Characterizing the current systems in the Martian ionosphere

When the solar wind encounters the ionosphere of an unmagnetized planet, it induces currents, forming an induced magnetosphere. These currents, along with their associated magnetic fields, play a crucial role in controlling the movement of charged particles, and are essential for understanding the escape of planetary ions.

Joint Observation of a Rotational Discontinuity by Tianwen‐1 and MAVEN at Mars

Geophysical Research Letters
The solar wind plays a crucial role in the evolution of planets in the solar system, particularly Mars. Mars has no global intrinsic magnetic field, leading the solar wind to interact directly with the Martian ionosphere and atmosphere.

MAVEN Observations of Metallic Fe 1 + Distributions in the Martian Ionosphere

Metallic ions deposited in planetary atmospheres via meteoroid ablation are an in valuable tool for understanding electric fields, atmospheric winds, and minor ion transport. At Mars, metallic ion distributions are poorly understood.

On the response of Martian Ionosphere to the Passage of a Corotating Interaction Region: MAVEN Observations

, 2019
The response of Martian ionosphere to the passage of corotating interaction region (CIR) of June 2015 is studied using observations from several instruments aboard the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission. An intense CIR arrived at Mars

Study on the Coupling between the Ionosphere and Thermosphere at Different Heights on Mars

The Astrophysical Journal
Solar-driven thermal tides are an important factor driving spatiotemporal variations in the Martian upper atmosphere and ionosphere. Based on radio occultation data from the Mars Global Surveyor, this study systematically investigates the longitudinal ...

Mars- Solar wind interaction: 3D GCM-Ionosphere model to describe the Martian ionospheric dynamics and its coupling with neutral atmosphere

, 2010
International audienceRecent observations and simulations showed the importance of the upper atmosphere/ionosphere in the escape processes at Mars. The solar wind interacts with the Martian ionosphere leading to an ionospheric outflow into the Martian ...

Convergent Heavy-ion Plume from the Martian Ionosphere

The Astrophysical Journal
Ion escape is a key consequence of the solar wind interaction with Mars, yet the three-dimensional structure of the heavy-ion plume, a major escape channel, remains poorly constrained.
