“It’s tumbling and we haven’t picked up any transmissions,” said Harvard astronomer Jonathan McDowell, who monitors rocket firings around the world. “Those two things are most consistent with the satellite being entirely inactive at this point.”
The United States, Asian nations and the U.N. Security Council condemned the firing of the Unha 3 rocket as a violation of council resolutions that prohibit North Korea from conducting ballistic missile operations.
“It’s clear that the rocket part of this mission worked very well for the North Koreans,” McDowell told the newspaper. “They ended up in the right orbit. But the preponderance of the evidence suggests that the satellite failed either during the ascent or shortly afterwards.”
