FutureEO

FutureEO (formerly Living Planet Programme) is a Programme of the European Space Agency (ESA) managed by the Earth Observation Programmes Directorate. FutureEO supports preparation and development of series of Earth observation satellite missions including the established Earth Explorers, the smaller agile Scout missions, as well as CubeSat-type Φ-sats.

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. SKIM – a mission to measure ocean-surface currents using the Doppler technique, in order to improve understanding of the ocean current dynamics behind the hydrological and geochemical cycles. Competed with FORUM for the Earth Explorer 9 mission opportunity. Daedalus – a mission to study the electrodynamic processes of the Earth's thermosphere and ionosphere. Competed with Harmony for the Earth Explorer 10 mission opportunity. 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. Competed with Harmony for the Earth Explorer 10 mission opportunity. Cairt (Changing-Atmosphere Infra-Red Tomography Explorer) – a mission to observe atmospheric chemistry and dynamics in the altitude range of 5 to 120 km, in order to better understand the relationship between climate change and atmospheric circulation. Competed with Wivern for the Earth Explorer 11 mission opportunity. Nitrosat – a mission to precisely measure nitrogen dioxide and ammonia levels in the atmosphere, which is essential to understanding the role of nitrogen compounds in aerosol pollution. Competed with Wivern for the Earth Explorer 11 mission opportunity. Seastar – a mission to study sub-mesoscale meteorological dynamics by providing 1 km resolution ocean surface current and wind vectors for coast, shelf, and polar ice zones. Competed with Wivern for the Earth Explorer 11 mission opportunity. ===Earth Explorer 12 candidates=== From the 17 submissions, ESA’s Advisory Committee for Earth Observation (ACEO) recommended that four of the ideas should go forward to the assessment study phase: CryoRad proposes to measure low frequency passive microwave radiometry of the cryosphere. ECO would directly measure the difference between incoming solar radiation and outgoing radiation of the planet. Hydroterra+ is a geostationary satellite mission to provide high temporal rate SAR imagery to understand rapid water cycle and tectonic events. Keystone would measure atomic oxygen in 50–100 km of the atmosphere. On 25 September 2026, ESA's Programme Board for Earth Observation selected ECO, Keystone, and CryoRad to progress to the next preparatory phase. ==References==
