Defense Ministry Postpones Solid-Fuel Space Launch Due to Technical Glitch

The fourth test launch of a solid-fuel space launch vehicle, which was scheduled to take place off the coast of Jeju today (June 30), was postponed just before liftoff.

The Ministry of National Defense stated, "We decided to halt the launch for safety reasons after discovering some issues during final preparations for the solid-fuel space launch vehicle test scheduled for today."

The test launch was originally planned for around 2:00 p.m. today, but the decision to abort was made shortly before the scheduled time.

A defense ministry official said, "The launch was halted after a functional anomaly was detected during the final operational status check of the launch vehicle," adding that they are currently "investigating the specific cause."

A new date for the launch has not yet been set.

Weather conditions are typically the biggest variable in space launch vehicle tests.

As the monsoon season is arriving in the Jeju region starting today, the test launch of the solid-fuel space vehicle is expected to be delayed for some time.

A solid-fuel launch vehicle is a space rocket that uses solid propellant instead of liquid fuel.

Solid-fuel rockets have the advantages of a simpler structure, ease of storage and handling, a short preparation time of less than seven days for rapid deployment, and lower launch costs compared to liquid-fuel rockets.

For these reasons, solid-fuel launch vehicle technology also has high military utility.

Following the lifting of the ROK-U.S. missile guidelines in May 2021, which removed restrictions on solid-fuel propulsion for space launch vehicles, the South Korean military began developing the technology under the lead of the Agency for Defense Development (ADD). The military has conducted three successful test launches so far: the first in March 2022, the second in December 2022, and the third in December 2023.

The South Korean military authorities plan to use the domestic solid-fuel space launch vehicle to launch ultra-small reconnaissance satellites into space in the future.
