11th European Space Propulsion System Simulation (ESPSS) Workshop

1 Oct 2025, 09:00 → 2 Oct 2025, 19:00 Europe/Amsterdam

Newton 2 Conference Room (ESTEC, The Netherlands)

Johan Steelant (ESA - ESTEC), Leonard Schraven

Following the needs of the European Space Propulsion Community, a first workshop on ESPSS was collocated with the ESA Space Propulsion 2012 Conference at Bordeaux.  Due to its success and on users’ request, ESA-ESTEC responsible for the ESPSS development is now preparing the 11th ESPSS workshop covering the following topics:

• ESPSS 3.10.0 release notes
• ESPSS and EcosimPro roadmaps for 2025 and beyond
• User’s round table
• Requests for new improvements
• ESPSS training

The workshop will be divided into two days.  

During the first day, a general overview of the European Space Propulsion System Simulation will be given by ESA and Empresarios Agrupados - Ghesa, where the main capabilities of the EcosimPro tool and the ESPSS libraries will be explained, as well as the status of the main developments that are currently ongoing in ESPSS.

The floor will be then opened to industrial and research institutions’ users providing the opportunity to present their work on the ESPSS, as well as different suggestions and questions stated by the different users and attendants, based on their experience and wishes.

The day will end with a round table where all the users can suggest extensions and improvements of the tool to address their new needs for future applications.

During the second day, two parallel training sessions will be given by Empresarios Agrupados - Ghesa: introductory (for new users) and advanced (for users with expertise in ESPSS). The contents of the advanced training are partially based on users’ requests. Hence, participants are encouraged to suggest topics for the advanced session (link available in the registration form).  

The objective of the workshop is twofold. The first is to highlight the upgrades realized both on EcosimPro Platform and the ESPSS toolkit along with new extensions. These upgrades and extensions will be presented directly by the related developers. The other goal is to reinforce the constructive feed-back on the simulation tool in which the experience of developers and users are openly discussed providing the basis for future improvements of the EcosimPro/ESPSS tool environment. Therefore, ESPSS users are encouraged to elaborate and provide specific test cases upfront for troubleshooting and support during the workshop.

Temporary licenses will be provided to the attendees for the duration of the workshop.

Registration is free of charge but is required for participation and is restricted to organisations from ESA Member States and Associate Member States.
