A committee investigating the failure by Naro, the nation’s first space rocket, to put a satellite into orbit has zeroed in on the possible cause of the failure.

The committee said Monday that a wiring malfunction or a jamming of machinery is likely to have caused the delayed separation of a fairing covering the satellite. The delay is thought to be the reason the Naro failed to put a satellite into orbit last August.

The committee said it is difficult to determine the exact cause of the failure as the committee conducted its investigation based solely on telemetric data and above-ground testing.
