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.

What Is the Radiation Impact of Extreme Solar Energetic Particle Events on Mars?
Space Weather, 2023 Solar Energetic Particles (SEP) are one of the major sources of the Martian radiation environment. It is important to understand the SEP‐induced Martian radiation environment for future human habitats on Mars.

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 ...

Earth and Planetary Physics, 2020 Forbush decreases are depressions in the galactic cosmic rays (GCRs) that are caused primarily by modulations of interplanetary coronal mass ejections (ICMEs) but also occasionally by stream/corotating interaction regions (SIRs/CIRs).

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.

Long-term variability of CO2 and O in the Mars upper atmosphere from MRO radio science data [PDF]
, 2015 We estimate the annual variability of CO2 and O partial density using approximately 6years of Mars Reconnaissance Orbiter (MRO) radio science data from August 2006 to January 2012, which cover three full Martian years (from the northern hemisphere summer

The Atmospheres of Mars and Venus [PDF]
Annual Review of Astronomy and Astrophysics, 1961 Of all the planets which may exist in the Universe, only nine have been studied by man. As a result, one cannot classify planets with the same confidence that one has in classifying stars; there is no theory of planetary evolution comparable in development to the theory of stellar evolution.

The Planetary Science Journal, 2023 Present-day Mars is cold and dry, but mineralogical and morphological evidence shows that liquid water existed on the surface of ancient Mars. In order to explain this evidence and assess ancient Mars’s habitability, one must understand the size and ...
