The Living Planet Programme (LPP) [1] 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[edit]

Selected missions[edit]

Currently there are eight approved Earth Explorer missions, five of which are in orbit and operating:

  • GOCE – Gravity Field and Steady-State Ocean Circulation Explorer; it was launched on 17 March 2009.[2]
  • SMOS – Soil Moisture and Ocean Salinity satellite[3][4] will study ocean salinity and soil moisture; it was launched on 2 November 2009.[5]
  • 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.
    • CryoSat-2 was launched on 8 April 2010.
  • Swarm – a trio of satellites to map the Earth's magnetic field.[6] The SWARM constellation was launched successfully on 22 November 2013.[7]
  • Aeolus – the Atmospheric Dynamics Mission Aeolus uses an innovative laser to measure global winds. Aeolus was successfully launched on 22 August 2018.[8][9]
  • EarthCARE – Earth Clouds Aerosols and Radiation Explorer will examine the formation and effects of clouds.[10] Due for launch in 2021.[11]
  • Biomass (satellite) [fr] – 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 2021.[12][13]
  • FLEX – the FLuorescence EXplorer mission will globally monitor steady-state chlorophyll fluorescence in terrestrial vegetation.[14] It is envisaged to launch in 2023.[15]

Candidate missions[edit]

There are two ongoing competitions for the Earth Explorer 9 and Earth Explorer 10 missions.[16][17]

Earth Explorer 9 Candidates[edit]

The winning candidate is currently projected to launch in 2025.[16]

Earth Explorer 10 Candidates[edit]

The winning candidate is currently projected to launch in 2027 or 2028.[17]

Non-selected missions[edit]

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.[19] 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.[20] 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.[21] Competed with FLEX for the Earth Explorer 8 mission opportunity.
