Abstract The Satellite for Orbital Aerodynamics Research (SOAR) is a 3U CubeSat mission
that aims to investigate the gas–surface interactions (GSIs) of different materials in the very …

Differential drag is a promising option to control the relative motion of distributed satellites in
the Very Low Earth Orbit regime which are not equipped with dedicated thrusting devices. A …

We present the advances on the development of a passive intakecollector system for Air-
Breathing Electric Propulsion platforms orbiting Earth at altitudes below 250 km. First, we …

We present a method to estimate the total neutral atmospheric density from precise orbit
determination of Low Earth Orbit (LEO) satellites. We derive the total atmospheric density by …

When the space age began, some aerodynamicists expected that the surfaces of spacecraft
would be cleaned by desorption in the high vacuum of space; while others, familiar with …

The ability to model atmospheric drag is critical for precise satellite orbit prediction below
1000 km altitudes. Uncertainty in atmospheric drag comes primarily from estimates of the …

Ambitious satellite constellation projects by commercial entities and the ease of access to
space in recent times have led to a dramatic proliferation of low-Earth space traffic. It …

High‐resolution mass density observations inferred from accelerometer measurements on
the CHAMP and GRACE satellites are employed to investigate the thermosphere mass …

The present contribution investigates the possibility to obtain thermospheric neutral density
estimates using satellite laser ranging (SLR) observations of low Earth orbiters (LEOs). This …

The estimation and modeling of drag effects on low altitude satellites and debris is a limiting
problem in the prediction of their orbits over time. Independent of the stochastic variations in …
