Rocket manufacturer iSpace said on 1 March on its WeChat account that it has completed investigation of its launch failure, vowing that the firm will ramp up efforts on management and technology improvement. "Following 28 days of investigation and analysis, we have completed problem location analysis, fault simulation and recurrence, test verification and assessment and improvement measures." The flight failure of the SQX-1 Y2 rocket was located within a piece of insulation foam that had fallen off and fell on the IV grid rudder, causing the rudder to be blocked under aerodynamic pressure, and the foam was blown off again from the rudder later during the flight. After the rudder resumed the control system to track the command, the rudder deflection angle completed a deflection of more than 30 degrees in a short time, which caused a sudden change in the attitude of the rocket body, which led to the failure of the flight, according to the firm's analysis.
