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.

Enhancing Mars Gravity Field Solutions with China’s Tianwen-1 Tracking Data

The Astrophysical Journal
Abstract The Tianwen-1 (TW1) mission, which successfully entered Mars's orbit in 2021, provides a valuable data set for enhancing the understanding of Mars’s gravity field. The highly elliptical near-polar orbit of the TW1 orbiter offers unique sensitivity to long-wavelength gravity signals, complementing the contributions of low ...
