Advancing LOX/LCH4 Dual-Propellant Cooling for HANBIT-Micro
INNOSPACE has successfully completed a series of combustion tests for its upgraded 4 kN-class liquid-methane kick-stage combustor for HANBIT-Micro.
Building on the 237-second long-duration ground test in May 2024, the combustor has been advanced with a Dual-Propellant Regenerative Cooling scheme.

 Unlike conventional single-propellant regenerative cooling, this approach utilizes both fuel and oxidizer as coolants, enabling:
 Reduced feed pressure requirements
 Lighter propellant tanks
 Lower overall kick-stage mass

 By preheating and vaporizing both coolants, the system also achieves:
 Improved mixing efficiency
 Shorter ignition delay
 Enhanced combustion stability and efficiency

 Overcoming High Technical Barriers
Most notably, the recent test validated stable regenerative cooling under low-pressure, subcritical conditions — a technically demanding regime — and mitigated the risks associated with using liquid oxygen (LOX) as a coolant.
The application of a gas–gas swirl injector further demonstrated improved mixing performance.

With this milestone, INNOSPACE continues to advance methane propulsion technology and enhance the maturity of the HANBIT-Micro kick-stage system.  Please stay tuned for the next phase of development.

 Global Media Spotlight on INNOSPACE

Following our global media visit, hosted by the spokesperson's office of the Ministry of SMEs and Startups(@bizinfo1357) on March 18, INNOSPACE has been featured by international press as a pioneering private space company in Korea.

The coverage highlighted INNOSPACE's hybrid rocket technology as a key differentiator—offering a simplified structure, enhanced safety, and cost efficiency compared to conventional liquid propulsion systems.

Following the successful launch of HANBIT-TLV in 2023, INNOSPACE secured valuable flight data through the first commercial launch attempt of HANBIT-Nano, continuing to advance the HANBIT launch vehicle family. Based on this, INNOSPACE is enhancing launch reliability and accelerating its entry into the global small satellite launch market.

With expanding partnerships across Europe and Latin America, the next HANBIT-Nano launch is scheduled for Q3 2026 at the Alcântara Space Center in Brazil, further strengthening INNOSPACE's global presence.

We appreciate the global media for their insightful coverage and continued interest.  INNOSPACE will continue to expand its global communication efforts.

INNOSPACE Establishes Satellite Business Division
Expanding beyond launch services, INNOSPACE has officially embarked on building an end-to-end space platform that covers the entire mission lifecycle—from satellite development and manufacturing to operations and data services.
Key Highlights
▪ Development of 3U CubeSat 'InnoSat-0' completed
▪ Dedicated infrastructure established for satellite development, manufacturing, testing, and operations
▪ Core technologies secured: ADCS, communications, power systems, and orbital control
▪ Launch aboard 'HANBIT-Nano' scheduled for Q3 2026

Leveraging its satellite development, integration, and testing infrastructure at the Cheongju Campus, INNOSPACE is strengthening its capabilities to deliver customized satellite solutions. The company also plans to expand into data services through integration with ground stations.
In the New Space era, INNOSPACE is evolving into a fully integrated space platform provider—connecting launch to data.
