CIVA (Comet Infrared and Visible Analyser) is an integrated set of imaging instruments,
designed to characterize the 360◦ panorama (CIVA-P) as seen from the Rosetta Lander Philae, and
to study surface and subsurface samples (CIVA-M). CIVA-P is a panoramic stereo camera, while
CIVA-M is an optical microscope coupled to a near infrared microscopic hyperspectral imager. CIVA
shares a common Imaging Main Electronics (IME) with ROLIS. CIVA-P will characterize the landing
site, with an angular sampling (IFOV) of 1.1 mrad: each pixel will image a 1mm size feature at the
distance of the landing legs, and a few metres at the local horizon. The panorama will be mapped by
6 identical miniaturized micro-cameras covering contiguous FOV, with their optical axis 60◦ apart.
Stereoscopic capability will be provided by an additional micro-camera, identical to and co-aligned
with one of the panoramic micro-camera, with its optical axis displaced by 10 cm. CIVA-M combines
two ultra-compact and miniaturised microscopes, one operating in the visible and one constituting
an IR hyperspectral imaging spectrometer: they will characterize, by non-destructive analyses, the
texture, the albedo, the molecular and the mineralogical composition of each of the samples provided
by the Sample Drill and Distribution (SD2) system. For the optical microscope, the spatial sampling
is 7μm; for the IR, the spectral range (1–4μm) and the spectral sampling (5 nm) have been chosen
to allow identification of most minerals, ices and organics, on each pixel, 40μm in size. After being
studied by CIVA, the sample could be analysed by a subsequent experiment (PTOLEMY and/or
COSAC). The processwould be repeated for each sample obtained at different depths and/or locations
