What Happened to SpaceX Starship FAA Grounding?
The SpaceX Starship program has experienced multiple groundings by the Federal Aviation Administration (FAA) following test flight anomalies, most recently after the 12th integrated flight test on May 22, 2026. These groundings necessitate mishap investigations and corrective actions to ensure public safety and regulatory compliance before subsequent launches can proceed. The FAA's oversight is a critical part of Starship's development, impacting its ambitious schedule for lunar and Martian missions.
Quick Answer
SpaceX Starship launches are currently grounded by the Federal Aviation Administration (FAA) as of May 27, 2026, following a 'mishap' during its 12th test flight on May 22, 2026. The Super Heavy booster experienced multiple engine failures during its return, resulting in an uncontrolled splashdown in the Gulf of Mexico. The FAA has mandated a mishap investigation, which SpaceX must complete and have approved, including all corrective actions, before any future Starship flights are authorized. This marks another regulatory pause in the development of the crucial next-generation rocket.
📊Key Facts
📅Complete Timeline13 events
First Integrated Flight Test (IFT-1) Ends in Explosion
Starship's first full stack test flight from Starbase, Texas, ended in an explosion minutes after liftoff, failing to reach several mission objectives. This immediately triggered an FAA mishap investigation.
FAA Closes IFT-1 Mishap Investigation
The FAA closed the investigation into IFT-1, citing multiple root causes and requiring SpaceX to implement 63 corrective actions, including hardware redesigns and improved safety systems, before the next launch.
Second Integrated Flight Test (IFT-2) Sees Stage Separation, Booster Explosion
Starship IFT-2 successfully achieved stage separation for the first time, but the Super Heavy booster exploded shortly after, and the Starship upper stage was also lost later in flight. This led to another FAA mishap investigation.
Third Integrated Flight Test (IFT-3) Reaches Space, Disintegrates on Re-entry
IFT-3 progressed further than previous attempts, with Starship reaching space, but it disintegrated upon re-entry. The Super Heavy booster also experienced engine issues during its return. The FAA initiated another mishap investigation.
Fourth Integrated Flight Test (IFT-4) Achieves Controlled Splashdown for Starship
IFT-4 marked a significant success as the Starship upper stage survived re-entry and performed a controlled splashdown in the Indian Ocean. The Super Heavy booster also achieved a soft splashdown in the Gulf of Mexico, though it was not recovered.
Fifth Integrated Flight Test (IFT-5) Attempts Booster Catch
IFT-5 was the first attempt to 'catch' the Super Heavy booster with the launch tower's 'Mechazilla' arms. The booster successfully returned to the launch site and was caught, while the Starship upper stage splashed down in the Indian Ocean.
Seventh Integrated Flight Test (IFT-7) Anomaly Triggers Investigation
IFT-7, the debut of Starship V2, suffered a 'rapid unscheduled disassembly' minutes after liftoff, scattering debris and prompting another FAA mishap investigation.
Eighth Integrated Flight Test (IFT-8) Ends in Explosion
Starship IFT-8 also ended in failure, with the upper stage losing control and exploding off Florida's coast, leading to ground stops at multiple airports and another FAA investigation.
Ninth Integrated Flight Test (IFT-9) Mishap Investigation for Ship Loss
The FAA required a mishap investigation for IFT-9, focusing on the loss of the Starship vehicle which did not complete its mission as planned, although debris landed within designated areas.
FAA Releases Final EIS for Starship Operations at KSC LC-39A
The FAA announced the availability of the Final Environmental Impact Statement (EIS) and Record of Decision (ROD) for SpaceX Starship-Super Heavy operations at Launch Complex 39A at Kennedy Space Center, Florida.
FAA Releases Final Tiered EA for Increased Cadence at Starbase
The FAA announced the availability of the Final Tiered Environmental Assessment (EA) and Mitigated Finding of No Significant Impact/Record of Decision (FONSI/ROD) for increased Starship/Super Heavy launch cadence (up to 25 annually) at the Boca Chica Launch Site.
Twelfth Integrated Flight Test (IFT-12) - Starship V3 Debut
SpaceX launched the Starship V3 (Booster 19, Ship 39) on its 12th test flight. The Starship upper stage successfully deployed mock satellites and splashed down as planned, but the Super Heavy booster experienced engine failures during its return.
FAA Grounds Starship Following IFT-12 Mishap
The FAA declared the IFT-12 a 'mishap' due to the Super Heavy booster's engine failures and hard splashdown. All Starship launches are halted, and SpaceX is required to conduct a mishap investigation and implement corrective actions before resuming flights.
🔍Deep Dive Analysis
The SpaceX Starship program, designed to revolutionize space travel with its fully reusable mega-rocket, has frequently encountered regulatory pauses from the Federal Aviation Administration (FAA) due to anomalies during its ambitious test flight campaign. These groundings are a standard part of the FAA's oversight for commercial spaceflight, ensuring public safety and adherence to federal regulations. Each significant deviation from a planned flight profile, termed a 'mishap,' triggers an investigation that must be led by SpaceX and approved by the FAA before flights can resume.
The initial integrated flight test (IFT-1) in April 2023 ended in an explosion shortly after liftoff, leading to a lengthy FAA investigation that identified 63 corrective actions. Subsequent flights in late 2023 and throughout 2024 and early 2025 also faced scrutiny, with several ending in uncontrolled events or 'rapid unscheduled disassembly,' prompting further mishap investigations. These incidents, while part of an aggressive test-and-learn development approach, have highlighted the complex interplay between rapid innovation and stringent regulatory requirements. Environmental reviews, including Programmatic Environmental Assessments (PEAs) and Environmental Impact Statements (EIS), have also been ongoing, with the FAA authorizing increased launch cadences at Starbase in Boca Chica, Texas, and Kennedy Space Center, Florida, by early 2026.
A key turning point came with the debut of the Starship V3 on its 12th integrated flight test on May 22, 2026. While the Starship upper stage successfully completed its mission profile, including deploying mock Starlink satellites and performing a controlled splashdown in the Indian Ocean, the Super Heavy booster experienced critical engine failures during its descent. Instead of a controlled landing in the Gulf of Mexico, the booster made a hard splashdown, which the FAA immediately classified as a mishap.
As of May 28, 2026, all SpaceX Starship launches are on hold pending the FAA-mandated mishap investigation into the May 22nd flight. This grounding disrupts SpaceX's ambitious plans to increase its launch cadence, deploy Starlink V3 satellites, and support NASA's Artemis program for lunar landings, which heavily relies on Starship. The duration of this grounding is uncertain, as past investigations have taken months, but SpaceX is known for its rapid iteration. The FAA's approval of SpaceX's final report and proposed corrective actions is paramount for Starship's return to flight.
