  1. Measurement of the solar spectrum in the Martian surface and its variation along the day and seasons.
  2. Estimation of the atmospheric optical depth (comparison with previous missions).
  4. Observation of Phobos transits: calculation of the exact landing site.
  5. Characterization by means of a rotation model, of the moment of inertia of the nucleus.
