The European Electric Propulsion Database is funded by ESA and free of charge. Free access will only depend on the affiliation to an entity based in an ESA member state.
It consists of two core elements:
The Hardware Database is managed and updated by ESA. The community can review it and report any erroneous data, as well as suggest to include or remove data.
The Plume Database is a platform meant to simplify the exchange of data within the community. Every user is able to share data that will be available for the rest of the community and can be used for comparison of thruster characteristics, input for simulations or other purposes.
In addition, a large amount of plume data has been digitalized within the AISEPS project. This data can be found in the database, but will be available for download only after the authors have reviewed and released it.
