Notes:

• The recent Soyuz-FG carrier rocket failure was caused by a malfunctioning sensor damaged during the rocket′s assembly at the Baikonur Cosmodrome, the Russian space agency commission said, adding that it was not a design error.
• It was a collision of elements during the separation of the carrier rocket′s first and second stages that led to the abortive launch of the Soyuz MS-10 rocket carrying Russian commander Aleksey Ovchinin and NASA astronaut Nick Hague to the International Space Station on October 11. The collision itself was provoked by a deformation of the detector that signals separation of the stages, the commission established by the Russian space agency Roscosmos has found.
• The video, released on Thursday, confirms that the dramatic mid-air failure was caused by a malfunction in the detector that signals separation of the rocket′s first and second stages.
• The footage first shows the vehicle’s regular flight. However, about 2 minutes after takeoff, the rocket spins out of control. This exact moment is seen in the video.
