A Huge Embarassment for North Korea

The North Korean attempt to launch their satellite named “Kwangmyongsong-3” aboard their three stage rocket “Unha-3” has ended in failure just prior to, or during the separation of the first and seconds stage.

The timeline for the flight follows:

  • 22:38:55 UTC on 12 April 2012: the rocket lifted off
  • 22:39:49: Sejong the Great has detected the rocket on its radar
  • 22:41:10: The radar blip splits into two (A and B); presumably an explosion happened.
  • Altitude: 70.5 km, Speed: Mach 5.6
  • 22:42:55: the rocket passes over the South Korean island of Baengnyeong. Altitude: 151.4 km, Speed: Mach 4.4
  • 22:47:42: Object A broke up into pieces and disappeared from the radar
  • 22:48:02: Object B broke up into 3 pieces at an altitude of 11 km and at mach 1.7. The nominal splashdown point is 190-200 km west of Kunsan.

Speculation is they will attempt to set off nuclear explosion to salve the public relations wounds, but experts suspect they no longer have enough plutonium for that to happen.
