Russia has expressed regret over South Korea's first space rocket launch on Tuesday, as the rocket overshot its intended target and failed to place a satellite into orbit.

The Russian Federal Space Agency and the Khrunichev State Research and Production Space Center, a producer of space-launch systems, posted retractions on their Web sites after initial signs showed that a satellite carried by the “Naro” rocket had successfully entered into orbit.

The Russian Federal Space Agency later posted on its Web site that the launch was a success for Russia and a partial success for South Korea, citing that the agency and the state-controlled Khrunichev company, which made the rocket’s first-stage engine, believe the first stage of the two-stage Naro rocket operated as planned.

A spokesman for the Russian space agency said the cause of the satellite’s failure to reach its intended target has yet to be determined.
