Space Weather, Volume 24, Issue 7, July 2026.Abstract F10.7, Mg II, and F30 are widely used proxies for variability in solar Extreme UltraViolet (EUV, 5–120 nm) irradiance. An alternative proxy for solar EUV variability is QEUV, an indirect measure of total solar EUV irradiance, retrieved from observations of Earth's Far UltraViolet (FUV, 120–300 nm) airglow and from empirically modeled solar EUV

Earth and Space Science, Volume 13, Issue 7, July 2026.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 ...

Thermal structure and dynamics of the Martian upper atmosphere at solar minimum from global circulation model simulations [PDF]
Annales Geophysicae, 2007 Simulations of the Martian upper atmosphere have been produced from a self-consistent three-dimensional numerical model of the Martian thermosphere and ionosphere, called MarTIM.

Crosstalk in O2+ and CO2+ Channel Groups of MAVEN/NGIMS Ion Measurements
Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.Abstract The Neutral Gas and Ion Mass Spectrometer (NGIMS) onboard the Mars Atmosphere and Volatile EvolutioN mission has provided critical insights into the composition and isotopic structure of Mars' ionosphere. However, significant model‐observation discrepancies of densities of some ion species suggest the presence of crosstalk, that is ...

Computer modeling and experimental work on the astrobiological implications of the martian subsurface ionising radiation environment [PDF]
, 2008 Any microbial life extant in the top meters of the martian subsurface is likely to be held dormant for long periods of time by the current permafrost conditions.

Global Occurrence of Solitary Waves in the Martian Magnetosphere
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract This letter presents a global occurrence of bipolar solitary waves (SWs) in the Martian magnetosphere. We utilized medium‐frequency electric field measurements from October 2014 to December 2023 from the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.

The Potential for a Networked Ionospheric Sounding Constellation
Space Weather, 2022 A novel networked sounding constellation mission concept is proposed. Radio sounding is the original sensing method that proved the existence of the ionosphere. Satellite‐borne sounders provided the first global observations of the terrestrial ionosphere
