Small Satellite Conference

The SpaceCraft for Optical-based Position Estimation-1 (SCOPE-1) is a 3U CubeSat developed by the Texas Spacecraft Laboratory (TSL) at The University of Texas at Austin to demonstrate near real-time Position, Navigation, and Timing (PNT) estimation primarily using optical detections of Earth’s islands and archipelagos. The mission adapts algorithms originally developed for lunar crater-based PNT and applies them to terrestrial features for validation in low Earth orbit (LEO). SCOPE-1 features an onboard system combining Mask R-CNN-based surface-feature detection, catalog-based feature identification, and an extended Kalman filter (EKF) to estimate position and timing in near real-time. 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, …

Small Satellite Conference

The Canadian Space Agency’s (CSA) Quantum EncrYption and Science Satellite (QEYSSat) mission launching in late 2026 will be the first demonstration of ground-to-space Quantum Key Distribution (QKD) in Canada. For this system, the receiving platform is a microsatellite in low earth orbit and the photon source is hosted in a ground based Optical Quantum Ground Station (OQGS). Together, they will enable the creation and exchange of cryptographic keys, establishing secure quantum communications at a minimum distance of 500 km. In the first year of operations, experiments will be performed to demonstrate QKD as an uplink via Weak Coherent Pulse (WCP) …

Escape, Plasma And Acceleration Dynamics Explorers (Escapade) – Enabling A Low-Cost Mars Mission, Jeffrey S. Parker, Andrew Kohler, Mitchell Rosen, Lauren De Moudt, Robert Lillis, David Curtis, Ellen Taylor, Sasha Courtade, Daniel Cosgrove, Christophe Mandy, Antoine Bichara

Small Satellite Conference

The Escape, Plasma and Acceleration Dynamics Explorers (ESCAPADE) mission will provide a comprehensive picture of how solar wind energy flows through Mars’ unique hybrid magnetosphere to drive ion and sputtering escape. The mission has undergone several transformations to accommodate evolving launch constraints, highlighting its resilience and offering valuable insights for designing low-cost, adaptable Mars missions. This paper describes why and how ESCAPADE has pivoted, how the mission design accommodated the change, and what lessons have been learned. The objective is to illuminate how to design launch resiliency into a low-cost Mars mission.

ACMES will serve a one-year primary mission focused on technology demonstration, followed by a three-year science-based mission to provide valuable LWIR observations of the Earth’s surface. The …

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 …

Hitching A Ride On History: Nasa’S Space Launch System Artemis Ii Cubesats, Russell Lane, David Beaman, Courtney Ryals, David Hitt

Small Satellite Conference

In early 2026, NASA will launch the Artemis II mission, the second flight of its Orion spacecraft and Space Launch System (SLS) rocket. Artemis II will be the first crewed flight of the systems and will see four astronauts venture around the Moon as a key step toward establishing a long-term human presence in deep space. The 10-day flight will demonstrate NASA's foundational human deep space exploration capabilities. Launching along with Orion on SLS will be four 12U CubeSats developed through partnerships with space agencies around the world that are signatories of the Artemis Accords. The CubeSats will deploy in …

Small Satellite Conference

This Kinéis constellation is made of 25 30kg-class satellites, equipped with electric propulsion. The missions are dedicated to IoT (Internet of Things) connectivity and to AIS (Automatic Identification System) monitoring. The satellites were launched by batches of 5, the first took place in June 2024, the last one in March 2025.

The paper discusses how the Ground Control Segment was developed and validated within a complex system and with strong schedule constraints. The validation plan was designed to rapidly de-risk the challenges due to multi- satellite aspects, to focus on a …

Navigating The Ezie Path: Insights From A Cubesat's Trailblazing Journey Through Nasa Mission Development, Marc Hoffman, Rebecca Wind-Kelly, Nelli Mosavi-Hoyer

Small Satellite Conference

The Electrojet Zeeman Imaging Explorer (EZIE) is a low-cost, multi-spacecraft mission that seeks to capture the magnetic signature of the powerful electrojet currents flowing within the Earth's upper atmosphere. Equipped with the innovative Microwave Electrojet Magnetogram instrument, three identical 6U CubeSats fly in a "pearls-on-a-string" configuration in sun-synchronous, low Earth orbit, crossing the auroral oval over 8,000 times during its 18-month lifetime. As a NASA-sponsored, Category 3, Risk Classification D mission, EZIE accommodates a higher-risk tolerance and moderate budget while offering a substantial return in science. In less than 40 months of development, the project managed the convergence of sponsor …
