ULTRAVIOLET SPECTROPHOTOMETER

MEASUREMENTS OF THE CHEMICAL COMPOSITION OF THE UPPER ATMOSPHERE



Main scientific objectives:

  • hydrogen, helium, and oxygen distribution in the upper atmosphere of Mars;
  • deuterium abundance in the Martian atmosphere;
  • high-altitude temperature profile of the atmosphere;
  • neutral component of the interstellar-interplanetary medium.

    Photometer measures the intensity in lines:
  • HI 1215,7 A (neutral atomic hydrogen);
  • DI 1215,3 A (neutral atomic deuterium);
  • HeI 584 A (neutral atomic helium);
  • OI 1304 A (neutral atomic oxygen);
  • OII 834 A (singly-ionized atomic oxygen).


  • Main characteristics:
    power consumption 15 W
    date rate 68,5bit/s
    mass9,5kg


    Instrument operates along the Earth-to-Mars trajectory and on the orbit of Mars in the mode of periodic switch-on.




    Cooperation: Russia,Germany, France.
