PRISMA Promises Revolution in Earth Observation, Environmental Monitoring
January 31, 2019 Doug Messier

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).

PRISMA is a program funded by ASI and represents a global excellence, which highlights the capabilities of Italy to provide a “turn-key” space system, from planning to implementation, from launching to ground data management. PRISMA was developed by a Temporary Joint Venture of companies, led by OHB Italy, responsible for the mission and management of the three main segments (land, flight and launch), and Leonardo, which built the electro-optical instrumentation. The launch will take place aboard the ESA’s launcher designed and conceived in Italy: VEGA produced by AVIO. Telespazio set up the mission control center, while data acquisition and processing will take place at the Matera Space Centre.

The mission will be able to offer an unprecedented contribution to the observation of natural resources from space and to the study of main environmental processes (e.g. interactions between the atmosphere, the biosphere and the hydrosphere, observation of environmental and climate changes on a global level; aftermath of anthropic activities on ecosystems). Regarding the fields of application, PRISMA will be able to provide valuable information to support prevention of natural hazards (such as hydrogeological) and anthropic (including soil pollution), monitoring of cultural heritage, aid actions to humanitarian crises, agricultural activities and exploitation of mineral resources.

Unlike the passive satellite sensors currently operating, which record the solar radiation reflected by our planet in a limited number of spectral bands (typically a dozen at most) PRISMA would be able, thanks to the instrumentation on board, to acquire 240 bands (239 spectral bands and the panchromatic channel). This will allow to refine our knowledge concerning natural resources and environmental processes in progress, such as the phenomena linked to climate change.

PRISMA represents the perfect synthesis of an industrial system, of research and complete planning. An industrial team composed of:

OHB Italy is responsible for managing the entire program and mission, system engineering, design, platform development and integration and all satellite validation activities. The satellite has been integrated at the OHB Italy facilities in Tortona, Alessandria.

Leonardo has designed and built in Campi Bisenzio (near Florence) PRISMA’s electro-optical payload, which includes, in addition to a color camera, the world’s most powerful hyperspectral instrument currently operating for Earth observation. Also from Campi Bisenzio comes the star tracker that will allow the satellite to navigate in space, while in Nerviano (near Milan) Leonardo has realized PRISMA’s solar panels and power supply unit.

Telespazio (Leonardo 67%, Thales 33%) has realized the Ground Segment – which comprehends the mission control center at Fucino (L’Aquila) and the data acquisition and processing center in Matera – and will manage LEOP (Launch and Early Orbit Phase) and in-orbit test activities. Finally, Thales Alenia Space (Thales 67%, Leonardo 33%) has implemented the data transmission system on board the satellite.

VEGA will be the ESA launcher that will bring PRISMA into orbit. It will be launch number 14 for the vector made by AVIO, a company international group leader in the field of space launchers, in propulsion and space transport. AVIO is the prime contractor for Vega, the space launcher designed to carry satellites in low Earth orbit (LEO-Low Earth Orbit), which has allowed Italy to have direct access to space. AVIO manages VEGA’s industrial supply chain, which includes companies from seven different European countries. VEGA is developed and manufactured for 65% in Italy, while the remaining 35% of production activities are spread among Spain, Belgium, the Netherlands, Switzerland, Sweden and France.

I think this "Revolution in Earth Observation"  will find different uses soon.
Or the technology is already used in some special satellites. We just do not know.

The Italian Space Agency’s PRISMA Earth observation satellite is “fit” for its Arianespace Vega launch

The PRISMA satellite on Arianespace’s upcoming Vega mission has completed a key step in its pre-launch checkout process, which will enable this Italian Earth observation platform to be orbited in mid-March from French Guiana.

PRISMA is positioned for the fit-check on its adapter hardware for the Vega launcher during activity at the Spaceport.

During activity in the Spaceport’s payload processing facilities, PRISMA (PRecursore IperSpettrale della Missione Applicativa) underwent its successful fit-check – a milestone in the preparation campaign that validated this spacecraft’s compatibility with the adapter that is to serve as the payload interface with Vega.

The mission with PRISMA is designated Flight VV14, signifying the 14th launch of the lightweight Vega vehicle – which joins Arianespace’s medium-lift Soyuz and heavyweight Ariane 5 in operations from French Guiana for a complete launcher family to orbit commercial, governmental, institutional, scientific and experimental payloads.

A wide range of applications for PRISMA

PRISMA – which will be operated by the Italian Space Agency (ASI) – was built by OHB Italia on a dedicated platform hosting the payload supplied by Leonardo Airborne and Space Systems. It is fitted with an innovative electro-optical instrument combining a hyperspectral sensor with a medium-resolution panchromatic camera.

This type of combined instrument offers the advantages of conventional observation (based on the recognition of geometric characteristics of a scene) coupled with the ability to determine the chemical and physical characteristics of the objects present in the scene, using the hyperspectral sensor.

The scientific community and other users will be able to employ these capabilities for a wide range of applications, including – but not limited to – environmental monitoring, resource management, identification and classification of crops, and the efforts to limit pollution.

Launch VV14 "mid-March",
Possibly a small launch delay due to the problems with Soyuz VS21.

It will most likely be between the 13th and the 15th.

PRISMA is currently in Kourou for launch campaign. Environmental tests have been successfully performed in Tolouse, completing system qualification.

Satellite launch is scheduled for 14 March 2019 22:50 local time (15 March 01.50 UTC).
