Joint Observation of a Rotational Discontinuity by Tianwen‐1 and MAVEN at Mars
Geophysical Research LettersThe 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.

Adaptive entry guidance for the Tianwen-1 mission [PDF]
Astrodynamics, 2022 AbstractTo meet the requirements of the Tianwen-1 mission, adaptive entry guidance for entry vehicles, with low lift-to-drag ratios, limited control authority, and large initial state bias, was presented. Typically, the entry guidance law is divided into four distinct phases: trim angle-of-attack phase, range control phase, heading alignment phase, and

The Analysis of Cones within the Tianwen-1 Landing Area
Remote Sensing, 2022 On 15 May 2021, the Zhurong rover of China’s first Mars mission, Tianwen-1 (TW-1), successfully landed in southern Utopia Planitia on Mars. Various landforms were present in the landing area, and this area recorded a complex geological history. Cones are one of the typical landforms in the landing area and Utopia Planitia, and they have a great ...
