Heaviest satellite launched by European Space Agency (ESA) into space at 1,367 kg
A government satellite, Aeolus is operated by European Space Agency (ESA) of ESA for the purpose of earth observation (Earth Science).
A LEO satellite, it was launched into space using Vega as the launch vehicle from Guiana Space Center on 22 August 2018. Aeolus was constructed by Airbus Defense and Space (France/UK/Germany/Spain).
Designed with an operational lifetime of 3 years, Aeolus has a launch mass of 1,367 kg and navigates with the COSPAR ID 2018-066A and NORAD ID 43600.
Taking 92 minutes to orbit the Earth, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 314km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 317km. The eccentricity of the orbit is 2.24E-04 and it orbits at an inclination of 97 degrees to the equatorial plane of the Earth.
