quote: With the launch of the hybrid small satellite CASSIOPE, Canada is making a significant contribution to unraveling the mysteries of space weather. To accomplish this feat, the satellite uses a dedicated scientific payload ePOP (enhanced polar outflow probe), which observes the ionosphere.

In addition, two technological advancements are supported by the mission:

A new Smallsat spacecraft Bus
A communications technology demonstrator, Cascade
