On the afternoon of August 30, 2025, LandSpace convened a review meeting for the flight failure closure of the ZQ-2 Improved (Y3) launch vehicle. After deliberation, it was unanimously agreed that the failure could be formally closed.
The ZQ-2 Improved (Y3) launch vehicle ignited and lifted off at 09:17 on August 15, 2025, from the Dongfeng Commercial Aerospace Innovation Test Zone. The first-stage flight proceeded normally, followed by a successful stage separation. The second-stage ignition, along with all associated systems, operated normally, and the fairing separation was also successful.
However, at 258 seconds after liftoff, an abnormal voltage drop occurred in the second-stage servo power supply bus, leading to loss of attitude stability. The autonomous safety control system onboard initiated self-destruct procedures, resulting in the failure of the flight test mission.
Through analysis of flight telemetry data, simulation calculations, and fault investigation tests, the cause of the failure was identified as an arc discharge short circuit in the high-power 450V DC power supply bus of the second-stage actuator drive circuit. This occurred under low-pressure conditions during the second-stage flight, leading to a failure in the control actuators and subsequent mission loss.
LandSpace will deeply absorb the lessons from this flight failure and take this opportunity to implement a series of additional control measures. These will strengthen risk management processes, enhance quality control during the development and production of outsourced and cooperative products, and further improve the launch and flight reliability of the company’s mission models. We are committed to ensuring the success of subsequent missions.
