Optical Tracking and Spectral Characterization of Cubesats for Operational Missions
… objects using a worldwide network of radar and optical sensors. However, in order to better protect space assets, there has been increased interest in not just knowing where a space object is, but what the object is. The optical and spectral characteristics of solar light reflected off of …

Vision-based Autonomous Navigation using Moon and Earth images
… approach to trajectory determination based on optical observation of nearby celestial bodies, and describes its development, implementation and testing. The initial idea was spurred by the need to give the Orion capsule, the next-generation manned spacecraft currently in development at NASA, a …

Initial Orbit Determination Error Analysis of Low-Earth Orbit Rocket Body Debris and Feasibility Study for Debris Cataloguing from One Optical Facility
… orbit determination (IOD) methods when limited observational data is available for low-Earth orbit (LEO) rocket body debris. The analysis will be conducted with data obtained from Lockheed Martin Space’s Space Object Tracking (SpOT) facility, focusing on their observational data from 2018 that …

Versatile Strategies for Multifunctional Polyolefins
… building blocks or as chromophores for optical observation. The single use or combination of these techniques has led to polyolefin-based materials that may in fact lower the barrier for the next-generation of functional polyolefins.

Einfluss von Strömungen auf die Entwicklung des Mikrogefüges bei der gerichteten Erstarrung von Al-Si- und Al-Si-Mg-Legierungen
… to flat isotherms and allowing the direct optical observation of the solidification process. Three pairs of Helmholtz coils around the cylindrical sample (120mm length, 8mm in diameter) induce a homogeneous rotating magnetic field (3mT and 6mT at 50Hz) being able to generate a controlled …

Studying viral-like particles using fluorescence fluctuation spectroscopy
… time a labeled protein passes through a tiny optical observation volume, it creates an observable fluctuation in fluorescence signal. Statistical analysis extracts information about the sample from these fluctuations. Through statistics, we can determine information about the transport …
