How Zhuque-3 Works: China Becomes First to Recover Orbital Rockets Using Two Methods

The successful landing of the first stage of LandSpace’s Zhuque-3 rocket on land marks a significant milestone in China’s pursuit of reusable launch technology. This achievement is not just about China’s space ambitions; it represents a fundamental shift in how we approach spaceflight, with far-reaching implications for satellite deployment.

Reusability has long been considered the holy grail of space engineering, and its promise is straightforward: by recovering and reusing rocket boosters, launch costs can be dramatically reduced. While companies like SpaceX have pioneered this technology, China’s progress in this area is notable because it demonstrates two different approaches to recovery. The Zhuque-3 mission used a conventional approach, deploying landing legs and bringing the booster down vertically on land. In contrast, the July recovery of the Long March-10B utilized a large net on an offshore platform.

China’s dual-track development strategy highlights its willingness to experiment with multiple technological routes to achieve its goals. While private companies like LandSpace are developing commercial launch vehicles, the state-run space programme is also pursuing reusable rocket technology. This collaboration between public and private sectors is crucial in driving innovation and reducing costs.

The implications of China’s achievement extend beyond its domestic ambitions. Reusable rockets have the potential to disrupt the global satellite market by enabling launch companies to increase their flight frequency and compete more aggressively. SpaceX’s Starlink constellation, which has already deployed over 10,000 operational satellites, is a prime example of what reusable rockets can enable.

China’s own satellite constellations, Guowang and Qianfan, are still in the early stages of deployment, with only around 200 satellites launched so far. The ability to recover and eventually reuse Zhuque-3 boosters could help Chinese launch companies catch up with SpaceX and other players in the global commercial space market.

For LandSpace, successfully landing a booster is only the first step. The recovered stage must be inspected, refurbished, and reused – a process that has already been mastered by SpaceX. China’s success in this area will depend on its ability to move from demonstration to actual reuse, and to scale up production of reusable boosters.

The Zhuque-3 mission also underscores the importance of collaboration between industry partners and government agencies. LandSpace worked closely with the China National Space Administration, which helped coordinate the launch team and supported the development of reusable rocket technology.

As China continues to pursue its space ambitions, reusability will play a critical role in determining the country’s success. The success of Zhuque-3 demonstrates that China has joined the ranks of countries pursuing this technology with serious intent. However, it remains to be seen whether China’s reusable rockets will challenge SpaceX’s dominance in the global commercial space market.

China’s progress in developing reusable launch technology is a game-changer for global spaceflight, and its implications will continue to unfold as the country scales up production of reusable boosters.
