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 ...

Calibrating mars orbiter laser altimeter pulse widths at mars science laboratory candidate landing sites [PDF]

, 2014
Accurate estimates of surface roughness allow quantitative comparisons between planetary terrains. These comparisons enable us to improve our understanding of commonly occurring surface processes, and develop a more complete analysis of candidate landing

MAVEN Observations of the Interloop Magnetic Reconnections at Mars

The 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.

Atmospheric origins of perchlorate on Mars and in the Atacama [PDF]

, 2010
Times Cited: 22Isotopic studies indicate that natural perchlorate is produced on Earth in arid environments by the oxidation of chlorine species through pathways involving ozone or its photochemical products.

Variability of Bow Shock Location at Mars [PDF]

Journal 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.

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

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 ...

Immunological detection of small organic molecules in the presence of perchlorates: relevance to the life marker chip and life detection on Mars. [PDF]

, 2011
The proposed ExoMars mission, due to launch in 2018, aims to look for evidence of extant and extinct life in martian rocks and regolith. Previous attempts to detect organic molecules of biological or abiotic origin on Mars have been unsuccessful ...

Meteorological Changes Across Curiosity Rover’s Traverse Using REMS Measurements and Comparisons Between Measurements and MRAMS Model Results

Remote Sensing
The Curiosity rover, from NASA’s Mars Science Laboratory (MSL), has climbed nearly 740 m from its landing location at −4500.971 m in Gale Crater to a location reached on sol 3967 on the slopes of Mt. Sharp at −3765.27 m.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be
