Radio occultation (RO) is a powerful tool for remotely sensing the atmosphere, producing globally distributed soundings with both high vertical resolution and high temperature retrieval accuracy, especially in the stratosphere. The spatial distributi

The advent of radio occultation (RO) instruments aboard CubeSats leads to the possibility of a mission to sound atmospheric internal gravity waves if such satellites are deployed in close-flying constellation. The satellites in the constellation must

Techniques and Instrumentation for Detection of Exoplanets X.
A key aspect of the search for earth-like exoplanets with direct imaging, is determining if the exoplanet is in the habitable zone. For mission design of potential future direct imaging missions, such as HabEx and LUVOIR, an efficient cadence of obse

High-contrast images from future space-based telescopes may contain several planets from multiplanet systems and potentially a few planet-like speckles. When taken several months apart, the short-period planets and speckles will appear to move signif

Orbital forecasting is an essential part of precision satellite operations. The largest contributor to orbital propagation error in low orbits is atmospheric drag, which varies widely due to altitude, latitude, and solar activity. Accurate in-situ me
