We present the validation of ADBSat, a novel implementation of the panel method including
a fast pseudo-shading algorithm, that can quickly and accurately determine the forces and …

For satellites in the Low Earth Orbit (LEO) region, the drag coefficient is a primary source of
uncertainty for orbit determination and prediction. Researchers at the Los Alamos National …

To study the influence of energy accommodation of scattering gas molecules on flow fields
during large expired spacecraft reentry, a more elaborated gas-surface interaction model …

Differential aerodynamic forces are a promising propellant-less option to control satellite
formation flight. To this day, satellite lift is the most frequently neglected and, as a …

In recent years, air-breathing electric propulsion emerged as a potential enabling
technology for long-duration space missions in Very Low Earth Orbit (VLEO). In this work, we …

Orbital lifetime estimation is a problem of great timeliness and importance in astrodynamics.
In view of the stochastic nature of the thermosphere and of the complexity of drag modeling …

Thermospheric wind measurements obtained from linear non-gravitational accelerations of
the Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite show …

Drag coefficients are a large source of uncertainty when predicting the aerodynamic forces
on orbiting satellites. Accordingly, the focus of this research is to improve the fidelity of drag …

A gridded ion thruster running on two different propellants (Xenon and Iodine) and sited
within a 3U CubeSat satellite, is modelled in a Low-Earth-Orbit (altitude 400 km), using a …

The work is devoted to researching the effects of reflected gas molecules' states on
aerodynamic properties and surface characteristic quantities distributions. Within the …
