CALL FOR A MEDIUM-SIZE AND A FAST MISSION OPPORTUNITY
IN ESA’S SCIENCE PROGRAMME

Step-1 proposal submission form
​​​​for M-class and F-class mission concepts

As described in the Call for a Medium-size and a Fast mission opportunity in ESA's Science Programme document, proposals in response to this Call must be submitted in two steps. Step-1 proposals will be subject to a first technical and scientific screening by ESA (for technical and programmatic feasibility aspects) and by a scientific peer review committee, under the responsibility of the ESA Scientific Advisory Structure, for the scientific goals. Proposers whose Step-1 proposals will have been considered likely to meet the technical feasibility and whose science case will be considered sufficiently competitive by the scientific peer review will be invited to participate in a workshop in anticipation of the Step-2 proposal submission.  Following the workshop, proposers will be invited to submit a Step-2 proposal.

Phase-1 proposals must be submitted using the form below. Only pdf files will be accepted; files must not be locked or protected; the maximum file size accepted is 50 MB. Full details of the format and content for the proposal are given in the Call for a Medium-size and a Fast mission opportunity in ESA's Science Programme document.

Please note that after selecting the file you wish to submit you must wait for an on-screen message indicating that the file has been successfully uploaded before finishing the submission process.

An acknowledgement of receipt will be sent to the proposer at the email address provided, upon successful submission of the proposal.

The deadline for receipt of Step-1 proposals is
​​​​​​​ 21 May 2025, 12:00 (noon) CEST

Late submissions will not be considered. Step-2 proposals that have not been preceded by a Step-1 proposal will not be considered.
