A technical glitch forced South Korea to abort liftoff of its first rocket into space, delaying a launch that threatened to stoke tensions with North Korea even as Pyongyang joined in mourning a leader who pushed tirelessly for reconciliation.
The rival Koreas are eager to develop space programs, and had aimed to send satellites into space this year. In April, the North launched a three-stage rocket it claimed sent a communications satellite into orbit; some experts doubt the mission succeeded.
Washington, Tokyo and others called that launch a disguised test of long-range missile technology. The UN Security Council condemned the launch, saying it was a violation of resolutions banning North Korea from ballistic missile-related activity.
