A rocket carrying the satellite blasted off Tuesday night from North Phyongan province, flew along its designated path and "accurately put the reconnaissance satellite 'Malligyong-1' on its orbit," state-run news agency KCNA reported.

North Korean leader Kim Jong Un was on hand to witness the blast off, and congratulated the scientists and technicians behind the mission, it added.

The United States quickly led condemnation of the launch as a "brazen violation" of UN sanctions and said it could destabilize the region.

South Korea reacted by saying it would resume surveillance operations along the border with North Korea that had been suspended in 2018 as part of a Seoul-Pyongyang agreement to reduce military tensions, the Yonhap news agency reported.

North Korea's previous efforts to put a spy satellite into orbit in May and August both failed. Seoul, Tokyo and Washington had repeatedly warned Pyongyang not to proceed with another launch, which would violate successive rounds of UN resolutions.

Space launch rockets and ballistic missiles have significant technological overlap, experts say, but different payloads, and Pyongyang is barred by UN resolutions from any tests involving ballistic technology.

Seoul's spy agency this month said Pyongyang appeared to have received technical advice from Russia, in return for sending at least 10 shipments of weapons for Moscow's war in Ukraine.

KCNA said after this mission that "the launch of reconnaissance satellite is a legitimate right of the DPRK for strengthening its self-defensive capabilities" as the country confronts what it calls threats from South Korea and the United States. DPRK (Democratic People's Republic of Korea) is the official name for North Korea.

The North plans to launch more satellites "in a short span of time" to step up its surveillance capability on South Korea, KCNA said.

South Korea's Joint Chiefs of Staff said it was analyzing the launch and did not confirm if the satellite had in fact been placed in orbit.

"North Korea's military satellite launch constitutes a provocative act that blatantly violates the UN Security Council resolutions prohibiting its use of ballistic missile technology as well as scientific and technological cooperation," the JCS said in a text message to reporters.

- 'Confidence in success' -

Seoul has been saying for weeks that Pyongyang was in the final stages of preparation to launch another spy satellite, warning it would take "necessary measures" if it went ahead.

The North's May attempt failed due to the "abnormal" startup of its second-stage engine, and the August bid due to an error in the "emergency blasting system" during the third-stage flight, according to Pyongyang state media at the time.

Tuesday's "launch that came hours before its time window notification seems to underscore two things: Pyongyang's confidence in success and intention to maximise surprise factor to the outside world," Choi Gi-il, professor of military studies at Sangji University, told AFP.

Russian President Vladimir Putin suggested in September after meeting with North Korean leader Kim Jong Un that his nation could help Pyongyang build satellites.

Seoul and Washington have both subsequently claimed Pyongyang has been shipping weapons to Russia, with US Secretary of State Antony Blinken warning this month that military ties between North Korea and Russia were "growing and dangerous".

Successfully putting a spy satellite into orbit would improve North Korea's intelligence-gathering capabilities, particularly over South Korea, and provide crucial data in any military conflict, experts say.

North Korea has conducted a record number of weapons tests this year.

Seoul, Washington and Tokyo have ramped up their defence cooperation in response, and on Tuesday a US nuclear-powered aircraft carrier, the USS Carl Vinson, arrived at South Korea's Busan Naval Base.

US 'strongly condemns' N. Korean space launch
Washington (AFP) Nov 21, 2023 - The White House on Tuesday strongly condemned North Korea over its space launch, calling it a "brazen violation" of UN sanctions that could destabilize the region.

The launch "raises tensions, and risks destabilizing the security situation in the region and beyond," National Security Council Spokesperson Adrienne Watson said in a statement.

North Korean state media reported early Wednesday local time that the country had succeeded in putting a reconnaissance satellite in orbit.

A rocket carrying the satellite blasted off Tuesday night from North Pyongan province, flew along its designated path and "accurately put the reconnaissance satellite 'Malligyong-1' on its orbit," state run news agency KCNA reported.

Watson stressed that the launch involved technologies that are "directly related" to the North's ballistic missile program, and which Pyongyang is banned from testing by multiple UN Security Council resolutions.

"The door has not closed on diplomacy but Pyongyang must immediately cease its provocative actions and instead choose engagement," the statement said.
