SPACE.com: Yesterday’s launch of South Korea’s Naro-1 rocket failed when the rocket’s second-stage solid-fuel booster exploded 137 seconds after liftoff. Based on the Russian Angara rocket, Naro-1 is designed to carry South Korean payloads into space. The launch attempt was the second for a Naro-1. The first attempt, which took place last August, also ended in failure.
