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.

原标题：台积电 2nm 预计 2025 年量产，业界看好其领先三星和英特尔9 月 12 日消息，据台媒《经济日报》报道，晶圆代工厂台积电 2nm 制程将于 2025 年量产，市场看好进度可望领先对手三星及英特尔。

二 | 台积电先进制程进展顺利，3nm 将在今年下半年量产，升级版 3nm（N3E）制程将于 3nm 量产一年后量产，即 2023 年量产，2nm 预计于 2025 年量产。

三 | 台积电 2nm 厂将落地竹科宝山二期扩建计划，“竹科管理局”已展开公共设施建设，台积电 2nm 厂也开始进行整地作业。台积电 2nm 首次采用纳米片架构，相较 N3E 制程，在相同功耗下频率可提升 10% 至 15%。

四 | 在相同频率下，功耗降低 25% 至 30%。台积电总裁魏哲家日前在技术论坛中强调，台积电 2nm 将会是密度最优、效能最好的技术。市场也看好，台积电 2nm 进度将领先对手三星及英特尔。IT之家了解到，此前消息称，虽然在 3nm 世代略有保守，但无论如何，鳍片 (Fin) 宽度都已经接近实际极限，再向下就会遇到瓶颈，所以外资法人预估台积电 2nm 先进制程将采用环绕式闸极场效电晶体 GAAFET 高端架构生产 2nm 芯片。返回搜狐，查看更多责任编辑：
