Unastella, a South Korean rocket startup, has successfully raised $24 million in a Series B funding round, bringing its total funding to $44 million. This investment comes as the global space launch market heats up, with various Asian startups vying for a share of a sector traditionally dominated by the U.S. and China.
Founded four years ago, Unastella launched its own rocket, the Una Express-I, from South Korean territory in May 2025. The company is focused on developing its own launch vehicles and engines, primarily targeting small satellite launch services.
Technology and Innovation
Unastella employs a kerosene and liquid oxygen propulsion system, a reliable combination in rocket technology, similar to that used by SpaceX's Falcon rockets. However, the startup has opted for an electric motor pump instead of a traditional turbo pump, which simplifies the design and reduces costs. While this choice results in a heavier system, limiting payload capacity, CEO Jae Park emphasizes the company's focus on rapid market entry over sheer performance.
In-House Operations
The company manages all aspects of its operations internally, including design, manufacturing, and flight data analysis. The launch of UNA EXPRESS-I served as a comprehensive test of its end-to-end system.
Leadership and Experience
Jae Park, the founder and CEO, has extensive experience in rocket engine development. Prior to establishing Unastella, he worked on combustion systems for Korea's Nuri rocket and contributed to European launch vehicle engines at the German Aerospace Center.
Future Prospects
Although Unastella is not yet generating revenue, the recent funding indicates strong investor confidence in its roadmap. The upcoming UNA EXPRESS-II launch, planned for later this year, is a critical milestone that Park believes will enhance partnerships with major aerospace and defense firms in South Korea.
Industry Context
The commercial launch sector in South Korea is still emerging, with notable players like Hanwha Aerospace and startups such as Innospace and Perigee Aerospace also competing for market share. The global space launch market, valued at approximately $15 billion in 2023, is projected to grow significantly, reaching $41 billion by 2030.
Conclusion
As Unastella continues to develop its technology and expand its capabilities, it is well-positioned to contribute to South Korea's growing presence in the global space launch industry.
