Small Satellite Conference

Reliance on fossil fuels, combined with the physical limits of ground-based solar arrays, makes a strong case for collecting solar energy in orbit. Earth intercepts roughly 1.4 kW/m² at the top of the atmosphere, but absorption by carbon dioxide and water vapour and atmospheric scattering cut peak surface intensity to about 1.1 kW/m², this results in an over a 20% reduction. While inclination, time of day, and weather restrict that to a narrow band of land for a few hours each day.

The Solar Incident Energy Relay Array (SIERA) is a proposed mission that will create a single 6U CubeSat …

New Frontiers In Diagnosing Equine Lameness, Hyrum Hoopes, Karl Hoopes

All Current Publications

Lameness is one of the most common and expensive health problems seen in horses. Modern technology allows veterinarians to look beneath the surface. Tools such as artificial intelligence (AI), computed tomography (CT), magnetic resonance imaging (MRI), digital radiography (X-rays), nuclear scintigraphy, ultrasound, and positron emission tomography (PET) give clearer, more detailed pictures of what’s happening inside the horse’s leg. Each technology offers different advantages, from identifying uneven movement to revealing hidden damage within bones, joints, or soft tissues. When combined with veterinary visual evaluation, they help pinpoint the cause of lameness faster and more accurately than ever before.

Small Satellite Conference

Large constellations of SmallSats in Low Earth Orbit (LEO) are now delivering critical capabilities for missions in Earth observation, navigation, and communications. Very Low Earth Orbit (VLEO), defined here as below 400 km altitude, is emerging as a new frontier for SmallSat constellations due to its unique advantages. VLEO offers improved spatial resolution for Earth observations, reduced latency, increased signal power, and a naturally self-cleaning orbital environment. However, operating spacecraft in VLEO is non-trivial as the spacecraft must overcome the residual atmosphere at these altitudes and the resulting increase in aerodynamic drag and atomic oxygen fluence. As interest grows in …

Operational Challenges And Lessons Learned For Very Low Earth Orbit Cubesats, Adrian Bryant, Angela Crews, Sierra Flynn, Scott Gennari, Marcin Pilinksi, Nicholas Ratajczyk

Small Satellite Conference

Interest in Very Low Earth Orbit (VLEO) for small satellite applications has surged in the past half-decade, from industry, scientific, and governmental institutions. Operating at VLEO altitudes is incredibly challenging. The density of the residual atmosphere, and therefore the drag force experienced, grows exponentially as the orbital altitude decreases. The high-drag environment complicates orbit determination, minimizes anomaly response time, increases momentum management requirements, and may require significant re-concepting of operations. The Laboratory for Atmospheric and Space Physics (LASP) SmallSat Operations (SMOPS) group had the unique opportunity to partner with the University of Colorado Boulder National Security Initiatives (CU NSI) and …

Toward Trainable Ai Agents For Satellite Operations, Haley Calderon, Vaibhav Bhosale, Ketan Bhardwaj, Ada Gavrilovska

Small Satellite Conference

Low Earth orbit is increasingly crowded, and a growing share of it is flown by universities and small operators. These teams must detect and respond to on-orbit anomalies with far less staff, expertise, and tooling than large operators, and a single missed anomaly can end a mission. We present COMET, a ground-based operator agent that helps a small team both detect anomalies and diagnose them. COMET pairs a learned detector with a retrieval-augmented diagnosis stage. An LSTM autoencoder flags anomalous telemetry windows, and a language model explains each one against the mission’s own documentation, procedures, and prior operational records. Because …

Passive Thermal Imaging And Failure Detection Of Large-Area Space Structures Using Spin Crossover Composite Skins, Edward Pomianek, Codrin Tugui, Denise Maria De Andrade, Mihai Duduta

Small Satellite Conference

Deployable solar arrays are among the most failure-prone structures on spacecraft, and on small satellites their large area, low mass, and mechanical complexity make faults both more likely and harder to observe. Electrostatic discharge, string arcing, and localized hot spots can degrade or disable an array, yet the mass and harness penalties of distributed point sensors are difficult to accommodate within CubeSat resource budgets. This paper presents a passive, camera-readable sensing skin based on spin crossover (SCO) composite films that converts thermal events on a large-area structure into persistent optical information. The active material, [Fe(NH₂trz)₃]Br_{2 …}

Autonomous Reinforcement Learning Astrobee Control With Low Swap Neuromorphic Hardware, Kenneth Stewart, Roxana Leontie, Samantha Chapin, Joe Hays, Sumit Bam Shrestha, Carl Glen Henshaw

Small Satellite Conference

We present an end-to-end pipeline for deploying neural networks on low SWaP neuromorphic hardware to control a CubeSat like robot. As a test case, we use a reinforcement learning (RL)-trained Artificial Neural Networks (ANNs) on neuromorphic hardware by converting them into spiking Sigma-Delta Neural Networks (SDNNs) for controlling the NASA Astrobee free-flying robot, similar to a previously space-validated controller demonstrated on robotic hardware. We demonstrate that an ANN trained entirely in simulation can be transformed into an SDNN compatible with Intel’s Loihi 2 neuromorphic architecture, enabling low-latency and energy-efficient inference. The SDNN is deployed on Loihi 2, then evaluated in …

Determining The Feasibility Of A Habituation Assessment In Managed Red Wolves, Emily C. Lynch, Joseph W. Hinton, Jennifer B. Nagashima, Curtis Malott, Natalie J. Johnson, Emily Haering, Robin Petersen, Allison Johnson, Julie K. Young

Wildland Resources Faculty Publications

For species extirpated from the wild, ex situ breeding programs are essential for providing the individuals necessary for re-establishing wild populations through reintroductions. However, repeated exposure to humans under managed care may reduce wariness and alter behavioral responses in ways that are maladaptive after release. Although some pre-release behaviors reflect natural responses essential for survival and reproduction, others may result from habituation to humans and increase the risk of conflict, recapture, or mortality following translocation. These risks underscore the need for behavioral assessments to help identify appropriate candidates for release. However, because the assessments themselves require some exposure to humans, …

Is Hanpp A Stressor Of Bird Species Richness?, Kaeli Mueller, Gustavo Ovando-Montejo, Christopher Lant

Environment and Society Student Research

One of the leading drivers of biodiversity loss is land use change due to the ever-increasing demand for food, livestock feed, biofiber, and biofuel. The concept of human appropriation of net primary production (HANPP) was developed to measure the impact that humans have on the environment by accounting for biomass removed from the environment in the form of crops, timber, and grazing. The species–energy hypothesis is an established ecological hypothesis postulating that greater species diversity is correlated with higher levels of energy from plant productivity; this can be measured as net primary production minus harvested HANPP or NPP_ecological. …
