SpaceX Delays Starship Flight 13 After Last‑Second Engine Start Abort

SpaceX replaced failed Raptor engines, updated startup software, ran inspections, and set a new launch window to prove the vehicle can reliably perform Starlink deployment tests.

Overview

  • An automatic shutdown stopped Starship’s final countdown when several Raptor engines did not ignite, forcing a last‑second abort before liftoff during the most recent test attempt.
  • Engineers removed and replaced the affected Raptors, changed the propulsion startup logic, and inspected the upper stage as part of prelaunch checks before setting a new target date for the next attempt.
  • Reporting differs on the next launch date, with outlets citing July 23 or July 24, and public posts by Elon Musk contributed to schedule confusion while SpaceX continues final checks.
  • The flight will carry 20 next‑generation Starlink V3 satellites on a suborbital run to test deployment and laser links; those satellites are expected to reenter and burn up rather than reach orbit.
  • The result will influence whether Starship can move from iterative test flights to operational Starlink launches, affect NASA and customer confidence, and shape investor reaction to SpaceX’s rapid test‑and‑fix development model.
