This year, after the launch of the Naro in 2013, a projectile made with pure domestic technology will fly from our land eight years later.

In addition, the next-generation mid-size satellite will also be launched which will open the era of civil satellite development and the Arirang 6, which can observe land in all kinds of weather.

Reporter Kim Jin-du reports.

From the Goheung Space Center, Lake Naro rises into the sky with flames.

It is a successful launch after 3 failures and delays.

Although a Russian-made single-stage rocket was used, this is the first case of completing and launching a projectile on our land.

After that, the quiet space center will be busy again after eight years in October this year.

This is because the first space launch vehicle made with pure national technology, the Nuri, is being tested.

It was scheduled to launch in February, but was delayed eight months due to delays in assembling the first-stage rocket core.

In March of this year, seven months before this, the next-generation mid-size satellites are heading into space.

It weighs half the weight of a large satellite like Cheonlian, but it has a competitive advantage with a high-performance camera.

In order to foster domestic satellite development companies, Hang Woo-yeon is in charge of Units 1 and 2, while Units 3 and 5 are developed by the private sector.

At the end of the year, the all-weather Arirang 6 ground-observation satellite will be launched.

The camera resolution of No. 6 is 50 cm, twice that of No. 5.

It is a technology owned exclusively by satellite powers such as the United States, China, Japan, Europe (EU) and Russia with the ability to separate terrestrial objects at least 50 cm away from 500 km in the air.

If the plans scheduled for this year are carried out successfully, Korea is expected to become the world’s first country with its own launch vehicle technology after a satellite powerhouse.
