Nuri Launch Vehicle and the Story Behind the Thermal Vacuum Chamber


Did you watch the recent launch of the Nuri launch vehicle?
Carrying a total of 13 satellites, Nuri successfully lifted off into space.


Developed entirely with domestic technology, Nuri is a mid-sized launch vehicle that has successfully carried out satellite deployment missions, marking an important milestone in the growth of Korea’s space technology and the expansion of the private space industry ecosystem.

Satellites launched aboard Nuri, however, must undergo extremely rigorous verification processes on the ground before heading into space.
This is because even the smallest malfunction cannot be tolerated in the harsh environment of space.

Space Equipment Designed to Withstand Extreme Environments


Space equipment such as satellites, launch vehicles, and space probes must operate reliably under extreme conditions, including high vacuum, high temperatures, and cryogenic temperatures, depending on mission requirements.

To verify this performance, a variety of tests that accurately simulate the space environment are conducted on the ground.
 These include bake-out tests, thermal cycling tests, and thermal vacuum tests.

Through these tests, engineers verify whether space equipment and components can maintain stable functionality under extreme conditions.


 A thermal vacuum chamber is the essential test facility required throughout this process.

Thermal Vacuum Chambers That Recreate the Space Environment


A thermal vacuum chamber creates a high-vacuum environment inside the chamber and uses a heat exchange system known as a shroud to reproduce the high-temperature and cryogenic conditions experienced by satellites in orbit.

This enables space environment testing on the ground, from individual components to full systems, allowing thorough verification of performance and reliability prior to launch.

Verification Before Reaching Space


Every piece of equipment destined for space must first secure reliability through rigorous ground-based testing before it reaches the launch pad.

Thermal vacuum chambers represent the starting point of this verification process, and MTES continues to set the standard for space environment testing through proven expertise and accumulated technical know-how.
