The ESA’s EarthCARE Satellite to Be Launched by Arianespace
(MSI) and a Broad-Band Radiometer (BBR), plus the Launcher
and Ground Segment (with exception of the CPR data segment).
The EarthCARE mission will use a Soyuz launch vehicle, with
the launch period starting in June 2022 from the Guiana Space
Center, Europe’s Spaceport in French Guiana (South America).
The satellite will have a mass at liftoff of approximately 2,350
kg and will circle Earth in SSO, crossing the equator in the early
afternoon to optimize daylight conditions, at an altitude of 390
km. The altitude needs to be as low as possible to optimize use of
both the lidar and radar, but not too low where atmospheric drag
would impact fuel consumption and the lifetime of the mission.
EarthCARE has a design lifetime of three years, including a six-
month commissioning phase. The mission’s goal is to provide a
picture of the 3D-dimensional spatial and the temporal structure
