Execution over perfection. Experimentation over analysis. Within three years of its founding, UNASTELLA attempted its first launch. Guided by “Right Now, Right Here” and “Learning by Burning,” we are transforming the speed and cost structure of space development through rapid execution and iterative learning. Our willingness to act without fear of failure is our greatest asset.

UNASTELLA designs and manufactures every core propulsion component in-house, including igniters, combustors, and electric motor pumps. Our engine is the world’s highest-thrust electric pump-fed liquid rocket engine, proving what electric propulsion can achieve beyond its perceived limits. The engine is our heart, and technology is our language.

UNASTELLA has built a technology formula designed for success. Our chosen kerosene and liquid oxygen propellant combination is a global standard proven through more than 5,000 launches. Electric motor pumps simplify engine architecture, reducing development and operational risk through practical innovation. By combining these technologies, UNASTELLA has designed a system built for both launch success and commercialization.

Speed comes not from willpower, but from structure. Korea’s industrial ecosystem is built to support the pace required for launch vehicle development. With design, manufacturing, and testing infrastructure concentrated within a 200 km radius, UNASTELLA can iterate rapidly through daily feedback and decision-making, shortening development cycles while naturally reducing technical risk. Combined with competitive labor and logistics costs compared with the U.S., 30 years of accumulated rocket development experience, and a world-class advanced components and materials supply chain, UNASTELLA is building launch vehicles quickly, reliably, and cost-effectively.
A complete system is built through focus and prioritization. UNASTELLA’s philosophy begins with clearly distinguishing what is essential from what is optional. We focus on engine development and system integration, which determine launch vehicle performance and reliability, while actively leveraging proven external resources and partners in other areas. Like the fabless model in semiconductors, we focus on our core strengths to raise the quality of the entire system and maintain development speed with minimal facility investment and lean teams.

UNASTELLA is the only private company to have secured both launch licensing and a launch site within South Korea. We have built an end-to-end system spanning design, testing, and launch across Yeoju, Daejeon, and Goheung. We are the only private rocket company capable of launching from Korea.

UNASTELLA works with a leading expert network at the center of Korea’s space ecosystem. We are strengthening our core capabilities through advisory support from former KARI experts and technology transfers from KARI, while receiving program collaboration and policy and technical support from KASA. This network, combining public-sector experience with private-sector innovation, is what enables UNASTELLA to move faster and more safely toward space.

Stella Story
At 11:50 PM on May 28, a small launch vehicle, 9.45 meters long and weighing 2 tons in total, equipped with a 5-ton-thrust engine, successfully completed a test launch at its own launch site in Bongnae-myeon, Goheung-gun, Jeollanam-do.
2025. 05. 29
At 6:00 PM on April 23, 2025, Unastella successfully completed the single-engine qualification test (Static Hot Fire Test / Stage Qualification Test), the final milestone before the second launch campaign, at its own launch site in Yeompo Village, Oenarodo, Goheung-gun, Jeollanam-do.
2025. 04. 24
At 3:00 a.m. on November 23, 2024, Una Stella’s first launch campaign since its founding came to an end. As the first attempt to launch a private rocket within the territory of the Republic of Korea, it marks an important milestone reached 2 years and 9 months after the company’s establishment.

Media
Hosted by the Korea AeroSpace Administration and the Ministry of Foreign Affairs… Over 40 domestic space companies participated
Met with procurement and purchasing managers… Held 60 meetings with overseas space agencies
As you saw earlier, from the perspective of South Jeolla Province, this Nuri launch, carried out with a private-sector focus, drew more attention. That is because Goheung has the potential to become the center of the space launch vehicle industry. What efforts are needed for success? Visiting K news anchor Kim Dae-young listened to voices from the scene.
The Korea AeroSpace Administration is moving forward with procedures to open the Naro Space Center to private use.
On the 19th, the Korea AeroSpace Administration held a meeting at its headquarters with representatives from private companies that hope to use the Naro Space Center, chaired by Deputy Administrator Noh Kyung-won. The meeting was attended by launch vehicle development companies including the Korea Aerospace Research Institute, as well as △Unastella △Innospace △Perigee Aerospace, who exchanged views on the ‘Guide to Procedures for Private Companies Using the Naro Space Center.’
