Starship’s 14th Test Flight: Engine Failure Raises Stakes for NASA’s Artemis Moon Plans
By Drooid · · How we work
Core Event – Engine Shutdown During Orbital Test
On September 28 2026 SpaceX launched the 14th integrated test of its Starship vehicle from Starbase in Texas. After a successful boost from the Super Heavy first stage, the upper-stage “Ship” suffered an unexpected shutdown of one of its Raptor engines shortly after stage separation. The anomaly forced mission control to curtail the flight, ending the orbital segment after roughly three hours instead of the planned ten-hour, six-orbit profile. Despite the early termination, Starship deployed a commercial payload of 26 next-generation Starlink V3 satellites and performed a controlled deorbit and splashdown in the Pacific Ocean.
Background & Context – Starship’s Role in Artemis
Starship is one of two vehicles selected by NASA to serve as a Human Landing System for the Artemis program, which aims to return astronauts to the lunar surface by 2028. The agency will fly whichever lander is ready first, putting SpaceX’s Starship in direct competition with Blue Origin’s Blue Moon. Artemis III, slated as a low-Earth-orbit rehearsal in the summer of 2027, will test rendezvous and docking maneuvers, while Artemis IV is planned as the first crewed lunar landing. Successful in-orbit performance of Starship’s Raptor engine cluster is essential because the same propulsion system will be used for lunar ascent and descent.
Data & Statistics – Flight Metrics and Payload
- Flight number: 14 (first full orbital attempt)
- Super Heavy booster: 33 Raptor 3 engines (two reported failures during ascent)
- Upper stage: six Raptor engines (one shut down during ascent)
- Payload: 26 operational Starlink V3 satellites, each adding roughly a terabit per second of capacity
- Achieved altitude: about 275 km (? 171 mi)
- Mission duration: ~3 hours (planned 10 hours)
- Planned orbits: six (actual orbits completed not disclosed)
Official Statements & Responses
NASA Administrator Jared Isaacman posted on X that the flight was “gorgeous” and praised the successful orbital insertion and satellite deployment, while noting that the agency will continue to monitor the engine anomaly closely.
SpaceX emphasized that the vehicle still met its primary objectives of reaching orbit and delivering its payload.
Conflicting Reports & Gaps
Sources differ on the exact configuration of the upper-stage engine cluster. Reuters and several outlets describe three sea-level Raptor engines plus three vacuum-rated engines, whereas other reports cite a total of six Raptor engines on the upper stage. Mission duration is consistently reported as three hours, but the planned ten-hour timeline varies between “nearly ten hours” and “almost ten hours.” The number of completed Earth orbits remains unspecified; some accounts mention two orbits before deorbit, while others simply note that the six-orbit goal was not achieved. No source has identified the root cause of the engine shutdown.

What’s Next – Upcoming Tests and NASA Milestones
SpaceX is preparing Flight 15, which could attempt the first “tower catch” of the upper stage; planning documents list a launch window later this month. NASA’s Artemis III rehearsal in low Earth orbit is targeted for summer 2027, and the agency’s inspector-general has estimated that more than ten Starship tanker flights will be required to refuel a lunar-bound HLS in Earth orbit. Artemis IV, the first crewed lunar landing, remains scheduled for 2028. Resolving the engine issue and demonstrating rapid reusability will be critical to keeping these milestones on track.
