IN-SITU EXPLORATION OF EARTH’S ATMOSPHERE USING NOVEL SPACECRAFT DESIGN
, 2009 Altitudes between 40 and 140 km are not accessible for conventional aircraft and spacecraft for long-term duration. In particular the region around 100 km, the upper mesosphere and lower thermosphere (UMLT), is of great interest to scientists and ...

Thermal Escape of Atomic Hydrogen on Mars: A Comprehensive View With a General Circulation Model
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Mars loses water mainly through the photodissociation of water vapor, followed by the thermal escape of light hydrogen atoms. Observations have revealed large seasonal variations in hydrogen concentration in the upper thermosphere, peaking during southern summers and intensifying during dust storms.

, 1986 It has recently been demonstrated that the dramatic effects of plasma precipitation and convection on the composition and dynamics of the polar thermosphere and ionosphere include a number of strong interactive, or feedback, processes.

Thermal Effects of Gravity Waves in Planetary Atmospheres
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Internal atmospheric acoustic‐gravity waves substantially drive the global dynamical, thermal, and compositional structure of planetary atmospheres. While the dynamical effects of acoustic‐gravity waves have been extensively studied, especially on Earth and Mars, their thermal effects are insufficiently explored in planetary atmospheres.

A Machine‐Learning‐Based Global Thermospheric Density Forecasting Model
Space Weather, Volume 24, Issue 6, June 2026.Abstract Thermospheric mass density governs aerodynamic drag in low Earth orbit and is a primary source of uncertainty in orbit prediction and conjunction assessment, particularly during geomagnetic disturbances. We present AETHER‐P3 ${\mathrm{P}}^{3}$ (Accelerometer‐driven Estimation of THERmospheric density–A Physics‐Informed Probabilistic Prediction

Calibration and Fusion of GOLD‐Inferred TEC Data With Ground‐Based TEC
Space Weather, Volume 24, Issue 6, June 2026.Abstract Ground‐based Global Navigation Satellite System (GNSS) receivers provide primary total electron content (TEC) measurements used to monitor ionospheric variability, yet their sparse distribution over oceanic and equatorial regions limits global coverage and model accuracy.

An HHT–ANN Framework for Short‐Term Kp Forecasting
Space Weather, Volume 24, Issue 6, June 2026.Abstract The geomagnetic activity index Kp is an important indicator of solar wind–magnetosphere coupling, and accurate 3‐hr‐ahead forecasting is important for space‐weather monitoring and warning. Because upstream solar wind and interplanetary magnetic field (IMF) signals are strongly nonlinear and nonstationary, methods based only on conventional ...

The Martian Thermosphere/Ionosphere: Ancient and Modern
, 1999 We review our current understanding of the thermosphere and ionosphere of Mars at high and low solar activities, including density profiles of ions and minor neutral species, their variation with solar activity, and current and escape rates.

Regional and Seasonal Effects of Geomagnetic Storms on Terrestrial Weather
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract It has long been a mystery why small Total Solar Irradiation changes have significant effects on Earth's climate. Solar cycle correlation studies abound but cannot conclusively point to a viable physical mechanism. Here, I show that geomagnetic storms have a profound terrestrial weather impact.
