Today (21st) at 8 o'clock, the news starts at the Naro Space Center in Goheung, Jeollanam-do. The Korean launch vehicle 'Nuriho' made with our technology soared into space at 5 PM. Although everything seemed to be going smoothly, the target altitude of 700km was approached, but the satellite model was not able to enter the desired orbit. Just one step wasn't enough. An unfinished success, in fact, more than half the success.



This is the first news reporter Lee Hyun-jung.



<Reporter> With a



roar that shakes the ground, the Nuri-

ho

soars into the sky with flames.



At 5 pm today at the Naro Space Center in Goheung-gun, Jeollanam-do, a Korean launch vehicle made with pure Korean technology took the first step.



The Nuri, which escaped the atmosphere within 2 minutes of launch, succeeded in separating the first stage rocket, the first gateway, at an altitude of 59 km, and flew faster and higher with a lighter weight.



After successfully removing the 'pairing' that surrounds the satellite, the Nuri-ho safely separated even the second stage rocket.



At 5:12 pm, when the target altitude of 700 km was reached, the last 3rd stage engine also stopped operating.



Three minutes later, the 1.5-ton 'satellite replica' loaded on the Nuri instead of the 'real satellite' was safely separated.



Even after the launch, cheers were heard when the news that the Nuri had reached orbit in the control building, which was holding their breath and watching the results.



However, analysis of the data revealed that the target altitude of 700 km was reached, but the satellite did not land in orbit.



It was disappointing that the projectile speed was below target and the last three-stage engine didn't burn enough for what it needed.

▶ More than 3-speed engine…

"It turned off 46 seconds earlier than expected"


▶ 'Meaningful failure' The task to be solved before the second launch of the Nuri
