Agenzia Spaziale Italiana

Agenzia Spaziale Italiana (ASI) is Italy's national space agency, established 1 January 1988 as a public body (ente pubblico nazionale) under dual oversight of the Ministry of University and Research and the Ministry of Defence. Headquartered in Rome, ASI coordinates Italy's civil and dual-use space activities spanning Earth observation, human spaceflight, space science, and launch technology.

In Earth observation, ASI's primary operational assets are the COSMO-SkyMed dual-use SAR constellation and the PRISMA hyperspectral mission. COSMO-SkyMed spans two generations: the original four-satellite X-band SAR fleet (CSK, launched 2007-2010, manufactured by Thales Alenia Space Italia) and the second-generation CSG system, which delivers substantially improved resolution with spotlight modes reaching 0.35 m across-track and full PolSAR capability. As of January 2026, three CSG satellites are in orbit (CSG-3 launched 2026-01-03 via Falcon 9), with CSG-4 in development. Commercial data distribution is managed through e-GEOS, a joint venture between Telespazio (80%) and ASI (20%). Both COSMO-SkyMed generations and PRISMA serve as ESA Copernicus Contributing Missions.^[1][2]

PRISMA (Hyperspectral Precursor of the Application Mission), launched March 2019 on a Vega rocket, is a 239-band imaging spectrometer covering 400-2505 nm at 30 m GSD across a 30 km swath, paired with a 5 m panchromatic channel. Its official designation as a "Precursor" reflects its technology demonstration role in pre-operational Italian hyperspectral capability. PRISMA had a planned 5-year design life from its March 2019 launch; according to ASI's website as of 2026-05-24, the mission continues to be presented as active, though no explicit life-extension announcement was confirmed in tier-1 sources.^[3][4]

ASI is leading the IRIDE Earth observation programme, a constellation of constellations (six sub-constellations combining radar and optical sensors) funded through Italy's PNRR and managed by ESA, with phased launches through 2028. ASI also contributes scientific instruments to international missions (CSES-LIMADOU HEPD particle detector with China) and is developing CALIGOLA, an atmospheric Raman LIDAR mission in collaboration with NASA Langley.^[5]

In human spaceflight, Italian industry has contributed over 40% of the ISS's habitable volume, including Node-2 Harmony, Node-3 Tranquility, the Cupola, and the Leonardo Permanent Multipurpose Module. Italy maintains active collaborations with ESA, NASA, JAXA, CONAE, and CNSA.
