The Korea Aerospace Research Institute (KARI) has denied speculation raised by Russian media that South Korea is responsible for the failed second launch of the space rocket "Naro."

The institute denied Monday any glitches in the control system produced by South Korea, or an early separation of the first- and second-stage rockets.

The institute said the second stage of the rocket is designed to only operate after 216 seconds after liftoff, which is when the fairings that cover the satellite are separated. The agency also said the control system does not operate in the time frame before the explosion.

The South Korea-Russia joint inspection committee on the failed launch held its first meeting on Monday at the Naro Space Center in Goheung and agreed to exchange data and conduct a joint analysis.

In its second launch on Thursday, the Naro exploded midair after 137 seconds from liftoff. Two days later, the Russian media claimed the South Korea-made control system had glitches.
