Starship SN9, equipped with three sea-level Raptor engines will attempt a high-altitude hop at SpaceX's development and launch site in Boca Chica, Texas. For this test, the vehicle will ascend to an altitude of approximately 10km (confirmed), before moving from a vertical orientation (as on ascent), to horizontal orientation, in which the broadside (+ z) of the vehicle is oriented towards the ground. At this point, Starship will attempt an unpowered return to launch site (RTLS), using its aerodynamic control surfaces (ACS) to adjust its attitude and fly a course back to the landing pad. In the final stages of...
