Improvements to LEO Tracking on The Portable Telescope for Lasercom (PorTeL)
Publicerad 2023“…This thesis focuses on updates made to PorTeL to enable it to receive optical downlinks from the CubeSat Laser Infrared CrosslinK (CLICK) mission satellites in low-Earth orbit (LEO). We show that PorTeL is able to track CLICK-A with an accuracy of 11.1 arcseconds, well within its requirement of 21.8 arcseconds.…”

Reduced-Order Atmospheric Density Modeling for LEO Satellite Orbital Reentry Prediction
Publicerad 2023“…Atmospheric density modeling and uncertainty quantification for fast and accurate orbit propagation are vital to drag force estimation for satellite reentry prediction and conjunction assessment in today's increasingly cluttered Low Earth Orbit (LEO) environment. Current density models can be computationally expensive, and often contain large errors, which make density modeling a leading cause of uncertainty in drag estimation. …”

Design Options to Address Submersion Criticality for Low-Enriched Uranium Nuclear Thermal Propulsion Rocket
Publicerad 2023“…Missions to Mars with eventual establishment of a Mars base/colony will require a versatile and consistent transportation method between Earth and Mars. Nuclear thermal propulsion (NTP) is well suited to be the main propulsion mechanism for interspace travel due to its high specific impulse. …”

Time traveling––An intuitive grasp of time takes time
Publicerad 2023“…On later autumn days, they marked that pillar’s shadow in another color and discussed what these chalk marks revealed about sun, earth and the seasons. A hollow tube exposed the motion of stars; an astrolabe provided a window into the world of ancient observers; the Greek Antikythera mechanism posed an unsolvable puzzle from the past. …”
