PRISMA (PRecursore IperSpettrale della Missione Applicativa,[2] Hyperspectral PRecursor of the Application Mission) is an Italian Space Agency pre-operational and technology demonstrator mission focused on the development and delivery of hyperspectral products and the qualification of the hyperspectral payload in space.[3]
PRISMA is an Earth observation satellite with innovative electro-optical instrumentation which combines a hyperspectral sensor with a medium-resolution panchromatic camera collecting images at 30 m resolution within 30 km x 30 km scenes. The advantages of this combination are that in addition to the classical capability of observation based on the recognition of the geometrical characteristics of the scene, there is the one offered by hyperspectral sensors which can determine the chemical-physical composition of objects present on the scene. This offers the scientific community and users many applications in the field of environmental monitoring, resource management, crop classification, pollution control, etc. Further applications are possible even in the field of National Security.
PRISMA is a program completely funded by ASI and is a follow on of the cancelled HypSEO mission.[4] The satellite was launched on 22 March 2019 aboard a Vega rocket.[1]
The Hyperspectral / Panchromatic payload is derived from HypSEO and updated as for the JHM study:
