South Koreans, Russians Remain at Odds Over Naro-1 Launch Failure

South Korean and Russian engineers remain at odds over what caused the Naro-1 rocket to fail just 137 seconds after liftoff on June 10, 2010, according to an Oct. 20 report from the Yonhap news agency. The booster, which includes a Russian first stage and South Korean second stage, lifted off safely from the Naro Space Center but failed in flight.

South Korea and Russia failed to agree on the cause of last year’s aborted launch of a jointly built space rocket, only offering recommendations that will help prevent all possible causes cited by both sides, the South Korean government said Thursday.

An earlier Naro-1 launch failed in August 2009. Both stages worked well, but the fairing protecting the South Korean satellite failed to separate. The satellite and fairing fell into the ocean. A third test launch is tentatively planned for next year.
