North Korea extends launch window for rocket after technical problems
North Korea has extended the window for a controversial long-range rocket launch by one week after finding technical problems in an engine, state media reported Monday.
The planned launch has been widely condemned by other countries like the United States and South Korea, which say it's cover for testing ballistic missile technology. The North insists the launch is aimed at putting a scientific satellite in orbit.
When it announced its plans on December 1, the reclusive North Korean regime said it intended to carry out the launch between Monday and December 22. But on Saturday, the state-run Korean Central News Agency (KCNA) said the launch may be delayed.
In a new article Monday, KCNA reported that scientists and technicians had "found technical deficiency in the first-stage control engine module of the rocket," citing a spokesman for the Korean Committee of Space Technology.
As a result, they have decided to extend the launch period until December 29, the agency said.
