Transnational Access (TA) Call 2026

Transnational Access (TA) Call 2026

Europlanet provides FREE Transnational Access (TA) to planetary simulation and analysis facilities to enable the simulation or characterisation of planetary conditions and materials.

The programme supports mobility and international collaboration. Evaluation of 197 Europlanet Transnational Access visits supported through the Europlanet 2024 Research Infrastructure (RI) programme from 2020-2024 showed that:

  • 91% of TA hosts & visitors planned future research activities together
  • 66% of TA participants reported that their visits led them to consider new research questions or lines of research
  • Over 50% of TA visits were by early careers and provided opportunities that would not otherwise be available to them
  • Over 300 publications are anticipated on the results of the visits.

Sustainable TA through Europlanet

  • Building on over a decade of experience in offering TA through EC-funded programmes, Europlanet provides annual calls for access to facilities.
  • Europlanet’s TA programme supports all travel and local accommodation costs for European and international researchers to visit these facilities.
