North Korea expands launch window for rocket after technical problems.

North Korea has extended the date for the controversial long-range rocket launch by 1 week after finding technical problems in the engine, state media noted Monday.

The planned launch which is now widely condemned by other countries like the usa and South Korea, which they say that is cover regarding testing ballistic missile technological innovation. The North insists the launch is targeted at putting a scientific satellite in the orbit.

When the plan was announced on December 1, North Korean regime said it intended to handle the launch between December 10 and 22. But on Saturday, the state-run Korean Main News Agency (KCNA) said the launch will be delayed.

In a completely new article Monday, KCNA reported that professionals and technicians had "found technical deficiency from the first-stage control engine module on the rocket, " citing a spokesman for that KCST[Korean Committee of Space Technology].
