SCRUB: Starship SN11 flight test scrubbed, but earlier static fire looked good

SpaceX is set to launch the Starship SN11 prototype to an altitude of approximately 10 kilometers. A launch attempt is possible in the afternoon local time on Friday. However, as with testing, there is always a chance that teams could decide to stand down and try again on a different day.This original content is copyrighted to NASASpaceflight (NASASpaceflight.com) and is not to be reused in any form without explicit permission.Updates: https://forum.nasaspaceflight.com/index.php?topic=53270.220Articles: https://www.nasaspaceflight.com/tag/starship/Shop: https://shop.nasaspaceflight.com/

Starship | SN10 | High-Altitude Flight Recap

Starship | SN10 | High-Altitude Flight Recap

On March 3, Starship serial number 10 (SN10) completed SpaceX’s third high-altitude flight test of a Starship prototype as it successfully ascended, transitioned propellant, and reoriented itself for reentry and an active aerodynamic controlled descent. SN10’s Raptor engines reignited to perform the vehicle’s landing flip maneuver immediately before successfully touching down on the landing pad.Test flights such as SN10’s are about improving our understanding and development of a fully reusable transportation system designed to carry both crew and cargo on long-duration interplanetary flights, and help humanity return to the Moon, and travel to Mars and beyond.
