Towards a global model of the martian atmosphere [PDF]
, 2003 In an effort to continuously improve the capabilities of the Martian atmospheric predictions at LMD, the GCM has been extended into thermospheric heights thus creating the first model to self-consistently couple the lower and upper regions of the ...

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.Abstract Mars may have had an ancient ocean filling its northern lowlands until around 3.5 billion years ago. The existence or lack of such a large body of water would have important implications on the ancient martian climate, landscapes, and habitability.

Wind measurements in Mars' middle atmosphere at equinox and solstice: IRAM Plateau de Bure interferometric CO observations [PDF]

Lewis, E. Millour, P.L. Read and R.J. Wilson. Publisher : LMD, IAA, AOPP,
CNES, ESA, 2006., p.134, Espagne (2006), 2007 Characterizing the Martian atmosphere is an essential objective to understand its meteorology and its climate. The lower atmosphere (< 40 km) and middle atmosphere (40-80 km) of Mars appear dynamically coupled at much higher levels than in the case of the Earth.

Non-tidal Coupling of the Orbital and Rotational Motions of Extended Bodies [PDF]
arXiv, 2020 The orbital motions and spin-axis rotations of extended bodies are traditionally considered to be coupled only by tidal mechanisms. The orbit-spin coupling hypothesis supplies an additional mechanism. A reversing torque on rotating extended bodies is identified.

Different Faces of the Martian Magnetosphere
Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.Abstract The Martian magnetosphere contains components of the induced and intrinsic magnetospheres. Since we can not get a global snapshot of the magnetosphere we use a statistical picture based on a large number of measurements. Depending on the choice of coordinate system and the data selection we can observe different faces of the Martian ...

An estimation of the mass dragged by the solar wind from Mars’s atmosphere in its geologic history [PDF]
Geofísica Internacional, 2001 In the past Mars had a denser atmosphere, but it lacks a magnetic field to protect the ionosphere and exosphere from the solar wind. A model for describing the loss of atmosphere in geologic time is presented.

Hubble Space Telescope observations of Mars [PDF]
Hubble Space Telescope (HST) afforded the possibility of resolving features as small as 100 km on the Martian surface even when it is at the far point of its orbit. Therefore it is ideally suited for monitoring seasonal changes on the red planet.

Nowcasting Solar Energetic Particle Events for Mars Missions
Space Weather, Volume 23, Issue 4, April 2025.Abstract In addition to the omnipresent Galactic Cosmic Rays, sudden Solar Energetic Particle (SEP) events present considerable health hazards for manned space missions. These events not only contribute to an increased long‐term cancer risk, but can, in extreme cases, cause acute radiation syndromes.

Assessment of the probability of microbial contamination for sample return from Martian moons I: Departure of microbes from Martian surface [PDF]
arXiv, 2019 Potential microbial contamination of Martian moons, Phobos and Deimos, which can be brought about by transportation of Mars ejecta produced by meteoroid impacts on the Martian surface, has been comprehensively assessed in a statistical approach, based on the most probable history of recent major gigantic meteoroid collisions on the Martian surface ...
