Photo: courtesy of LandSpaceThe cause of an unsatisfying recovery of the Zhuque-3 Y1 carrier rocket has recently been revealed by Zhuque-3's chief commander, who said an abnormal combustion occurred during a landing ignition as the rocket descended toward the ground, state broadcaster China Central Television (CCTV) News reported on Wednesday.
The recovery of the first stage of Zhuque-3, China's first reusable carrier rocket developed by LandSpace, was failed during a test flight back on December 3, 2025, while the second stage of the rocket managed to successfully enter the designated orbit, according to the Xinhua News Agency.
Dai Zheng, chief commander of Zhuque-3, said that when the rocket was about 3.3 kilometers above the ground, it needs to perform a rapid deceleration maneuver by reigniting its engine, a process known as a "landing ignition."
"The ignition sequence was completed and the engine did ignite, but abnormal combustion occurred afterward. The rocket eventually crashed near the edge of the landing pad," Dai said, according to CCTV.
Although the rocket did not achieve a successful recovery, the mission, China's first orbital-class rocket first-stage recovery test, collected telemetry data during the return phase, provided a clearer picture of the flight environment throughout the recovery process, and yielded a large amount of valuable first-hand test data, per CCTV. 
Drawing on the data collected from the Zhuque-3 Y1 mission, the development team made improvements to the Y2 launch vehicle.
Eight months after the Y1's unsatisfying recovery, the Zhuque-3 Y2 reusable launch vehicle on Wednesday conducted a flight test, carrying not only a satellite payload but also successfully carried out a major test of China's emerging reusable rocket capabilities. After completing its orbital mission, the rocket's first stage attempted a controlled return and recovery.
The Y2 mission was conducted on the basis of experience accumulated from the previous flight test, with improvements focused on recovery reliability, flight control and engine performance.
LandSpace said it optimized the first-stage landing propulsion scheme by reducing the number of engines used during landing ignition, simplifying system design and improving reliability during the recovery phase. The company also added an autonomous safety control function capable of predicting landing points based on flight conditions and making corresponding safety adjustments.

。巴尔科随即转身推搡贝林厄姆,多名球员迅速围拢。阿根廷后卫奥塔门迪上前与贝林厄姆发生争执,随后英格兰队友将贝林厄姆拉开。英格兰球员摩根·罗杰斯也与阿根廷球员发生口角,一度需要队友阻拦。本场比赛对抗激烈,两队在上半场就出现19次犯规。英格兰队第55分钟由戈登打破僵局,但阿根廷队凭借恩佐·费尔南德斯和劳塔罗·马丁内斯在比赛尾声阶段的进球完成逆转。贝林厄姆的赛后行为是否会受到国际足联追加处罚,目前尚待确认。英格兰队将在18日与法国队进行三、四名决赛;阿根廷队将在19日的决赛中对阵西班牙队。(完)
