Planetary Geology: Extraterrestrial Model of Geology
Planetary geology is an interdisciplinary subject that develops from astronomy and geology. This subject mainly studies the formation and evolution of solid celestial bodies in the Solar System such as planets, satellites, asteroids, comets, and ...

A New Method for Retrieving Electron Density Profiles from the MARSIS Ionograms
The Martian ionosphere was actively detected by Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) aboard the Mars Express. The detected echo signal of the MARSIS at an epoch is presented as a function of frequency and time delay to form

Simulations of Io Plasma Torus Around Jupiter: Predictions for Lenghu Observatory
Characterizing the temporal evolution of the three‐dimensional structure of the Io plasma torus is essential to understand the dynamics of the Jovian magnetosphere. Optical imaging is a powerful tool to uncover the global torus structure.
