It looks like it took very little time to brake.
SpaceX Company showedwhat the landing of the first stage of the Falcon 9 launch vehicle looked like after the Cygnus cargo was launched into orbit. It turned out that right before landing, the rocket had to brake from supersonic speed.
In the video released by SpaceX, you can see the characteristic shock waves that occur when transitioning from supersonic speed. The rocket reached supersonic speed during re-entry into the atmosphere – no engine was used for this.
The video gives the impression that the Falcon 9 slowed down very quickly: a few seconds passed between the engine start and landing. Due to the change in the shooting angle, it is difficult to say whether the rocket really slowed down that quickly.
The rocket that launched the Cygnus cargo ship into orbit has flown into space ten times already, according to calculations Space.com, the record-breaking Falcon 9 first stage was launched into orbit 22 times, and SpaceX plans to reuse each rocket 300 times in the future.
