South Korea rocket takes off, satellite launch fails

SEOUL -- South Korea's first rocket launch Tuesday failed to push a satellite into its orbit but the flawed mission may still anger rival North Korea, coming just months the communist nation's own launch drew international condemnation.

The failure dealt a blow to Seoul's quest to become a regional space power. It comes against the complex backdrop of relations on the Korean peninsula — and recent signs that months of heightened tension over the North's nuclear program may be easing.

Also Tuesday, a South Korean newspaper reported that North Korea has invited top envoys of President Obama for the first nuclear negotiations between the two countries under his presidency, but Washington quickly said it has no plans to send the envoys to Pyongyang.

The North gave no immediate reaction to the rocket launch but has said it will watch to see if the U.S. and regional powers refer the matter to the U.N. Security Council— which in June approved sanctions on the North over its recent nuclear and missile tests.

The two-stage Naro rocket, whose first stage was designed by Russia, was South Korea's first launch of a rocket from its own territory. It lifted off Tuesday from South Korea's space center on Oenaro Island, about 290 miles (465 kilometers) south of Seoul.

The rocket was carrying a domestically built satellite aimed at observing the atmosphere and oceans. A South Korean official said they could not trace the satellite in orbit after it separated from the rocket.

"We could not locate our satellite. It seems that communications with the satellite scheduled on Wednesday are unlikely to happen," Science Ministry official Yum Ki-soo told The Associated Press late Tuesday.

He said more details could be available on Wednesday as South Korean and Russian scientists were analyzing data to try to determine the cause of the failure.

Russia's Interfax-AVN news agency, citing an unidentified Russian space industry source, said the satellite never reached orbit and problems occurred in the South Korean-built second stage of the rocket.
