CASSIOPE

Cascade, Smallsat and Ionospheric Polar Explorer (CASSIOPE),[5] is a Canadian Space Agency (CSA) multi-mission satellite operated by the University of Calgary.

Built by MDA, the operational concept is to receive very large data files as the satellite orbits the globe, store them onboard temporarily, then deliver them at a later time to nearly any destination worldwide.

[11] The demonstrator will provide a secure digital store-and-forward file delivery service, exploiting the fact that CASSIOPE passes over much of the globe 15 times per day.

as a courier service, with the customers using a small parabolic antenna of one or two meters (three or six feet) to upload or download files at a rate of 1.2 gigabits per second.

The storage capacity will be between 50 and 500 gigabytes and the data delivery time will be about 90 minutes, depending on the pickup and deposit points on the globe.

The University of Calgary's Institute for Space Research leads the science project, while MDA is the prime contractor for the mission including launch and operation of the spacecraft.

While these atmospheric glows may offer a thrilling night time spectacle, the inducing radiation can interfere with radio communications, GPS navigation, and other space-based systems.

[citation needed] The eight scientific instruments aboard CASSIOPE will help scientists understand solar weather and eventually plan for measures to mitigate its deleterious effects.

The partnership allowed for four ground station contacts per day, rather than one, greatly increasing the amount of data that could be downloaded from the e-POP suite of instruments.

Three months later, on December 17, 2021, a third reaction wheel failed, leaving the spacecraft with no viable methods for fixed attitude pointing.

[13] The satellite that became CASSIOPE began with a 1996 concept for a small (70 kg/150 lb), inexpensive microsatellite called Polar Outflow Probe, or POP.

After the three-minute boost phase of September 29, 2013 launch, the booster stage attitude was reversed, and three of the nine engines refired at high altitude, as planned, to initiate the deceleration and controlled descent trajectory to the surface of the ocean.
