    <description>VIRTIS on Venus Express is a hyperspectral imager that was adapted from a spare instrument originally designed for the Rosetta mission. It uses a scanning mirror and a refraction grating to disperse light from a narrow slit onto a detector array. The data collected by VIRTIS is structured in cubes containing one spectral dimension and two spatial dimensions, reflecting the sampling along the slit and the scanning mirror's movement.</description>
