PRISMA satellite from tonight is in orbit around the Earth: ACS contribution to the mission


PRISMA is an Italian Space Agency’s satellite demonstrator. National industries and many Small and Medium Enterprises (SME) contributed to its design, launch and data receipt.  Using the VEGA launcher, it took off from the European base of Kourou in French Guyana at 2.50 am GMT+1.

PRISMA will complete the current Italian Space Agency offer of Earth Observation space segment, now primarly based on the Synthetic Aperture Radar of COSMO-SkyMed constellation. Thanks to its hyperspectral innovative optical sensor, PRISMA is able to acquire images of Earth surface to see the chemical and physical composition and provide information for several applications.

PRISMA represents an excellence deriving from the scientific and industrial ability of Italy to work as a team. PRISMA was developed by a Temporary Joint Venture of companies, led by OHB Italia, responsible for the mission and management of the three main segments (ground, flight and launch) and Leonardo, which built the electro-optical hyperspectral instrumentation in addition to on-board equipment such as solar panels and power supply unit.

"Leonardo's technology is at the heart of this mission: our hyperspectral camera, the most advanced and most powerful in the world, will equip Italy with the ability to study the Planet like never before” - said Alessandro Profumo, Chief Executive Officer of Leonardo. “Our Fucino Space Centre will follow the LEOP and in-orbit tests to guarantee the scientific community access to valuable data for sustainable development. Leonardo puts forth its best efforts to face this major challenge, with the energy, skills and dedication of women and men strongly committed to technological innovation".

Angelantoni Test Technologies is proud to have contributed to this specific aspect of the mission, thanks to its TVC named "GALILEO Large Thermal Vacuum Chamber" installed at Leonardo's Florence premises, where environmental tests were carried out on the hyperspectral electro-optical instrumentation.

The TVC, equipped with independently themoregulated shroud,  thermal plate and decontamination plate, has a useful internal volume of about 17 m3 and a temperature range of -193/+150°C. The chamber reaches the High Vacuum performance of <10-6 mbar in 3 hours.
