North Korea has extended the launch window for its Unha rocket, a day after saying they were looking to “readjust the launch timing.”

The rocket was originally scheduled to launch sometime in a two week window from December 10 and 22nd. The DPRK’s Korean Committee for Space Technology now say the launch window will run an extra week until December 29.

The news was announced in a statement carried by KCNA:

As already reported, scientists and technicians of the DPRK are pushing forward the preparations for the launch of the second version of Kwangmyongsong-3, a scientific and technological satellite, at a final phase.

They, however, found technical deficiency in the first-stage control engine module of the rocket carrying the satellite and decided to extend the satellite launch period up to Dec. 29. – KCNA, December 10, 2012.

Some recent satellite images of the Sohae Launch Facility have shown snow fall, which could also account for the change.
