The Italian Space Agency satellite will observe the Earth using a hyperspectral optical sensor, which can open up new scenarios for the control of the environmental processes of our planet

ROME (Leonardo PR) — We are getting closer to the launch of the Italian Space Agency (ASI) mission PRISMA (Hyperspectral Precursor and Application Mission). The satellite will lift off from the European spaceport of Kourou in French Guiana the night between 8 and 9 March, aboard a VEGA rocket.

From its orbit, at about 620 kilometers of altitude, PRISMA will observe the Earth on a global scale with different eyes, being equipped with an innovative electro-optical instrumentation. The Italian satellite will look at the planet with the most powerful operative hyperspectral instrument in the world, able to work in numerous, narrow and contiguous bands arranged from the visible to the near infrared (VNIR, Visible and Near InfraRed) and up to the infrared shortwave ( SWIR, Short Wave InfraRed).
