We have liftoff! At 3:52 a.m. EDT, the SpaceX Falcon 9 rocket and Crew Dragon spacecraft lit up the morning sky at Kennedy Space Center in Florida, sending Crew-4 astronauts Kjell Lindgren, Robert Hines, and Jessica Watkins, and Samantha Cristoforetti on the start of a 16 1/2-hour journey to the International Space Station.
Coming up in just one minute, the rocket will pass through Max Q – the moment of peak mechanical stress on the rocket. Following this, the Falcon 9’s first and second stages will separate.
