The other 3 CubeSats on this launch are JLC-101-v1-2 (from Justek), KSAT3U (from Kairo Space), and Lumir-T1 (from Lumir).

South Korea’s KSLV-2 rocket set to launch May 24 [dated Apr. 13]

Quote from: SpaceNews

The primary payload is NEXTSat 2, a 180-kilogram technology demonstration satellite developed by the Korea Advanced Institute of Science and Technology (KAIST).

The seven other satellites, all manufactured domestically, are: a 4-kilogram Earth-observation technology demonstration cubesat JLC-101-v1-2; a 10-kilogram cosmic radiation monitoring cubesat Lumir-T1; a 6-kilogram earth observation and weather monitoring cubesat KSAT3U; and SNIPE, a constellation consisting of four 6U cubesats to identify temporal and spatial variation of small-scale plasma structures in the ionosphere and magnetosphere.

"While controlling a helium valve, aerospace engineers found a communications problem between a launch control computer and a launch pad facility control computer," Vice Science Minister Oh Tae-seog said in a briefing held at the Naro Space Center in Goheung. "The valve is OK but the system might matter when it goes into the automatic operation system. So we inevitably canceled the scheduled launch."

...The committee will determine whether South Korea will go ahead with the launch on Thursday.

Some other spacecraft seen separating (assuming not live?), in particular looks like the SNIPES? Or perhaps also interspersed with the Lumir-T1, KSAT3U and JLC-101-v1-2 CubeSats, unsure. Also, not all of these appear to be onboard, with the graphics showing just 5 satellites overall.

Although I'm getting the sinking feeling they may actually be showing KSLV II's F2 separations from last year (?), just to show what this flight's would look like in the absence of live views? The first separation attached below looks like PVSAT, and four 4U Cubesats were released afterwards, but the SNIPES are 4x3U! See last images regarding PVSAT and NEXTSat-2.

Scratch that, the payload stack is visible in the last attached image, and NEXTSat-2's horn is visible on the top of the separated spacecraft in today's coverage, confirming it was indeed showing today's separations, as expected. Looks like there were only 5 CubeSats apart from NEXTSat-2 though, judging from the visible canisters around the main payload, which also appears to fit the timeline graphs.

After launch, the Nuri was put into the target orbit according to the set flight sequence, and successfully separated and settled the next-generation small satellite No. 2.

In the case of the 6 Cube Satellites, which are auxiliary satellites, it was confirmed that the ejection proceeded normally.

I got to see the launch in person about 18 km away from the launchpad. Here's the recording of the event from my camera.

Visibility was terrible for the faraway watchers the day before due to the mist and fine dust, so the one-day delay was a blessing in disguise for me. The overhanging clouds meant that the launcher became invisible just a minute into flight, so I wasn't able to see the stage separation happening.

During this third launch, Nuri launched the next-generation small satellite No. 2 and six cube satellites sequentially at the target altitude.

However, it is presumed that the Toyosaat 3 was not ejected because the signal for opening and closing the ejection pipe door and the acceleration measurement value of the 3rd stage of the Nuri were not confirmed.

Hangwooyeon plans to conduct an analysis to determine the cause.
