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.

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)

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 …

Development Of A Design Tool For 3d-Printable Cold Gas Thruster Systems For Nanosatellite Missions, Mikolaj Szyszka, Katherine Smith

Small Satellite Conference

Currently, there are 5219 Nanosatellites and CubeSats in orbit [1]. A decade ago, this number was only 800 [1], with forecasts predicting a total of 14,000 small satellites in orbit by 2033 [2]. However, out of the ones that are currently operational, only about 5% are equipped with a propulsion system. Omitting the electric and classified thrusters, cold gas systems are the most popular due to their simplicity and ease of operation. This shows a general lack of manoeuvrability and agility within small satellites in orbit. The proposed C.O.N.E tool aims to bridge the gap between nanosatellite manufacturers and simple …

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.

Small Satellite Conference

Alpha CubeSat is a 1U CubeSat designed, built, and operated by a student-led team at Cornell University. Its primary mission is to deploy a free-flying lightsail in low Earth orbit, carrying gram-scale "ChipSat" flight computers as a demonstration of low-cost distributed sensing in space. The spacecraft was built around commercial, off-the-shelf hardware, including a Teensy 3.5 microcontroller as the primary flight computer and a RockBLOCK Iridium modem for communication, and was developed and flown under the constraints that define a student program: a small power budget, a rotating team, limited development time, and an intermittent operations radio link. The CubeSat …

Concept Of Operation Logic And Implementation Expectations For Multimode Propulsion Technology Demonstration Missions, Logan Thompson, Michael Harrigan, Theresa Sandborn, Victoria Coverstone, Joshua L. Rovey

Small Satellite Conference

Traditional single-mode propulsion systems are typically optimized for either high-thrust, short-duration maneuvers (chemical propulsion) or high-efficiency, low-thrust operations (electric propulsion). For CubeSats, which are limited by mass, volume, power, and system complexity, carrying separate propulsion systems for each mission phase is often impractical. Multimode propulsion systems overcome this limitation by combining chemical and electric propulsion within a shared architecture, allowing a single spacecraft to perform both rapid maneuvers and efficient long-duration orbit maintenance.

Demonstrating a multimode propulsion system requires more than operating two propulsion modes on the same spacecraft. Shared propellant, feed systems, thermal interactions, power usage, and transitions …

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 …

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 …

Star-Planet Research CubeSat (SPARCS) is a 6U space telescope dedicated to monitoring flares from low-mass stars in the ultraviolet (UV). SPARCS observations of flares across 20 solar systems will be used to better understand the atmospheric evolution, chemistry, and potential habitability of the most common type of exoplanets. SPARCS’ camera uses delta-doped CCD detectors, which are several times more sensitive in the UV than previous detectors. This is technology necessary for future studies of habitable-worlds and star–planet interactions by future missions, such as NASA’s flagship mission, the Habitable Worlds Observatory. SPARCS orbits in the “6am terminator” orbit, which provides a …

Neutron-2: A Dual Cubesat Mission For Three-Dimensional Mapping Of Neutron Radiation In Low Earth Orbit, Miguel Nunes, Piper Kline, Kenoi Salvador, Peter Englert, William Edmonson, Craig Hardgrove, Erik B. Johnson

Small Satellite Conference

Neutron interactions in Low Earth Orbit (LEO) remain a poorly characterized component of the space radiation environment, despite their potential to significantly impact spacecraft electronics, materials, and crew health. Unlike primary charged particles, most neutrons in LEO are secondary products generated when high-energy protons and heavy ions from galactic cosmic rays or solar energetic particle events interact with atoms and molecules in Earth’s atmosphere. The production rate of these secondary neutrons is strongly dependent on atmospheric density, which varies with altitude, geomagnetic position, and solar activity, leading to spatial and temporal variability that is not well captured by current radiation …

Small Satellite Conference

The Air Force Research Lab’s (AFRL) Small Satellite Portfolio (SSP) created the XVI CubeSat which was launched on SpaceX’s Transporter 8 in June of 2023. 

XVI remained operational from June 2023 until its deorbit on January 7, 2026. Throughout its lifetime, the team maintained the vehicle and used XVI for experimentation and training purposes. However, due to the sun's low activity around this time frame, and intentionally lowering the drag/cross sectional area of XVI on orbit, the spacecraft was able to stay in orbit for months beyond its initial predicted re-entry. 

Between January 4th and January 7th, XVI was tracked …

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 …}
