Korea's first homegrown space launcher

Space Hub is the leading launch solution provider in Korea with technology accumulated from decades of legacy in propulsion system and now extending its work scope to the system integration since selected as the system integrator of Nuri (KSLV-II).

The Nuri (KSLV-II) is the space launcher wholly developed with Korean technology. The launcher is 3-staged and generates 300 tons of thrust to fight the gravity and capalbe to carry 1,500kg (SSO) of payload. We developed its vital parts and infrastructure such as its engines are test facilities.

Core Components

Engine Clustering

By combining and balancing the four 75t engines as they operate as one engine, Nuri generates a total of 300-ton thrust to liftoff the ground.

The 75t liquid engine is capable to endure extreme conditions from -180C to 3,330C.

Altitude Control System (ACS)

Hanwha's ACS (Altitude Control System) enables space launchers to bradjust the flight direction

Space Hub supplied total 1,473 parts for Nuri's propulsion system alone

Launcher: The Next Generation

The great challenge of
Space Hub to become
a space leader to embrace
the New Space Era

Space Hub is advancing launcher technologies in preparion of
more advanced next generation rockets including KSLV-III.
We will expedite our research in order to catch up space leaders
and pave the way for Korea to join the space club as a new
strong contender.

01 Reusable Launch Vehicle (RLV)

To meet the growing demand for satellite launching, countries around the world are
attempting to launch their space launchers faster and more cheaply. As the trend,
leading countries such as the United States, France, and Germany, etc. are focusing
their efforts on securing the technology for reusable launch vehicle (RLV) by
discovering innovative private companies to meet the explosive growth of demand in
space transportation and to reduce the expenses considerably.

Through the development of next-generation space launcher, Korea is providing the
foundation for advancing into a space power by promoting the development of 100-ton/
10-ton multi-stage combustion cycle engine mounted with RLV-based technology such
as re-ignition and thrust control. Space Hub signed a research agreement with a
consortium of 13 schools represented by Seoul National University, with a project on the
research center specializing in RLV sophistication technology performed to take on the
challenge of becoming the first private space company in Korea to develop RLV
sophistication technology.

02 Next-Generation Propellant

Beyond the traditional propulsion unit's requirements of "reliability, performance, and
stability," the next-generation propulsion unit requires "reuse, re-ignition, diagnosis,
multi-purpose utilization, and eco-friendliness," and developing the next-generation
propellant satisfying these requirements is an essential factor in the plan for space

Liquid Oxygen-Methane is a propellant is superior to kerosene and hydrogen in order
to develop RLV. Accordingly, countries such as Russia and private companies such as
Space X and Blue Origin are planning to use liquid oxygen-methane as the next-
generation propellant.

Space Hub will also contribute to the further advancement of Korea's space
rocket technology.

03 3D Printed Rocket

Private companies in the "New Space Era" are utilizing 3D printing technology to reduce the cost to
access space. Space X is advancing their RLV (Reusable Launch Vehicle) and new stars such as Rocket
Lab and Relativity Space, etc. are utilizing 3D printing technology to manufacture more affordable
launchers. Especially, Relativity Space's Terran 1 the world's first 3D printed rocket is expected to
become a game-changer if it proves its stability.

Korea will also investing in 3D printing technology for space launchers and Space Hub will
drive that innovation at the forefront.
