By encouraging students to interact with multimedia resources—including animated videos, podcasts, news articles, and the Russian National Corpora—the curriculum aims to enhance both language and media literacy skills. Media Literacy’s Five Key Framework is applied to guide students in analyzing media critically while producing academic projects and cultural responses. We present a curriculum that fosters …

Successful Demonstrations Of The Elroi Satellite License Plate, David M. Palmer, Rebecca M. Holmes Sandoval

Small Satellite Conference

ELROI (Extremely Low Resource Optical Identifier) is a system that attaches a small, cheap, low power, autonomous blinking light to a satellite or other space object to allow it to be unambiguously identified by ground observations using a small telescope. This can provide a resolution to the space object identification problem for future launches at minimal technical and financial costs to the satellite operator. In 2024, two satellites carrying ELROI Space Object Tracking Units were successfully launched on separate rocket launches. As reported here, in both cases ELROI provided the first definitive identification of each satellite, sooner than achieved by …

Vision-Based Dynamic Tasking For Earth-Observing Satellite Constellations, Shreeyam Kacker, Kerri Cahoy, Kiruthika Devaraj, Işıl Demir, Steve Chien

Small Satellite Conference

Unpredictable phenomena such as cloud coverage pose a challenge for conventional Earth observation. Long lead times can cause conditions to change between forecasting, scheduling, and image capture, leading to suboptimal observations. To combat this, dynamic tasking has been proposed as a mission concept, where perception and autonomy are moved onboard the spacecraft in order to quickly respond to changes in the spacecraft’s imaging schedule, leveraging the compute power available in modern Earth-observing spacecraft. In this work, we explore the use of a wide field-of-view body-fixed lookahead sensor, separate from the main imaging payload, to evaluate the real-time utility of upcoming …

The SCOPE-1 spacecraft will be built …

Implementation Of A Standardized Protocol For Early Detection Of Coronary Artery Disease, Erika Sosa

DNP and Student Works

Cardiovascular disease (CVD) remains the leading cause of mortality worldwide, accounting for over 931,000 deaths in the United States in 2021. The growing prevalence of CVD, coupled with increased life expectancy, underscores the need for early detection and intervention to mitigate its impact on patients, families, and society. Timely identification of subclinical heart disease can significantly improve outcomes by allowing earlier implementation of preventive strategies.

This Doctor of Nursing Practice (DNP) project implemented a primary care–based protocol for the early detection of coronary artery disease (CAD) using the Coronary Artery Calcium (CAC) score. The CAC score, a non-invasive imaging modality, …

Teachers’ Challenges In Implementing The New Mexican School’S Educational Model, Mayra Margarito Gaspar

Journal of Educational Research and Practice

This scholarly essay explores the challenges that teachers face in implementing the Nueva Escuela Mexicana (NEM) [new Mexican school] educational model, which prioritizes project-based and interdisciplinary learning over subject-based instruction. The NEM’s flexible approach requires teachers to independently structure lessons, ensuring continuity without a predefined thematic sequence. Collaboration is essential, yet many educators struggle with interdisciplinary coordination, especially in secondary education. Limited planning time and curricular flexibility further complicate implementation. Teachers in marginalized areas also face resource constraints, which hinders project-based learning. Additionally, the NEM’s textbooks, which are designed for integrative learning, lack clear organization and guidelines and make them …

Lightsheet Anomaly Resolution And Debris Observation (Larado), Andrew Nicholas, Kenneth Marr, Josh Wolf, Charles Brown, Vanessa Kooi, Ted Finne, Scott Budzien, Cosimos Cendo, Ivan Galysh

Small Satellite Conference

Space objects in the size range of 0.1 mm to 3 cm are not currently trackable but have enough kinetic energy for lethal consequences to spacecraft. Small orbital debris poses a risk to most space missions; the detection of this debris requires a combination of a large sensor area and large time coverage. For example, a sensor with a time area product of 3 m²years can make a significant contribution to our understanding of the near-Earth small debris population. Deploying large sensors like physical witness plates is resource intensive, due to their size and weight. The light sheet …

Finch Eye: The Optical And Optomechanical Design Of A Grism-Based Swir Hyperspectral Imaging Payload For A 3u Cubesat, Iliya Shofman, Mario Ghio Neto, Theaswanth Ganesh, Kenya He, Aidan Armstrong, Ksenya Narkevich

Small Satellite Conference

Crop residue is an important metric used for agricultural land-use monitoring and climate science research. Estimating crop residue coverage is essential to sustainable agricultural practices. There already exist scientific hyperspectral satellites, such as PRISMA and EnMAP, that can be used for crop residue estimation; however, they are very expensive to build and cannot be monopolized by individual farms. This leaves a gap in satellite remote sensing solutions which can be deployed operationally and at the farm scale. We seek to fill this gap by developing a low-cost satellite solution for crop residue estimation. The University of Toronto Aerospace Team is …

Extremely Low-Cost Optical Receiver For Extremely Low Resource Optical Identifiers, Ashin Alex, Joseph Ashby, Kevin Walker, Brennan Chai, Catherine Qualtrough, John E. Cater, Nicholas J. Rattenbury

Small Satellite Conference

Space object identification (SOI) is essential for space traffic management, situational awareness, and mission operations. The Extremely Low Resource Optical Identifier (ELROI), developed by Los Alamos National Laboratory, provides a persistent and interference-free identification method for small satellites through a self-powered optical beacon. ELROI transmits a unique identification code via low-power laser pulses, enabling ground stations to identify spaceborne assets without relying on traditional radio beacons. However, the efficacy of the ELROI system relies on the widespread availability of highly sensitive and cost-effective ground-based optical receivers. To address this need, we are developing a low-cost optical receiver capable of detecting …

Satellite Navigation With Earth Islands For Scope-1, S. Anand Agrawal, Brandon A. Jones

Small Satellite Conference

Spacecraft optical navigation can deliver autonomous navigation onboard when Earth-based tracking is saturated, obstructed, or impractical. Optical navigation relies on the correspondences between detected and known or mapped features in imagery to extract position and/or velocity, and data-driven methods, which directly leverage collected data to learn, can improve detection performance. This paper presents an initial data-driven Earth-based detection system using islands as landmarks for the SpaceCraft for Optical- based Position Estimation-1 (SCOPE-1) 3U CubeSat, which will be paired on board with a physics-based estimation framework. The system consists of an island detector trained on Earth observation imagery of islands, an …

Simulation-Based Evaluation Of Dual-Mode Propulsion Strategies For Small Satellite Collision Avoidance, Michael Harrigan, Charles Cundiff, Joshua L. Rovey, Victoria Coverstone

Small Satellite Conference

As Low Earth Orbit (LEO) becomes increasingly congested, small satellite missions face growing challenges in executing effective collision avoidance maneuvers under limited time and propellant constraints. Dual-mode propulsion systems, combining high-thrust chemical and high-specific impulse electric modes, offer a promising approach to balance rapid response with propellant conservation. This paper evaluates how such systems can be applied to reduce the Probability of Collision (PC) within constrained maneuver windows using sequential chemical-electric burns.

A FreeFlyer-based simulation framework models dual-mode collision avoidance maneuvers across synthetic LEO scenarios. For each case, user-defined mission parameters, such as lead time, PC threshold, and orbital altitude, …

Toward Trusted Onboard Ai: Advancing Small Satellite Operations Using Reinforcement Learning, Cannon Whitney, Joseph Melville

Small Satellite Conference

A Reinforcement Learning (RL) algorithm was developed for command automation onboard a 3U CubeSat. This effort focused on the implementation of macro Control Action Reinforcement Learning (CARL), a technique in which an onboard agent is provided with compiled information based on live telemetry as its observation. The agent uses this information to produce high-level actions, such as adjusting attitude to solar pointing, which are then translated into control algorithms and executed through lower-level instructions. Once trust in the onboard agent is established, real-time environmental information can be leveraged for faster response times and reduced reliance on ground control. The approach …
