China's Reusable Rocket Test: Longxing-2 Insights

China, a burgeoning power in the aerospace sector, has undertaken ambitious advancements in launch vehicle technology aimed at enhancing reusability. On January 20, 2025, a significant milestone was achieved when a Chinese state-owned enterprise conducted a high-altitude rocket test designed to evaluate reentry and landing capabilities. However, the lack of subsequent announcements regarding the results has clouded the outcome of this endeavor. This paper delves into the details of this test, its relevance in the context of China's space ambitions, the implications for future reusable launch systems, and the broader picture of the country's aerospace strategies.

The High Altitude Rocket Test

The rocket, known as Longxing-2, was launched from a makeshift site near Haiyang in Shandong province around 10:00 PM Eastern Time (0300 UTC on January 19). It is believed that this test article is a precursor to the Long March 12A reusable rocket, currently under development by the Shanghai Academy of Spaceflight Technology (SAST). The design of the Longxing-2 allows it to reach altitudes of approximately 75 kilometers, simulating the operational profile of a reusable first stage. Its trajectory involved a planned reentry burn, followed by a powered descent that would culminate in a splashdown into the Yellow Sea.

Captured amateur footage displayed the Longxing-2 ascending slowly from the launch tower, indicating a stable ascent phase devoid of noticeable irregularities. This test was intended as a follow-up to a successful vertical takeoff and landing (VTVL) demonstration conducted by SAST in June 2024, where a rocket successfully reached 12 kilometers.

Lack of Official Communications

Despite the crucial nature of the Longxing-2 test, the absence of oversight from Chinese officials regarding the outcome has sparked speculation about possible challenges encountered during the test. Over 24 hours post-launch, SAST had not released any data regarding the flight, leading to uncertainty about the success of the mission. Historically, successful tests from such enterprises in China are usually accompanied by prompt post-launch reports and analyses, making the silence surrounding Longxing-2 particularly notable.

Reusability in Space Launch Systems

Reusable launch vehicles are considered essential for reducing the costs associated with access to space. The groundwork laid by SpaceX has inspired numerous nations and corporations to invest in developing comparable systems. This movement towards reusability aims to enable the launch of payloads more efficiently and frequently. Currently, China is undertaking initiatives that emphasize not only the efficiency of its space programs but also the sustainability of its launch practices.

Related Launches and Future Prospects

China executed a total of 68 launch attempts in 2024, all utilizing expendable rockets. These included several missions by the older Long March series, which utilize toxic hypergolic propellants—a point of concern given the environmental implications. The target for 2025 is around 100 launches, executing missions that extend from scientific to commercial objectives.

The development of the Long March 12A is critical, as it promises to enhance China’s capabilities in launching megaconstellation projects—exemplified by the Guowang and Thousand Sails initiatives. Achieving regular, reusable access to space could facilitate these ambitious undertakings.

Technological Framework for Longxing-2

Implications for China's Space Foreign Policy

The ambitions outlined through these developments reflect China's broader goals in establishing itself as a leading player in the global space arena. The integration of reusable technologies into the national framework for aerospace manufacturing and operation not only aligns with cost-saving strategies but serves as a strategic tool for geopolitical maneuvering. As China seeks to enhance its influence in international space operations—particularly with its commitments in the Asia-Pacific region—it demonstrates its competitive stance on reusable technologies against other dominant players such as the United States.

“Achieving reuse in launch systems will significantly alter the landscape of space operations, presenting both opportunities and challenges that will shape future generations of commercial and state-led programs.” – Dr. Li Wei, Aerospace Analyst.

Conclusion

As China progresses its Long March 12A program, the high-altitude tests conducted with Longxing-2 play a crucial role in shaping future capabilities in reusable launch vehicle technology. The lack of communication from Chinese officials concerning the outcomes has raised questions but serves as a reminder of the challenges in adhering to operational timelines and public expectations in the domain of aerospace engineering.

Furthermore, these developments are pivotal for China's ambitions not only in enhancing its spaceflight capabilities but also for broader objectives related to its national security, economic strategies, and international collaboration in space exploration.
