SEOUL – South Korea says it has successfully launched a small but functional satellite into orbit. Its first domestic rocket On Tuesday, it brought the country closer to its dream of becoming a new player in the space industry and deployed its spy satellites to better monitor North Korea.

Three steps نوری۔ The rocket, built by the government’s Korea Aerospace Research Institute in collaboration with hundreds of local companies, was launched at 4 pm on Tuesday from the Narrow Space Center in Goyeong, on the southwestern tip of South Korea.

Seventy minutes after the lift off, South Korea announced that it had succeeded in its mission to launch a 353-pound Nouri working satellite as well as a 1.3-ton dummy satellite into orbit 435 miles above the ground. .

It was a moment of national pride, with all the major TV stations in the country taking off live YouTube At the time of the launch of the Science Channels, the government and local media described the Nouri mission as an important event through which South Korea would make its mark. Space technology, the latest high-tech market Where the country has decided to become a player.

“South Korea’s science and technology has taken a big step today,” said Lee Jong-ho, the government’s Minister of Science and Technology, announcing the mission’s success during a national television news conference. “We have laid the groundwork for launching our own satellites whenever we want. We will no longer have to rely on rockets and launch stations from other countries.”

For decades, South Korea has grown its desire to join the elite clubs of countries capable of launching communications and other satellites into orbit using domestic rockets. It also wanted to send its surveillance satellites into space to better monitor the growing nuclear and missile threat from North Korea.

After many delays and failures, South Korea to pour For the first time in 2013, a satellite was sent into orbit for research and development purposes. But the two-stage rocket used for the mission – Naro – was built in conjunction with Russia. South Korea has spent about 1.9 trillion won ($ 1.5 billion) to produce 200 tons of light with its technology, also known as the Korea Space Launch Vehicle-II.

At Nouri’s first test launch last October, the rocket launched a 1.5-ton dummy satellite into space 434 miles above the ground. But it caused a problem in its oxidizer tank and soon burned to ashes, failing to stabilize the dummy satellite and give it enough speed to stay in orbit.

At its second test launch on Tuesday, Nouri was carrying not only a 1.3-ton dummy satellite but also a 357-pound performance-confirming satellite. This is the first time that South Korea has launched a real working satellite on a domestic rocket.

Ahan Sang-il, a senior researcher at the Korea Aerospace Research Institute, said that in the future, performance-verifying satellite scientists will be able to test antennas, generators and other components of the satellite and transmit data about its speed to Earth. The satellite will help prepare for launch. .

Four cube sets, mini-research satellites with performance verification satellites, made by South Korean universities. It weighs 7 to 21 pounds and will be launched into orbit one by one from June 29.

South Korea plans to launch four more tests of the light system by 2027, including a schedule early next year. It is also developing a new rocket twice as powerful as light. The country aims to land unmanned spacecraft on the moon using its rockets until the early 2030s.

South Korea hopes to use its rocket technologies to build satellite-based navigation and next-generation communications networks. It also wants to capture a share of the world’s satellite launch market. The United States, Russia, France, China, Japan and India have launched the most rockets worldwide.

So far, South Korea has relied on other countries to carry its satellites. South Korea used the SpaceX Falcon 9 rocket, founded by Elon Musk, to orbit its first military communications satellite in July last year. It plans to launch into the moon this autumn, also on the Falcon 9 rocket.

Tuesday’s launch highlighted the arms race on the Korean Peninsula. South Korea does not have a military spy satellite, relying on US satellites to view North Korea. As North Korea’s missile threats increase, however, South Korea wants to keep its “eyes and ears” in space using its rockets.

North Korean leader Kim Jong Un said at a Workers’ Party meeting last year that his government had completed the design of a military spy satellite. He said his country would deploy a satellite in the near future.

UN Security Council Ban on sending space rockets to North Korea He said they were used by Pyongyang to develop long-range ballistic missiles. North Korea violates the ban Launched satellite spacecraft. It had earlier successfully tested three intercontinental ballistic missiles in 2017.

between February 27 And May 25According to US and South Korean officials, it conducted six missile tests involving ICBMs or ICBM components. In the first two tests, North Korea said it was testing a satellite launch vehicle.

North Korea has accused South Korea and the United States of “double standards” in expanding its space program, while denouncing North Korea’s space programs as the core of its weapons program.
