The Italian Space Agency (ASI) is funding 3 scientific instruments of Solar Orbiter.

Metis — Metis is the Italian instrument onboard Solar Orbiter. This instrument is a coronagraph which monitors the outer solar corona and the coronal mass ejection activity.
Italian industry is responsible for the instrument development and delivery to ASI and ESA. International hardware contributions from the Cetzch Republic and Germany.
Principal Investigator: Marco Romoli

SWA — ASI contributes the Data Processing Unit of the Solar Wind Analyzer of the Solar Orbiter, a key in situ instrument of Solar Orbiter which measures the solar wind properties.
Italian Co-Principal Investigator: Roberto Bruno

STIX — ASI supports the Italian contribution to the software development for STIX, the instrument which detects the X-ray emission of solar flares.
The Italian contribution to the STIX investigation is concerned with the development of computational methods for imaging and imaging spectroscopy. Anna Maria Massone (CNR - SPIN, Genova) and Michele Piana (Dipartimento di Matematica, Università di Genova) are both co‑Investigators of the mission and coordinate the activity of the Italian group on the development of Fourier-based techniques for the reconstruction of hard X‑ray and mean electron flux images at different photon and electron energies. Sara Giordano is a PhD student at the Dipartimento di Matematica, Università di Genova, working at the implementation of these techniques and at their application to synthetic STIX visibilities.
Italian responsible for the Data Analysis Software: Michele Piana
