Accurate forecasts of thermosphere densities, realistic calculation of aerodynamic drag, and
propagation of the uncertainty on the predicted orbit positions are required for conjunction …

We present new neutral mass density and crosswind observations for the CHAMP, GRACE,
and GRACE-FO missions, filling the last gaps in our database of accelerometer-derived …

Understanding the variation of the Thermospheric Mass Density (TMD) is important for solar‐
terrestrial physics and applications for spacecraft safety. The thermosphere, as an open …

The increasing number of Resident Space Objects poses a serious threat to the safe
operation of satellites. Alongside with mitigation policies, it is fundamental to predict the …

The quality and distribution in time and space of available atmospheric observations are
crucial for the accuracy of semi-empirical thermosphere models. However, datasets can be …

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 …

Reducing space debris is a critical challenge in current space exploration. This study
