South Korea launches homegrown Nuri rocket in major space milestone

South Korea successfully launched its first homegrown rocket on Tuesday, deploying a satellite into low-Earth orbit in a major milestone as the country jumps into the space race with both commercial and military implications.

The three-stage Nuri rocket blasted off from the Naro Space Center in the southern coastal town of Goheung on Tuesday afternoon. It reached its target altitude of 435 miles and released a 360-pound performance verification satellite as well as a 1.3-ton dummy satellite, South Korea's Ministry of Science and ICT said.

"Today is a very monumental day in South Korean history," science minister Lee Jong-ho said at a press briefing after the launch. "The sky has opened up for us and we made a great step forward in space exploration."

With the launch, South Korea became the tenth country to send a satellite into space with its own technology. It is the seventh country to develop a space launch vehicle that can carry a satellite of more than 1 ton, following the United States, China, Japan, France, Russia and India.

"It is meaningful that we don't have to borrow other nation's rockets anymore," Lee added. "We can do it on our own. [Today's launch] will become a stepping stone to the next space era."

Directly outside of the space center, dozens of spectators found spots among the rocky coastline to take in the spectacle, cheering loudly as the rocket rumbled and then appeared from behind a low mountain before climbing into a bright blue sky.

The launch was the second liftoff for the 2-ton Nuri rocket, also known as the Korean Space Launch Vehicle II, after a mission in October failed to successfully deliver a dummy satellite. South Korea has spent more than $1.5 billion developing Nuri since 2010 and has four more launches scheduled through 2027.

Lee Sang-ryool, head of the Korea Aerospace Research Institute, said after the launch that all phases proceeded normally and that satellites were deployed at "exactly the intended altitude and speed."

KARI confirmed that the satellite successfully communicated with a South Korean research station in Antarctica roughly 40 minutes after launch.

Tuesday's accomplishment was not just a technical exercise. Seoul has prioritized space technology as a growth industry and the government has laid out a roadmap to deploy next-generation communications and navigation satellites. The science ministry has said it will transfer launch vehicle technologies to the private sector to help spur development.

South Korean President Yoon Suk-yeol praised Tuesday's successful launch and said "the dreams and hopes of the Korean people now extend into space." In a video call with researchers, Yoon vowed to create an aerospace agency to further develop the industry.

The country is also looking to space to bolster its defense capabilities amid a growing arms race on the Korean Peninsula.

South Korea has previously relied on the U.S. military to monitor the North, but Seoul has signed a contract with Elon Musk's SpaceX to launch five spy satellites by 2025, with the first launch on a Falcon 9 rocket in 2023. Much of the activity in South Korea's space sector comes on the heels of an agreement with the United States last year to end decades-long restrictions on Seoul's missile development.

The restrictions, which were first introduced in 1979, originally limited South Korea-developed rockets to a flight range of around 110 miles and a payload of 1100 pounds. The guidelines were revised multiple times over the years until they were finally lifted in May 2021 during a summit between U.S. President Joe Biden and then-South Korean President Moon Jae-in.

While North Korea has stayed in the spotlight with a flurry of weapons tests since the beginning of 2022, South Korea has shown off military hardware of its own, including a submarine-launched ballistic missile and a supersonic cruise missile.

In March, the military successfully tested its first home-produced solid fuel rocket, a boost to its space-based defense capabilities.

South Korea's space ambitions also extend to the moon. The country is scheduled to launch its first lunar orbiter in August aboard a SpaceX rocket, and is aiming to send a landing module to the moon using South Korean rockets by 2031.

Go ahead for second round of micro-launcher payload competition
Berlin, Germany (SPX) Jun 22, 2022
On 20 June 2022, the German Space Agency (DLR) launched the second round of its competition for zero-cost flights of small satellites on microlaunchers developed and constructed in Germany. This marks the start of the implementation phase for a total of three additional flights being offered by the space companies Isar Aerospace Technologies GmbH and Rocket Factory Augsburg AG in 2023 and 2024. This time, the competition is not only aimed at European institutions, but also at start-ups and small and med ... read more
