A solar terminator wave in thermosphere neutral densities measured by the CHAMP satellite

Vertical Motion Field in the Middle Thermosphere from Satellite Drag Densities

The vertical motion field in the thermosphere is calculated from the continuity equation. This calculation ik based on a field of horizontal winds and an intermediate model of the thermospheric temperature field consistent with the density structure inferred from satellite drag data. The vertical motion consists of a component due to rise and fall of constant pressure surfaces and a component d...

Solar Flux Variability and Mars’ Thermosphere Densities Derived from Orbital Tracking Data

Impact of Solar Forcing on Thermospheric Densities and Spacecraft Orbits from CHAMP and GRACE

The Effect of Solar Particles in the Choice of Alloy Shielding in a Satellite

The damages and logical failures in dierent parts of a satellite may occur during a solar event, when a bulk of solar energetic particles approaching the Earth. During solar events, these particles may cause extensive damages which are even permanent (hard errors). A way of damage reduction is designing a proper coating as the fuselage. As protons are the major component of solar particles and ...

Solar Cycle Variability of the Thermospheres of Mars and Earth

This paper comparatively examines long-term variations in the thermospheres of Mars and Earth, from the solar maximum of 2002-2003 to the deep solar minimum of 2009-2010. Data employed include densities and exosphere temperatures derived from orbital drag analyses of the Mars Odyssey (MO) satellite for Mars, and accelerometer measurements on the CHAMP satellite for Earth. Derivation of thermosp...
