South Korea is already far behind regional rivals China and Japan in the effort to build space rockets to put satellites into orbit and has relied on other countries, including Russia, to launch them.
Launch attempts in 2009 and 2010 ended in failure.
The first stage booster of the South Korean rocket was built by Russia. South Korea has produced several satellites and has relied on other countries to put them in orbit.
South Korea wants to build a rocket on its own by 2018 and eventually send a probe to the moon.
