title: Modeling Considerations for Developing Deep Space Autonomous Spacecraft and Simulators

description: Over the last two decades, space exploration systems have incorporated increasing levels of onboard autonomy to perform mission-critical tasks in time-sensitive scenarios or to bolster operational productivity for long-duration missions. Such systems use models of spacecraft subsystems and the environment to enable the execution of autonomous functions (functional-level autonomy) within limited time windows and/or with constraints. These models and constraints are carefully crafted by experts on the ground and uploaded to the spacecraft via prescribed safe command sequences for the spacecraft to execute. Such practice is limited in its efficacy for scenarios that demand greater operational flexibility. To extend the limited scope of autonomy used in prior missions for operation in distant and complex environments, there is a need to further develop and mature autonomy that jointly reasons over multiple subsystems, which we term system-level autonomy. System-level autonomy establishes situational awareness that resolves conflicting information across subsystems, which may necessitate the refinement and interconnection of the underlying spacecraft and environment onboard models. However, with a limited understanding of the assumptions and tradeoffs of modeling to arbitrary extents, designing onboard models to support system-level capabilities presents a significant challenge. For example, simple onboard models that exclude cross-subsystem effects may compromise the efficacy of an autonomous spacecraft, while complex models that capture interdependencies among spacecraft subsystems and the environment may be infeasible to simulate under the real-world operating constraints of the spacecraft (e.g., limited access to spacecraft and environment states, and computational resources). In this paper, we provide a detailed analysis of the increasing levels of model fidelity for several key spacecraft subsystems, with the goal of informing future spacecraft functional- and systemlevel autonomy algorithms and the physics-based simulators on which they are validated. We do not argue for the adoption of a particular fidelity class of models but, instead, highlight the potential tradeoffs and opportunities associated with the use of models for onboard autonomy and in physics-based simulators at various fidelity levels. We ground our analysis in the context of deep space exploration of small bodies, an emerging frontier for autonomous spacecraft operation in space, where the choice of models employed onboard the spacecraft may determine mission success. We conduct our experiments in the Multi- Spacecraft Concept and Autonomy Tool (MuSCAT), a software suite for developing spacecraft autonomy algorithms.

title: Robust Detection and Identification of Simultaneous Sensor and Actuator Faults

description: In this work, we address the problem of fault detection, identification, and recovery (FDIR) for simultaneous actuator and sensor degradation. Prior studies have considered sensor degradation to some extent, but results for systems that do not have sensor redundancy while experiencing simultaneous actuator degradation are lacking. We present a novel method for robustly detecting and identifying sensor degradation in the presence of potential bounded actuator degradation modes under the influence of process and output noise. Subsequently, we develop novel theory for guaranteed forward reachability in the case of stochastic differential equations, as well as theory for robust fault detection for dynamical systems. Our approach enables in robust state estimation under sensor degradation, namely in the framework of zonotopic–Gaussian Kalman filters (ZGKF), providing an end-to-end FDIR framework for simultaneous sensor and actuator faults in a multi-agent setting. We apply our approach, which can be run in real time, to a realistic model of rigid-body satellite attitude dynamics in the presence gyroscope bias and gain changes, as well as changes in the thruster efficacy. We also present a second examples based on a multi-agent rover mission with limited periodic information sharing.

title: Assessment of Propellant Droplet Contamination Effects on the Europa Clipper Spacecraft

description: NASA's Europa Clipper spacecraft will carry nine science instruments to investigate whether Jupiter’s moon Europa has an environment that could support life. Europa Clipper is the largest spacecraft NASA has flown for a planetary mission. With solar arrays fully extended the spacecraft spans over 30 meters. At launch, nearly half of Europa Clipper’s mass is propellant which will be consumed during travel to Jupiter, inserting the spacecraft into orbit around Jupiter, and to perform almost 50 flybys of Europa. Europa Clipper’s propulsion system has 24 bipropellant engines which will process nearly 2750 kg of fuel and oxidizer during the course of the mission. During propulsion system operation liquid droplets of unburned fuel and oxidizer are expelled from the engines. An empirical bipropellant plume contamination model that was originally developed for International Space Station thrusters was applied to investigate droplet effects on the Europa Clipper spacecraft. Unburned propellant droplets can cause damage to spacecraft materials by chemical reactions and mechanical damage exhibited by pitting surfaces. Bounding estimates for propellant droplet fluxes to Europa Clipper surfaces were obtained using the empirical model. Based on material testing results, estimates of damage to materials used for thermal blankets, solar arrays, and instruments were assessed to determine the impact to spacecraft thermal, power and science systems. Where needed, design changes were made to mitigate deleterious effects caused by propulsion system operation.

title: Characterization of surface parallel mirror actuation using preloaded commercial lead zirconate titanate (PZT) stacks

description: The next generation of space telescopes will require large, segmented apertures for observations in the near ultraviolet through mid- and far-infrared regions to enable new science ranging from exoplanet characterization to precision astronomical observations that refine astrophysics models. To meet these challenges, we are developing instrumented (strain gauge) surface parallel actuators (SPAs) that are robust and can meet the stringent requirements of mass and cost per m2. We have developed a surface parallel mirror test piece and a set of flexured actuators that maintain compression in the piezoelectric stack elements at all times. The characterization work of these actuators is directed at understanding the performance of flexure piezoelectric multilayer stack actuator operation when embedded in the mirror. To determine the influence functions for each actuator position, we will report the measured stroke/strain and charge/capacitance versus voltage curves for all 42 preloaded actuators. Although designed to operate under close loop control via feedback from the strain gauge initial testing on bare lead zirconate titanate (PZT) stack actuators suggests that by driving the stack to a known domain state we could perform open loop control in the actuators to levels of  0.3 m. We will also report on creep for the actuators and cross actuation for each unique actuator position as well as discuss approaches to mitigating the effect on open loop control error. Thermal studies of flextensional actuators embedded in analog rib structures down to 100K will also be presented.

title: N-WLASL2000

description: N-WLASL dataset is a synthetic event-based dataset comprising 21,093 samples across 2,000 glosses. The dataset was collected using an event camera to shoot toward an LCD monitor. The monitor plays video frames from WLASL, the largest public word-level American Sign Language dataset. We use the event camera DAVIS346 with a resolution of 346x260 to record the display. The video resolution of WLASL is 256x256 and the frame rate is 25Hz. To ensure accurate recording of the display, we have implemented three video pre-processing procedures using the python-opencv and dv packages in Python. These procedures are as follows:Add black paddings and red borders around video frames to increase their size to 346x260.Center the video frames on the monitor display after scaling them to 1428x1080 in the original aspect ratio.Display all videos sequentially at the original frame rate of 25Hz and pause the first frame of each video for 500ms to prevent event bursts brought on by swapping videos.

description: This study was designed to assess the impacts of noise disturbance on sleep and physiology, and comprised several parts:
An in-lab pilot study to assess the effects of 20 second and 3 minute noise exposures during sleep in healthy sleepers, with hearing data and subjective and objective sleep data (n = 25) 
Computer assisted telephone interview (survey) of individuals living in proximity to rural wind farms, residents close to busy urban roads, or those in quiet rural areas (n = 542)
Multi-day field study recording sleep and acoustic characteristics in individual residences close to wind farms (n = 27) In laboratory multi-day study (n = 68), with individuals reporting either: wind farm noise exposed with subjective sleep disruption, proximity to a wind farm but no subjective sleep disturbance, proximity to a busy road with subjective sleep disturbance, and comparator population from quiet rural locations. Participants had an acclimation night in the sleep laboratory and were then exposed to various sound conditions during sleep on the following nights. Recordings include subjective and objective sleep and hearing data, and various questionnaires at multiple timepoints. 
Please note the due to ethical considerations and the impracticality of de-identification, individual participant data is not able to be released for some items, and only summary or aggregate data will be reported and available for sharing.

title: Shellfish aquaculture farms as foraging habitat for nearshore fishes and crabs

description: This is the dataset used for the analysis in our paper. The file contains species counts and behavior classifications of nearshore fish and crabs taken from time-lapse underwater video. Also included are habitat transect data from each site. Presence/absence of zostera marina and zostera japonica eelgrass, algae, as well as eelgrass metrics were quantified in the transects. The metadata spreadsheet contains descriptions of each column in the datasheet. This data was collected at shellfish aquaculture farm sites across Puget Sound, Washington, USA in 2017, 2018, and 2019 using underwater timelapse video cameras and habitat transects. Transects were done with 1/4 meter^2 quadrat divided into 25 10x10cm^2 squares, each quadrat was measured 5 times along a 30 meter line parallel to shore. Video was recorded in 2 minute lengths every 10 minutes starting 1 hour before high tide, going to 1 hour after high tide, using cameras positioned approximately 18 inches off the substrate. PVC stakes were used to mark a 1 meter square of camera visibility and organisms observed within that 1 meter square were recorded. For more information, see my chapter 1 thesis.
