<b>Starship SN10 Flight Test No. 1 Discussion & Updates Thread</b>

For this test, the vehicle will ascend to an altitude of approximately 12.5km (unconfirmed), 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 the it's 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 <a href="https://old.reddit.com/r/spacex/comments/k5y4if/rspacex_starship_sn8_15km_hop_official_launch/">previous Starship SN8</a> and <a href="https://old.reddit.com/r/spacex/comments/l7p7uc/starship_sn9_flight_test_no1_launch_discussion/?utm_source=reddit&utm_medium=usertext&utm_name=spacex&utm_content=t5_2srow">SN9</a> (hopefully with a slightly less firey landing).

@nextspaceflight on Twitter: Benji Reed (SpaceX): Notes that by flying Falcon 9 rockets so often, they are learning more about the launch vehicle. An anomaly during the recent Starlink mission was due to a boot having a hole in it during ascent. An engine was shutdown safely as a result.
