Zhuque-3 chief commander reveals cause of Y1 rocket's failed recovery, saying its data contributed to Y2's success_我的网站

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.

此前,吕冈茨-多尔特在一笔三方交易中被雷霆送往老鹰。

二 | ESPN记者Zach Kram近日分析了这笔交易背后的逻辑,指出多尔特在对阵马刺的系列赛中暴露出的短板,是雷霆决定送走他的关键因素。

三 |
Kram指出,在对阵马刺的系列赛中,多尔特成为球队在进攻端的薄弱环节,对手在防守时经常选择放空他的三分投射。数据显示,当多尔特在场时,雷霆的净胜分差为-63,这一数据在整个系列赛中排名垫底,且与其他球员差距明显。

通过交易多尔特,雷霆不仅获得了更多的选秀资产和薪资空间,为后续续约卡森-华莱士和米切尔提供了灵活性,同时球队在对阵马刺时的竞争力也未必会因此下降。这一操作被视为雷霆在季后赛失利后的主动调整,既优化了阵容结构,也为未来发展储备了更多资源。
