ESA Nears Finalization of $25.6 Billion Space Program Package Amid Budget Uncertainties

ESA’s Major Funding Package Nears Completion

The European Space Agency is putting the final touches on a comprehensive 22-billion-euro ($25.6 billion) program package for presentation at next month’s ministerial conference, according to agency leadership. Despite facing significant budget uncertainties from international partners and internal funding challenges, sources indicate the overall package size has remained largely unchanged during preparation.

Ministerial Conference Preparations

During an October 23 briefing following an ESA Council meeting, agency officials revealed they had nearly completed the three-year program package scheduled for presentation to member states at the November 26-27 ministerial conference in Bremen, Germany. Josef Aschbacher, ESA’s director general, described the council discussions as “extremely constructive and positive” while acknowledging that significant work remains before the final proposal is ready., according to recent developments

“We still have a lot of work to do. This is normal in the final stretch of preparing the ministerial package,” Aschbacher stated, noting that another council meeting is planned for November 7 to resolve remaining issues. The report states that not all program details have been finalized, but the overall financial scope has stayed consistent throughout the planning process.

Mission Adjustments and Budget Challenges

One significant change to the proposed package involves the removal of the TRUTHS Earth science mission, which was designed to calibrate climate models through precise measurement of solar radiation. According to agency statements, the mission was dropped for “affordability reasons” after the United Kingdom, its primary supporter, reportedly withdrew funding following a recent spending review.

The agency also faces external budget uncertainties, particularly regarding NASA’s participation in joint science and exploration projects. Analysis suggests that NASA’s proposed fiscal 2026 budget, which includes potential cancellations of lunar Gateway and Orion programs beyond Artemis 3, creates complications for ESA’s planning. Although congressional spending bills would override many proposed cuts, a final U.S. budget resolution is not expected before ESA’s ministerial conference.

“We all know very well that budget decisions have yet to be made in the United States. We are eagerly awaiting those,” Aschbacher commented. “It’s difficult to speculate what those decisions will be.”, according to industry reports

Program Adaptations and Backup Plans

ESA is proceeding with development of components for Gateway and the Orion service module despite U.S. budget uncertainties. However, agency leadership considers it unlikely that NASA will continue the Mars Sample Return mission, for which ESA is developing the Earth Return Orbiter. According to reports, ESA is preparing “backup solutions” that could convert the orbiter into a standalone Mars mission if necessary.

Regarding the ExoMars Rosalind Franklin rover, analysts suggest ESA expects continued NASA support despite budget uncertainties. The Senate’s appropriations bill includes funding for NASA’s contributions to the rover, though the House version does not explicitly mention them.

Internal Funding and Review Processes

Internal funding challenges also complicate the ministerial package. France, one of ESA’s largest contributors, has not finalized its budget amid government upheaval. Agency leadership indicated that French officials are “making every effort to find funding” with five weeks remaining before the conference.

ESA subjected all proposed projects to independent reviews by the agency’s inspector general, resulting in approximately 400 recommendations that have all been implemented ahead of the ministerial. Historical data from past conferences suggests that typically 93% to 95% of proposed packages receive funding, with Aschbacher noting that “it is normal that never 100% of a proposal of a director general is subscribed.”

Industry Consolidation and Competitive Landscape

The briefing occurred hours after major European aerospace companies Airbus, Leonardo, and Thales announced an agreement to combine their space businesses into a joint venture codenamed Project Bromo. The new entity would employ approximately 25,000 people and generate 6.5 billion euros in annual revenue, pending regulatory approval expected to take up to two years.

This consolidation has significant implications for ESA, as much of Airbus Defence and Space and Thales Alenia Space—two of ESA’s largest contractors—would be combined in the joint venture. When asked about the potential reduction in competition for future procurements, Aschbacher acknowledged that “this will have an impact” but expressed confidence in ESA’s ability to adapt.

“ESA has, over 50 years, always been adapting to changes in the ecosystem,” he stated. “We will make sure that our European industry at large—big, small and medium-sized companies—will succeed, and we will take measures to help them succeed.” The agency plans to conduct a detailed assessment of the joint venture’s implications after the ministerial conference.

Despite the multiple challenges, agency leadership remains optimistic about Europe’s space future. “Am I worried? No, I’m not worried,” Aschbacher concluded. “I think it’s very good news. It’s interesting news. We see new challenges coming, and we will tackle them head-on and make sure that Europe becomes even stronger than before.”
