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.

The Witcher 3 的开发人员曾非常专注于为玩家创造现实的环境，以至于意外地为游戏中的女性 NPC 创造了一个令人毛骨悚然又滑稽的副作用。在接受《Edge Magazine》采访时，CD Projekt Red 的任务设计师 Philipp Weber 谈到了这一策略带来的意想不到的后果，称团队过于专注于创造一个可信的世界，结果反而引起了混乱。

B | Weber 解释说，他们希望赋予 NPC 真实的行为，以增强沉浸感，并奖励玩家探索大陆的各个角落，尤其是乡村的小村庄。“因为我们专注于乡村，玩家更容易产生好奇心，”他开始说道。“如果一个村庄只有八间房子，人们会想看看这些人是否真实存在于这个世界中，还是只是虚假的摆设。现在很多人对这类细节感兴趣，这确实让我们感到困扰。

C | ”Weber 表示，当时开发团队“更专注于模拟这些 NPC 正常的昼夜循环”，而不是让他们在杰洛特在世界中游荡时做出可信的反应。他承认：“当涉及到对玩家的实际反应时，细节并没有那么多。

D | ”这意味着，尽管 NPC 有非常具体的日程安排，让他们看起来像是在日常生活中呼吸的活人，但当杰洛特闯入他们的家并挥舞武器时，他们的反应并不完全合乎逻辑。“他们会放下手头正在做的工作，东西会掉在地上，然后惊恐地逃跑，”Weber 说。不幸的是（或者说幸运的是，因为这客观上很有趣），这些“东西”包括婴儿，女性角色在逃离危险时会将婴儿扔在地上。他说：“有几个星期，女人们就在那儿四处乱扔婴儿。

E | ”虽然这个问题最终得到了解决，但在最终成品中看到它绝对会非常疯狂。Weber 进一步阐述了他们制作 NPC 的总体策略，称他们并没有给 NPC 发送具体的指令，而是让他们从某些“兴趣点”中进行选择。“村庄里的大多数 NPC，我们不会给他们设定具体的路径，”他解释道。“我们给他们提供可用的兴趣点，然后由他们自己进行寻路：‘一旦我干完伐木的活，我就会选择另一个点，也许去我家门前做木工’。例如，对于诺维格瑞港口的 50 名水手，我们制作了 200 个可能的地点，所以即使 50 个人同时活动，他们也有选择余地。”《巫师》系列的下一部作品目前正在开发中。该作以希里为中心，目前还没有正式的发布日期，但在 State of Unreal 2025 展示会上公开了早期的开发画面。我们无法想象这款游戏中的 NPC 也会乱扔婴儿，但谁知道呢。
