SEOUL - South Korea said on Thursday it had successfully launched its home-grown Nuri rocket and placed working satellites into orbit, hailing a key step forward for the country’s burgeoning space programme.

It was the third launch of the Nuri, which successfully put test satellites into orbit in 2022 after a failed 2021 attempt saw the rocket’s third-stage engine burn out too early.

The three-stage rocket, more than 47m long and weighing 200 tonnes, soared into the sky at 6.24pm (5.24pm Singapore time) from the Naro Space Centre in South Korea’s southern coastal region, leaving a huge trail of white smoke.

“We report to the public that the third launch of Nuri, which was independently developed to secure domestic space transportation capacity, has been successfully completed,” said Mr Lee Jong-ho, minister of science and technology.

The main satellite made communication with South Korea’s King Sejong Station in Antarctica, he said, adding that the launch confirmed “our potential for launch services for various satellite operations and space exploration”.

South Korea will carry out three more launches of Nuri by 2027, Mr Lee added.

South Korean President Yoon Suk-yeol hailed Nuri’s launch, saying it will give the country a competitive edge in the global space race.

“The success of Nuri’s third launch is a splendid achievement that declares South Korea has joined the G-7 space powers,” he said in a statement.

The launch came a day after initial plans were called off over a computer communication error, which was resolved by Thursday.

In previous tests, the rocket carried payloads mainly designed for verifying the performance of the launch vehicle.

This time, the rocket was topped with eight working satellites, including a “commercial-grade satellite”, according to the science ministry.
