Microwave spectroscopy of the Mars atmosphere [PDF]
Applied Optics, 1995 A study of the use of millimeter-wavelength spectral transitions to investigate the atmosphere of Mars is presented. In the model experiments investigated it is assumed that a spectrometer in the frequency range from 100 to 260 GHz looks into a modest-sized telescope of from 30 to 50 cm aperture from a near-Mars orbit.

Study on Effect of Aerodynamic Configuration on Aerodynamic Performance of Mars Ascent Vehicles
Space: Science & Technology, 2022 The Mars surface take-off and ascent technology is one of the key technologies for realizing the Mars sample return mission. Different from that on the moon, the gravity acceleration on the surface of Mars is 3.71 m/s2, so that the gravity loss is larger

A three-dimensional atmospheric dispersion model for Mars
Progress in Earth and Planetary Science, 2021 Atmospheric local-to-regional dispersion models are widely used on Earth to predict and study the effects of chemical species emitted into the atmosphere and to contextualize sparse data acquired at particular locations and/or times. However, to date, no

Detection of Martian dust storms using mask regional convolutional neural networks
Progress in Earth and Planetary Science, 2022 Martian dust plays a crucial role in the meteorology and climate of the Martian atmosphere. It heats the atmosphere, enhances the atmospheric general circulation, and affects spacecraft instruments and operations.

Optimal Technology Allocation of in the Life Support Subsystem with Maximum Reliability [PDF]
فناوری در مهندسی هوافضا, 2023 The atmosphere of the Red Planet or Mars contains 95% of carbon dioxide, 3% of nitrogen, 1.6% of argon and only a small amount of oxygen, and in terms of concentration is about one percent of the planet's atmosphere, which makes it virtually impossible ...

Brief communication: Lower-bound estimates for residence time of energy in the atmospheres of Venus, Mars and Titan [PDF]
Nonlinear Processes in Geophysics, 2021 The residence time of energy in a planetary atmosphere, τ, which was recently introduced and computed for the Earth's atmosphere (Osácar et al., 2020), is here extended to the atmospheres of Venus, Mars and Titan.

Influence of Magnetic Fields on Precipitating Solar Wind Hydrogen at Mars
Geophysical Research Letters, 2022 Solar wind protons can interact directly with the hydrogen corona of Mars through charge exchange, resulting in energetic neutral atoms (ENAs) able to penetrate deep into the upper atmosphere of Mars.
