The failed launch of a South Korean rocket in Brazil last December was caused by a gas leak, according to its developer Innospace Co., which is gearing up for another attempt in the third quarter of this year.

The Hanbit-Nano, developed by the South Korean rocket company, crashed less than a minute after liftoff from the Alcântara Launch Center on Brazil’s Atlantic coast.
