The Lunar Mare Ring-Moat Dome Structure (RMDS) Age Conundrum: Contemporaneous With Imbrian-Aged Host Lava Flows or Emplaced in the Copernican?

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (8)

Ring-moat dome structures (RMDSs) are small circular mounds of diameter typically about 200 m and similar to 3-4 m in height, surrounded by narrow, sh......

Global Distribution of Electrostatic Electron Cyclotron Harmonic Waves in Saturn's Magnetosphere: A Survey of Over-13-Year Cassini RPWS Observations

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (4)

Based on the measurements from Radio and Plasma Wave Science instrument onboard the Cassini spacecraft over 13 years, we perform a statistical analysi......

Evidence for the Disproportionation of Iron in a Eucrite Meteorite: Implications for Impact Processes on Vesta

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (8)

Pure metallic iron is a common component in extraterrestrial samples (e.g., ordinary chondrite, returned lunar samples), and is thought to be an indic......

The Composition of the South Polar Cap of Mars Derived From Orbital Data

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (8)

The flexure of the lithosphere under stresses imposed by the geologically young south polar cap is one of the few clues we have regarding the south po......

3-D Density Structure of the Lunar Mascon Basins Revealed by a High-Efficient Gravity Inversion of the GRAIL Data

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (5)

The lunar mascon basins are characterized by high gravity anomalies and thin crust. Study of the density structure beneath the mascon basins can help ......

Depth of Martian Magnetization From Localized Power Spectrum Analysis

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (8)

Magnetic field measurements show that Mars possesses strong crustal magnetic anomalies that formed when the planet had an active dynamo. To investigat......

Geologically Old but Freshly Exposed Rock Fragments Encountered by Yutu-2 Rover

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (3)

During the exploration traverse of the Von Karman crater on the lunar farside, the Yutu-2 rover, part of China's Chang'e-4 mission, come across rock f......

Natural Radiation Shielding on Mars Measured With the MSL/RAD Instrument

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (8)

Protecting astronauts from the effects of space radiation remains one major stepping stone for the exploration of Mars. Long-term exposure to radiatio......

Abnormal Phase Structure of Thermal Tides During Major Dust Storms on Mars: Implications for the Excitation Source of High-altitude Water Ice Clouds

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (4)

Interactions among the thermal tide, airborne dust, and water ice clouds significantly influence the Martian atmosphere. The absence of a stratosphere......

Possible Deep Structure and Composition of Venus With Respect to the Current Knowledge From Geodetic Data

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (7)

Almost no in situ seismic data are available for Venus; therefore, we can constrain the deep structure of this planet only from the geodetic data obta......

Possible Non-Mare Lithologies in the Regolith at the Chang'E-5 Landing Site: Evidence From Remote Sensing Data

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (5)

The Chang'E-5 (CE-5) mission returned a total of 1,731 g of lunar regolith from the northern Oceanus Procellarum (NOP). Despite that the CE-5 landing ......

Properties of Lunar Regolith on the Moon's Farside Unveiled by Chang'E-4 Lunar Penetrating Radar

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS, 2021; 126 (6)

The complex thermal history of the Moon leads to an unequal distribution of volcanic products between the lunar nearside and the farside. So far, no l......
