@Henri K. Dossier intéressant que je vais m’empressais de copié pour le wiki mais sur ta phrase souligné; c'est peut être une  ''Traduction anglais français''... Mais je rappelle que Taïwan depuis 1971 n'est plus vraiment dans les petits papiers de l'ONU;; ;

Si l'on croit aux Américains, le satellite Kwangmyongsong-4 est reparti comme avant et s'est mis à rouler sur son orbite.

North Korea satellite 'tumbling in orbit,' U.S. official says

(CNN)The satellite North Korea fired into space on Sunday is "tumbling in orbit" and incapable of functioning in any useful way, a senior U.S. defense official told CNN.

Sunday's launch of the long-range rocket triggered a wave of international condemnation and prompted strong reaction from an emergency meeting of the U.N. Security Council.

North Korea maintained the launch was for scientific and "peaceful purposes."

South Korea has recovered about 270 pieces of debris, believed to have come from the rocket launch, from the ocean Sunday and is working to analyze the objects, a South Korean Defense Ministry official told CNN.

North Koreans celebrated the country's launch of a satellite into orbit with an official fireworks display Monday night in Pyongyang, state broadcaster KCTV reported.

"We hope that the future of our space technology keeps growing and shines like these fireworks in the sky," an announcer on the North Korean broadcaster said during coverage of the celebrations in the capital.

Yoon Dong Hyun, vice director of the Ministry of the People's Armed Forces, struck a defiant note in a speech at the celebrations, vowing the country would continue developing its aerospace technology in the face of international sanctions. Efforts by other countries to block such an advance were "nothing more than a puppy barking towards the moon," he said.

The United States and other nations widely viewed the deployment of the dual-use technology as a front to test a ballistic missile, especially coming on the heels of a purported hydrogen bomb test last month.

Pyongyang carried out both acts in defiance of international sanctions.

At an emergency meeting Sunday, members of the Security Council "strongly condemned" the launch and reaffirmed that "a clear threat to international peace and security continues to exist, especially in the context of the nuclear test."

It vowed to undertake punitive actions against North Korea, announcing plans to "adopt expeditiously a new Security Council resolution with such measures in response to these dangerous and serious violations," according to a statement read by Venezuela's ambassador to the United Nations after the meeting.

Sanctions already in place against Pyongyang ban it from working with nuclear weapons and ballistic missiles, blacklist certain figures and organizations and prohibit the import of luxury goods.

Si on compare le pas de tir de 2012 et de 2016, on constate qu'il a été rehaussé. C'est probablement pour préparer le lancement de la fusée Unha-9 (maquette à gauche).

Le satellite Kwangmyŏngsŏng-4 semble avoir été stabilisé finalement, selon les sources américaines.

North Korea satellite in stable orbit but not seen transmitting: U.S. sources

WASHINGTON | BY ANDREA SHALAL AND DAVID BRUNNSTROM

North Korea's recently launched satellite has achieved stable orbit but is not believed to have transmitted data back to Earth, U.S. sources said of a launch that has so far failed to convince experts that Pyongyang has significantly advanced its rocket technology.

Sunday's launch of what North Korea said was an earth observation satellite angered the country's neighbors and the United States, which called it a missile test. It followed Pyongyang's fourth nuclear test in January.

"It's in a stable orbit now. They got the tumbling under control," a U.S. official said on Tuesday.

That is unlike the North's previous satellite, launched in 2012, which never stabilized, the official said. However, the new satellite was not thought to be transmitting, another source added.

U.S. President Barack Obama spoke with the leaders of South Korea and Japan by phone on Monday night and reassured them of Washington's support, while also calling for a strong international response to the launch, the White House said.

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

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

The U.N. Security Council has imposed sanctions against North Korea for its nuclear tests and long-range rocket launches dating back to 2006, banning arms trade and money flow that can fund the country's arms program.

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

The report by the U.N. Security Council's Panel of Experts on North Korea, which monitors implementation of sanctions, said there were "serious questions about the efficacy of the current United Nations sanctions regime."

Western diplomats told Reuters that restricting North Korean access to international ports is among the measures Washington is pushing Beijing to accept in the wake of the Jan. 6 nuclear test and the weekend rocket launch.

"PROVOCATIVE, DISTURBING AND ALARMING"

Missile experts say North Korea appears to have repeated its earlier success in putting an object into space, rather than broken new ground. It used a nearly identical design to the 2012 launch and is probably years away from building a long-range nuclear missile, the experts said.

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

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

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

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

The latest North Korea rocket was based on engines taken from its massive stockpile of mid-range missiles based on Soviet-era technology and electrical parts too rudimentary to be targeted by a global missile control regime, experts said.

South Korea's defense ministry believes the three-stage rocket, named Kwangmyongsong, had a potential range of 12,000 km (7,457 miles), Yonhap news agency reported, similar to that of the 2012 rocket and putting the U.S. mainland in reach.

"I suspect the aim of the launch was to repeat the success, which itself provides considerable engineering knowledge," said Michael Elleman, a missile expert at the International Institute for Strategic Studies.

Separately, U.S. National Intelligence Director James Clapper said on Tuesday that North Korea could begin to recover plutonium from a restarted nuclear reactor within weeks.

Clapper said that in 2013, following its third nuclear test, the North had announced its intention to "refurbish and restart" facilities at its Yongbyon nuclear complex.

"We assess that North Korea has followed through on its announcement by expanding its Yongbyon enrichment facility and restarting the plutonium production reactor," Clapper said in prepared testimony to the Senate Armed Services Committee.

De plus, un premier signal aurait été capté par Scott Tilley à l'Ouest du Canada -

Dans l'ensemble ça part plutôt vers du positif pour le moment.

Vu sur un forum aérospatial ce matin -

Astro-notes :

"Cela y est un radio amateur a enfin réussi hier a attraper le très probable signal radio du satellite KMS-4, mais sur la fréquence 465.985 MHz alors
que moi qui y ait passé du temps je n'ai surveillé qu'entre 465.950 & 465.980 ! C'est ballot ...

Le signal était fort, parfaitement audible ce qui veut dire clair et lisible si le radio amateur avait disposé d'un décodeur. Le signal était affublé de son inévitable effet Doppler (prouvant en cela l’existence de l'objet orbital). Le radio amateur n'a pas fait allusion à une quelconque instabilité de fréquence ce qui veut dire que le satellite ne semblait pas tourner sur lui même (?) et si on ajoute que suivant les paramètres orbitaux donnés par le NORAD, ce satellite présente une excentricité modérée on peut ajouter que ce satellite a bien été contrôlé au cours de sa mise en orbite.

Ceci met un terme aux allégations propagandistes Sud Coréenne, et Japonaise niant la mise en orbite du satellite Nord Coréen. Je suis plus modéré pour les USA qui eux disaient qu'un objet avait bien été mis en orbite mais qu'il était silencieux et tournoyait sur lui même. Encore qu'un satellite peut très bien avoir été volontairement placé en orbite affublé d'un mouvement de rotation pour assurer par effet gyroscopique une attitude voulue, puis ensuite par un système mécanique arrêter ce mouvement une fois le satellite correctement mis en orbite."

Au fait, est ce que ce signal annoncé le 12 février est confirmé ?

Déterrage de topic via un article de NK Pro : les inondations récentes dans la péninsule coréenne ont aussi affecté les travaux en cours sur le centre de lancement de Sohae.

J'aime beaucoup leurs images avec glissières, ça montre bien le avant et le après. A priori, ce sont surtout les voies d'accès et les baraquements des travailleurs qui ont été touchés.

Accélération des travaux pour une nouvelle rampe de lancement à Tongchang-ri

https://fr.yna.co.kr/view/AFR20230523001300884

Radio Free Asia a déclaré qu'une analyse des photos prises par le satellite commercial américain Planet Labs le 22 mai du site de lancement de satellites de Sohae situé à Tongchang-ri, dans le comté de Cholsan, dans la province du Pyongan du Nord, montrait les contours de la nouvelle rampe de tir présumée.

Selon RFA, les travaux sont en cours sur un site de forme rectangulaire mesurant 140 mètres à l'horizontale et 40 mètres à la verticale sur la base de lancement de satellites de Sohae. Des images satellite prises le 30 avril ont montré un sol en terre sur le site, mais sur les photos prises le 16 mai, il peut être observé que du béton a été coulé. Six jours plus tard, plusieurs accès importants ont été identifiés, laissant supposer une construction active sur l'ensemble du site.
