Looks like the first stage exploded (or was detonated?) after stage sep.

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.

Here's the KCTV news announcement, but it only shows the same photos as from KCNA.

What is the canonical transliteration as Jonathan has it as "Cheonlima"?

It depends on whom to ask about the transliteration.

We don't have one single true Korea. No wonder there are multiple conventions in place.

North Korea give their transliterations in their English press releases, so I think that is a good option to use.

#NorthKorea satellite watch... Nothing to report in the 465MHz region of the UHF band.  Over a day of passes with nothing other than terrestrial and the usual ISS and meteorological satellite emissions.

This entire North Korea thing is following the LUNA 25 playbook.  Can't observe it optically and by radio it isn't playing by the 'rules'.  I hypothesis that it's nothing more than propaganda and another EMP FOBS threat/test.

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.

What's the source of that satellite image? Just a guess by a western artist, or actually from a North Korean source?

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)

The propulsion of the first stage is two RD250 (4 nozzles).

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.

That's my preference as well ... hardly a surprise given my hobbies around Old English manuscripts  8)
