HIGH-RESOLUTION MAPPING SPECTROMETER

STUDY OF THE MARTIAN SURFACE COMPOSITION AND ITS PHYSICAL PROPERTIES



Main scientific objectives:

  • spectrophotometry of the planet in absorption bands of some rocks that may exist on the Martian surface in order to determine the surface composition;
  • study of the nature of aerosols by measuring spectral and angular distributions off brightness both above the planetary limb and of certain cloud-covered areas;
  • TERMOSCAN data conversion into digital form compatible with that of the MORION system .

    Instrument has 14 spectral subbands in the 260-900 nm ( a detector: PMT) and 6 subbands in the near-infrared. The spectrophotometer maps the surface in 32 lines with the mean resolution ( about 0,3 km at the pericenter), and 1 low-resolution IR line ( 3km). The instrument has a turnable entrance mirror permitting observations of different areas of the planet. The observation tracks will pass over the planet surface approximately in meridional direction. Taking into account the variable along-track resolution, about 50 percent of the Martian surface can be mapped during one-year observations from the Martian orbit.

    Main characteristics:
    Spectral range 260-900 nm and
    0,95 - 2,6 m
    Main detector PMT 32 pixels
    Main field of view32 ћ ( 10 'ћ10' )
