The invention relates to a Mars atmosphere three-dimensional density obtaining method based on data fitting and belongs to the technical field of deep space exploration. In the perpendicular direction, a layered index model is adopted, the atmosphere is divided into k layers, and the atmosphere ...
Absorption of interplanetary Lyman-α emission by Mars' nightside lower thermosphere was observed by Mars Express Spectrometer for Investigation of Characteristics of the Atmosphere of Mars (SPICAM), and is analyzed to derive the CO 2 density at 110 km during a martian year. The observed density ...

It is interesting that Mars’ atmosphere is very tenuous, even at the surface, and also exhibits large daily variations in wind speed from day to night (Chamberlain and Hunten, 1987). Thermospheric wind speeds for earth easily reach 30% of the speed of sound on a daily basis whereas, at...
Electrostatic precipitator dust density measurements in a Mars-like atmosphereMars atmospheric in-situ resource utilization processes will require dust filtration of large gaseous volumes. An electrostatic precipitator capable of operating in the Martian environment is under development to meet this need. We...

's atmosphere, but rather that of Mars, revealing that the little rock was in fact a meteorite from the red planet. It was dubbed the Lafayette Meteorite as a nod to the town in Indiana where Purdue University is based, and to this day, it continues to transform our knowledge of Mars....
Solar activity variations of thermospheric temperatures on Mars and a problem of CO in the lower atmosphere for the varying heliocentric distance are mostly due to the density variations in the lower and middle atmosphere and weakly affect thermospheric temperature...
