The 5th launch of Nuriho was a success.

South Korea headed into space carrying a record-breaking 15 satellites and successfully placed five microsatellite constellations—its core mission—into their planned orbits.

However, at the moment when everyone was certain of success, an unexpected result was announced.

It was confirmed that 'Persat-2,' one of the 10 CubeSats, failed to eject. Although the separation signal was transmitted normally from Nuriho, it was reported that the ejection tube cover did not open, prompting an analysis of the exact cause.

And yet another tension remained: the question of whether the five Neonsat microsatellite constellations, the core mission of the 5th Nuriho launch, would actually succeed in communicating with the ground.

In this edition of "Inspiring Stories from Abroad," we explore the breathtaking moments that spanned from the success of the 5th Nuriho launch to the separation of the 15 satellites, the Persat-2 ejection issue, and the final communication of the five microsatellite constellations, through the eyes of an overseas launch vehicle expert.

Is a perfect success the only true success?

South Korea’s willingness to disclose even the slightest issues without concealment holds a different significance for international experts.
