Raman, MIR, VNIR, and LIBS Spectra of Szomolnokite, Rozenite, and Melanterite: Martian Implications
Different sulfates (Ca-, Mg, and Fe- sulfates) have been extensively detected on the Martian surface. As one of the Martian sulfates, the presence of ferrous sulfates will provide valuable clues about the redox environment, hydrological processes, and ...

Numerical Evaluation of Planetary Radar Backscatter Models for Self-Affine Fractal Surfaces
Numerous analytical radar-scattering laws have been published through the past decades to interpret planetary radar observations, such as Hagfors’ law, which has been commonly used for the Moon, and the cosine law, which is commonly used in the shape ...

A Microphysics Model of Multicomponent Venus' Clouds With a High‐Accuracy Condensation Scheme
Accurate modeling of the Venusian cloud structure remains challenging due to its complex microphysical properties. Condensation primarily determines the cloud particle size distribution within the various cloud layers.

Jupiter wind as a unifying bridge: a testable paradigm in the Tianwen-4 era
Jupiter's rotating magnetic field, together with its satellites and rings, generate a composite flow that we term the Jupiter wind in this paper: a multi-source mixture of particles originating from Io's volcanism, Jupiter’s other moons, its rings, and ...

Charged Clouds of Ionized Gas Emerge from Tribocharging Grains
If two solid particles collide, charge is exchanged. However, this transfer is not restricted to the surface of the particle. Ions are also dispersed into the environment. They form a charge cloud around the particle.

Temperatures of Jupiter’s Upper Atmosphere: The Role of the Planetary Magnetic Field
The primary source of heating in the upper atmospheres (thermospheres) of giant planets has been the subject of long debate. The conundrum (or “energy crisis”) consists in observed thermosphere temperatures at low and midlatitudes exceeding values ...

Effects of the 2007 Martian Global Dust Storm on Boundary Positions in the Induced Magnetosphere
Mars's magnetosphere is a sensitive system, varying due to external and internal factors, such as solar wind conditions and crustal magnetic fields.
