Now put on year space suit and fasten your seat belt. You are going to start the most dangerous part of your trip: the launch. The countdown begins: '10,9,8,...3,2,1. Lift-off!'. The 300 tonnes of the rocket leave the ground. You're on your way! Two minutes after lift-off the booster rockets fall away. The main body falls away when it runs out of fuel and the smaller rocket takes over. It takes Soyuz into orbit, then it falls into the atmosphere, where it burns.
