Mariner 6: ultraviolet spectrum of Mars upper atmosphere.
Emission features from ionized carbon dioxide and carbon monoxide were measured in the 1900- to 4300-angstrom spectral region. The Lyman alpha 1216-angstrom line of atomic hydrogen and the 1304-, 1356-, and 2972-angstrom lines of atomic oxygen were observed.
متن کاملMars: upper atmosphere.
The thermal structure of the upper atmosphere of Mars has been theoretically investigated. The exospheric temperature, for a pure CO(2) model atmosphere, lies between 400 degrees and 700 degrees K. The origin of the Martian atmosphere is discussed in the light of these results.
متن کاملPreliminary Results of the Mariner Iv Occultation Measurement of the Atmosphere of Mars
The Mariner IV Occultation Experiment (Ref. 2) has been carried out by investigators from the Jet Propulsion Laboratory, Stanford University, and CorneU University. Previous knowledge of such atmospheric properties as the surface pressure and density, as well as scale height, has been quite poorly defined. The surface pressure, as deduced from recent spectroscopic observations of weak and stron...
متن کاملMariner 9 ultraviolet spectrometer experiment: seasonal variation of ozone on Mars.
Ozone is observed to be present in the polar regions of Mars and to have a seasonal variation. In the summer, the amount present in the polar atmosphere is less than 3 micrometer-atmospheres. In the fall, ozone increases in amount and is found in association with the formation of the polar hood. In winter, the maximum amount of ozone is present, 57 micrometer-atmospheres over the polar hood and...
متن کاملMariner 9 Ultraviolet Spectrometer Experiment: Vertical Distribution of Ozone on Mars
The vertical distribution of ozone in the atmosphere of Mars is computed from ultraviolet spectra obtained by the Mariner 9 spacecraft. In the Northern Hemisphere the ozone scale height is much smaller than the atmospheric scale height in midlatitudes and increases rapidly to a maximum farther north. At high latitudes (above 60 °) there is no significant difference between the scale heights of ...
