Dr. Crowley has diverse interests, including modeling and simulation, data analysis and instrument development for the atmospheres of Earth and Mars. He has authored (or co-authored) over 60 publications in refereed journals, ranging from the magnetosphere to the mesosphere. His current interests include the energy inputs to the thermosphere-ionosphere system, and their effects on the neutral density and composition; the high latitude convection pattern, it’s specification, and penetration to lower latitudes; atmospheric waves.

Frederick D. Wilder
Postdoctoral Researcher
Ph.D., Electrical Engineering, Virginia Tech, VA, 2011

Email: (@astraspace.net) rwilder

Dr. Wilder has been working with ASTRA since 2011. His research interests include magnetospheric physics, magnetosphere-ionosphere-thermosphere coupling, system science, radar remote sensing of the ionosphere, data assimilation, global positioning systems, and radio occultation. He currently holds the NSF Atmospheric and Geospace Sciences Post-Doctoral Research Fellowship (AGS-PRF) at the Laboratory for Atmospheric and Space Physics in the University of Colorado, Boulder, and continues to collaborate closely with ASTRA.

Marcin Pilinski
Research Engineer
PhD, Aerospace Engineering Sciences, University of Colorado, 2011

Dr. Pilinski’s current research focus is in the areas of thermospheric physics, satellite drag, and gas-surface interactions (GSI) in the free-stream and transition regimes. His work includes the computation of specific drag coefficient values for aeronomic spacecraft such as CHAMP as well as the evaluation and development of general GSI models appropriate for flight through the earth’s thermosphere. He has analyzed satellite drag data collected by the Air Force Space Command and compared it with Monte Carlo analyses.
