The Enhanced Polar Outflow Probe (e-POP) is a research payload on the CASSIOPE spacecraft that is collecting new data on space storms and associated plasma outflows from the Earth's ionosphere.



Launched on September 29, 2013 by a SpaceX Falcon 9 rocket, e-POP is enabling scientists to study space weather and its potentially devastating impacts on radio communications, GPS navigation, and other space-based technologies.



The University of Calgary is leading the operation of e-POP, which is the first made-in-Canada multi-purpose small satellite mission from the Canadian Space Agency. Cassiope is now funded by European Space Agency as part of the Swarm constellation of satellites.
