Mission Assurance for NASA JPL's Lunar Flashlight Mission

NASA missions are complex and high-stakes endeavors that require careful planning and execution to ensure success. Mission assurance is a critical aspect of these missions, as it is responsible for reducing risk, improving quality, and enhancing reliability. This presentation will explore the importance of mission assurance particular to the NASA JPL Lunar Flashlight mission and how it contributes to mission success. We will cover the key elements of mission assurance, including: fault protection, safe operator practices, and risk management as applied to Lunar Flashlight.

Advisor: Dr. Glenn Lightsey, Space Systems Design Laboratory (SSDL)

Current Developments of a Multi-Disciplinary Hypersonic Design Framework

In recent year, steady capital investment towards the development of novel hypersonic systems is increasing to compete with international competition and satisfy projected demands. As a contribution towards these developments, the Aerospace System Design Laboratory is developing a multidisciplinary design framework to analyze hypersonic vehicle concepts. The speaker will talk about current capabilities of the developing framework, mainly around parametric surrogate model generation, coupled analysis for weight estimation and sensitivity, and high mach engine cycle analysis.

Advisors: Dr. Kenneth Decker & Prof. Dimitri Mavris, Aerospace System Design Laboratory (ASDL)

B-Dot Attitude Determination and Control Algorithm for GT-2 CubeSat 

Attitude Determination and Control Systems are imperative for any spacecraft, regardless of size or complexity. GT-2, a 1U undergraduate built CubeSat, accomplishes this mission requirement through the use of magnetic spacecraft control. By utilizing Earth’s magnetic field, magnetic torquing devices known as magnetorquers are implemented to create small angular moments on the spacecraft. This efficient and reliable method for spacecraft control is commanded in flight software through an algorithm that relies on the time rate of change of the magnetic field vector B, and is hence known as a B-Dot controller. Although this technique has limitations, the applications and versatility offered to GT-2 with such ADCS capabilities both serve as a technology demonstration and lay the groundwork for potential imaging payloads on GT-3 and beyond.
