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 joint ventures (JVs) of General Motors (GM) will continue to build Chevrolet products in China and explore opportunities in non-US overseas markets, General Motors China confirmed to the Global Times on Monday, in response to media reports claiming that the US brand is ending new car sales in China and retreating from the Chinese market.
"We believe that Cadillac and Buick are well positioned to compete in the segments we are targeting in China to support sustainable growth, while our JVs' Chevrolet portfolio is best positioned for our export markets," GM China said.
"We continue to stand by our existing 7 million-plus Chevrolet customers in China with aftersales support," it said.
Zhang Xiang, secretary-general of the International Intelligent Vehicle Engineering Association, told the Global Times on Monday that Chevrolet's business adjustment in China may be out of a combination of factors​ including the rapid development of new energy vehicles (NEVs) in the market and the complete auto industrial chains that empower auto production.
"Chevrolet has long been anchored in fuel-powered vehicles. As China's NEV penetration rate deepens, the domestic fuel-car segment keeps shrinking. On the other side, many US automakers have fallen well behind their Chinese rivals on electrification and smart-driving technology. Against this backdrop, some foreign carmakers are proactively reshaping their China strategies," Zhang said.
China's automotive supply chain is exceptionally complete, with cost advantages in aspects including raw materials, parts sourcing, and labor. For a company like GM, using its Chinese operations as an export base is therefore a very natural choice, Zhang said.
The Chevrolet brand, in particular, has already executed a strategic pivot toward export business. Data from the China Passenger Car Association shows that Chevrolet's exports reached 17,159 units in 2024 and 15,917 units in 2025 - both figures surpassing its retail sales in China, China National Radio reported.
Many global automakers are forging deeper and longer-term ties with China, as the country's role evolves beyond a key market into an increasingly important hub for automotive research and development and innovation.
Recently, SAIC Motor and GM signed an agreement to extend their JV partnership by 20 years to 2047. A month earlier, Honda Motor and GAC Group signed a strategic agreement to renew their JV partnership in GAC Honda, extending their cooperation to 2038 while keeping the existing equity structure unchanged.
