This is the launch video of the Dragon COTS 2 Demo 2 mission the first mission of Dragon to ISS and the ever first mission of a private organization to ISS.
You can see one of the great moments in this launch, the deployment of Dragon’s solar arrays on T + 12 minutes, which is on about 58 minutes in the video. This action makes Dragon a fully functional space craft and makes all the SpaceX people cheer!
