SpaceX is scheduled to launch Starship SN8 tomorrow (Tuesday) sometime after 9am EST! Could be several hours after. The plan is to send 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. None of this has ever been done before.
Elon puts the chance of a successful flight and landing at 33%. This promises to be a spectacular flight one way or the other.
