// ORBITAL LOGISTICS AND PROPULSION TERM
Launch Sequence
The launch sequence is the precise, step-by-step series of events that occur during a rocket's countdown and liftoff, from final checks to engine ignition and ascent.
TECHNICAL DEFINITION
The launch sequence is the meticulously choreographed, time-critical series of automated and manual events, procedures, and system activations that occur during the final countdown and liftoff of a launch vehicle, culminating in engine ignition and ascent.
BACKGROUND
As of May 27, 2026, the SpaceX Starship has been launched 12 times, with 7 successes and 5 failures. SpaceX has developed Starship with the intention of lowering launch costs using economies of scale. It aims to achieve this by reusing both rocket stages, increasing payload mass to orbit, increasing launch frequency, creating a mass-manufacturing pipeline and adapting it to a wide range of space missions. Starship is the latest project in SpaceX's reusable launch system development program and plan to colonize Mars, and is one of two landing systems selected by NASA for the Artemis program's crewed Lunar missions.
