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 …

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 …
