  • Korea South South Korea became familiar with large-scale rocketry through maintenance and modification activities on American-supplied Honest John and Nike Hercules tactical missiles. By the 1990's Korea had developed an independent capability to manufacture solid propellant rocket motors of up to one tonne mass. In 1990 KARI was funded to build the first indigenous sounding rockets, flown as the KSR-I and KSR-II. In December 1997 KARI was allowed to proceed with development of liquid oxygen/kerosene rocket motor for an orbital launcher, but this was abandoned when the South Korean government decided it wanted to be among the top ten spacefaring nations by 2015. The existing program was too limited in growth potential to allow that. Therefore it was decided to leapfrog the technology by contracting with Russian companies. First launch of the KSLV-I launch vehicle from the new space centre took place in 2010. More...
