Deal signed for FLEX's fluorescence finder: link

Quote
ESA has selected Italian company Leonardo to build the main instrument for the upcoming FLEX satellite to study the health of Earth’s vegetation.

At an event held today in Florence, Italy, Leonardo signed a €74 million contract to design, build and test the spectrometer for ESA’s eighth Earth Explorer over the next four years.

Planned for launch by 2022, it will detect and measure the light emitted by plants as they convert sunlight and the atmosphere’s carbon dioxide into energy.

Reissued: call for Earth Explorer 9 proposals

Quote
So far, eight missions have been selected for implementation. Each was proposed by the scientific community and realised through a user-driven selection process to ensure that each missions address key Earth-science questions.

As part of this process, ESA released a call for proposals for the ninth Earth Explorer in November 2015. However, in this case, none of the proposals met the boundary conditions as stated in the call. As a result, ESA has updated some conditions and has reissued the call.

Proposals should not only demonstrate scientific excellence and innovative technology, but also address important questions that have a direct bearing on societal issues we are likely to face in the coming decades. This includes, for example, the availability of food, water, energy and resources, health, risk of disaster and climate change.

It is expected that the selected mission will be launched by 2025

Call for new Earth Explorer mission ideas

Quote
As part of ESA’s commitment to realise new satellite missions that advance our understanding of Earth, benefit society and demonstrate innovative space technologies, a call is now open for new Earth Explorer ideas.

Released today, the call invites scientists working in Earth observation to submit ideas for ESA’s 10th Earth Explorer mission

Quote
ESA foresees the 10th Earth Explorer being launched in 2027–28. The procedure for submitting an initial idea for this future mission begins with a letter of intent, which must be received by 15 December 2017.

Two new Earth Explorer concepts to understand our rapidly changing world (EE09)

Quote
ESA has chosen two concepts, FORUM and SKIM, to be developed further and compete to be the ninth Earth Explorer mission.

Quote
Thanks to new technical developments, the Far-infrared Outgoing Radiation Understanding and Monitoring (FORUM) candidate would measure radiation emitted from Earth across the entire far-infrared part of the electromagnetic spectrum. Significantly, it measures in the 15–100 micron range, which has never been done from space before.

Quote
FORUM’s benchmark measurements would improve our understanding of the greenhouse effect and, importantly, contribute to the accuracy of climate change assessments that form the basis for policy decisions.

The Sea-surface Kinematics Multiscale monitoring (SKIM) candidate would carry a novel wide-swath scanning multibeam radar altimeter to measure ocean-surface currents. Uniquely, it uses a Doppler technique, which offers more direct measurements than conventional satellite altimeters.

Quote
“With this recommendation now accepted, these two candidates will spend the next two years being studied thoroughly. In 2019, a User Consultation Meeting will be held, after which a decision will be taken by ESA’s Member States as to which of the two contenders will be implemented.

“We foresee Earth Explorer 9 being launched in 2025.”

Three Earth Explorer ideas selected (EE10)

Quote
As part of ESA’s continuing commitment to realise cutting-edge satellite missions to advance scientific understanding of our planet and to show how new technologies can be used in space, three new ideas have been chosen to compete as the tenth Earth Explorer mission.

The decision follows the release of a call for ideas in September 2017. Out of the 21 proposals submitted, ESA’s Advisory Committee for Earth Observation (ACEO) recommended that three mission ideas should be selected for feasibility study: Stereoid, Daedalus and G-Class.

Today, ESA’s Programme Board for Earth Observation accepted the committee’s recommendation.

Quote
Stereoid would orbit in formation with one of the Copernicus Sentinel-1 satellites. Carrying a synthetic aperture radar, it aims to measure small shifts in the ocean surface, in glaciers and in Earth’s surface. This would improve our understanding of small-scale ocean circulation patterns, advance knowledge of glacial dynamics and their contribution to sea-level rise, and measure changes in land-surface topography.

Daedalus would carry a suite of instruments to provide measurements in a largely unexplored area between the Earth’s upper atmosphere and space. Here, intriguing and complex processes govern the deposition, transformation and transport of some of the Sun and solar wind’s energy. The aim is to quantify amounts of energy deposited in the upper atmosphere by measuring, for example, effects caused by the electrodynamic processes in this region. The concept is based on a mother satellite, which carries a suite of instruments along with four small satellites carrying a subset of instruments that are released into the atmosphere.

G-Class would carry a synthetic aperture radar and would be rather uniquely placed in a geosynchronous orbit to provide a constant view of Africa and the Mediterranean regions. The mission aims to make observations of diurnal water cycle processes to improve the prediction capability for rainfall, water availability, flooding and landslides.

Feasibility studies will now start, after which a further selection will be made, with a view to launching of the successful mission in 2027–28.
