Geological characteristics of Chang’E-6 landing area in micro-scale unveiled by new observation data

Nature Communications
Chang’E-6 mission successfully achieved humanity’s first sample return from the farside of the Moon. Here, we report a high-precision terrain dataset with millimeter-to-decimeter spatial resolution around the CE-6 landing site. Based on this dataset, the

Static effects of differential rotation on Jupiter’s shape, gravity field, and interior structure

Astronomy & Astrophysics
Context. Jupiter’s atmosphere has strong zonal flows and exhibits marked differential rotation. The dynamic effects of these flows on Jupiter’s gravity field and internal structure have been extensively investigated in order to interpret Juno gravity ...

Energy Conversion Associated with Intermittent Currents in the Magnetosheath Downstream of the Quasi-Parallel Shock

Magnetochemistry
Using the data from the Magnetospheric Multiscale (MMS) mission, we studied the energy conversion between electromagnetic fields and particles (ions and electrons) in a spacecraft rest frame inside a turbulent magnetosheath downstream of the quasi ...

Seismic visibility of carbonated subducted oceanic crust in the lower mantle

Communications Earth & Environment
Seismological studies have previously detected abundant scatterers in the lower mantle, potentially linked to long-term slab subduction, and petrology studies suggest carbonates can be sequestrated within the oceanic crust and transported into the lower ...

Ion and electron motions in the outer electron diffusion region of collisionless magnetic reconnection

Earth and Planetary Physics
Two-dimensional particle-in-cell simulations are performed to study the coupling between ion and electron motions in collisionless magnetic reconnection. The electron diffusion region (EDR), where the electron motions are demagnetized, is found to have a

An embedded electron current layer observed at the edge of the plasma sheet in the Earth’s magnetotail

Earth and Planetary Physics
The formation of an embedded electron current sheet within the magnetotail plasma sheet has been poorly understood. In this article, we present an electron current layer detected at the edge of the magnetotail plasma sheet.

Numerical Simulations of the Lunar Penetrating Radar and Investigations of the Geological Structures of the Lunar Regolith Layer at the Chang’E 3 Landing Site

International Journal of Antennas and Propagation, 2017
In the process of lunar exploration, and specifically when studying lunar surface structure and thickness, the established lunar regolith model is usually a uniform and ideal structural model, which is not well-suited to describe the real structure of ...
