# PRISMA HSI (Hyperspectral Imager)
*sensor . products*

Pushbroom dual-detector hyperspectral imaging spectrometer on the PRISMA satellite, operated by the Italian Space Agency (ASI). 239 contiguous channels covering 400-2505 nm (66 VNIR channels at 400-1010 nm plus 173 SWIR channels at 920-2505 nm), 30 m GSD, 30 km swath, 12-bit quantization. Co-registered panchromatic channel at 5 m GSD. Launched 22 March 2019; the earliest of the three full-VNIR-SWIR civilian hyperspectral missions in routine operation. SWIR coverage to 2505 nm spans the diagnostic absorption features of clay, carbonate, sulphate, and phyllosilicate alteration minerals central to mineral exploration targeting.
