The ESA Resilience from Space program emerged from a recognized need to strengthen Europe’s space-based intelligence capabilities. Space is increasingly vital for security, providing data for everything from weather monitoring to military surveillance. However, Europe’s current national satellite systems are limited, offering only 3–4 images per day, which isn’t enough for real-time situational awareness during crises. This limitation contrasts with global trends, where defense-related space spending accounts for about 50% of total space budgets, while Europe’s share is around 15%. This gap underscores the urgency for Europe to invest in advanced security solutions to maintain sovereignty and keep pace with global advancements.
The program is part of the Earth Observation Government Service, a broader initiative studied by both ESA and the European Commission. ESA Resilience from Space is the first implementation step, focusing on frequent Earth observations to provide security actors with up-to-date intelligence. The key feature is the potential for observations every half-hour, a significant improvement over existing capabilities, enabling quicker and more informed decision-making.
The proposed system is likely to involve a constellation of satellites designed for frequent revisits, drawing inspiration from the U.S. National Reconnaissance Office (NRO) system, which deployed over 200 satellites in two years for similar purposes. A satellite constellation allows continuous monitoring of critical areas, ensuring timely data for security responses. This approach requires coordination between multiple satellites to cover large areas efficiently, a strategy that could enhance Europe’s ability to monitor global events in real time.
The joint effort with the European Commission is important, with a task force examining the system’s feasibility. In January 2024, ESA awarded one-year feasibility studies to companies like OHB and Telespazio, assessing the technical and commercial viability of the satellite constellation. These studies are essential for determining how to build and operate such a system, ensuring it meets Europe’s security needs while remaining cost-effective.
As of May 2025, the program is in its early stages, with feasibility studies ongoing. ESA plans to request funding at its ministerial conference, known as CM25, scheduled for November 2025. If approved, the first phase will be coordinated with the EU’s Earth Observation Government Service. Further development and deployment could be supported by the EU’s next Multiannual Financial Framework (MFF), starting in 2028, providing a long-term funding framework for the initiative.
This timeline reflects a strategic approach, balancing immediate needs with sustainable growth. The funding request at CM25 is a key step, as it will determine whether the program can move from planning to implementation, potentially transforming Europe’s space-based security infrastructure.
Beyond enhancing security, the Resilience from Space program aligns with ESA’s focus on rapid and resilient crisis response. This includes reinforcing ground-based systems that might be compromised by natural disasters, such as earthquakes or floods, or malicious actions, like cyberattacks. By providing space-based alternatives, the program ensures Europe can maintain critical services and communications even in adverse conditions, offering a dual-purpose approach that benefits both security and disaster management.
However, this expansion into security roles has sparked some discussion, given ESA’s traditional focus on civil programs for peaceful purposes, as outlined in its founding convention from 50 years ago. While some programs, like launch vehicle development, have had security applications, the Resilience from Space program marks a more explicit move into defense-related activities. This shift is seen as necessary to address modern security challenges, but it also highlights the evolving role of space agencies in balancing civil and security objectives.
The program responds to member states’ requests for security-focused initiatives, reflecting Europe’s need to catch up in the global defense space race. The disparity in spending—50% globally versus 15% in Europe—underscores the strategic importance of this program. By investing in space-based intelligence, Europe aims to enhance its sovereignty and resilience, ensuring it can monitor and respond to threats effectively. This aligns with broader efforts to strengthen Europe’s position in the global space economy, where security and defense are increasingly intertwined with commercial and scientific activities.
