Editing CASSIOPE (section)

==Operations==
After a successful launch on September 29, 2013, CASSIOPE entered into a commissioning phase that lasted to January 1, 2014, with no faults detected on the spacecraft bus or payloads. Three ground stations were utilized, including Kiruna (Sweden), Inuvik (Canada), and the German Antarctic Receiving Station at the General Bernardo O'Higgins Base in Antarctica. Routine operations were scheduled to run to March, 2015. The mission was extended via funding from the Technology Partnerships Canada program through the Industrial Technologies Office that was part of the Canadian government at the time. In February 2018, the [[European Space Agency]], through the [https://earth.esa.int/web/guest/missions/3rd-party-missions/overview;jsessionid=2FB361765B7C12E7D448DDF553603794.jvm2 Third Party Mission Program]{{Dead link|date=August 2023 |bot=InternetArchiveBot |fix-attempted=yes }}, integrated the mission into the Swarm constellation of satellites, dubbing CASSIOPE "Swarm-Echo", recognizing the synergy between the two missions in collecting space weather data in low Earth orbit. 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.

On August 11, 2016, one of the four reaction wheels used for spacecraft attitude control failed. This did not affect spacecraft operations in a significant way since only three wheels are required for 3-axis stabilized pointing. A second reaction wheel failed on February 27, 2021, forcing the spacecraft into a slowly spinning, safe-hold attitude configuration. Three-axis stabilized control was restored in September 2021 by implementing a bias momentum configuration on the two remaining wheels (spinning the wheels in opposite directions), and using the magnetic torque rods for attitude control. Three months later, on December 17, 2021, a third reaction wheel failed, leaving the spacecraft with no viable methods for fixed attitude pointing. Although most of the e-POP instruments were fully operational, without stabilized pointing much of the science objectives could not be met, resulting in a conclusion of the operational portion of the mission on December 31, 2021.<ref name=ucalgary-2022/>
