1: Call for a Medium-size and a Fast mission opportunity in ESA's Science Programme

The ESA Director of Science solicits the scientific community in ESA's Member States for proposals for both a "Fast" mission opportunity (to be launched in the 2030-2031 timeframe) and for a Medium mission opportunity (to be launched around 2037).  The new long-term scientific plan - Voyage 2050 - for the Science Programme of the European Space Agency (ESA), has been issued in June 2021, following a broad consultation of the scientific community and a peer review process, with final recommendations issued by an independent scientific Senior Committee. The plan includes three Large (L) missions in selected science themes (Moons of the Giant Planets, From Temperate Exoplanets to the Milky Way, and New Physical Probes of the Early Universe) and a set of Medium (M) and Fast (F) missions. The definition of the F and M space missions is based on a competitive, peer-reviewed selection process. Even though the Voyage 2050 plan identifies a set of possible themes for the Medium missions, proposals in all fields of space science will be considered, with no prejudice.

2: Call for Membership in the Expert Committee for the Large mission covering the science theme “Moons of the Giant Planets”

The Director of Science at the European Space Agency (ESA) has issued a Call for Membership in the Expert Committee for the Large mission covering the science theme “Moons of the Giant Planets” that will support the initial definition of space mission concepts to fulfil the goals set for the “Moons of the Giant Planets” science theme.  This is the first scientific theme identified in the new long-term scientific plan (Voyage 2050) for the ESA Science Programme for the large mission following Athena and LISA. “Moons of the Giant Planets” addresses issues such as habitability, biosignatures, prebiotic chemistry, etc., to be implemented through a planetary probe to one of the moons of either Jupiter or Saturn.

Deadline for receipt of applications is 18 January 2022

I would be grateful if you could bring these two Calls to the attention of the Spanish space science community. I'm happy to answer any questions you may have about these.
