Abstract Current Mars thermospheric temperatures databases have course temporal resolution due to either a lack of data or a need to average over several orbits of data, preventing the study of short‐term, rapid changes to the Mars thermosphere. In this study, we present a new Mars thermosphere temperature database derived from individual orbits of ...

Abstract The May 2024 G5 geomagnetic storm produced significant disturbances in the ionosphere and thermosphere, particularly at high latitudes. Using high‐resolution in situ ion and neutral density measurements from the NASA Low‐Latitude Ionosphere/Thermosphere Enhancements in Density (LLITED) CubeSat at 430 km altitude, this study documents notable ...

Abstract Recent studies have demonstrated that warm coronal emissions during the extreme ultraviolet late phase (ELP) of X‐class solar flares can be sufficiently strong to also affect electron density in the Earth's ionosphere. The Fe XV 28.4 nm line was identified as one of the most geoeffective emissions produced during the ELP.

LIBS Elemental Mapping of a Feldspathic Lunar Meteorite: Insights for In Situ Exploration
Abstract To meet the objectives of the many robotic and human missions planned for the Moon in the coming decade, new scientific instruments are currently under development. Laser‐induced breakdown spectroscopy (LIBS) is a robust technique for quantifying elemental abundances by focusing a pulsed laser to generate a plasma and collecting its emission ...

Abstract Lunar magnetic anomalies are abundant near the south pole, where several moderate‐strength anomalies spatially overlap permanently shadowed regions (PSRs). This environment provides a unique setting to assess how crustal magnetic fields and topography regulate plasma–surface interactions and, in turn, the stability and distribution of surface ...

Abstract In this study, we employ a deep learning approach to detect auroras from near‐infrared (NIR) sequential images captured by the satellite‐based imager, the Enhanced Polar Outflow Probe (e‐POP)/Fast Auroral Imager (FAI). We also apply the Eigen‐Class Activation Map (Eigen‐CAM), an explainable AI technique in a broad sense, as a post‐hoc ...

Abstract For decades, two competing hypotheses on the key drivers of mid‐latitude long‐duration positive ionospheric storms (LDPS) have been considered: (a) an increase of the F2‐layer peak height (hmF2) and (b) an increase in the atomic oxygen to molecular nitrogen density ratio (O/N2).

Performance Investigation of Four Ionospheric Models in Estimating hmF2 in High‐Latitude Regions
Abstract As a critical parameter characterizing the vertical structure of the ionosphere, the peak height of the F2 layer (hmF2) plays an essential role in frequency selection and signal propagation in high‐frequency (HF) communication systems. Accurate prediction of hmF2 is particularly important in high‐latitude regions.
