Development Of A Compliant Mechanism Mechanical Battery For Satellite Applications, Trevor Carter, Bryce Christensen, Ryan Day, Anthony Bridge

Small Satellite Conference

Objective:

Traditional space power systems face severe limitations: chemical batteries decay in extreme thermal swings or drain over long dormant periods, and radioactive units lack the specific power needed for peak operational loads. BYU Rocketry’s Phoenix payload, a 3U CubeSat that competed in the 2026 SDL Payload Challenge addresses these gaps. Phoenix is a proof-of-concept mechanical battery that augments primary power systems, enabling peak-load operation and recovery from dormancy.

Micro-Servicer Swarms For Responsive Smallsat Sustainment: The Sdaw Mothership Architecture, Wanjiku Chebet Kanjumba

Small Satellite Conference

The Challenge:

Sustaining The Mega-Constellation Era: LEO has shifted from a sparse domain into critical global infrastructure. With thousands of satellites on-orbit and tens of thousands more planned, sustainability is no longer guaranteed by launch activity alone; it depends on the ability to service, repair, and responsibly dispose of assets at scale.

• 7,500+ operational satellites in LEO (2024); 50,000+ projected within a decade
• 1,500+ trackable fragments from the 2021 Russian ASAT test; 1,700+ Starlink avoidance maneuvers followed
• ≥ 5 / yr large debris objects removed from LEO yearly to stabilize it (Liou & Johnson)

Originally an atmospheric data experiment, it has evolved into a modular testbed supporting missions for both internal research and external student organizations.

Minimum Variable Speed Control Moment Gyros (Vscmg) Cluster Sizing For Full Three-Axis Smallsat Attitude Control: A Numerical Study, Khang Nguyen, Christopher Damaren

Small Satellite Conference

Small satellites demand high-resolution imaging, optical inter-satellite links, precision science — demand agile, accurate attitude control under tight mass, volume, and power.

Momentum-exchange actuators are the standard propellant-free solution:

• Reaction wheels: precise, but low torque authority
• CMGs: high torque, but singularity-prone
• VSCMGs: variable wheel speed and gimbal angle → high torque, added DOFs for singularity avoidance, dual RW/CMG operation

The gap: VSCMG research has focused on 4-unit pyramid clusters, whose redundancy costs actuator count, volume, and power — resources SmallSats can least afford. The minimum cluster size for practical three-axis control is not well established.

Tbearr: Tardigrade Bio-Exploration Reproduction Research Payload, Chloe Nissen, Jameson Feeley, Kylie Nager, Wilmar Galvez Alfonso, Amber Paul, Sean Crouse, Larry Fineberg, Francisco Crespo Cutillas

Small Satellite Conference

The mission aims to design and build an external ISS payload module investigating the reproductive response of Hypsibius exemplaris (tardigrades) to prolonged radiation in Low Earth Orbit. Experimental success will be measured by population density, as well as analysis of glutathione (GSH) and glutathione disulfide (GSSG, counterpart to GSH) via spectrophotometric assays. This will determine the amount of reactive oxygen species (compounds that cause cellular damage, ROS) generated, and how much of it was neutralized. In-orbit experimentation data, through post-mission experimentation, will be analyzed through on-board or astronaut post-processing and testing procedures. This will provide insight into the mechanisms behind …

The Effects Of Space On Pharmacology And Traditional Medicine: A Review Of Current Literature And Its Potential Impacts On Space Therapeutics, Pratyush Majumdar

Small Satellite Conference

Astronauts in space commonly take medicine for sleep disorders, muscle aches, and other miscellaneous conditions. These medications are taken under the assumption that they will work in space comparable to their effect on Earth, but mounting evidence is emerging to demonstrate that this is not the case. Using the principles of pharmacokinetics and pharmacodynamics, there are many physiological changes that alter how a drug is processed, changing their therapeutic effect. As mission times get longer, there is a heavier need to understand these changes and compensate for them in order to keep astronauts safe.

Ice Giant Watch Dog: Cubesat Concept To Monitor Weather On Neptune, Isabela Huckabee, Don Banfield, Nikole Lewis, Elijah Mullens, Abby Boehm

Small Satellite Conference

Why Neptune?

Neptune hosts one of the most dynamic weather systems in the solar system, yet it hasn't been closely observed since the Voyager-2 flyby. Existing observing programs [1,2] are too infrequent to capture the day-to-week timescales on which storms and clouds evolve, but a dedicated CubeSat could fill this gap.

The current project has two goals:

1. Explore the photometric precisions achievable by a CubeSat platform
2. Determine whether the presence of clouds will be detectable by a CubeSat platform

2020-Current year OA Pubs

As molecular and cellular technologies have advanced, the need to analyze and interpret the resulting vast and multi-modal data into actionable intelligence has become a rate-limiting factor in scientific advancement. While traditional knowledgebase-pathway tools and LLM-based AI tools provide a degree of support in data interpretation, both exhibit known limitations. Presented here is the CompBio multi-omic analysis platform built upon Memory-based Intelligent Reasoning System (MIRaS), an associative reasoning engine grounded in episodic and semantic memory, capable of inferring biological relationships directly from stored knowledge rather than from model training. The MIRaS system is not dependent on human-curated pathway knowledgebases, provides …

Sierasat: A 6u Cubesat Platform For Space-Based Solar Power, Sutharsan Indrakumar, Ahmed Guller, Leann Cwieka, Justin Parry, Minh Nguyen, Kaegan Lucas, Carson Bove, Chaitra Nulu, Myles Thomas, Sophia Jones, Deepak R. Mishra

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 …

Development Of A Digital Electronic Framework To Manage High Power Systems In Small Satellite Missions, Mariel Serra, Rami Kandela, Bryan Johnston-Lemke, Robert E. Zee

Small Satellite Conference

• As small spacecraft payloads increase in complexity, they introduce the need for higher capacity and reliable power systems.
• The use of radiation tested automotive-grade components offer low-costs, however these parts are less suited to increased power demands, exhibiting signs of on-orbit latch-up.
• A re-design of a Modular Power System’s digital framework is proposed to support more spacecraft loads with minimal computational stress on the electronic processing units.

Distributed Avionics As A Foundational Architecture For Cubesat Constellations And Swarms, Aaron S. Swagei, Ali Guarneros-Luna

Small Satellite Conference

Motivation

CubeSat constellations and swarms require spacecraft that can tolerate subsystem faults without relying exclusively on a single centralized flight computer. Distributing sensing, control, and fault-management authority can improve containment and enable graceful degradation.

Objective

Develop and experimentally evaluate a distributed CubeSat avionics architecture in which subsystem nodes retain local fault-management authority while an F´-based OBC provides mission-level coordination.

The FlatSat is used as a representative spacecraft-level building block for future constellation and swarm architectures.

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.

Trade Measures—Relationships And Implications, Peijie Wang, Zhiyuan Liu

Plymouth Business School

Various value-added trade measures have been developed to address the concern in the growing volume of trade in intermediates that are double counted when crossing international borders more than once. This paper raises a query and makes an inquiry into the query. How trade figures in these measures would look like if comparisons are made in net terms and in the context of trading with the rest of the world, given that some double counted elements offset themselves in a series of crossing border processes in opposite traffic? Examined among them in this study are domestic value added in gross …

Helio: Ai Solar Weather Forecasting For Proactive Small Satellite Constellation Response, Kylie Nager, James Kirk, Cagri Kilic

Small Satellite Conference

Challenge:

Small satellite constellations in Low Earth Orbit (LEO) operate in an environment directly exposed to space weather while providing communications, remote sensing, positioning, and other critical services. Geomagnetic storms heat and expand the thermosphere, increasing neutral density, atmospheric drag, and orbital decay. These effects are especially hazardous during post-deployment and orbit-raising operations when satellites remain at low altitude with limited propulsion and recovery margins.

Operational Gap:

NOAA Space Weather Prediction Center products provide essential situational awareness, but satellite operators must still translate environmental forecasts into spacecraft-specific decisions. This translation can introduce operational delay particularly when protective actions must be …
