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.

。    Tokyo, Oct 22 (UNI) Japan will send troops for a joint training in northern Australia as part of a bilateral agreement on enhancing defense activities in each other's territories, the prime ministers of both countries said in a joint statement after a meeting on Saturday.
Australian Prime Minister Anthony Albanese and Japanese Prime Minister Fumio Kishida met in the Australian city of Perth and reaffirmed the Special Strategic Partnership status of bilateral relations, according to the joint statement released by the Australian government.
"They decided to continue to identify ways to enhance interoperability, including through expanding existing military exercises and training. They instructed ministers to build on the Reciprocal Access Agreement as early as possible once it enters into force, including enhancing defence activities in each other’s territories. They welcomed the announcement that Japan Self-Defense Forces will train and exercise in northern Australia to increase interoperability with the Australian Defence Force," the statement read.
Australia and Japan remain committed to deepening bilateral defense collaboration in space, cyberspace, information sharing and regional capacity-building toward a "free and open Indo-Pacific region that is inclusive and resilient," the two leaders said.
Albanese supported Kishida's determination to reinforce Japan's defense capabilities within the next five years by increasing its defense budget.
They signed a update to the 2007 Joint Declaration on Security Cooperation, which will determine the development of bilateral defense and security relations for the next 10 years.
Kishida's visit to Australia will last until Sunday. Albanese has already visited Japan twice: the first time - immediately after his election in May this year to participate in the Quad summit, and the second time when he went to the funeral of former Japanese Prime Minister Shinzo Abe on September 27. Kishida had his Australian visit planned for January of this year but had to reschedule due to the COVID-19 situation in Australia.
