Explaining that the cause of the relevant accident is not a big problem in aspect of the reliability of cascade engines and the system, the NADA expressed the stand that it would conduct the third reconnaissance satellite launch in October after thoroughly probing the reason and taking measures.

Given that today's Chollima-1 launch only had an issue with the third stage resulting from unintentional initiation of the flight termination system despite the second stage functioning normally, I'm assuming that the third Chollima-1 launch will not have any issues with the third stage.

SEOUL, Nov. 3 (Yonhap) -- Defense Minister Shin Won-sik said Friday that North Korea may have delayed its plan to make a third attempt to launch a spy satellite to fix technological glitches in the third-stage system with Russian assistance.
North Korea made two botched attempts to put a reconnaissance satellite into orbit in May and August and vowed to try again in October, but it failed to meet its self-imposed deadline.
 
The first attempt failed due to problems in the booster, while Pyongyang's state media blamed the second flight's failure on a flawed third-stage emergency blasting system.

Shin weighed the possibility of Pyongyang's making a third attempt in late November to reflect technological guidance from Russia following the rare summit between North Korean leader Kim Jong-un and Russian President Vladimir Putin in September.
 "North Korea could try again on its own even if it fails, but the launch may have been delayed as Russia provided specific technical guidance (for the satellite). We place more emphasis on the latter," Shin said during his first meeting with reporters since taking office last month.

"There is a possibility of (North Korea's satellite launch) in around late November. We will continue to monitor the situation," he added.

In response to Pyongyang's efforts to put its first spy satellite into space, Shin vowed to boost the South Korean military's surveillance capability to fend off North Korea's advancing missile and nuclear threat.

He disclosed the South Korean military's plan to launch its first indigenous reconnaissance satellite on Falcon 9, U.S. aerospace company SpaceX's two-stage rocket, from Vandenberg Space Force Base in California on Nov. 30, as well as a plan to launch a homegrown solid propellant rocket later this year.

South Korea has condemned Pyongyang's satellite launch as a provocation and violation of U.N. Security Council resolutions banning its use of ballistic missile technology.

Launch has apparently occurred way earlier than planned (after 13:45 UTC-ish) - Japan has once issued a seek-for-shelter alert (like the last 2 times) for Okinawa, which has now been removed after the Japanese government reported whatever was launched flew over towards the Pacific ~13:55 UTC.

N. Korea carries out 3rd satellite launch attempt

https://en.yna.co.kr/view/AEN20231121010052315?section=nk/nk^

"SEOUL, Nov. 22 (Yonhap) -- North Korea launched what it claims to be a military spy satellite southward Tuesday, the South Korean military said, following two failed attempts earlier this year.

The Joint Chiefs of Staff (JCS) said it detected the launch from the Tongchang-ri area on the North's northwest coast at around 10:43 p.m. and the satellite flew over waters west of the border island of Baengyeong."

North Korea “Successfully launched a reconnaissance satellite… entered the orbit accurately”

https://www.yna.co.kr/view/AKR20231122005351504?section=north-korea/

(Seoul = Yonhap News) Reporter Lee Sang-hyun = North Korea announced on the 22nd that the launch of its first military reconnaissance satellite, 'Manrikyeong-1', launched the night before, was successful.

The Korean Central News Agency said on this day, "The State Administration of Aerospace Technology launched the reconnaissance satellite 'Manrikyeong-1' at the West Sea Satellite Launching Complex in Cheolsan-gun, North Pyongan Province, at 22:42:28 on November 21, 2023, using the new satellite carrier rocket 'Chollima-1'. It was mounted on ‘Type 1’ and launched successfully.”

KCNA press release. Seems like NADA has been renamed to NATA.

http://kcna.kp/en/article/q/1eb1892a9d329f7cd348008b6bd315bd.kcmsf

DPRK NATA's Report on Successful Launch of Reconnaissance Satellite

Pyongyang, November 22 (KCNA) -- The National Aerospace Technology Administration (NATA) of the Democratic People's Republic of Korea successfully launched the new-type carrier rocket "Chollima-1" loaded with the reconnaissance satellite "Malligyong-1" at the Sohae Satellite Launching Ground in Cholsan County, North Phyongan Province, at 22:42:28 on November 21, Juche 112 (2023).

The carrier rocket "Chollima-1" flew normally along the preset flight track and accurately put the reconnaissance satellite "Malligyong-1" on its orbit at 22:54:13, 705s after the launch.

The launch of reconnaissance satellite is a legitimate right of the DPRK for strengthening its self-defensive capabilities and it will make a significant contribution to definitely ramping up the war preparedness of the armed forces of the Republic in conformity with the security environment created in and around the country owing to the enemies' dangerous military moves.

Kim Jong Un, general secretary of the Workers' Party of Korea and president of the State Affairs of the DPRK, oversaw the launch on the spot.

He was accompanied by Kim Jong Sik, vice department director of the WPK Central Committee, and Jang Chang Ha, general director of the DPRK General Missile Bureau.

The respected Comrade Kim Jong Un oversaw the launch and warmly congratulated all the cadres, scientists and technicians of the NATA and relevant institutions on having made a great contribution to enhancing the Republic's war deterrent and most correctly and excellently implementing the resolution of the Eighth Congress of the WPK.

The NATA is to present to the 9th Plenary Meeting of the 8th WPK Central Committee a plan for continuing to secure the capability to reconnoiter the south Korean region and the region of operational interest of the DPRK armed forces by additionally launching several reconnaissance satellites in a short span of time. -0-

I suspect this might have been intentional - to avoid salvage of parts by the South Koreans as happened before.

Just be glad that the North Koreans might have done that. Instead of booby-trapping the stage.

As much as Tilley's work is impressively solid, I fear his ideological convictions are misleading him somewhat in recent times. He indeed is repeatedly on record suggesting quite strongly that Luna 25 never left Earth orbit and might have been a Russian ruse, or that it missed lunar orbit insertion... when the crater on the surface is entirely consistent with nominal operations up to when the mission-ending mess-up, ehm sorry, anomaly, happened.

Likewise for this satellite: there appear to be many explanations as to why he can't observe its EM emissions from Western Canada, and other experienced trackers are pointing out as much in response to his statements - yet he seems blinded by the fact that North Korea are the bad guys to entertain the idea reality may not conform to his preconceptions.

Some schemes attempt to preserve phonetics, others orthography. I prefer the latter. Gives more of  a chance of uniquely reconstructing the original spelling.

I do not know the source, but it is consistent with the illustration seen in the background and the blurred real satellite seen in images from Kim Jong Un's visit at the launch site at the first Malligyong-1 launch.
So I am inclined to assume it depicts indeed the Malligyong-1 satellite.

Looking at the photo of the satellite in preparation, I tried to estimate its dimensions.
The height of the golden supports of the no-go-zone must be around 80cm.
So the satellite is approximately 120 cm high and the external diameter of the optical tube on which it rests is of the order of 66 cm.
This corresponds well to an optical tube like Ritchey Chretien of 35 to 40cm in diameter (optical resolution at 500 km of the order of one meter)

Which image? The one with the blue background is from Kim's banquette for the team.

The technical cutaway is from Kim's visit to the site months ago.
