Analysis, Testing, and Design of a UHF and HF Peer‐to‐Peer Communication System for the Europan Cryosphere

open access: yesEarth and Space Science, Volume 12, Issue 8, August 2025.
Abstract This study presents a validated design of a dual‐band wireless relay system of “pucks” for through‐ice communication between a cryobot and a surface lander during a future exploration of the Europan cryosphere. The design of a terrestrial demonstration system and the results of a 103 m through‐ice system test in a relevant environment near ...

Fast and Invertible Simplicial Approximation of Magnetic‐Following Interpolation for Visualizing Fusion Plasma Simulation Data

open access: yesComputer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract We introduce a fast and invertible approximation for fusion plasma simulation data represented as 2D planar meshes with connectivities approximating magnetic field lines along the toroidal dimension in deformed 3D toroidal spaces. Scientific variables (e.g., density and temperature) in these fusion data are interpolated following a complex ...

Analysis of Solar Radiation Shielding in Space for Climate Mitigations of the Earth

open access: yesEnergy Science &Engineering, Volume 13, Issue 4, Page 1653-1661, April 2025.
Space solar shielding over the Earth. ABSTRACT Solar radiation modification (SRM) through space solar shielding is a proposed strategy to mitigate global warming. This approach involves reflecting sunlight back into space while allowing Earth's infrared radiation to escape, thereby controlling climate change.
