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.

据《曼彻斯特晚报》报道，南安普顿前锋迪布林就近期与曼联的转会传闻，以及他在南安普顿的未来发表了自己的看法。

前南安普顿主帅拉塞尔-马丁最近透露，迪布林是他见过的最有天赋的球员。据报道称，南安普顿给迪布林标价高达1亿英镑，以此吓退对这位前锋有兴趣的球队。

二 | 但由于南安普顿本赛季从英超降级，这一估值现已降至6000万英镑。

尽管价格下降，迪布林的队友们并没有忘记他最初的身价——尤其是拉姆斯代尔。

三 | 迪布林表示：“当我在训练中射门失误时，拉姆斯代尔就会喊：‘9000万！8000万！’”

谈及自己的未来时，迪布林说：“我尽量不去想这些，每天努力去训练，全力以赴。说到底，我爱南安普顿。我从八岁起就在这里。这是一个非常棒的团队，我希望与他们一起成就大事业。”

迪布林与南安普顿的合同2027年到期。

四 | 本赛季他代表球队在各项赛事出场34次，打入4粒进球以及贡献2次助攻。这位19岁的球员还吸引了切尔西、曼城、热刺以及拜仁慕尼黑和莱比锡等德国俱乐部的兴趣。如果曼联赢得欧联杯，从而获得下赛季欧冠资格，他们签下迪布林的机会将大大增加。
