building a space power. It has grown into a prestigious organ representing the state in the field of space development.

It is a product of the noble loyalty, ardent patriotic desire and will of the respected Comrade Kim Jong Un to add eternal shine to the exploits of President Kim Il Sung and Chairman Kim Jong Il for building a space power and demonstrate the dignity of the country and nation before the whole world.

The prestigious and proud history of development of the NADA can be unthinkable without the leadership of the respected General Secretary who made his tireless efforts and painstaking devotion to realize the great dream and ambition of the DPRK to build a space power.

The DPRK, which had proudly emerged a satellite manufacturer and launcher through the successful launches of test satellites in 1998 and 2009, succeeded in putting the first practical satellite onto orbit on December 12, 2012 on the basis of the accumulated technology and experience.

At that time, the advance into space was intensified in the world and its structure diversified.

With a deep insight into the requirements of socialist construction and the trend of the times, the respected General Secretary Kim Jong Un initiated the establishment of a powerful state guidance organ to put the development of outer space of the country on a new higher stage and has wisely led the work for its realization.

The Law of the DPRK on Space Development was promulgated and a decision on establishing the National Aerospace Development Administration was adopted at the Seventh Session of the 12th Supreme People's Assembly on April 1, 2013.

After organizing the NADA, the General Secretary initiated the construction of the satellite control center, personally chose its site and solved all problems arising in the construction, thus making sure that the construction was completed in a short span of time.

Saying that the NADA has a very important duty to realize the plan of the Workers' Party of Korea for building a space power, he indicated the orientation and ways for dynamically pushing ahead with the space science research and satellite launch.

In January, 2016 when space scientists were stepping up the preparations for the launch of the second practical satellite, he visited the Satellite Control Center of the NADA again and clearly indicated once again the purpose, significance and importance of satellite launch, saying that it is not a merely scientific and technological work but the very important and responsible work to be conducted for the dignity of the country and nation before the world.

On February 7, 2016, Kim Jong Un personally visited the launching site of the earth observation satellite Kwangmyongsong-4 and guided the whole process of the launch and led it to complete success.

At the Seventh Congress of the WPK, he set forth the important tasks for further developing space science and technology and thus manufacturing and launching more practical satellites, the aggregate and essence of ultra-modern technology.

In particular, he set it as the immediate goal of space development to put the geostationary satellite into space in the near future and made sure that the development of a new-type geostationary satellite carrier rocket was conducted in a positive way.

He, who guided in September 2016 the ground jet test of a high-power engine for the geo-stationary satellite carrier rocket for the first time in the DPRK, highly praised the scientists and technicians for devotedly carrying out in a short span of time the task given by the Party.

While inspecting the NADA in March 2022, he set forth the development of a reconnaissance satellite as the top political and military prior task and the supreme revolutionary task of the Party and the government, and clarified the issues for laying a solid material and technical foundation of the field of space scientific research.

In the arduous struggle to explore and conquer outer space in our own way, he instilled wisdom, strength and courage into the minds of the space developers, always finding himself among them.

Thanks to his energetic and meticulous leadership, a well-regulated guidance and management system for the country's space development was established, all the work for the exploration and use of outer space could be conducted in a unified and far-sighted way, and great successes were registered in the work to design and make practical satellite and develop the satellite control equipment and in other space development work.

Today the NADA is recording great achievements in the efforts to make a multi-functional and highly efficient satellite and boost its reliability.

Lots of scientific and technological problems arising in the satellite control and operation have been solved, and the work to introduce the application technology into the economic construction, the improvement of the people's standard of living and the building up of the country's defence capacity has been stepped up.

The NADA is strengthening the international trust and cooperation in the space science field, strictly observing the international outer space treaty, agreements and conventions.

The officials and space scientists of the NADA, who have turned out in the work to carry out this year's task of the new five-year plan for the national aerospace development with great confidence and courage, are pressing ahead with the preparations for launching and operating new practical satellites of various purposes by their own efforts and technology.

Efforts are also made to apply the space scientific and technological successes to agriculture, fishery, weather observation, disaster monitoring, resources prospecting and the development of communication system of our own style. -0-

I think North Korea can be expected to use the same type of launcher used to launch the Kwangmyongsong-4 satellite, because I've always opined that the DPRK has not yet mastered the technological expertise to manufacture brand new first and second stage technology for a geostationary satellite launcher.

Even if it may be a foregone conclusion that China and Russia will give North Korea a free pass on launching its first reconnaissance satellite because they know that the R-7 Semyorka was used for launching the Sputnik and Vostok spacecraft, the US and South Korea hopefully will revise their messaging about DPRK space launch vehicle development because it is apparent that North Korea's space launches were designed to convey a message to the North Korean people about the DPRK having become technologically advanced despite so many years of famine and economic lethargy.

Here's the official press release. I've bolded the section that says that a military photo reconnaissance satellite is to be launched no earlier than this month. There were also some photos, but most of the good bits had been blurred out! However, as the photos were in high resolution some portions were not blurred where we presumably get a good view of what the satellite looks like! It looks to be hexagonal shaped with four solar panels at top.

Photo 7 shows a hexagonal satellite with two visible sides covered in solar panels and one side side not covered. This could be a model of the hexagonal satellite shown in the launch control centre, with the solar arrays in their launch position. There is also a rectangular satellite next to this satellite. This photo also shows what looks like a geosynchronous communications satellite hanging from the ceiling.

Respected Comrade Kim Jong Un Inspects NADA

Pyongyang, April 19 (KCNA) -- Kim Jong Un, general secretary of the Workers' Party of Korea (WPK) and president of the State Affairs of the Democratic People's Republic of Korea, inspected the National Aerospace Development Administration (NADA) on April 18.

He was accompanied by Pak Thae Song, secretary of the WPK Central Committee, Kim Jong Sik, vice department director of the WPK Central Committee, Kim Sung Chan, president of Kim Il Sung University and minister of Higher Education under the Education Commission, Pak Ji Min, president of Kim Chaek University of Technology, senior officials of educational and scientific research institutions, technicians and experts in the field of IT communication sci-tech studies and commanding officers of the technical intelligence department of the General Reconnaissance Bureau of the Korean People's Army.

He was greeted by leading officials of the NADA and the Academy of Defence Science on the spot.

Going round the space science research institute, the space environment test center and other places, he learned in detail about the work for fulfilling the immediate scientific research tasks set forth by the Party's far-reaching space-conquering policy on the long-term development of the country's space industry, and about the recent progress achieved by the field of space science research in the development of core technologies and production.

The respected Comrade Kim Jong Un highly praised the noteworthy achievements made by the NADA in the core space sci-tech studies to attain the immediate and long-term objectives of the space policy set forth at the 8th Congress of the WPK, the 5th and 6th Plenary Meetings of the 8th WPK Central Committee.

Noting that the development of space industry is of very important significance in building a socialist economic power whose development is propelled and guaranteed by science and technology, he set forth the important tasks to be fulfilled to radically develop space science and technology.

The growth of the space industry is a key element in the exploration of a shortcut to securing the position of a world-class economic and sci-tech power and a demonstration of the overall national power, he said, adding that it is necessary to build a full-fledged space industry capable of dynamically steering the economic development of the country by constantly spurring the independent space development.

He noted that it is the steadfast stand of the WPK and the DPRK government to fulfill on a priority basis the advanced and valuable space development plans in the light of the strategic interests of the country in the present-stage efforts for achieving accelerated space development, steadily expand the successes and finally turn the country into a world space power.

He underscored the need to set it as a main thrust to possess weather and earth observation and communication satellites, in particular, to get thoroughly prepared for the disastrous weather, effectively protect and use the resources of the country, and immediately provide the possibilities for giving strong impetus to the scientific development of the national economy.

He also called on the educational and scientific research units at all levels to establish a system of actively participating in the development of application satellites of various uses, increase state investment for promoting the development of space science and technology, produce standardized and reliable carrier rockets on a full scale in step with the accelerated development of various satellites, and successfully build satellite launching sites reflecting the ideal and ambition for building a space power.

He recalled that in the light of the present situation, in which the U.S. imperialists are deploying nuclear carriers, nuclear strategic bombers and other huge strategic assets of various missions on a permanent basis on the Korean peninsula and its vicinity to turn south Korea into an advanced base for aggression and an arsenal for war, and of the prospective concern that the military actions of the U.S. and south Korea threatening the sovereignty and territorial integrity of the DPRK under the pretext of the allied readiness would get more undisguised, the Eighth Congress of the WPK specified it as the most important and prerequisite task for building up the national defence capabilities of the country to have access to the space reconnaissance capability for securing real-time information about the hostile forces' military scenario and moves in the five-point major goals for developing the national defence capabilities.

Again referring to the role and the strategic value and significance of possessing the military reconnaissance satellite in bolstering up the self-defensive military capabilities for defending the security environment and territorial integrity of the state, the safety and development interests of the people from the escalating military threat and challenge of the U.S. and south Korea, and for using the preemptive military power according to situation, he said that possession of such satellite is a primary task to be indispensably fulfilled to bolster up the armed forces of the DPRK that can never be abandoned, missed and changed, and belongs to its sovereignty and legitimate right to self-defence in view of the requirements of the recent security environment on the Korean peninsula and tackling of the long-term threats.

As the U.S. and south Korea are scheming to further tighten their military posture against the DPRK under the pretext of "offer of extended deterrence" and "strengthened south Korea-U.S. alliance", as evidenced by their most hostile rhetoric and explicit action this year, it is quite natural for the DPRK to develop its military deterrence strong enough to cope with the serious security environment at present and in the future, he said, adding that possessing and operating military reconnaissance means is the most crucial primary task for increasing the military effectiveness and utility of different war deterrence means of the DPRK in doing so.

He set forth the militant task to organize a non-permanent satellite-launching preparatory committee to make sure that the military reconnaissance satellite No. 1 completed as of April will be launched at the planned date, speed up its final preparations and firmly establish the satellite intelligence-gathering capability by deploying several reconnaissance satellites on different orbits in succession in the future.

Upon receiving the deep trust and encouragement of the respected Comrade Kim Jong Un, the officials, scientists and technicians of the NADA were filled with a firm determination to become conquerors of space faithfully upholding the Party's far-reaching plan for building a space power through their perfect practice and thus proudly demonstrate the dignity and prestige of the DPRK and the great national power of Juche Korea in the outer space. -0-

The satellite with its deployed solar arrays hanging from the ceiling of the NADA headquarters is quite sophisticated and possibly could be the kind of geostationary satellite mentioned by Kim Jong-un on a few occasions because the two satellites that North Korea has orbited were designed for low earth orbit and the soon-to-be-launched DPRK spy satellite is almost certainly intended to spy on enemy territory from sun-synchronous orbit.

Below is the Rodong Sinmum press release from May 17, 2023, regarding technical preparations for the DPRK's first launch of a spy satellite.

https://kcnawatch.us/newstream/1684271609-417387641/%EA%B2%BD%EC%95%A0%ED%95%98%EB%8A%94-%EA%B9%80%EC%A0%95%EC%9D%80-%EB%8F%99%EC%A7%80%EA%BB%98%EC%84%9C-%EC%A0%95%EC%B0%B0%EC%9C%84%EC%84%B1%EB%B0%9C%EC%82%AC%EC%A4%80%EB%B9%84%EC%9C%84%EC%9B%90/

Respected Comrade Kim Jong-un guided the work of the Reconnaissance Satellite Launch Preparation Committee on the spot

While the struggle to strengthen self-defensive defense capability to achieve the five key goals for national defense development presented by the 8th Congress of the Workers' Party of Korea is being vigorously developed, The Non-Standard Satellite Launch Preparation Committee for the launch of Military Reconnaissance Satellite Unit 1, which includes scientists and technicians, is vigorously promoting its business in the solidarity stage.

Respected Comrade Kim Jong Un, General Secretary of the Workers' Party of Korea and Chairman of the State Affairs Commission of the Democratic People's Republic of Korea, guided the work of the Non-Standard Satellite Launch Preparation Committee on-site on May 16.

The respected comrade Kim Jong-un was greeted by key officials of the Ministry of Munitions Industry and the Ministry of Science and Education of the Central Committee of the Workers' Party of Korea, as well as members of the Space Development Bureau and the Emergency Satellite Launch Preparation Committee.

Respected Comrade Kim Jong-un studied the business conditions of the Non-Standard Satellite Launch Preparation Committee in detail and looked around the military reconnaissance satellite No. 1.

Respected Comrade Kim Jong-un highly appreciated the fact that the Non-Standard Satellite Launch Preparation Committee is fulfilling its duties and roles responsibly in the process of carrying out an important project to dramatically increase the country's military technology.

Respected Comrade Kim Jong-un said, “The successful launch of a military reconnaissance satellite is an urgent request starting from the established national security environment, an accurate implementation process of the DPRK government’s top priority policy of strengthening national defense, and at the same time, the country’s space military and science and technology Saying that it is a clear step forward in development, he specifically clarified the strategic goals to be continuously achieved in the field of space research.


Dear Comrade Kim Jong-un, while emphasizing again and again the strategic nature of possessing military reconnaissance satellites, the more heinous the anti-DPRK confrontation maneuvers of the US imperialists and the south Korean puppet villains become, the more our sovereignty and self-defense right to thoroughly suppress them and defend the country He said it would be exercised more confidently and more aggressively.

Respected Comrade Kim Jong Un approved the future action plan of the Non-Standard Satellite Launch Preparation Committee.

Its looks to be in the same weight/size class as Kwangmyongsong-4. Return of Unha-3 maybe? There has been rapid work at the launch pad at Sohae since late April (https://www.38north.org/2023/05/sohae-satellite-launching-station-launch-pad-construction-resumes/) so it might be ready to support a launch campaign in coming months.

Unha-3 was the DPRK codename for the Paektusan-2 rocket used to launch the Kwangmyongsong-3 satellites, while the Paektusan-2 rocket that launched the Kwangmyongsong-4 satellite bore the writing "Kwangmyongsong" on the first stage. As noted in a 2008 monograph The North Korean Ballistic Missile Program, a June 2006 issue of the pro-DPRK newspaper Choson Sinbo cited official North Korean sources as saying that Paektusan-2 is the official name for the North Korean SLV known by US intelligence as the Taepodong-2 that had its unsuccessful first launch in July 2006 (most probably a suborbital test), so Paektusan-2 may well be the appropriate name for the SLV used for the 2009, 2012, and 2016 satellites and the upcoming reconnaissance satellite launch.

Thanks to a tip from @martyn_williams I took a look at the warning areas for the upcoming (NET May 31) North Korean recon sat launch.
  The map below shows the launch site, polygonal warning areas and (orange lines) my fit to the trajectories.   (1/n)...

Quote
I think the first and second warning areas correspond to first stage and nose fairing impact zones, and correspond to a -5650 x 150 km x 93.9 deg (sub)orbit  (apogee not well constrained).

Quote
Then the second stage makes a 'dog leg' yaw change to head southeast, firing at 1st stage apogee to a -5240 x 500 km x 75.7 deg orbit with impact east of the Phillipines. This trajectory has an apogee over 127.1E 26.1N.

Quote
The third stage will fire at second stage apogee, likely to reach a 500 x 500 km x 76 deg orbit. The reason for the change in direction is to avoid flying over S Korea during the launch.
But the reason for a 76 deg final orbit is unclear to me.

Quote
The third stage will need a delta-V of 3550 m/s to match the trajectory I derive and reach a circular orbit. This is a pretty normal value. For example, a solid upper stage of Isp 270s could orbit a 250 kg sat and 50 kg empty stage with 850 kg of propellant, all plausible nos.

The planned trajectory of the North Korean satellite launch, as estimated by me based on debris warning areas, passes 500 km above the Okinawa region - higher than the International Space Station. The only landmass it goes directly over is the uninhabited island of Irisuna-jima.

Quote
It is possible that the second stage could shut down early, or that the yaw manuever prior to stage 2 ignition could go off course, so it is not completely *impossible* for debris from the launch to hit the Okinawa region. But it is very, very unlikely.

Quote
Thus, I consider Japanese goverment hyperventilation about the launch to be rather excessive.

Quote
This side-on illustration shows the second and third stage planned trajectories; you can see that the planned path is way out in space as it passes over Okinawa

The launch may have failed.

https://www.japantimes.co.jp/news/2023/05/31/national/north-korea-missile-satellite-okinawa-alert/

"Our military is trying to confirm whether it flew normally," the military said in a statement. An unidentified source separately told Yonhap that Seoul was analyzing the possibility that the rocket had exploded in midair or crashed.

Tokyo was also looking into the possibility that the launch may have failed as Prime Minister Fumio Kishida and top officials gathered to be briefed on the launch.

Unidentified government sources told NHK that the launch failed on the western side of the Korean Peninsula over the Yellow Sea without putting any payload into orbit.

The Korean Central News Agency has issued the following report on the failed launch of Malligyong-1:
Quote
KCNA Report

Pyongyang, May 31 (KCNA) -- The Korean Central News Agency (KCNA) made public the following report on Wednesday as regards an accident occurred during the launch of military reconnaissance satellite:

The National Aerospace Development Administration (NADA) of the DPRK launched a military reconnaissance satellite, "Malligyong-1", mounted on a new-type carrier rocket, "Chollima-1", at the Sohae Satellite Launching Ground in Cholsan County of North Phyongan Province at 6:27 on May 31, Juche 112 (2023), as scheduled.

The carrier rocket "Chollima-1" fell to the West Sea of Korea after losing thrust due to the abnormal starting of the second-stage engine after the separation of the first stage during the normal flight.

The NADA spokesperson attributed the failure to the low reliability and stability of the new-type engine system applied to carrier rocket "Chollima-1" and the unstable character of the fuel used, saying that scientists, technicians and experts concerned start discovering concrete causes.

The NADA said that it would thoroughly investigate the serious defects revealed in the satellite launch, take urgent scientific and technological measures to overcome them and conduct the second launch as soon as possible through various part tests.

Images from the first tweet. The vehicle looks to be liquid fuelled. The brown covering could be insulation, perhaps indicating a cryogenic propellant, perhaps liquid oxygen.

Was the name "Kwangmyongsong 5" ever given by North Korean sources, or was this just an assumption before the satellite was launched?

The name Kwangmyongsong 5 was coined by Gunter's Space Page for a speculative satellite launch by the DPRK based on news reports from late 2017:
https://space.skyrocket.de/doc_sdat/kwangmyongsong-5.htm

In any case, the Korean Central News Agency report puts to rest the question of what the first completed DPRK reconnaissance satellite would be christened. It's also interesting to note that the Chollima-1 SLV involved in the launch is named after Chollima, a winged horse from East Asian mythology, and the Chollima Movement engineered by North Korea in the late 1950s to foster rapid economic growth in the country.

From the Yonhap News Agency:
Quote
SEOUL, May 31 (Yonhap) -- North Korea's launch of a "space launch vehicle" may have failed due to a technical problem caused by "excessive change of the projectile's route," South Korea's spy agency said Wednesday.

The National Intelligence Service (NIS) delivered this information during a briefing to the parliamentary intelligence committee.

Earlier in the day, Seoul's Joint Chiefs of Staff said it detected the launch from Tongchang-ri on the North's west coast at 6:29 a.m. The projectile then flew over the waters far west of the South's border island of Baengyeong before falling into waters some 200 kilometers west of the southwestern island of Eocheong, it said.

The North confirmed the failure, saying its new "Chollima-1" rocket carrying a military reconnaissance satellite, "Malligyong-1," fell into the sea due to the "abnormal starting of the second-stage engine."

"The NIS report suggested a technical glitch may have occurred because the projectile was set up to fly a route leaning toward the west but had to make an excessive change of route toward the east through lateral motion," Rep. Yoo Sang-bum of the ruling People Power Party told reporters after the closed-door briefing.

The agency also cited the North's premature launch as possibly being connected to the failure.

North Korea shortened the preparation period and fired its projectile from the launch center in Tongchang-ri, which has not been fully constructed, after South Korea successfully launched its homegrown space rocket Nuri last week, according to the NIS.

It also said North Korean leader Kim Jong-un is assumed to have observed the launch in person from a nearby place since vehicles and tents for spectators were identified near the observation deck, located 1.3 km away from the launch site.

The "Chollima-1" rocket is assessed to be a new type of projectile using an engine for intercontinental ballistic missiles, while the "Malligyong-1" is a 1.3 meter-long small low-orbit satellite weighing 300 kilograms that can only conduct basic reconnaissance activities, Yoo said.

If the second stage engine malfunctioned due to an unintentional route change, the possibility that there was some electrical mishap that caused the second stage engine to go out seconds after ignition can't be ruled out.

not true.  trajectory or guidance issues are not going to cause electrical problems.

The Korean Central News Agency has released images of the first launch of the Chollima-1 SLV:

Judging from comparison with the Paektusan-1 and Paektusan-2 used in North Korea's first five satellite launches, the Chollima-1 bears resemblance to the Falcon 9 and Atlas V in the diameter of the first and second stages as well as the size of the payload fairing.

Not happy Jan! Looks like Chollima-1 was launched from their new site, which features a horizontal integration building and launcher transporter to the pad. Looks like the first stage has four engines. The lack of frost on the first stage and colour of the exhaust indicates storable N2O4/UDMH type propellant. The vehicle has an interesting colour scheme with the first stage being grey with some white checkers, while the second and third stages are white with some grey checkers. The second and third stages have a smaller diameter than the first stage.

Kim Yo Jong, Vice Department Director of C.C., WPK Releases Press Statement

Pyongyang, June 1 (KCNA) -- Kim Yo Jong, vice department director of the Central Committee of the Workers' Party of Korea, issued the following press statement titled " No one can deny the DPRK's sovereign right to satellite launch" on June 1:

The U.S. is openly revealing its inveterate hostility toward the DPRK over its military reconnaissance satellite launch belonging to its right to self-defence.

A spokesperson for the National Security Council of the White House on Wednesday clamored that all countries should denounce the DPRK's military satellite launch, saying there is a danger of unnecessarily escalating tension and destabilizing the regional security as it is an open violation of the UNSC's "resolution".

It is neither surprising nor new, but the U.S. is letting loose a hackneyed gibberish prompted by its brigandish and abnormal thinking.

Who is escalating the tension unnecessarily and destabilizing the regional security situation?

If the DPRK's satellite launch should be particularly censured, the U.S. and all other countries, which have already launched thousands of satellites, should be denounced. This is nothing but sophism of self-contradiction.

The far-fetched logic that only the DPRK should not be allowed to do so according to the UNSC's "resolution" which bans the use of ballistic rocket technology irrespective of its purpose, though other countries are doing so, is clearly a gangster-like and wrong one of seriously violating the DPRK's right to use space and illegally oppressing it.

It is pitiful that the U.S.-style gangster-like logic was stipulated in the UNSC's "resolution".

The U.S. is a group of gangsters who would claim that even if the DPRK launches a satellite in space orbit through balloon, it is illegal and threatening.

It is the "tragedy of the U.S." in the 21st century that it can never give a correct answer with a wrong formula and has not discarded misunderstanding of it.

The U.S. should cool its head heated with confrontation hysteria and clearly look into the UN Charter and the provisions of the space treaty once again before groundlessly denying and pulling up a sovereign state over its satellite launch and its right to space development.

Even at this moment, the U.S. is absorbed in watching every movement of the DPRK with sharp eyes after flying a lot of reconnaissance satellites, high altitude unmanned reconnaissance planes and all other reconnaissance assets in the sky above the Korean Peninsula. It is just like a guilty party filling the suit first and illogical to pull up the DPRK over its military reconnaissance satellite launch.

The U.S. should no longer illusion nor be overconfident itself.

No one vested the U.S. with the authority to take issue with the sovereign right of a specified state.

Taking this opportunity, we would like to once again clearly warn the U.S., which trying to blind and deafen the eyes and ears of the international community with such honeyed dialogue ballad as "door of diplomacy" and "sincere negotiation".

We have no content of dialogue and do not feel the necessity of dialogue with the U.S. and its stooges that oft-repeat the "end of regime" and the "overthrow of system". We will continue our-style way of counteraction in a more offensive attitude so that they should not but realize that they will have nothing to benefit from the extension of the hostile policy toward the DPRK and how dangerous their pursuit of confrontation with the DPRK is.

We are ready to act whatever it may be in defending its sovereign right and interests.

Reading the psychology of the U.S. and its stooges, that are so uneasy about the DPRK's military reconnaissance satellite issue, we confirmed once again that the enemies are most afraid of the DPRK's access to excellent reconnaissance and information means including reconnaissance satellite and, accordingly, we are aware that we should direct greater efforts to developing reconnaissance means.

It is certain that the DPRK's military reconnaissance satellite will be correctly put on space orbit in the near future and start its mission.

We are well aware of the protracted nature of the confrontation with the U.S. and will make all efforts to bolster up war deterrent in an all-inclusive direction, being conscious of the long-term threats and challenges.

If the U.S. and its stooges continue to commit rash acts of infringing upon our sovereign right, we will never remain an onlooker to them. -0-

From the videos above, there were some photos that I hadn't seen before as well as one photo that was less cropped. One photo gives a good view of the clean room, showing that it could handle much larger satellites. Anybody wants to translate the propaganda written on the wall?

Steven looking at the two pictures, the one seems to indicate the transporter Eractor got toasted and maybe destroyed during launch.

In the second picture, I question the Area One cloud compared to the Area Two clouds that appear to be actual exhaust as it's lifting upwards.  Area-One exhaust appears to be clouds that were injected over the water to make it appears to be a larger rocket blast.

The rocket image is heavenly pixelated to analyze the surface, but based on the Gray painted patterns, I'm taking a guess that the floating stage from the South Koreans could be the top of the second stage

I was surprised by the appearance of the new launch vehicle. I'd assumed it was simply another Unha iteration/derivative but it's completely different.

Looks like they recovered the second stage. Interestingly, the interstage between the first and second stage is still attached along with the top part of the first stage. Perhaps there was some kind of separation failure.

North Korea's 'space launch vehicle' 2nd stage salvaged from the West Sea last night
North Korea's 'space launch vehicle' 2nd stage salvaged from the West Sea last night

(Seoul = Yonhap News) The wreckage of the Chollima Type 1 space launch vehicle launched by North Korea using ballistic missile technology was recovered 15 days after it fell into the West Sea. The photo shows the remains of a projectile released by the Joint Chiefs of Staff. 2023.6.16 [Provided by the Joint Chiefs of Staff. Resale and DB prohibited] [email protected]

(Seoul = Yonhap News) Reporter Park Soo-yoon = It is known that the military authorities recently salvaged an object believed to be a military reconnaissance satellite that North Korea failed to mount on a space launch vehicle at the end of last month.

According to a military source on the 26th, the Navy rescued an object that appeared to be a satellite 'Malligyeong-1' mounted on a space launch vehicle 'Chollima Type 1' launched by North Korea using ballistic missile technology on the 31st of last month in the high seas of the West Sea last week.

A military source said, "I understand that various wreckage has been collected from the site," and "the salvage operation and related activities are continuing."

The military moved the estimated satellite object to the Defense Science Research Institute (ADD) in Daejeon and began analysis.

If this object is hit by a satellite and is relatively intact, it seems that the level of North Korea's reconnaissance satellite technology can be identified in detail.

A space launch vehicle launched by North Korea on the 31st of last month from Dongchang-ri, North Pyongan Province crashed into the West Sea after the first and second stages separated, and in the process, about 180 pieces of debris were captured by an Aegis destroyer and Air Force radar.

Military authorities salvaged the second-stage fuselage on the night of the 15th, but could not find the mounted satellite.

The South Korean and U.S. military authorities are jointly analyzing the two-stage fuselage and objects suspected of being reconnaissance satellites.

On the Korean side, experts from the Ministry of National Defense, Joint Chiefs of Staff, Navy, and ADD are participating in the analysis, and on the US side, personnel from various organizations such as the Defense Intelligence Agency (DIA) under the Ministry of National Defense are participating in the analysis.

Here's a link to the article with the relevant paragraph.

https://en.yna.co.kr/view/AEN20230705001752325?input=tw

"South Korea has retrieved a North Korean spy satellite wreckage and concluded it has "no military utility," Seoul's military said Wednesday, ending a 36-day operation to salvage the sunken debris from a failed North Korean space rocket launch in late May."
