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.

Visual Localization and Topographic Mapping for Zhurong Rover in Tianwen-1 Mars Mission

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This article presents the methods, results, and applications of visual localization and topographic mapping for the Zhurong rover in China's Tianwen-1 Mars mission. New techniques, namely vignette correction and online camera mast calibration, were developed for the images captured by the rover's navigation and terrain cameras (NaTeCam) to enhance the ...
