North Korea set a major record over the weekend following the launch of their first satellite -carrying rocket. The problem, however, is that the Kwangmyŏngsŏng-4 satellite doesn't even work at all. And it's tumbling about in orbit, on a trajectory to burn-up in orbit. And smash into the Earth.
The US Department of Defense and other agencies around the world have analyzed the orbital object and have determined that it's in an unstable orbit, and absolutely incapable of functioning in any useful way. Other than as a proof of concept.
Of course officials from various countries and the U.N. Security Council are worried that this test is a display of their technological prowess and a secretive way to test technologies that could evolve into better intercontinental ballistic missiles, or even spy satellites.
South Korea has managed to analyze wreckage from previous failed launches and determined that they used very old technology that was highly unreliable. Around 270 pieces of debris from this current launch are currently being analyzed by the South Korean Defense Ministry.
