SpaceX's Falcon 9 rocket experienced a rare mishap when its first-stage booster tipped over and caught fire after landing on the droneship A Shortfall of Gravitas in the Atlantic Ocean, ending a streak of 267 successful landings since February 2021. The incident occurred following a successful mission to deliver 21 Starlink satellites to orbit, including 13 with direct-to-cell capabilities. The US Federal Aviation Administration has grounded the Falcon 9 pending an investigation into the failed landing. SpaceX has postponed a planned second Starlink launch from California to review the booster data. This failure marks Falcon 9's second recent mishap, following an upper stage malfunction in July. The setback also raises concerns about potential delays for the high-profile Polaris Dawn mission.
