A concept for a passive neutral gas concentrator that facilitates the analysis of rarefied
atmospheres using mass spectrometry on spacecraft has been developed. The efficiency of …

The greatest concentration of spacecraft and space debris resides in an orbital band
between 100 and 2000 km altitude, classified as low‐Earth orbit (LEO). Of these space …

The space weather research community relies heavily on thermospheric density data to
understand long‐term thermospheric variability, construct assimilative, empirical, and …

A comprehensive numerical study is performed to investigate gas flows inside the inlet of an
atmosphere-breathing electric propulsion (ABEP) system operating in the upper atmosphere …

Abstract Objects in a flowing plasma may exchange momentum both directly, through gas-
surface interactions, and indirectly, through field effects. Applying a control surface approach …

The accuracy of atmospheric density measurements inferred from satellite drag is limited by
errors in drag coefficient estimates. In this work, we use a unique opportunity in which the …

Space traffic management in a congested Low Earth Orbit (LEO) environment requires an
understanding of all the forces influencing a body's motion to enable essential precise orbit …

Presented herein is the progress on developing a new mass analyzer for analysis of the
exospheres of planets, moons, and primitive bodies, such as found at Europa or Enceladus …

Accurate modelling of the aerodynamic interaction between the space environment and Low
Earth Orbit (LEO) objects improves our ability to understand, predict and control their motion …
