North Korea intends to launch "satellite" within week from Aug. 24

TOKYO - The Japanese government said Tuesday it has been notified that North Korea intends to launch a "satellite" between Thursday and Aug. 31 in what is believed to be a rerun of a failed attempt a few months ago.

Pyongyang tried to launch what it called a military reconnaissance satellite into orbit on May 31 but was unsuccessful.

Japanese Prime Minister Fumio Kishida instructed relevant government agencies to analyze North Korea's plan as much as possible and coordinate with the United States and South Korea in urging Pyongyang not to carry out the launch.

The Japan Coast Guard said it was notified in the early hours of Tuesday that North Korea intends to designate three maritime danger zones -- two of which are to the west of the Korean Peninsula, while the third is to the east of the Philippine island of Luzon. The three areas are outside Japan's exclusive economic zone.

The notification came after the leaders of Japan, the United States and South Korea agreed last Friday during a trilateral summit near Washington to boost cooperation in opposing North Korea's rapid development of nuclear and missile capabilities.

I hope the second stage isn't ignited too early by ground controllers.

Underperformance of the third stage? If so, the third stage of the rocket put the satellite into a lower-than-intended orbit, but at least the second stage performed normally.

KCNA press release. They are calling the satellite as "second launch of reconnaissance satellite Malligyong-1", so maybe the name could be "Malligyong 1 F2". The failure was caused by "an error in the emergency blasting system during the third-stage flight", which sounds like the flight termination system was accidentally initiated. North Korea is going to try again in October.

KCNA Report on Accident in Second Launch of Military Reconnaissance Satellite

Pyongyang, August 24 (KCNA) -- The National Aerospace Development Administration (NADA) of the DPRK conducted the second launch of reconnaissance satellite Malligyong-1 aboard the new-type carrier rocket Chollima-1 at the Sohae Satellite Launching Ground in Cholsan County of North Phyongan Province at dawn of August 24, Juche 112 (2023).

The flights of the first and second stages of the rocket were normal, but the launch failed due to an error in the emergency blasting system during the third-stage flight.

The NADA said that it would make clear in a short span of time the reason why the emergency blasting system was operated abnormally.

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. -0-

Why hasn't the Korean Central News Agency released images of the second Chollima-1 launch yet if the second stage of the rocket functioned normally?
