Auroral Reconstruction CubeSwarm – ARCS: a Heliophysics mission concept for decoding the aurora 

Kristina A. Lynch, Dartmouth College of Physics and Astronomy 

The ARCS mission goal is to decode the aurora by exploring the relationship between the visible aurora and distributed currents and flow fields, to unlock critical physics of the auroral ionosphere at mesoscales. The ARCS swarm produces low-resource observations for system science enabling progress toward the “Diversified and Distributed Sensor Deployment Strategy” envisioned in the NAS Decadal Appendix C. 32 satellites in 8 planes with repeat ground tracks will cross over 32 ground-based observatory sites in Alaska. The orbits are sun-synchronous at 561 km altitude and 97 degree inclination. The 32 GBO sites contain filtered imagery for the creation of maps of precipitation average energy and energy flux; they also contain transmitters for a local TEC network, to work with receivers on the spacecraft. 

The ARCS science objectives are: (1) map the 2D mesoscale structure and temporal evolution of plasma flows and currents in the auroral iononosphere; (2) determine how these 2D maps of plasma flows and currents self-consistently evolve in conjunction with auroral ionospheric density responses; (3) determine the roles of the physical mechanisms regulating the relationships between the flows, currents, auroral forms and precipitation in the auroral ionospheric system.
