South Korea has unveiled an ambitious plan to establish a low-Earth orbit (LEO) satellite communications network comprising hundreds of satellites by 2035, while also pulling forward its first lunar landing mission to 2030 — two years ahead of the original schedule. The plans were approved by the National Space Council, chaired by President Lee Jae Myung, on 4 July 2025.

The LEO Network Plan

The Korea AeroSpace Administration (KASA) unveiled the strategy during a public briefing on advanced industry development held in Jinju, a city in the southeastern part of the country. The network is envisioned as South Korea's own version of SpaceX's Starlink constellation and is intended to strengthen the country's domestic satellite and launch vehicle manufacturing ecosystem.

KASA Administrator Oh Tae-seok said, 'Leading space nations are making all-out efforts to build low-Earth orbit satellite communications networks, which are critical infrastructure for safeguarding national security and communications sovereignty, as well as a strategic foundation for the 6G era.' The statement underscores Seoul's view that space-based connectivity is no longer optional — it is a matter of sovereign infrastructure.

Accelerated Lunar Mission Timeline

Rather than waiting for South Korea's next-generation launch vehicle — scheduled to make its debut in 2032 — the government has decided to send a privately developed small lunar lander aboard the three-stage Nuri rocket in 2030. This pragmatic workaround reflects a broader urgency to establish a credible lunar presence within the decade.

KASA has also outlined a phased lunar exploration roadmap: a lunar communications orbiter is planned for launch in 2029, followed by the crewed-precursor lunar lander in 2030, and an Earth-moon scientific exploration probe in 2031. Together, these missions are designed to lay the groundwork for an expanded long-term lunar programme.

European Space Cooperation Push

In a parallel diplomatic initiative, South Korea is dispatching a public-private delegation to Europe to deepen space sector ties. The delegation, jointly organised by the foreign ministry and KASA, will hold a series of 'Space Day' events in Belgium, Romania, and Poland. The outreach targets members of the European Union (EU) and the North Atlantic Treaty Organization (NATO), as well as key Eastern European nations — a signal that Seoul is actively internationalising its space ambitions beyond its traditional partners.

Why This Matters

South Korea's twin announcements place it firmly in the global race for LEO dominance and lunar presence. The LEO network directly addresses 6G readiness and national security communications — two areas where dependence on foreign infrastructure is increasingly seen as a strategic liability. Notably, this is the first time Seoul has formally committed to a Starlink-scale domestic constellation, marking a significant escalation in its space policy ambitions. The accelerated lunar timeline also positions South Korea to compete with regional peers, including Japan, China, and India, all of whom have active lunar programmes targeting the same decade.

With presidential-level endorsement and a concrete multi-mission roadmap now in place, the next test will be whether KASA can translate policy ambition into hardware on schedule.
