Pixel-level Terrain Processing of the Martian Surface from Moderate Resolution Images of Tianwen-1

The Astronomical Journal
The moderate-resolution camera (MoRIC) of the Tianwen-1 orbiter, China’s first Mars exploration mission, is a frame-imaging scheme color camera. However, generating a precise digital elevation model (DEM) from these images faces challenges due to the ...

Response of Martian Tail Lobes to Heliospheric Current Sheet: Tianwen-1 and MAVEN Joint Observations

The Astrophysical Journal Letters
Martian magnetotail lobes, mainly formed by the draped interplanetary magnetic field extending downstream in the tailward direction, are largely controlled by the solar wind and respond sensitively to variations in upstream drivers.

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.

Research on internal gravity waves in the Martian atmosphere based on Tianwen-1 and Mars Global Surveyor occultation data

Earth and Planetary Physics
Internal gravity waves (IGWs) are critical in driving Martian atmospheric motion and phenomena. This study investigates Martian IGWs by using high-resolution data from China’s Tianwen-1 mission and the National Aeronautics and Space Administration’s Mars
