The Dielectric Properties of Martian Regolith at the Tianwen‐1 Landing Site
Geophysical Research Letters, 2023 Mars' surface is characterized by a weathered layer of regolith and exposed rock exposures that are the results of long‐term geological processes. The Mars Rover Penetrating Radar (RoPeR) on board the Zhurong rover of China's first Mars mission (Tianwen ...

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.

Successful Endoscopic Sealing of Gastric Perforation With Tissue Adhesive Following Endoscopic Treatment for Gastric Fundal Variceal Bleeding: A Case Report. [PDF]
Clin Case RepABSTRACT Gastric perforation after endoscopic treatment of gastric fundal variceal bleeding is extremely rare. In carefully selected patients with early, small perforations and limited peritoneal contamination, endoscopic tissue adhesive injection combined with conservative management may provide a feasible nonsurgical rescue strategy.

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
