Navigational Warnings (HYDROPAC 1800/24) have appeared for a new North Korean satellite launch, the launch of their second military reconnaissance satellite Malligyong-2, from Sohae. North Korea also informed the Government of Japan of the upcoming launch.

The three hazard areas A to C  from the Navigational Warning are the same as those for the Malligyong-1 launch half a year ago (21 November 2023 - see this earlier blogpost). Quite likely therefore, the launch will go into a similar 97.4 degree inclined, 512 x 493 km Sun-synchronous orbit. Stage 2 and stage 3 will do a double dogleg.The launch window runs to June 3.

It will be interesting to see what the RAAN of the orbital plane will be in relation to that of Malligyong-1.

UPDATE: further speculation as to what could be the launch time in a follow-up post here.

UPDATE 2:  launch was near 13:50 UTC (May 27, 2024) and failed due to in-flight explosion of the first stage.

UPDATE 3: The North Korean State Press Agency KCNA calls the satellite in the failed launch "Malligyong-1-1" and indicates first stage failure caused the mishap, related to the "reliability" of a new LOX + petroleum engine. The wording is somewhat ambiguous on whether it concerns a new kind of rocket or a Chollima-1 stage: they do not name the rocket type, but mention a "new-type satellite carrier rocket" . 

It should be noted that during the previous Malligyong-1 launch, the Chollima-1 first stage also blew up, somewhat after separation of the second stage (so it did no harm to the payload at the time). Here is footage of that occasion.
