Characteristics of Dust Devils in Two Pre-Selected Landing Regions of the Tianwen-1 Mission—Comparing Observations and Predictions Using Numerical Model

open access: yesRemote Sensing, 2022
The spatial and temporal distribution of dust devils (DDs) in the two pre-selected landing regions (ZA and ZB) of the Tianwen-1 mission in southern Utopia Planitia have been investigated by using images from the Context Camera (CTX) of the Mars ...

Plasma Acceleration by Magnetic Tension Forces in the Martian Magnetotail: MAVEN Observations

open access: yesGeophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The Martian magnetotail is a dynamic region where several processes contribute to plasma acceleration. Here, we analyze ∼5 ${\sim} 5$ years of Mars Atmosphere and Volatile EvolutioN (MAVEN) data to evaluate the role of magnetic tension forces in driving plasma acceleration within current sheets in the tail. Based on magnetic field measurements,

Establishment of Safety Evaluation Factors for Dust Storms in the Landing Area Selection for Tianwen‐3 Mission

open access: yesEarth and Space Science
China's Tianwen‐3 mission is expected to be launched around 2028, making it the first Mars sample return mission. Dust storms occurring in all seasons on Mars can affect the accuracy and safety of the landing and takeoff phases of Mars sampling missions.

Direct Observations of Acceleration of Planetary Ions From Mars' Ionosphere Through Magnetic Reconnection When IMF Rotates

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Mars lacks an intrinsic global magnetic field but possesses crustal magnetic anomalies and an atmosphere. Mars' ionosphere, resulted from interactions between Mars' atmosphere and solar radiation, directly interacts with solar wind and interplanetary magnetic field (IMF). However, the mechanisms governing ion acceleration and escape from Mars'
