    Rosetta's VIRTIS: Visible and Infrared Thermal Imaging Spectrometer

    VIRTIS (Visible and Infrared Thermal Imaging Spectrometer) is an imaging spectrometer onboard the Rosetta spacecraft. It will map and study the nature of the solids and the temperature on the surface of the nucleus. VIRTIS also identifies comet gases, characterises the physical conditions of the coma and helps to identify the best landing sites.
