South Korea sent a spy satellite to space Friday, 10 days after North Korea launched one of its own.
Seoul's first indigenous spy satellite was aboard the Space X Falcon 9 rocket that was launched from the US Vandenberg Space Force Base in the state of California.
The reconnaissance satellite entered orbit approximately four minutes after launch, Seoul-based Yonhap News reported.
The launch was delayed by one day due to bad weather.
Pyongyang launched its reconnaissance satellite Nov. 21, triggering new sanctions by the US, Japan, Australia and Seoul.
After the launch, North Korea said the satellite sent pictures of various US military installations in Guam, Japan. the White House and the Pentagon.
North Korea failed twice to launch the satellite in May and August.
