An exploratory Call for a new type of agile mission in the ESA Science Programme – mini-Fast missions – will be issued on 19 March 2025. The purpose of this Call is to probe the interest in and feasibility of mini-Fast missions, which could address science objectives implementable in a period of less than five years (from Phase 0 to launch). Such missions could benefit the Science Programme by allowing higher involvement and visibility for many Member States, opening opportunities for new communities, increasing the cadence of missions, and investigating new implementation schemes. Preliminary information concerning this exploratory Call can be found in the recording of the briefing meeting held on 11 December, the presentation files, and the Q&A from the meeting, which are available online.
