The successfully completed GOCE mission mapped variations in Earth’s gravity with extreme detail and accuracy. Presently there are four missions in operation: CryoSat, SMOS, Swarm and Aeolus, which are providing new insight into Earth’s cryosphere, soil moisture and ocean salinity, the magnetic field and atmospheric circulation, respectively.
Four missions currently being built: EarthCARE to provide information on the effect of clouds and aerosols on Earth’s radiation budget, Biomass to measure forest carbon, FLEX to study plant photosynthesis and FORUM to understand the infrared energy emitted by Earth.
In addition, three candidates for Earth Explorer 10 are currently being studied, and four Scout candidate missions are undergoing system consolidation studies.
To add to this family of extraordinary satellite missions, it is now time to start the process of realising the eleventh Earth Explorer, which is foreseen to be launched in 2031–2032.
Upon the official release of the Call on Monday 25 May, the procedure for submitting an initial idea for this future mission begins with a letter of intent, which must be received by 18 September 2020. This will be followed with a workshop with Proposers on 5 October 2020 to explain the proposal guidelines.
The deadline for submitting the final proposal is 4 December 2020 at noon European time.
More information about the Call and how to submit letters of intent can be found at ESA’s Earth Observation Proposal System.
