Korean launch vehicle Nuri, using only our own technology, failed to put the satellite into orbit. The attempt today (21st) failed, but we plan to start preparing again with the goal of the second launch in May next year. 



This is the first news reporter Park Chan-geun.

At 5 pm, the first Korean projectile, the Nuri, starts a great flight, emitting flames with vibrations that resonate the earth's axis.



It flew straight into the sky, emitting bright flames over the Naro Space Center.



It didn't show any particular anomalies until it was out of sight, but it never got back on track.



Just an hour and a half before the scheduled launch, the Aerospace Research Institute was careful by delaying the scheduled time by one hour.



[Yong Hong-taek / First Vice Minister of Science and Technology Information and Communication: The launch was originally scheduled to be launched at 4 pm, but it took additional time to check the launch pad subsystem and valve.]



However, the launch failed and unfortunately, the next one was promised.



The success or failure of the Nuri was judged within 16 minutes.



It was important for the 1st, 2nd, and 3rd stage rockets to separate at the right time. After launch, the 1st stage rocket fell off 59km above the ground and the 2nd stage rocket succeeded in breaking the fairing in an instant when the 2nd stage rocket ascended. However, a problem arose while the rocket pushed the satellite and landed in the target orbit of 700 km.



Nuriho is a project that has spent 1.9 trillion won in development alone for 12 years since the project started in 2010.



Today's failure can be a valuable foundation for the main launch in May of next year, as it overcame two failures during the Naro and finally succeeded in launching it.



In order to do that, a thorough analysis and security of the cause of the remaining period of failure must be followed.
