At EPSC 2024 held in Berlin, Germany, the idea was born to bring the German Planetary Sciences community together in a new Society, to make activities in the field of planetary research more visible within Germany and beyond, to promote scientific exchange, and to strengthen cooperation between researchers, institutions and companies. In May 2025 in Münster, the German Society for Planetary Research (Deutsche Gesellschaft für Planeten­forschung, DGP, https://www.planet-dgp.de/) was then founded.

The society was introduced at an international level at EPSC-DPS 2025 in Helsinki, Finland, at a splinter meeting with about 60 participants. Since the new DGP Society and the EuroPlanet Germany Hub share many common goals, the German community (i.e. either German-speaking or working in a German institution) decided at the EPSC-DPS splinter meeting to join forces under the main umbrella of the new society.

The early-career community within Germany also created their independent subnetwork with the DGP, and following the EPEC name convention, are called "DGPEC". They organize early-career activities at the annual meetings of the DGP and at EPSC, as well as virtual get-togethers throughout the year, and present individual early-career members and their current research projects to the community as part of the monthly DGP newsletter.

The First Annual Meeting of the DGP & Europlanet Germany Hub was organized this year in March 16-18 at Freie Universität Berlin and attracted more than 200 participants and 131 scientific abstracts.

Here we will present the current status of setting up the society and links to EuroPlanet, as well as current and planned community activities.

For the last 12 years, the Swiss planetary science community has come together to form the NCCR PlanetS – a national collaboration of 4 universities all working on the topic, and representing over 80 Millions euros of funding from the universities and the Swiss National Science Foundation. In those twelve years, I’ve had many roles within this network – scientist, communication and outreach specialist, and report coordinator, giving me a great overview of the effort to grow a community together.

As the NCCR PlanetS is coming to an end, and as the community is coming together to create the Swiss Institute for Planetary Sciences (SIPS), it is the ideal time to reflect on the community building measures we implemented in the scientific and communication domains and assess their efficiency. I will also discuss what I would do differently if we would start again, or what additional initiatives I would implement nowadays to foster the genuine sense of belonging for its members.

Europlanet is a distributed research infrastructure and membership organisation that supports the planetary science and exploration communities. It offers a suite of services, developed and optimised over 20 years, including research visits to facilities and field sites, access to telescopes, mentoring and professional development programmes, bursaries, prizes, and small-scale funding schemes. Its annual meeting, the Europlanet Science Congress (EPSC), is currently the largest international meeting on planetary science, attracting over 1200 participants each year that include researchers, industry representatives, policy-makers, amateur astronomers, outreach providers and teachers. Membership of Europlanet includes individuals and organisations spread over five continents, and from a cross-cutting range of scientific disciplines, languages and cultures.

Since its foundation in 2005, Europlanet has received 28 million Euros in funding through a series of grants from the European Commission (EC). However, the EC funding landscape has been changing in recent years, and the Europlanet 2024 Research Infrastructure (RI) project that ran from 2020-2024 was one of the last opportunities to secure RI funds for a specific topic, such as planetary science. Europlanet started sustainability planning in 2013, initially with the establishment of a consortium of institutions linked by a Memorandum of Understanding (MoU), followed by the inauguration of a society of individual members in 2018.

In February 2023, Europlanet established a non-profit Association International Sans But Lucratif (AISBL) based in Brussels, Belgium, to provide it with an independent legal structure. In December 2024, a new category of organisational membership was added. Europlanet now operates as a fully self-sustaining organisation funded through revenue from EPSC and members’ subscriptions. Core activities are run through a paid Executive Office, with most community programmes implemented by voluntary committees and working groups, including the Europlanet Early Careers (EPEC) Network, Regional Hubs, Diversity Committee, Outreach Working Group and the bodies responsible for the organisation of EPSC (the Executive Committee, Local Organising Committee, Virtual Organising Committee, and Scientific Organising Committee, as well as the session conveners).

To date, organisational membership has been driven largely by institutions wishing to include facilities in the Europlanet distributed Research and Technology Infrastructure (RTI). The number and diversity of RTI facilities offered by Europlanet’s member organisations continues to grow rapidly, and the current collection covers a wide range of experimental set-ups and disciplines. Europlanet’s flagship Transnational Access (TA) programme is designed to allow researchers from anywhere in the world, and at all career stages, to access the RTI facilities to carry out short research projects, and to foster international collaborations. The programme supports the travel and local accommodation costs of the participating researchers, as well as providing a contribution to the operating costs of the facilities. The first TA call in 2026 included 25 facilities hosted by ten organisations, with a second call with additional facilities anticipated to open in September 2026. The TA programme builds on the very successful practices initiated through EC-funding; however, Europlanet is now working towards a broader role of connecting users from both the industrial and academic sectors with planetary-relevant RTI facilities through additional programmes (e.g., commercial access, negotiated rates, or voucher systems).

With minimal centralised resources, supporting a global and highly distributed network of planetary scientists and institutions can be a challenge. In practice, this means that Europlanet must be able to deploy a proactive and collaborative community that is primed and willing to share information and resources, which in turn needs to be underpinned by the efficient and coordinated flow of information and feedback. Over several years, Europlanet has developed a comprehensive communications, dissemination and training programme that supplements standard tools and platforms (website, newsletters, webinars, social media, Discord community, etc) with more community-focused initiatives, such as the interactive online Teams Days (to better cross-network the various committees and working groups), Facility Days (to bring together facility operators, users and suppliers), and the Planetary Geological Mapping Winter School (to support and grow the international planetary mapping community).

The rapid organisational changes over recent years have required some fundamental shifts in mindset and strategy with respect to how Europlanet is presented to the community. This includes the consolidation of branding and the development of industry-focused descriptions of services. The ongoing evaluation of Europlanet activities across a range of impact areas (scientific, technological, training & education, social & societal, and economic) has helped provide a robust framework for defining and prioritising which activities should be supported with the more constrained funds available beyond the EC grants.

In this talk, we will present an overview of how we have gone about developing and implementing a sustainable programme to consolidate and build Europlanet’s community and distributed infrastructure. We will discuss the main challenges and lessons learned in transitioning to a non-profit business model that can operate independently of grants, as well as future opportunities with EC-funding for collaborations and access programmes across the Physical Sciences and Engineering domain.

The Europlanet Early Career network (EPEC) was established as a platform to give early career researchers and professionals – including bachelors, masters, and doctoral students, in addition to any individual who completed their last degree up to 7 years prior – access to a community with activities and events catered to their needs. What began as an idea during EPSC 2014 in Lisbon, with short courses focused on early careers, formally took shape as EPEC under Europlanet in 2018. Over the years, EPEC has established itself as an integral part of the Europlanet community and the wider planetary science and astronomy landscape in Europe and beyond.

Over the last decade, EPEC has created various events and activities spanning the whole year such as EPEC Annual Week, inspiring stories of the month, EPEC@EPSC, podcasts, and more. The EPEC Annual Week has consistently attracted around 30-50 early career individuals over the years, whilst EPEC@EPSC experiences participation from around 80 early careers across its activities. Beyond the numbers, these events and activities have led to long-lasting connections - friendships, professional opportunities (e.g. internships), PhD opportunities, collaborations through conversations, and social interactions. For many who have volunteered and organised within EPEC, it has also been a space to develop skills that go beyond science – event management, public engagement, science communication, networking, and leadership.

With this work, we bring together years of experience to showcase the impact of EPEC on the early career community, shared both by organisers and participants. As EPEC enters its second decade, we hope this reflection serves not only as a celebration of what has been built and what we have learned over the years, but as an invitation for the community to carry it forward.

Every modern scientist faces the challenge of building a community to promote their project and turn it into a reality. But how do we move from a fragmented group of individuals to a proactive, recognizable, and collaborative network? In this presentation, I will share candid lessons from two long-term case studies from my career: the birth and growth of EUROPLANET, and the transatlantic build-up of the Jupiter exploration community.

Case Study 1: EUROPLANET – From National Silos to a European Identity

Working on the Cassini-Huygens mission in the 2000s, a small group of European scientists made a frustrating discovery: Europe had a large, talented planetary science community, but it was insufficiently visible. We worked in national silos (French, German, Italian, UK, etc.), competing quietly rather than collaborating openly. With encouragement from ESA, we decided to target the EU Framework Programme—not with a pure science proposal, but with a network proposal. The goal was community-building itself. One of the key difficulties was to get acquainted with the funding schemes and selection procedures of the Framework Programme, and to understand how to do lobbying towards  the Commission. We won in 2004. EUROPLANET was born in 2005, on the year of the landing of Huygens on Titan, and has been growing continuously over two decades.

What worked?

• Lobbying & Stakeholders: We identified key players outside science—EU officers and ESA management. They became our community’s sponsors, giving us legitimacy.
• Building Identity: We created a strong brand (name, logo, motto) deliberately. "EUROPLANET" signaled "European, not national." This gave a fragmented group a single, recognizable face at conferences and in media.
• The Catalyst Effect: Winning the first EU grant encouraged people to collaborate. That mandatory collaboration built trust that outlasted the funding.

What didn't work? Assuming that shared scientific interest alone would unite us. Of course it helped – we had a common language and shared interest. But we needed a political and financial framework on top of it.

Case Study 2: The Jupiter Exploration Community – Transatlantic Synchronization

Simultaneously, in the wake of the successful Cassini-Huygens transatlantic collaboration experience, interest in Jupiter (and Europa) grew on both sides of the Atlantic: as Jupiter and its fascinating Galilean moons appeared as the next logical step after Saturn and Titan. But Europe and the US were working independently—risking duplication or, worse, no mission at all. Using the nascent EUROPLANET network and personal contacts at NASA, we deliberately built a transatlantic community of scientists, engineers, and agency representatives before any mission was selected. Even Japan and Russia joined at the time, in what was named the EJSM-Laplace collaborative study.

What worked?

• Diversity & Inter-cultural Tensions: European and US funding cycles, meeting cultures, and decision-making styles differ dramatically. We succeeded by acknowledging these tensions openly—alternating meeting locations, co-authoring white papers, and explicitly discussing cultural differences rather than pretending they didn't exist.
• Exchange Tools (pre-social media): Before modern platforms, discipline mattered more than tool. Regular telecons, shared document repositories, and dedicated email lists created a rhythm of communication.
• Involving the Public: The Jupiter community early-on engaged amateur astronomers for observing campaigns (e.g., impacts on Jupiter). This turned citizen science into a community-building tool that produced publishable data and public visibility.

What didn't work? Waiting for agencies to solve the coordination problem. They were busy. We had to build the community first—then the agencies followed. In the end, while the two agencies developed their two missions independently, JUICE and Europa Clipper will execute together a cosmic ballet around Jupiter in the 2030’s!

Key Takeaways for Any Scientist

From these two experiences, I learned that community-building is not a "soft skill." It is a strategic activity requiring the same planning, risk-taking, and persistence as a space mission. Keys to success include (but are not limited to):

• Agency endorsement (ESA/NASA) is a powerful catalyst. Use it to bring skeptical scientists to the table.
• A strong brand (logo, motto, name) is not superficial. It creates mental shortcuts for a fragmented community to self-identify.
• Build the community before the project. For Jupiter, the community existed before the mission was approved—which made the mission inevitable.
• Explicitly manage cross-cultural tensions. Do not ignore them. Name them. Structure your meetings to address them.
• Citizen science is a low-stakes, high-reward entry point for public engagement that also strengthens internal community bonds.

Building  a community around a project remains “learning by doing” experience: everyone who believes in a beautiful and strong project should go that path. But the greatest lesson I learnt from these two experiences is this: beyond the success of the project itself, it is being part of the community that carries it out that is the most valuable and rewarding experience, for us humans.

The JUpiter ICy Moons Explorer (JUICE), ESA’s first large-class Cosmic Vision mission, was launched on 14 April 2023 and is en route to Jupiter, where it will arrive in July 2031. Over four years, the mission will explore the Jupiter system, performing Jupiter observations, flybys of the Galilean icy moons and an orbital phase around Ganymede. JUICE will investigate the icy moons’ potential habitability, focusing on their subsurface liquid oceans, and will study Jupiter as an archetype of giant planet systems. It will also address magnetospheric interactions, tidal evolution, and additional targets such as Io, minor inner moons and rings and irregular moons.

Such a large and inspiring planetary mission attracts a lot of attention in the scientific community, the general public, media and various stakeholders. It is therefore important to communicate about the mission progresses and deliver data and results to these different communities in the most appropriate ways, depending on the phase of the mission (study, development, launch campaign, cruise, science phase, post-operation and legacy).

This presentation will cover the project’s communication strategy and will highlight some concrete engagement activities. Examples to bring the general public along include the drawing contest for the Ariane 5 fairing, the launch campaign and its outreach components, activities surrounding the gravity-assist flybys, general image releases including the observation campaign of the interstellar object 3I/ATLAS or data sonification efforts.

Engaging the rest of the science community is also a big part of our communication effort. This includes, for example, regular Europlanet webinars and open calls for scientific participation. We will also explore collaborations with amateur astronomers’ networks in ground-based observations of Jupiter and stellar occultations of its moons (e.g. Kallichore), and look ahead to the rich scientific opportunities of the nominal mission phase.

The presentation will actively seek feedback from the Europlanet community on how to increase the mission’s accessibility to the public and strengthen scientific engagement for those already involved and potential newcomers.
