NEW LOOK: North Korea's launch pad

A new satellite image of the launch pad expected to be used by North Korea next month shows no sign yet of any launch activity.

Satellite imagery company GeoEye provided CNN a new image of the site from where North Korea's controversial rocket launch will take place.

The image of the Tongch'ang-dong facility was taken on March 20 by GeoEye. It shows no missile or launch vehicle visible, according to an analysis by GlobalSecurity.org's Tim Brown.

"Since we are about three weeks away, and based on previous DPRK (Democratic People's Republic of Korea) missile launch preparations, I would not expect to see any noticeable activity at the site until about one week prior to the launch," Brown told Security Clearance.

The imagery obtained from GeoEye, taken on March 20, shows a completed launch pad, and the extension of a 15-mile rail spur that ends at the missile checkout building.
