Starship Serial Number 10 - Hop Test

Starship SN10, 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, before moving from a vertical orientation (as on ascent), to horizontal orientation, in which the broadside (+ x) 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 the descent, all three Raptor engines will ignite to transition the vehicle to a vertical orientation and perform a propulsive landing.

The flight profile is likely to follow closely the previous Starship SN8 and SN9 (hopefully with a slightly less firey landing). The exact launch time may not be known until just a few minutes before launch, and will be preceded by a local siren about 10 minutes ahead of time.
