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 ...

Formation of Tianwen-1 landing crater and mechanical properties of Martian soil near the landing site

International Journal of Mining Science and Technology
After landing in the Utopia Planitia, Tianwen-1 formed the deepest landing crater on Mars, approximately 40 cm deep, exposing precious information about the mechanical properties of Martian soil.

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.

MarsQE: Semantic-Informed Quality Enhancement for Compressed Martian Image

Lossy image compression is essential for Mars exploration missions, due to the limited bandwidth between Earth and Mars. However, the compression may introduce visual artifacts that complicate the geological analysis of the Martian surface.
