In March 2007 a call for mission ideas was formally released, which yielded in 19 astrophysics, 12 fundamental physics and 19 solar system mission proposals.

Medium-size missions (M)

M-class projects will usually be relatively stand-alone ESA projects. The two first M-class missions, M1 and M2, have been selected:
  • M1, Solar Orbiter

The third M-class mission, M3, is planned for launch in 2022. ESA released a call for missions proposals for M3 in July 2010.
On February, 25, 2011, ESA announced the selection of four missions to undergo an initial assessment phase. In addition, Plato

Large missions (L)

L-class projects will often be carried out in collaboration with other partners and should have an ESA cost not exceeding 900 million euros. The first large mission, L1, is planned for launch in 2020. There are currently three candidates for L1:
  • Europa Jupiter System Mission
    Europa Jupiter System Mission
    The Europa Jupiter System Mission – Laplace was a proposed joint NASA/ESA unmanned space mission slated to launch around 2020 for the in-depth exploration of Jupiter's moons with a focus on Europa, Ganymede and Jupiter's magnetosphere...

The process for selection of one of the candidates for implementation as L1 started in October 2010.

In April 2011 it became clear that budget pressures in the US meant that the expected NASA collaboration would not be practical; so the down-selection was delayed and the missions re-scoped on the assumption of ESA lead and some limited international participation
