from Russia in preparation for the launch. A new preliminary launch date no earlier than November 24, 2012 was also announced. While no cause for the failure of the second launch has officially been declared, changes to the third launch were to include eliminating the flight termination system on the second stage (built by Republic of Korea KARI), and changes to the system on the first stage (supplied by Russia). Changes to the electrical system that operates the payload fairing were also to be made. The first stage of the rocket Naro-1 for the third attempt was delivered from the Russian manufacturer at the end of August 2012. Shortly after the mishap with the second launch attempt, South Korea had announced the third flight would take place in 2011. Specific plans were never announced and no launch attempt was made in 2011. Political impact The third launch of Naro-1 occurred one month after North Korea's successful December 2012 launch of their Unha-3 rocket developed with North Korean technology. The launch came in the wake of news that North Korea had plans for a third nuclear test.
