Mercury's Tidal Love Number h2 ${h}_{2}$ From Co‐Registration of MLA Profiles

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Due to its eccentric orbit, Mercury experiences a varying gravitational pull from the Sun along its orbit, leading to periodic surface tidal deformation. The previous measurement of Mercury's tidal h2 ${h}_{2}$ by Bertone et al. (2021, https://doi.org/10.1029/2020je006683) is based on minimizing height differences at cross‐overs of the Mercury

Surface Waves along the Martian Ionopause

Acta Physica Polonica A, 2013
We study the behaviour of surface waves propagating along the ionopause of the planet Mars and derive the onset criteria for unstable Kelvin Helmholtz modes and negative energy waves at the Martian ionopause. Growth rate of unstable Kelvin Helmholtz mode decreases with wavelength.

Gravity and Magnetic Field Signatures in Hydrothermally Affected Regions on Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Multiple lines of evidence indicate that liquid water‐rock interactions occurred on ancient Mars, particularly within the crust, where hydrothermal systems have been hypothesized. Such hydrothermal circulation (HC) can significantly lower temperatures in the crust, thereby restricting the viscoelastic relaxation of impact craters. Craters with

Modeling Lake Bonneville Paleoshoreline Erosion at Mars‐Like Rates and Durations: Implications for the Preservation of Erosional Martian Shorelines and Viability as Evidence for a Martian Ocean

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Mars may have had an ancient ocean filling its northern lowlands until around 3.5 billion years ago. The existence or lack of such a large body of water would have important implications on the ancient martian climate, landscapes, and habitability.

Field Measurements of Terrestrial and Martian Dust Devils [PDF]

, 2016
Surface-based measurements of terrestrial and martian dust devils/convective vortices provided from mobile and stationary platforms are discussed. Imaging of terrestrial dust devils has quantified their rotational and vertical wind speeds, translation ...

Different Faces of the Martian Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract The Martian magnetosphere contains components of the induced and intrinsic magnetospheres. Since we can not get a global snapshot of the magnetosphere we use a statistical picture based on a large number of measurements. Depending on the choice of coordinate system and the data selection we can observe different faces of the Martian ...

Hubble Space Telescope observations of Mars [PDF]

Hubble Space Telescope (HST) afforded the possibility of resolving features as small as 100 km on the Martian surface even when it is at the far point of its orbit. Therefore it is ideally suited for monitoring seasonal changes on the red planet.

A review of volatiles in the Martian interior [PDF]

, 2016
Multiple observations from missions to Mars have revealed compelling evidence for a volatile-rich Martian crust. A leading theory contends that eruption of basaltic magmas was the ultimate mechanism of transfer of volatiles from the mantle toward the ...

Nowcasting Solar Energetic Particle Events for Mars Missions

Space Weather, Volume 23, Issue 4, April 2025.
Abstract In addition to the omnipresent Galactic Cosmic Rays, sudden Solar Energetic Particle (SEP) events present considerable health hazards for manned space missions. These events not only contribute to an increased long‐term cancer risk, but can, in extreme cases, cause acute radiation syndromes.
