ESA at GLOBSEC 2026

ESA Director General Josef Aschbacher participated in the 21st edition of the GLOBSEC Forum, held from 21 to 23 May in Prague, Czechia, under the theme ‘The Global Systemic Transformation. The institutional report frames the development in practical terms and ties it to the broader mission or observing effort.

This matters because Earth science becomes stronger when local observations can be placed inside a broader physical pattern that spans time and geography. The planet operates as a coupled system in which atmospheric, oceanic, cryospheric and solid-Earth processes interact across timescales from days to millions of years. A measurement that captures one variable at one location and one moment has limited interpretive value until it is embedded in the longer series and wider spatial coverage that allow natural variability to be separated from forced change. ESA Director General Josef Aschbacher participated in the 21st edition of the GLOBSEC Forum, held from 21 to 23 May in Prague. During the Forum, ESA Director General Josef Aschbacher contributed to panel discussions and exchanges highlighting the growing importance of space as a strategic domain.

At the panel ‘ Space Frontlines: Shaping European Security’, discussions underlined how space is no longer only an enabling domain, but is increasingly becoming part of the. Strengthening resilience, accelerating delivery and ensuring interoperability across European and national systems are emerging as key priorities.

On the margins of the Forum, the Director General engaged with President Petr Pavel on the Czech Republic’s growing ambitions in space and its strong and valued contribution to. He held additional bilateral meetings with senior European and international stakeholders, including representatives from government, industry and the security and defence.

Held under the auspices of President Petr Pavel, this year’s edition placed particular emphasis on Europe’s role in a rapidly evolving global system. ESA’s participation at GLOBSEC 2026 underscored the agency’s contribution to this debate, demonstrating how space capabilities support informed decision‑making, strengthen.

The broader interest lies in linking the observation to climatic, geophysical or environmental dynamics that extend well beyond the immediate event or location. Earth science is unusual in that its most important questions operate on timescales that no single research career can observe directly, making the archival record, whether in ice, sediment, rock or satellite data, as important as any new measurement. Results that can be embedded in that record, and that either confirm or challenge the patterns it reveals, carry disproportionate scientific weight.

Because the account originates with ESA Space News, it functions best as a primary institutional report that is close to the data and operations, not as independent scientific validation. Institutional communications are produced by organizations with legitimate interests in presenting their work in a favorable light, which does not make them unreliable but does make them partial. Details that complicate the narrative, including instrument limitations, unexpected failures and results below projections, tend to be minimized relative to progress messages. Technical documentation and peer-reviewed publications, where they exist, provide the complementary layer that institutional releases cannot substitute.

The next step is to place the result inside longer time series and to compare it with independent instruments and independent sites. Earth system observations gain most of their interpretive power from network density and temporal depth, not from any single measurement however precise. Model simulations that assimilate the new data will help clarify whether the observation fits comfortably within known natural variability or represents a shift that existing models do not reproduce.
