Space economy and strategic development in ASEAN pathways to 2035

The ASEAN space economy is entering a decisive scaling phase toward 2035. Building on a global market projected to reach USD 1.8 trillion by 2035 at ∼9% CAGR, up from USD 630 billion in 2023, ASEAN's contribution is expected to expand from an estimated 4–11% share to a comparable range of the much larger 2035 total, equivalent to roughly USD 80–200 billion under plausible growth paths. Three reinforcing engines propel regional upside: (i) Earth Observation (EO) commercialization for climate, agriculture, infrastructure and ESG finance—whose value in Southeast Asia is projected to triple from USD 15 billion (2023) to USD 45 billion by 2030; (ii) SATCOM expansion through high-throughput systems and universal service programs (e.g., Indonesia's 150-Gbps SATRIA-1); and (iii) security-driven Intelligence, Surveillance and Reconnaissance (ISR) and Space Domain Awareness (SDA) demand that catalyzes downstream analytics and dual-use constellations. This paper synthesizes evidence from global baselines and ASEAN country plans, and aligns them with a Space Capacity Ladder (SCL) for policy, infrastructure, human capital, and technology. Thailand emerges as a regional hub candidate through THEOS-2 EO operations and Thaicom's commercial platforms, the Space Affairs policy program, and the Spaceport Thailand concept spanning Narathiwat (GEO/Equatorial access), Ranong, and Kanchanaburi (SSO), enabling multi-orbit services, test, and integration facilities (AIT), including the PPP-anchored industrialization. These strategic directions frame a regional pathway from user status to co-producer status in upstream and downstream segments, including launch-adjacent logistics, data infrastructure, and carbon markets. Methodologically, we construct a bottom-up ASEAN forecast by segment (Services, Ground, Manufacturing/Launch, and Non-Satellite), applying segment-specific growth rates, ASEAN readiness multipliers from the SCL, country-level policy, and investment pipelines. Under conservative assumptions, ASEAN sustains a 4.4–11.1% slice of the 2035 global space economy, with EO, SATCOM, and ISR accounting for the preponderance of value creation and Thailand, Indonesia, Vietnam, Malaysia, Singapore and the Philippines driving most incremental capacity.
