From spy satellites to cell networks, South Korea hopes new rocket will get house programme off floor

South Korea plans to check its first domestically produced house launch car subsequent week, a serious step towards jumpstarting the nation’s house programme and reaching formidable targets in 6G networks, spy satellites, and even lunar probes.
If all goes nicely, the three-stage NURI rocket, designed by the Korea Aerospace Research Institute (KARI) to ultimately put 1.5-ton payloads into orbit 600 to 800km above the Earth, will carry a dummy satellite tv for pc into house on Thursday.
South Korea’s final such booster, launched in 2013 after a number of delays and a number of other failed exams, was collectively developed with Russia. The new KSLV-II NURI has solely Korean rocket applied sciences, and is the nation’s first domestically constructed house launch car, mentioned Han Sang-yeop, director of KARI’s Launcher Reliability Safety Quality Assurance Division. “Having its own launch vehicle gives a country the flexibility of payload types and launch schedule,” he informed Reuters in an e mail.
Military and civilian advantages
It additionally offers the nation extra management over “confidential payloads” it could need to ship into orbit, Han mentioned. That might be necessary for South Korea’s plans to launch surveillance satellites into orbit, in what nationwide safety officers have referred to as a constellation of “unblinking eyes” to observe North Korea.
So far, South Korea has remained nearly completely reliant on the United States for satellite tv for pc intelligence on its northern neighbour.

In 2020 a Falcon 9 rocket from the U.S. agency Space X carried South Korea’s first devoted army communications satellite tv for pc into orbit from the Kennedy Space Center in Florida.
NURI can also be key to South Korean plans to ultimately construct a Korean satellite-based navigation system and a 6G communications community. “The program is designed not only to support government projects, but also commercial activity,” Oh Seung-hyub, director of the Launcher Propulsion System Development Division, informed a briefing on Tuesday.
South Korea is working with the United States on a lunar orbiter, and hopes to land a probe on the moon by 2030.
Trial launch
Given issues with earlier launches, Han and different planners mentioned they’ve ready for the worst. The launch day could also be modified on the final minute if climate or technical issues come up; the craft will carry a self-destruct mechanism to destroy it if it seems it gained’t attain orbit; and media gained’t be allowed to look at the check straight.
At least 4 check launches are deliberate earlier than the rocket might be thought of dependable sufficient to hold an actual payload. According to pre-launch briefing slides, the rocket’s deliberate path will take it southeast from its launch website on the south coast of the Korean peninsula, threading its approach over the ocean on a trajectory geared toward avoiding flying over Japan, Indonesia, the Philippines, and different main land plenty.
“This upcoming launch may be remembered as the hope and achievement of Korean rocketry historically no matter the launch is successful or not,” Han informed Reuters.
Sensitive expertise
Space rockets on the Korean peninsula have been fraught with considerations over their potential use for army functions, leaving South Korea’s efforts lagging extra succesful programmes in China and Japan.
“Modern rocketry in Korea couldn’t devote its capability much in R&D of rockets because of long-standing political issues,” Han mentioned. The United States has considered North Korea’s personal satellite tv for pc launch automobiles as testbeds for nuclear-tipped intercontinental ballistic missile expertise. A North Korean house launch in 2012 helped result in the breakdown of a cope with the United States.
“North Korea, of course, will not look favourably on South Korea’s rapidly advancing space capabilities, which are far more technologically advanced than those possessed by the North,” mentioned James Clay Moltz, an area programs professional on the U.S. Naval Postgraduate School.
South Korea’s push into house comes because it speeds forward with its personal army ballistic missile programs after agreeing with the United States this yr to finish all bilateral restrictions on them.
“There is no concern on military applications in NURI launch vehicle development,” mentioned Chang Young-keun, a missile professional on the Korea Aerospace University. Unlike the liquid-fuelled NURI, South Korea’s army missiles use stable gas, which is healthier for weapons, he added.
South Korea isn’t seen as a “threat” by both Russia or China, so it appears unlikely to have an effect on their house packages, that are already extremely militarized, Moltz mentioned. “Many space launch technologies are inherently dual-use,” he mentioned, however famous that he hopes NURI’s growth will “not lead to an arms race in space, but instead a safer ‘information race’” the place South Korea has higher intelligence to move off any future disaster.
