Roskosmos: The cause of recent rocket crash was mixed up flight program


The cause of the crash of the Soyuz-2.1b rocket with the 19 satellites on board was an error in the programming of the launch.

As reported by Interfax referring to its sources in the space industry, the rocket was programmed for launch from the Baikonur cosmodrome, not from the Vostochny. Because of this, the upper stage performed its first maneuver for reaching the orbit in the wrong direction. As a result, instead of speeding up, it started slowing down, so the accelerating unit with the payload headed to the Earth and sank in the Atlantic Ocean.

At the moment, the government commission investigates at which stage the error occurred: at the stage of issuing the initial data or at the stage of compilation of the flight task. The fiasco with the spacecraft happened on November 28th. As the National News Service reminds, the cost of the launch was estimated at 3 billion rubles (approx. $50 million – RRT).
