The Federal Aviation Administration (FAA) has mandated SpaceX and Blue Origin to conduct mishap investigations following significant issues during their recent rocket tests. SpaceX's Starship faced an explosion on its seventh test flight, attributed to over-pressurization. Meanwhile, Blue Origin's New Glenn rocket successfully reached orbit, but its booster exploded during an attempted landing. The FAA will oversee these investigations to ensure safety before future flights can resume. No injuries have been reported, but public property damage is under review for SpaceX's incident.
