Second heaviest elliptical satellite launched into space at 490 kg
Operated by Canadian Space Agency of Canada, Cassiope is a government satellite launched for the purpose of earth science.
Constructed by Canadian Space Agency (Canada), it was launched into space using Falcon 9 as the launch vehicle from Vandenberg AFB on 29 September 2013. Cassiope orbits around the Earth as a elliptical LEO satellite.
Cassiope has a launch mass of 490 kg and is expected to have a operational lifetime of 2 years. It navigates with the COSPAR ID 2013-055A and NORAD ID 39265.
Using its self-produced usable power of 600 watts, Cassiope orbits at an inclination of 81 degrees to the equatorial plane of the Earth.
The satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 325km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 1,486km. Its orbit has an eccentricity of 7.98E-02 and it takes 103 minutes to orbit the Earth.
