Brief communication: Lower-bound estimates for residence time of energy in the atmospheres of Venus, Mars and Titan [PDF]

open access: yesNonlinear 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.

Chosen problems of terraforming Mars [PDF]

open access: yesPrzegląd Komunikacyjny
: Consideration was given to creating an atmosphere on Mars that would enable people to stay on the surface of Mars without spacesuits. The source of matter for this atmosphere are bodies brought from the outer zones of the Solar System.

What Is the Radiation Impact of Extreme Solar Energetic Particle Events on Mars?

open access: yesSpace 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.

A new model describing Forbush Decreases at Mars: combining the heliospheric modulation and the atmospheric influence

open access: yesEarth 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

open access: yesGeophysical 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.

The Mars Topside Ionosphere Response to the X8.2 Solar Flare of 10 September 2017

open access: yesGeophysical Research Letters, 2018
On 10 September 2017, irradiance from a magnitude X8.2 solar flare impacted Mars while the Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiter was characterizing the Mars upper atmosphere.

Constraints on the Size and Composition of the Ancient Martian Atmosphere from Coupled CO2–N2–Ar Isotopic Evolution Models

open access: yesThe 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 ...

MAVEN Observations of the Interloop Magnetic Reconnections at Mars

open access: yesThe Astrophysical Journal, 2023
Magnetic reconnection between neighboring magnetic field loops, the so-called interloop reconnection, is a common process to drive flares in the solar atmosphere.

Variability of Bow Shock Location at Mars [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1999
Bow shock formation, in case the supersonic solar wind flow is hindered by the atmosphere of Mars, is investigated. The atoms newly ionized from the extensive neutral atmosphere of Mars are loaded to the solar wind.

Retrieval of CO Relative Column Abundance in the Martian Thermosphere From FUV Disk Observations by EMM EMUS

open access: yesGeophysical Research Letters, 2022
Carbon monoxide (CO) is a sensitive tracer of the thermal profile and winds in Mars' middle atmosphere and the chemistry that balances CO2 in the whole atmosphere of Mars.
