SCIENCEALERT STAFF 23 APRIL 2021 Update: The crew is now successfully in orbit awaiting to dock with the space station, and Falcon 9's first stage has landed on the drone ship "Of Course I Still Love You". Original: SpaceX is attempting to launch four astronauts to the International Space Station - using a recycled Falcon 9 rocket and Crew Dragon spacecraft
It's the first time that a Falcon 9 and Crew Dragon will be reused for a crew mission, which makes it a big milestone for affordable space travel. Launch is scheduled for 09:49 UTC (05:49 ET). You can watch the historic launch attempt below. The first SpaceX launch for NASA, Crew-1, occurred in November, and the astronauts from that launch are still on board the ISS. The Falcon 9 used today is the same one that was used by Crew-1.
