In October of last year, I watched the scene of the launch of the 'Nuri', developed with pure domestic technology, holding my breath.

It failed to put the satellite into orbit, but two days later, the Nuri embarks on its second challenge.

If successful, it will become the world's 7th space power to put practical satellites into space orbit.



Reporter Jung Gu-hee reports.



<Reporter> This



is the third stage that will finally land the satellite at the target altitude of 700km.

It is moved to the assembly building and combined with the body of Nuriho.



Nuriho, which is 47.2m high and 17 stories high, has completed all assembly processes.



We are going to move to the launch site tomorrow (the 14th), but the last variable is the rain forecast for tomorrow.



[Kim Hong-il / Aerospace Research Institute Flight Safety Technology Department: If the road surface is wet, there is a slight incline to move from the launch vehicle and assembly building to the launch pad.

So there are some problems when moving.]



Although the amount of rain expected is not much, we decided to check the weather tomorrow morning and decide whether to move or not in case of an unexpected accident.



If it is determined that there is no problem, the rocket must be moved to the launch pad 1.8 km away, moving slowly at 1.5 km per hour over an hour and a half to avoid straining the fuselage.



When you arrive at the launch site, you will stand tall towards space.



The launch time is likely to be 4:00 pm the day after tomorrow, but the final launch time is determined by comprehensively analyzing the weather conditions and the possibility of colliding space objects.



As the problem of the three-stage oxidizer tank, which was the cause of the failure of the first launch, has been thoroughly compensated, the expectations for a successful launch are even greater.



[Han Young-min / Aerospace Research Institute Korean Launch Vehicle Development Department: There is no place we did not go, so I feel like a child (Nurihoga), and I am very proud.

The secondary projectile also hopes that our six engines will work well.]



Even if the launch succeeds the day after tomorrow, the Nuri's challenge does not end.



In order to increase the reliability of the launch, we plan to continuously launch the projectile four times from next year to 2027.
