CASSIOPE is a multifunctional mission designed to serve both a scientific and a demonstration of technology purpose.
The small satellite measures 1.8 m in diameter x 1.4 m high and weighs 481 kg. It will fly in a slightly elliptical orbit that
goes back and forth, over the Equator, from the North to the South Polar Regions.
The science payload of CASSIOPE, called the enhanced Polar Outflow Probe, or e-POP, will be Canada’s first space
environment sensor suite, consisting of eight instruments, including plasma sensors, radio wave receivers,

Falcon 9 will deliver three secondary payloads to orbit as part of the CASSIOPE mission:
• POPACS (Polar Orbiting Passive Atmospheric Calibration Spheres): A privately funded CubeSat mission to
measure the effects of solar flares and coronal mass ejections on the density of Earth’s upper atmosphere 5
during solar cycles 24 and 25. POPACS is a mission by collaboration between Utah State University, Gil Moore,
Planetary Systems Corporation and Drexel University.
• DANDE (Drag & Atmospheric Neutral Density Explorer): A 50 kg spherical spacecraft developed by students at
