Transient Hydrology in Amazonis Planitia (Mars) in the Aftermath of the Tooting Impact

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract Hydrological flows generated by meteoroid impact are still largely unexplored on Mars and may also have implications for Earth. We reconstructed the hydrological sequence initiated on Mars by a less than 3 Ma old meteoroid impact that formed the 28 km‐wide Tooting crater on Amazonis Planitia, an ice‐bearing region.

Metasurface Effect on the Performance of Planar Antennas for Wireless Communications

open access: yesRadio Science, Volume 60, Issue 11, November 2025.
Abstract This paper demonstrates the performance enhancement of a conventional planar antenna by incorporating metasurface (MTS) layer using a proposed unit‐cell array. The impact of MTS unit‐cell density on bit‐error‐rate (BER) and channel capacity (CC) in a point‐to‐point microwave link is investigated.

Exploring the Validation Results of the Advanced Solar Particle Events Casting System (ASPECS)

open access: yesSpace Weather, Volume 23, Issue 11, November 2025.
Abstract Solar Energetic Particle (SEP) events can adversely affect space and ground‐based systems. Space weather effects associated with SEP events can impact communication and navigation systems, spacecraft electronics and operations, space power systems, crewed space missions, and commercial aircraft operations.

Cosmic Ray Counting Variability From Water‐Cherenkov Detectors as a Proxy of Stratospheric Conditions in Antarctica

open access: yesEarth and Space Science, Volume 12, Issue 11, November 2025.
Abstract This work examines atmospheric effects on cosmic ray counts observed by a Water‐Cherenkov detector at the Argentine Antarctic Marambio Station. We analyze the influence of ground‐level barometric pressure and geopotential height at various pressure levels on daily particle rates, finding the strongest association at 100 hPa, linked to ...

Robotic Arm Geomechanical Experiments and Analyses to Enable Lunar Science and Settlement

open access: yesEarth and Space Science, Volume 12, Issue 11, November 2025.
Abstract This study evaluates the capability of a robotic arm equipped with a force‐torque sensor and a specially designed scoop to perform geomechanical characterization of high‐fidelity lunar highlands regolith simulant. Experiments focused on pressure‐sinkage, shear strength, and angle of repose to assess the performance and applicability of the ...
