C+ 133.5 nm Emission Mechanisms on Mars Revealed by the MAVEN Observations

The Astrophysical Journal
C ^+ emission is generated by electron impact, dissociative ionization, photoionization, and resonant scattering with carbon-related atoms, molecules, and ions in the Martian ionosphere and thermosphere. The contribution of each mechanism to the emission,

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.

Upstream IMF Influence on Closed Magnetic Field Orientation on Mars

Geophysical Research Letters
Closed magnetic fields play an important role in plasma transport and atmospheric escape from the Martian dayside ionosphere. Leveraging in‐situ magnetic field data from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, we conduct a statistical

Sporadic E-like Topside Layer Driven by Wind Shear in the Martian Ionosphere

The Astrophysical Journal
Ionospheric plasma density disturbances significantly affect radio wave propagation, impacting communication and planetary exploration. At Earth, sporadic E layers (Es) are commonly observed. They are characterized by thin, high-density plasma structures

Atmospheric Distribution and Escape of Odd Nitrogen on Mars

The Astronomical Journal
The total nitrogen budget in the Martian upper atmosphere is significantly contributed by the presence of odd nitrogen, mainly in the form of NO and ground-state or excited-state N.
