Planetary Science Virtual Observatory: VESPA/Europlanet outcome and prospects

The Europlanet-2020 programme, which ended Aug 2019, included an activity called VESPA (Virtual European Solar and Planetary Access) which focused on adapting Virtual Observatory (VO) techniques to handle Planetary Science data. We will present some aspects of VESPA at the end of this 4-years development phase and at the onset of the newly selected Europlanet-2024 programme in Feb 2020. VESPA currently distributes 54 data services which are searchable according to observing conditions and encompass a wide scope including surfaces, atmospheres, magnetospheres and planetary plasmas, small bodies, heliophysics, exoplanets, and lab spectroscopy. Versatile online visualization tools have been adapted for Planetary Science, and efforts were made to connect the Astronomy VO with related environments, e.g., GIS for planetary surfaces. The new programme will broaden and secure the former "data stewardship" concept, providing a handy solution to Open Science challenges in our community. It will also move towards a new concept of "enabling data analysis": a run-on-demand platform will be adapted from another H2020 programme in Astronomy (ESCAPE); VESPA services will be made ready to use for Machine Learning and geological mapping activities, and will also host selected results from such analyses. More tutorials and practical use cases will be made available to facilitate access to the VESPA infrastructure.VESPA portal: http://vespa.obspm.frThe Europlanet 2020/2024 Research Infrastructure projects have received funding from the European Union's Horizon 2020 research and innovation programme under grant agreements No 654208 and No 871149
