to launch a rocket into space, other countries have been using the solid fuel our country has studies could not even due to ROK missile guidance. But this time the guidelines have been completely solved. With a little improvement, I think it would be possible to go to the moon with a Korean projectile.

This is a shot of the European Aryan-5 rocket launch in February of this year.

On both sides of the rocket is an auxiliary propellant that uses solid fuel.

After exhaling flames and lifting the rocket into space, the propellant falls to the sea.

Although it is a global trend to use these auxiliary propellants to obtain great propulsion, the projectiles we are developing are simply cylindrical, as we cannot use solid fuel.

But it will be different in the future.

[Koh Jung-hwan/Hang Woo-yeon, Head of the Korean Launch Vehicle Development Project: If a solid booster (auxiliary propellant) is used, the performance can be further improved to increase the weight we can send.]

Korea is aiming to launch a probe in 2030.

To this end, the Nuri is being developed in-house, but the flight distance was limited because it is a three-stage rocket that uses only liquid fuel.

Adding an auxiliary propellant that uses solid fuel can solve this problem.

[Takminje/KAIST Aerospace Engineering Professor Emeritus: When exploring the moon, if I attach a solid rocket now, I think it will be possible to return a sample (recovery of the moon) from there.]

Solid fuel engines are easier to develop than liquids, and are cheaper than a tenth.

[Park Soo-Kyung/ Blue House Science and Technology Adviser: Defense companies that have accumulated solid fuel rocket technology are now able to enter the mid- to long-range civilian projectile market.] As it

already has the technology, it is possible to develop a rocket that uses only solid fuel like Japan. It's no different from the ballistic missile ICBM, so it could be a military controversy.
