In-flight Calibration of the Magnetometer on the Mars Orbiter of Tianwen-1

, 2023
Mars Orbiter Magnetometer (MOMAG) is one of seven science payloads onboard Tianwen-1's orbiter. Unlike most of the satellites, Tianwen-1's orbiter is not magnetically cleaned, and the boom where placed the magnetometer's sensors is not long enough. These

Statistical Analysis of Multiple Bow Shock Crossings at Mars

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We conduct a statistical analysis of multiple bow shock (BS) crossings at Mars. Data from the magnetometer (MAG) and Solar Wind Ion Analyzer (SWIA) onboard the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft from its first 2 years in orbit is used to identify flapping events.

Using Tianwen-1 Differential One-way Range Signals to Probe Corotating Interaction Regions: Case Studies

, 2023
The study reports the first detection of corotating interaction regions (CIRs) in the solar wind by the differential one-way range (DOR) signals transmitted by Tianwen-1. Differential phase delay is calculated for the DOR signals. Variations of the total

Phase Boundaries Among Three Hydrous Ferric Sulfates and Their Implications for Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Ferric sulfate minerals have been identified by orbital and landed missions at multiple locations on Mars and are the most common minerals in the Acid Mine Drainage (AMD) system on Earth. The occurrences and the speciation of ferric sulfates are very sensitive to variations in environmental conditions, such as temperature (T), relative ...

Hydrous Components of Dusty Surfaces Inferred From Zhurong In Situ Observations

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The ubiquitous hydration features observed by Zhurong rover provided new insights into Mars aqueous paleoenvironments. However, the impact of the Martian dust was not previously discussed. Here, we conduct a joint analysis of the Multispectral Camera and Short‐Wave Infrared data to constrain the surface composition. The results show that these
