CASSIOPE: Observing space weather with a hybrid satellite
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
The ePOP probe observes the Earth's ionosphere, where space meets the upper atmosphere; ePOP comprises a suite of eight scientific instruments, including plasma imagers, radio wave receivers, magnetometers and cameras. These are collecting data about the effects of solar storms and, more specifically, their harmful impact on radio communications, satellite navigation and other space and ground-based technologies.

The communications technology demonstrator payload, entitled Cascade, serves as the second mission payload. Cascade is providing a 'proof of concept' design for a high volume store-and-forward data communications operational concept.
Like a courier in the sky, Cascade's operational concept is to pick up very large digital data files and deliver them to almost any destination in the world.

Small and versatile
CASSIOPE's hexagonal Smallsat bus platform measures only 180 cm long and 125 cm high.
It is more cost effective to construct and launch several small satellites with different goals than combining all the functionality on one big satellite. In addition to reducing the risk, this means that the satellites achieve their scientific or commercial objectives at a more reasonable cost.
The new platform produced for the CASSIOPE mission is also versatile: it is possible to adapt and use it for various missions involving science, technology, Earth observation, geologic exploration and information delivery.
Professor Andrew Yau of the University of Calgary directs the ePOP project and a team comprised of researchers and engineers from seven Canadian universities. The Communications Research Centre, located in Ottawa, as well as the Institute of Space and Astronautical Science of Japan and the U.S. Naval Research Laboratory are also partners in the project.
Moreover, CASSIOPE benefits from a solid partnership between the private and public sectors. Spearheaded by MacDonald, Dettwiler and Associates Ltd. (MDA), industry involvement has included Magellan and ComDEV. Vancouver's MDA serves as the mission prime contractor and is leading mission operations with the University of Calgary for a period of 18 months.
