From zero to orbital velocity: Dragon delivers to ISS
I had an eagle-eye view as the Falcon 9 rose up from its launchpad, with Dragon leading the way through the cloud covered sky. It’s sound punched through the wind, letting out a low intense rumble as it headed for orbit, getting louder and louder with each second that passed. As the rocket rose higher, its sound started to fade, until it completely disappeared. The Falcon 9 had performed its job – and it was time for Dragon to commence its part of the mission. Soon it would meet up with the ISS for the delivery of supplies and experiments to the crew.
