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.

    　　拉斯维加斯王牌队近期状态出现明显波动，过去10场比赛取得5胜5负。球队上一场客场以71-111惨败给纽约自由人，防守端被对手完全打穿。更致命的是，球队正面临严重的伤病危机——绝对核心阿贾·威尔逊因伤确认缺席本场比赛。本赛季威尔逊场均贡献26.3分、9.7个篮板和2.0次盖帽，是球队攻防体系的绝对支柱。她的缺阵直接导致王牌失去内线核心得分点和护框屏障，球队整体实力将大打折扣。此外，前锋基尔斯坦·贝尔、中锋仙扬·帕克等多名轮换球员也因伤无法出场，主力框架严重受损。王牌虽然是主场作战（本赛季主场9胜5负），但如此残阵面对状态火热的对手，统治力已大幅削弱。
    　　华盛顿神秘人队则呈现出截然相反的态势，球队目前正处于一波七连胜的强势轨道中，近10场取得8胜2负的出色战绩。神秘人的整体排名已升至联盟第6位，客场战绩为8胜6负，具备客场抢分能力。

二 | 球队阵容极为完整，目前没有主要球员出现在伤病名单中。

三 | 核心西特龙本赛季场均贡献17.1分，是球队最稳定的外线得分点，在威尔逊缺阵的情况下，她将拥有更大的进攻空间。两队本赛季此前交手一次，神秘人在主场以100-99险胜王牌，比赛最后5分钟神秘人一度落后9分，却依靠连续防守和关键进攻完成逆转，展现了极强的韧性。

　　这是一场“残阵卫冕冠军”与“状态火热新贵”之间的对决。王牌的统治力建立在威尔逊的内线统治之上，一旦她缺阵，球队的进攻效率和防守体系都将出现明显下滑。上一场71-111的惨败已经证明，缺少核心的王牌难以维持高强度攻防。
