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.

。    2026赛季美职联第19轮，迈阿密国际客场对阵纳什维尔。梅西主罚的点球被门将扑出，雷吉隆补射破门但被判罚提前进入禁区进球无效。         在父亲豪尔赫-梅西因病去世之后，梅西回国奔丧。在联盟杯小组赛第三轮，梅西重返赛场，但迈阿密国际最终负于莱昂，未能跻身淘汰赛.          对纳什维尔一战，梅西首发出场。

二 | 比赛的第21分钟，苏亚雷斯禁区内被帕拉西奥斯拉倒，主裁判判罚点球。梅西主罚点球小跳步左脚推射被门将扑出，雷吉隆补射破门，但主裁判判罚进球无效。罚丢点球之后，梅西急的不断抓自己的头发。

三 |          这次判罚让迈阿密国际球员非常不满，长时间围住主裁判争辩。

四 | 随后，视频助理裁判介入判罚，并且要求主裁判回看慢镜头。从慢镜头来看，雷吉隆提前进入禁区，回看慢镜头之后，主裁判判罚进球无效。         值得一提的是，在2026年世界杯上，梅西也两次错失点球，成为世界杯史上唯一一位单届世界杯两次错失点球的球员。
