Nebulous: Applying Genetic Algorithms To Design Next-Generation Satellites For Drag Resilience, Rick Marcusen, Adrian Bryant, Julie Rolla, Max Foreback, Evan Imata, Emily Dolson, Kyle Helson, Marcin Pilinski, Anselmo C. Pontes, Jonathan Sy, Joey Wagner, Scott Palo

Small Satellite Conference

Very Low Earth Orbit (VLEO) is a region of space between ~150-400 km that is becoming increasingly valuable for operators of large satellite constellations. VLEO's proximity to the Earth enables improved technical performance, such as higher surface image resolution and lower communications latency, as well as less expensive and more frequent launch opportunities. However, one significant disadvantage to operating in VLEO is the increased effects of aerodynamic drag, which can reduce a mission's lifetime and decrease a spacecraft's position accuracy. To address this, we introduce NEBULOUS, a genetic algorithm-based design tool that evolves spacecraft geometries through generations of mutation and …

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 …

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.

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
