Experiment: SPICAM
MULTICHANNEL OPTICAL SPECTROMETER
SOUNDING OF THE ATMOSPHERE OF MARS
Main scientific objectives:
vertical profiles of ozone, water vapour, CO, aerosols and temperature in the middle and lower atmosphere;
diagnostic of the ionosphere by measuring of ions CO2+, CO+, and neutral species H and CO;
global distribution of water vapour and building of the density model of the atmosphere.
Experimental technique:
measuring spectra of sunlight passed through the Martian atmosphere at the limb of the planet;
measuring spectra of sunlight reflected from the surface and attenuated in the atmosphere of Mars;
measuring auroral spectra of the Martian atmosphere
Main parts of the instrument:
SPICAM-S - Solar part of the instrument is a two-channel spectrometer for the technique of Solar occultation. It is mounted on the body of the spacecraft:
UV and visible channe | l = 250-650 nм, l/Dl = 300; |
IR channel | l = 1,8-4,8 mm, l/Dl = 1000 |
SPICAM-E -a versatile spectrometer for the technique of stellar occultation and observations of the Martian atmosphere; it includes three spectral channels, and it is mounted on the PAIS platform :
UV channel | l = 110-300 nм, Dl = 3 A; |
Visible channel | l = 200-800 nм, Dl = 3 или 15 A; |
Near IR channel | l = 600-1100 nм, Dl = 3 or 0.58 A for
measuring H2O at 936 nм.
| Mass | 46 kg |
Cooperation:
Russia, France, Belgium.
