[ABORT] SpaceX Starship Flight 13- Launch & Landing - LAUNCH STREAM

SpaceX aborted the Starship Flight 13 launch attempt at the moment of ignition after automated systems detected that four Raptor engines failed to start. The vehicle remains safe on the pad, and the team has begun detanking the propellants to prepare for repairs and a future attempt.

• Automatic abort — The launch sequence was halted at ignition (T-0) when automated safety checks identified that a subset of engines did not light [2:52:35].

• Engine failure — Telemetry revealed that four engines in the inner ring failed to achieve ignition during the startup sequence [2:53:43].

• Safety systems — Automated protocols functioned as intended, safely shutting down the engines and preventing damage to the launch site despite the water deluge system activating [2:53:09].

• Next attempt — Elon Musk confirmed plans to remove and replace two Raptor engines, with the next launch opportunity targeted for early the following week [2:55:15].

• Recovery operations — Crews initiated detanking procedures to return propellants to storage tanks and prepare for vehicle maintenance [2:53:05].

• Rollback plans — The booster will return to the production site for engine replacement, requiring the transport stands to be moved back to the launch pad to facilitate these operations [2:55:43].

• What is the standard procedure for removing and replacing Raptor engines on the Super Heavy booster?

• How does the automated shutdown process function when an engine failure is detected during ignition?
