The Living Planet Programme (LPP)  is a programme within the European Space Agency which is managed by the Earth Observation Programmes Directorate. LPP consists of two classes of Earth observation missions (listed below) including research missions known as Earth Explorers, and the Earth Watch class of missions whose objective is to develop support operational applications such as numerical weather forecasting or resource management.
List of Earth Explorers missions
Currently there are nine approved Earth Explorer missions, four (SMOS, CryoSat-2, SWARM, Aeolus) of which are in orbit and operating:
GOCE – Gravity Field and Steady-State Ocean Circulation Explorer; it was launched on 17 March 2009. It reentered the atmosphere on 11 November 2013.
SMOS – Soil Moisture and Ocean Salinity satellite will study ocean salinity and soil moisture; it was launched on 2 November 2009.
CryoSat – a program designed to map the Earth's ice cover.
CryoSat-1 was lost in 2005 when the Russian SS-19 Rockot launch vehicle malfunctioned and was terminated.
Swarm – a trio of satellites to map the Earth's magnetic field. The SWARM constellation was launched successfully on 22 November 2013.
Aeolus – the Atmospheric Dynamics Mission Aeolus uses an innovative laser to measure global winds. Aeolus was successfully launched on 22 August 2018.
Approved, but yet to launch :
EarthCARE – Earth Clouds Aerosols and Radiation Explorer will examine the formation and effects of clouds. Due to launch in March 2023.
BIOMASS – designed to calculate the amount of carbon stored in the world's forests, and to monitor for any changes over the course of its five-year mission. Due to launch in October 2022.
FLEX – the FLuorescence EXplorer mission will globally monitor steady-state chlorophyll fluorescence in terrestrial vegetation. It is planned to launch in mid-2024.
Hydroterra (formerly known as G-Class) – a geosynchronous synthetic aperture radar satellite that aims to observe diurnal water cycle processes, in order to improve weather prediction capabilities.
The winning candidate is currently projected to launch in 2027 or 2028.
Earth Explorer 11
The competition for the Earth Explorer 11 mission will occur in the early 2020s. A call for proposal ideas was released on 25 May 2020, with the deadline for submission on 4 December 2020. The winning candidate is projected to launch in 2031 or 2032.
Past candidate missions that were not selected include:
CoReH2O – a mission to study key characteristics in terrestrial snow, ice, and water cycles and their relations to climate change and variability. Competed with BIOMASS and PREMIER for the Earth Explorer 7 mission opportunity.
PREMIER – a mission to study atmospheric processes related to trace gas, radiation, and chemical compositions in the mid to upper troposphere and lower stratosphere in order to understand their role on climate change. Competed with BIOMASS and CoReH2O for the Earth Explorer 7 mission opportunity.
CarbonSat – a mission to determine the global distributions of carbon dioxide and methane and their impact on climate change. Competed with FLEX for the Earth Explorer 8 mission opportunity.
