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.

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.

As SpaceX counts down to what could be the largest IPO in history, the race to build the next generation of launch vehicles is heating up. Asia wants in. Startups across Australia, India, Japan, and South Korea are racing to establish themselves in a market long dominated by the U.S. and China.
One of them is Unastella, a four-year-old South Korean startup that just closed a $24 million Series B, bringing its total funding to $44 million. The company launched its own rocket, the Una Express-I, from South Korean soil in May 2025.
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 will proceed with procedures to open the Naro Space Center to the private sector. On the 19th, the Korea AeroSpace Administration held a meeting at its office chaired by Deputy Administrator Noh Kyung-won with representatives from private companies hoping to use the Naro Space Center.
