广州日报讯（全媒体记者张喆）2022年第九届女足东亚杯今天上演最后一轮角逐，北京时间今天18时20分，东道主日本女足将与中国女足在鹿岛体育场上演冠军争夺战。过去7届女足东亚杯，日本女足先后4次夺冠，而中国女足最好的成绩仅是亚军。中日女足在东亚杯上7次交手，中国女足除了2003年曾逼平对手一次，其余6届遭遇六连败。

二 | 不过，在今年2月的亚洲杯半决赛上，中国女足面对日本女足上演了神奇翻盘的一幕。对于那场失利，日本女足希望在本届东亚杯上得到弥补。过去两轮，日本女足先后以2比1击败韩国女足，以4比1轻取中国台北女足，目前积6分、有4个净胜球暂居榜首。中国女足积4分、2个净胜球排次席。

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.
