Virtual European Solar & Planetary Access (VESPA) 2023: Strengthening

VESPA focuses on adapting Virtual Observatory (VO) techniques to Planetary Science data. The objective is to build a contributory distribution system to easily access and publish data. This activity is held in the EC-funded Europlanet-2024-RI program. Progress during the 3rd year of the program are reported here.

Data access. VESPA has defined a specific metadata vocabulary providing uniform description of datasets in the field. In 2022, this EPN-TAP protocol has been approved by the International Virtual Observatory Alliance, and is now the standard to publish Solar System data in the VO.

The VESPA portal is a discovery tool to browse the EPN-TAP services. Other access modes are available: scripts, web services, Jupyter notebook, VO tools, etc. Some existing VO tools (TOPCAT, Aladin, CASSIS) are being adapted to these data.

Data services. 63 EPN-TAP data services are currently searchable from the VESPA portal. Contributions from space agencies include ESA’s PSA, and ~ 100 datasets from the NASA PDS PPI node (under review). Data infrastructures with EPN-TAP interface (AMDA for planetary plasmas, SSHADE for solid phase spectroscopy, PVOL for amateur images) also develop their content and capacities. Contributions from the community are solicited via an annual call and implementation workshop – one was held in June 2023, and one more workshop is scheduled in the course of the program.

Service implementation support and sustainability. A standard workflow to develop and deploy data services has been finalized, relying on a flexible Docker installation of DaCHS and use of a common Gitlab repository (with authentication granted by GÉANT/eduTEAMS).

Coming data services. VESPA standards and infrastructure are available to distribute data from the community, in particular to help publicly funded programs fulfill Open Science commitments. A PDS4 dictionary for EPN-TAP is being finalized, which will also provide a data handling and distribution system to nanosat missions.

The Europlanet-2024 Research Infrastructure project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreements No 871149.
