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.

二 | 北京时间1月11日，美国当地时间星期五，航天X将在2019年执行第一次火箭发射任务。发射窗口从东部时间星期五上午10:31开始（北京时间星期五晚上23:31）。

三 | 上周五发射的Falcon-9一等火箭在去年9月的铱计划中使用了75颗通信卫星。

四 | 这将是航天X公司第八次也是最后一次发射卫星。

五 | 在这次任务中，SpaceX将把10颗铱新一代卫星送入极地轨道。猎鹰9号一级火箭于去年9月发射，当时发射任务是将一颗18号卫星送入地球同步转移轨道。第一级火箭将在发射过程中从刚刚阅读的指示船上取回。总而言之，对于SpaceX来说，这是一个标准的发射任务。毕竟，“猎鹰9号”火箭已经发射了7次铱新一代卫星，第一级火箭也在实践中进行了测试。在2017年和2018年，航天C分别完成了18次和21次火箭发射。预计2019年将完成16-20猎鹰9号火箭发射和2-3猎鹰重型火箭发射。
