A Space Weather Research Satellite Payload


The University of Calgary is leading the operation of the Enhanced Polar Outflow Probe (e-POP), a scientific payload for CASSIOPE, the first, made-in-Canada multi-purpose small satellite mission from the Canadian Space Agency.

The e-POP payload is aboard the CASSIOPE satellite in an elliptical polar orbit, circling the globe at altitudes between 325 and 1500 km. Launched on September 29, 2013, e-POP's eight scientific instruments are collecting new data on space storms and associated plasma outflows in the upper atmosphere and their potentially devastating impacts on radio communications, GPS navigation, and other space-based technologies. » Read more...
