Experiment: UVS-M
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:
