Abstract
Atmospheric Remote-Sensing Infrared Exoplanet Large-survey (Ariel) is a visible/infrared mission funded by the European Space Agency. It will be launched in 2029 and will aim to observe a target of ∼1000 exoplanets to study their atmospheres in chemical composition and ephemeris. Ariel will be the first space mission designed specifically for this purpose. The intervention aims to give an overview of the space project; in particular, the Italian contribution to the realization of the telescope will be emphasized. The telescope will be an off-axis Cassegrain with an elliptical-shaped parabolic primary mirror of considerable size (1.1 × 0.7m optical area) entirely made of bare aluminum. Today, an aluminum mirror of this size (mainly for its major axis) has never been created for infrared observations. For this reason, the Italian team, supported by the industry, has planned a development, qualification, and validation campaign for a series of manufacturing processes for these optics. In particular, it will illustrate how the development of heat treatment, diamond turning, polishing, and coating were addressed to obtain large-sized polished aluminum optics.
