NASA's astronauts Bob Behnken and Doug Hurley will be going to the ISS on SpaceX's own rocket the, Falcon 9 but they will be in the spacecraft - Crew Dragon.They will be leaving on 2 a.m. IST (Indian State Time) on May 27 making them the first people to go to Space from American soil in 9 years ! Falcon-9 is a two-stage rocket. Its lower-segment will fire for 2.5 minutes before shutting down and separating. This will leave the second stage to burn for a further six minutes to get the Crew Dragon into orbit. Once detached, the capsule will then make the rest of the journey to the ISS using its own thrusters. The second stage of the rocket will be commanded to burn up in the atmosphere. The lower-segment of the booster aims to touch down on a drone ship in the Atlantic. All the best to NASA and SpaceX for this mission !
