It is believed that Mars underwent drastic climate change, changing its environment from warm and wet to cold and dry. This gives rise to the idea that Mars may have hosted life in the past and, indeed, may do so even today. Atmospheric evolution is thus an important key to understanding the history of Martian habitability.

Measurements in the Atmosphere of Mars
Applied Optics, 1969The detailed definition of the key features of Mars' atmosphere from one or a few entries and landings is a challenging task involving a variety of measurements, taken during entry and after landing, and correlated with observations to be taken from orbiters and flyby missions.

The main emphasis of this review will be on Martian aeronomy, here defined to be the interaction of solar UV radiation with the atmosphere of Mars. A general outline of contemporary knowledge of the chemical composition and of the thermal structure of the Martian atmosphere, necessary for aeronomical calculations, is given in Sections 2 and 3 ...

Nightglow in the Upper Atmosphere of Mars and Implications for Atmospheric Transport
Science, 2005We detected light emissions in the nightside martian atmosphere with the SPICAM (spectroscopy for the investigation of the characteristics of the atmosphere of Mars) ultraviolet (UV) spectrometer on board the Mars Express. The UV spectrum of this nightglow is composed of hydrogen Lyman α emission (121.6 nanometers) and the γ and δ bands of

Abstracts of the Papers Printed in the Philosophical Transactions of the Royal Society of London
The author refers the origin of the hypothesis of the “Extensive Atmosphere of Mars” to the observations of Cassini and Rœner, made at Briare and Paris in the year 1672. By the former it would seem that a star of the fifth magnitude became invisible with a three-feet telescope when at a distance of six minutes from the planet whilst by the latter the ...

The Atmosphere of Mars: Detection of Krypton and Xenon
Science, 1976Krypton and xenon have been discovered in the martian atmosphere with the mass spectrometer on the second Viking lander. Krypton is more abundant than xenon. The relative abundances of the krypton isotopes appear normal, but the ratio of xenon-129 to xenon-132 is enhanced on Mars relative to the terrestrial value for this ratio.

The Atmosphere and Climate of Mars
2017Humanity has long been fascinated by the planet Mars. Was its climate ever conducive to life? What is the atmosphere like today and why did it change so dramatically over time? Eleven spacecraft have successfully flown to Mars since the Viking mission of the 1970s and early 1980s.

The atmosphere and haze of Mars
Journal of Geophysical Research, 1960The 'blue haze' is an absorbing smoke, dark as soot in reflection, red in transmission. Its currently accepted explanation by pure scattering (omnidirectional or forward) is untenable, as it would either increase the surface brightness of fall to obscure the surface details.

Oblateness of the atmosphere of Mars
Nature, 1976ON April 8, 1976 Mars occulted the bright star ɛ Geminorum (magnitude 3.2). Predictions1 were issued well in advance since such occurrences are very rare: indeed, it is estimated that Mars occults a star as bright as this about once in 500 yr. Accurate observations of the duration of the occultation were made from four sites on the Earth and these are ...
