Isotopic Composition of the Martian Atmosphere
Science, 1976Results from the neutral mass spectrometer carried on the aeroshell of Viking 1 show evidence for NO in the upper atmosphere of Mars and indicate that the isotopic composition of carbon and oxygen is similar to that of Earth. Mars is enriched in 15 N relative to Earth by about 75 percent, a consequence of escape ...

Jupiter's Atmosphere: Its Structure and Composition
Science, 1967Recent laboratory and observational data support the hypothesis that the composition of Jupiter's atmosphere is consistent with the relative abundances of the elements found in the sun. A model based on this assumption provides a reasonable interpretation of abundances of hydrogen and other gases obtained from studies of various regions of the planet's

Titan's atmosphere composition: Certainties and speculations
Advances in Space Research, 1995Firm results concerning the thermal structure, the composition, the seasonal effects of the atmosphere of Titan, as well as the superotation of its stratosphere are reviewed. The nature of the surface of the satellite, the possible presence of argon in the atmosphere and the structure and composition of clouds and aerosols are, among other topics ...
