Project: Space Weather Atmospheric Reconfigurable Multiscale Experiment (SWARM-EX)
The Space Weather Atmospheric Reconfigurable Multiscale Experiment (SWARM-EX) is a National Science Foundation (NSF) sponsored CubeSat mission distributed across six colleges and universities in the United States. The project has three primary goals:
- Contributing to aeronomy and space weather knowledge.
- Demonstrating novel engineering technology.
- Advancing higher education.
The scientific focus of SWARM-EX is to study the spatial and temporal variability of ion-neutral interactions in the equatorial Ionosphere-Thermosphere (I-T) region. Since the mission consists of three spacecraft operating in a swarm, SWARM-EX will take in-situ measurements of the neutral and ion composition on timescales of less than an orbital period to study the persistence and correlation between different phenomena in the I-T region. The engineering objectives of SWARM-EX are focused on advancing the state of the art in spacecraft formation flying. In addition to being the first passively safe, autonomous formation of more than two spacecraft, SWARM-EX will demonstrate several other key innovations contributed by SLAB, such as a novel Guidance, Navigation and Control algorithm that exploits a hybrid propulsive and differential drag control scheme for fuel-efficient formation control, thus enabling the realization of a distributed aeronomy sensor efficiently.
