SpaceX is has a scheduled launch window for Starship SN9 sometime this afternoon from now until 7pm EST. This follows last year's successful launch and "difficult" landing of Starship SN8.
People are guessing the launch will be towards the later part of the afternoon.
The plan is to repeat the SN8 flight profile by sending the rocket on a flight to a 12.5 km (41,000 ft) height. At this point, the rocket will do a belly flop and "skydive" with it's fins to the landing pad. As it gets closer to the ground, it will reignite it's engines and rotate to a vertical position and use retro-propulsion to land vertically.
