May 29, 2025, Chinese private rocket firm Space Epoch (also known as SEPOCH or Beijing Jianyuan Technology Co., Ltd.) marked a significant milestone in its pursuit of reusable rocket technology with a successful flight recovery test. This critical demonstration, involving their Yuanxingzhe-1 (YXZ-1), or “Hiker-1,” verification rocket, underscores China’s accelerating efforts to develop reusable launch capabilities akin to those pioneered by SpaceX.
The test, which took place at approximately 4:40 a.m. local time from China’s first sea-based space launch center off the coast of the eastern province of Shandong, showcased the company’s mastery of Vertical Takeoff and Vertical Landing (VTVL) technology – a cornerstone of reusability.
Details of the Landmark Test
The Yuanxingzhe-1, a 26.8-meter-tall experimental rocket built from thin-walled stainless steel, ascended to an altitude of approximately 2.5 kilometers (1.6 miles). At the peak of its trajectory, its engines briefly shut down. Crucially, they then reignited as the rocket began its vertical descent, executing a controlled splashdown in the Yellow Sea. The entire flight lasted 125 seconds.
Space Epoch hailed the test as a “complete success,” stating that it performed flawlessly through every stage, from takeoff to the controlled sea landing. This achievement represents a major breakthrough in the development process of liquid reusable rockets for the Beijing-based startup.

This capability is paramount for drastically reducing launch costs and increasing launch frequency, which are critical for the economic viability of space endeavors.
- Catching Up with Global Leaders: While SpaceX has been routinely launching and recovering orbital-class rockets for nearly a decade, Chinese firms are rapidly closing the gap. Space Epoch’s successful in-flight engine reignition and controlled descent show that they are mastering key techniques required to compete on a global scale.
- Boosting Private Sector Involvement: This test highlights the increasing prominence and capability of private space companies within China. The Chinese government has been actively encouraging private investment and innovation in its booming space sector, and Space Epoch’s achievement is a testament to the progress being made.
- Paving the Way for Future Missions: The Yuanxingzhe-1, in its full operational version, is envisioned to be capable of carrying heavy satellites (over 10 tonnes) into space and returning for reuse. This would significantly contribute to China’s ambitions in various space applications, including satellite deployment, space infrastructure development, and potential future exploration.
Space Epoch’s Vision and Future Plans
Space Epoch is developing a stainless-steel, methane-liquid oxygen (methalox) type rocket, the Yuanxingzhe-1 (YXZ-1), which draws comparisons to SpaceX’s Starship in terms of material and fuel choice. The company secured substantial financing in 2023, reflecting investor confidence in its potential.
Beyond traditional satellite launches, Space Epoch has also explored innovative applications for its reusable rocket technology. In March 2024, they announced a collaboration with Taobao, an e-commerce platform under Alibaba, to explore the feasibility of using reusable rockets for parcel delivery – a concept that, while futuristic, underscores the ambitious vision for their technology.
Space Epoch, along with other prominent Chinese private space companies like LandSpace and Galactic Energy, aims for the maiden orbital flights of their respective reusable rockets later this year. This competitive landscape is driving rapid innovation within China’s commercial space sector.
Broader Context of China’s Reusable Rocket Program
China’s pursuit of reusable rocket technology is a multi-faceted effort involving both state-owned entities and private companies. The drive for reusability is seen as essential for making space access more affordable and sustainable, thereby supporting China’s ambitious long-term goals, including the expansion of its Tiangong Space Station, future lunar missions, and deep-space exploration.
While SpaceX remains the global leader in operational reusable rocket technology, the advancements made by Space Epoch and its Chinese counterparts indicate a strong commitment to becoming major players in the global reusable launch market. The recent sea-based test by Space Epoch is a clear signal that China’s private space industry is poised to make significant contributions to this evolving frontier.
How it can challenge SpaceX
This event underscores China’s accelerating ambitions in the reusable rocket sector, often drawing comparisons to SpaceX, the current global leader. While the success of Space Epoch and other burgeoning Chinese private space firms signals a growing capability within the nation’s commercial space industry, directly challenging SpaceX’s deeply entrenched dominance presents a multifaceted and formidable undertaking. The path to true competition involves not only replicating technical feats but also overcoming vast differences in operational scale, accumulated experience, and market dynamics. This essay will explore the potential avenues through which Chinese entities might vie for market share, alongside the substantial hurdles they must overcome to truly rival SpaceX’s established preeminence.
One of the most potent advantages for Chinese private space companies like Space Epoch lies in the robust backing and strategic imperative from the Chinese government. Unlike SpaceX, which thrives on private capital and commercial contracts in a largely free market, Chinese firms often operate within a framework that aligns commercial goals with national strategic interests. This can translate into significant benefits: access to state-owned infrastructure, potentially streamlined regulatory processes, and a guaranteed domestic market through state-affiliated contracts for ambitious projects such as satellite internet constellations, resupplying the Tiangong Space Station, and future lunar or Martian endeavors. Furthermore, China’s well-established and highly efficient manufacturing ecosystem could provide a crucial edge in producing rocket components at a potentially lower cost, even before factoring in the benefits of reusability. By leveraging this industrial prowess and focusing on specific market niches—such as the medium-heavy lift capabilities of Yuanxingzhe-1 designed to carry over 10 tonnes to low-Earth orbit—Chinese firms can strategically carve out a competitive space, potentially offering aggressive pricing to attract customers who prioritize cost. Moreover, Space Epoch’s choice of a stainless steel structure and liquid methane-oxygen (methalox) fuel aligns with the cutting-edge architectural decisions of SpaceX’s Starship, indicating a strategy to potentially leapfrog some legacy designs and position themselves for the next generation of fully reusable, deep-space capable vehicles.
However, the chasm between Space Epoch’s current achievements and SpaceX’s operational reality is substantial, particularly concerning technological maturity and flight heritage. SpaceX’s Falcon 9 has amassed an unparalleled record of hundreds of successful orbital launches, landings, and re-flights over nearly a decade. This vast repository of operational data and real-world experience is invaluable, enabling continuous refinement of rocket design, propulsion systems, and autonomous landing software. The recent Yuanxingzhe-1 test, while critical, was a suborbital hop, reaching an altitude of only 2.5 kilometers before a controlled splashdown. Transitioning from such a foundational test to reliable orbital-class reusability, with frequent and safe land-based or drone-ship landings, involves overcoming numerous complex engineering challenges related to thermal management during re-entry, precise guidance, navigation, and control, and robust structural integrity for repeated flights. SpaceX has painstakingly built out this expertise, perfecting its processes for rocket inspection, refurbishment, and rapid turnaround, allowing them to relaunch a Falcon 9 booster within weeks. These are sophisticated operational efficiencies that Space Epoch and its peers are only just beginning to develop.
Another significant hurdle for Chinese challengers is the sheer scale and cadence of SpaceX’s operations, particularly driven by its Starlink satellite constellation. Starlink provides a massive, continuous internal demand for launches, enabling SpaceX to achieve an incredibly high flight rate—often multiple launches per week. This high volume is crucial not only for rapidly iterating on hardware and software but also for achieving unprecedented economies of scale that further drive down launch costs. Without a comparable large-scale internal demand, Chinese private firms will find it challenging to match SpaceX’s rapid accumulation of operational experience and manufacturing throughput. Furthermore, SpaceX has invested heavily in extensive, dedicated infrastructure, including multiple launch pads, advanced landing zones, and a fleet of autonomous drone ships, as well as the integrated development, manufacturing, and launch complex known as Starbase for Starship. Establishing a similarly comprehensive and efficient infrastructure will require immense capital investment and considerable time. Finally, SpaceX’s proprietary technology and rapid innovation speed, epitomized by its Raptor engines and the iterative development of Starship, are fueled by a unique entrepreneurial culture and a willingness to embrace risk. While Chinese firms are undoubtedly innovative, the ability to consistently generate entirely new, cutting-edge technologies at a pace that rivals SpaceX’s current trajectory remains to be definitively proven.
In conclusion, while Space Epoch’s recent successful reusable rocket test represents a commendable leap forward for China’s private space sector and underscores its ambitious goals, the notion of a direct and immediate “challenge” to SpaceX’s global dominance is still a distant prospect. SpaceX benefits from a substantial head start in technological maturity, an unparalleled flight heritage, a massive operational scale driven by its Starlink network, and a highly refined, rapid reusability system. However, the consistent progress of Chinese firms, bolstered by strategic government support, a robust manufacturing base, and a focused approach to advanced propulsion and structural designs, indicates that they are rapidly becoming formidable competitors in the global launch market. The upcoming years, with planned orbital test flights of reusable rockets from companies like Space Epoch and LandSpace, will be crucial in determining the extent to which China can reshape the competitive landscape of commercial space, evolving from aspiring challengers to significant players on the world stage.
