Digest  KSLV-1 (Naro-ho)

* The Korea Space Launch Vehicle-1 (KSLV-1) blasted off from the Naro Space Center successful. The first stage engine and second stage solid
    rocket motor fired normally. However one of the two fairings covering the satellite did not fall off properly. The fairings weighed four times
    more than the satellite, making it impossible for the second stage rocket to generate the necessary thrust to keep the satellite in the right orbit.
    The speed of the motor and satellite had fallen to 6.2 km per second. The satellite was likely to fall back towards the earth and to be destroyed
    in the atmosphere.

**At 137 seconds into the flight, mission control lost contact with the rocket as it would have reached the altitude of 70 km.
     Looking from the bright flash seen on the camera mounted on the tip of the rocket, it appears the Naro exploded in flight during the first-stage sequence.
     An anonymous source from the Russian aerospace industry told Russia's state-run media, RIA Novosti news agency that a flash caught on camera
     during the communication cut-off could have been associated with a premature separation of the first-stage and second-stage rockets, leading to the failure.
     Korean specialists also say that the incident might have been caused by a fault in the pyrotechnical system of the separation between two rockets.
