North Korea's next launch

DigitalGlobe, a satellite imaging firm, has released a photo of what appears to be the next North Korean rocket:

The Register says:

The image, released by commercial satellite Earth-imaging firm DigitalGlobe, shows the North Korean launch gantry at Musudan-ri, where the country's larger missiles and rockets are test fired. In commercial satellite images produced in recent months, the gantry has stood empty: but in the DigitalGlobe image — taken yesterday — a large multistage rocket is clearly visible.

Both the US and Japan have deployed warships equipped with SM-3 ballistic missile interceptors to the area. However, Secretary of State Hillary Clinton has said there are no plans to interfere with a North Korean launch; this suggests that the warships will only shoot if the rocket's trajectory appears to offer a threat to Japan. North Korea has previously test-fired a shorter ranged missile across Japan into the Pacific.
