• FAA requires SpaceX to conduct a mishap investigation after Starship Flight 12.
• The investigation follows an off-nominal performance of the Super Heavy booster.
• Starship's Raptor engines experienced issues during the ascent phase.
• FAA will oversee the investigation and approve SpaceX's final report.

This regulatory halt may indicate the FAA's increased scrutiny of commercial spaceflight operations, which could impact SpaceX's launch cadence and Starship development timeline. The investigation suggests that the FAA is prioritizing public safety, which may lead to additional oversight measures for commercial space companies.
