NASA plans to use a five-segment shuttle booster as the first stage of its Ares I rocket, one of two being designed as part of the post-shuttle Constellation program.
The two-stagerocket, called Korea Space Launch Vehicle I or KSLV-I, blasted off at 5 p.m. into blue skies from the seaside Naro Space Center, near the city of Goheung on the country's south coast.
