SUPERCAM is a suite of 5 instruments

Raman / Fluorescence Spectroscopy: Provides Raman and time-resolved fluorescence spectra up to 12 m for most minerals, much farther for Raman-bright materials, giving clear remote organic detection and mineral identification.

Laser-Induced Breakdown Spectroscopy: Gives elemental composition and depth profiles up to 7 m distance as sub-millimeter scale, as performed successfully on ChemCam. LIBS also clears dust for the other investigations.

Visible and Infrared Spectroscopy: Combines ChemCam's VNIR (400-900 nm) and NIR 1.3-2.6 µm reflectance spectroscopy, providing clear mineral detection up to 10 km; includes rapid scan mode.

Color Remote Micro-Imaging (RMI): Offers fine-scale remote imaging to infinity, providing texture and morphological context for the chemical, biological and mineral measurements, in color.

Microphone: Records the impacts of the LIBS up to 4 m.

The operating sequences are foreseen as follows:

  • first laser shot to clear the dust for other investigations
  • then Raman and passive IR spectroscopy
  • colour images for the context

The remote distance capacity of SuperCam depends on the instruments:
