=== Fast class === At the ESA Science Programme Committee (SPC) Workshop on 16 May 2018, the creation of a series of special opportunity Fast class (F-class) missions was proposed. These F-missions would be jointly launched alongside each M-class mission starting from M4, and would focus on "innovative implementation" in order to broaden the range of scientific topics covered by the mission. The inclusion of F-class missions into the Cosmic Vision program would require a significant increase of the science budget, to be discussed in future meetings. Two F-class missions have been selected:
F1, Comet Interceptor, a mission to study a long-period comet or an interstellar object (which will be determined after the launch), launching as a secondary payload together with M4, ARIEL in 2029. F2, ARRAKIHS (Analysis of Resolved Remnants of Accreted galaxies as a Key Instrument for Halo Surveys), a mission to survey one hundred nearby galaxies and their surroundings to investigate the development of dwarf galaxies and stellar streams; launch planned for the early 2030s.
=== Timeline ===
== Missions of opportunity == Occasionally ESA makes contributions to space missions led by another space agency. These missions include:
Hinode – X-ray space telescope leading by JAXA, launched in 2006 IRIS – solar space spectrograph leading by NASA, launched in 2013 Microscope – microsatellite for studying free fall leading by CNES, active in 2016–2018 XRISM – X-ray space telescope leading by JAXA, launched in 2023 ExoMars – a series of Mars probes in collaboration with Roscosmos, an orbiter operational since 2017, a rover to be launched in late 2020s Einstein Probe – a space mission dedicated to time-domain high-energy astrophysics leading by Chinese Academy of Sciences, launched in 2024 PROBA-3 – space technology testing spacecraft, launched in 2024 MMX – a sample-return Mars' moons probe leading by JAXA, to be launched in 2026 Nancy Grace Roman Space Telescope – a space telescope led by NASA, to be launched in 2027 A contribution to SPICA (Space Infrared Telescope for Cosmology and Astrophysics), a Japanese mission was evaluated as a mission of opportunity within the Cosmic Vision, but is no longer considered within that framework. It was one of the finalists being considered for M5.
