South Korea’s second test launch of its domestically produced Nuri rocket successfully placed several satellites in orbit on Tuesday, officials said, taking a major step in efforts to jumpstart its space program after a first test failed last year.
The rocket lifted off from Naro Space Center on the southern coast of South Korea at 4 p.m. (0700 GMT). A 162.5-kg (358 lb) satellite designed to verify the rocket’s performance successfully made contact with a base station in Antarctica after entering orbit, officials said.
The rocket also successfully placed a 1.3-ton dummy satellite and four small cube satellites developed by universities for research, into orbit.

“The sky of the Korean universe is now wide open,” Science and ICT Minister Lee Jong-ho told a briefing. “Our science and technology has made great strides.”
The three-stage KSLV-II Nuri rocket, designed by the Korea Aerospace Research Institute (KARI) to eventually put 1.5-ton payloads into orbit 600 to 800 kilometers (370 to 500 miles) above the Earth, is a cornerstone of the country’s ambitious goals for 6G networks, spy satellites, and even lunar probes.
It uses only Korean rocket technologies, and is the country’s first domestically built space launch vehicle. South Korea’s last booster, launched in 2013 after multiple delays and several failed tests, was jointly developed with Russia.
President Yoon Suk-yeol watched the launch from his office and thanked everyone involved as he was briefed by Lee and others about the success, vowing to keep an election pledge to create a new agency to take charge of space affairs, according to a statement by his office.
“Now the road to space from our land has been opened,” Yoon said. “It was the product of 30 years of daunting challenges. From now on, the dreams and hopes of our people and our youth will extend into space.”
In Nuri’s first test in October, the rocket completed its flight sequences but failed to put the test payload into orbit after its third-stage engine burned out earlier than planned.
Engineers adjusted the helium tank inside Nuri’s third-stage oxidizer tank to address that problem, Yonhap news agency reported.
KARI has said it plans at least four more test launches by 2027. Nuri is key to South Korean plans to eventually build a Korean satellite-based navigation system and a 6G communications network. The country also plans to launch a range of military satellites, but officials deny the Nuri has any use as a weapon.
South Korea is also working with the US on a lunar orbiter, and hopes to land a probe on the moon by 2030.
After Tuesday’s successful launch, the US Embassy in Seoul said on Twitter it is looking forward to US-South Korea cooperation in space.
Space launches have long been a sensitive issue on the Korean peninsula, where North Korea faces sanctions over its nuclear-armed ballistic missile program.
In March, South Korea’s military separately oversaw what it said was its first successful launch of a solid-fuel space-launch rocket, another part of its plans to launch spy satellites.
In recent years, South Korea and the US agreed to scrap bilateral limits on Seoul’s missile and rocket development, clearing the way for new civilian and military launches.
