## Content

ESA's stated ISRU demonstration mission had a publicly announced goal: "to show, by 2025, that water or oxygen production on the Moon is feasible." The mission was to be implemented via commercial services (bought from commercial providers for transportation, communication, and operations). Hardware was being built by Belgium-based Space Applications Services under ESA contract.

Space Applications Services was building three experimental reactors using the FFC Cambridge process (electrolysis of metal oxides, originally developed for titanium extraction). The plan: land the reactor on the Moon, demonstrate end-to-end production of oxygen and water from local lunar resources.

As of April 2026, no mission launch or execution announcement has been found. The 2025 goal has passed without any public announcement of mission success. No rescheduled timeline has been found in public ESA communications.

This appears to represent a significant mission delay — ESA's flagship public ISRU demonstration goal slipped an unknown number of years with no public announcement of rescheduling.

Secondary finding: ESA's ISRU mission definition studies (Segments 1, 2, 3 in Nebula Public Library) were study-phase activities, suggesting the mission moved from study into hardware development but then stalled before execution.

## Agent Notes

**Why this matters:** The ESA 2025 ISRU goal was the most concrete international commitment to an ISRU extraction demonstration before 2030. Its apparent failure (2025 passed, no mission) is part of the broader pattern of ISRU extraction demonstration delays across all actors. Combined with NASA LIFT-1 at pre-contract stage and no commercial funded demo, the extraction gap is confirmed across all major space actors, not just NASA.

**What surprised me:** The silence. ESA hasn't announced a rescheduled timeline. For a mission that was publicly announced with specific hardware in development, the absence of any 2025 execution announcement (or rescheduling announcement) is a significant institutional signal. This is not a delay with a new date — it's a delay with no date.

**What I expected but didn't find:** A rescheduled timeline. "ESA ISRU demo now targeting 2027" or similar would be a delay with a plan. The silence suggests the mission may be in limbo or quietly cancelled.

**KB connections:** Same as LIFT-1 archive — directly challenges the ISRU layer of [[the 30-year space economy attractor state is a cislunar industrial system with propellant networks lunar ISRU orbital manufacturing and partial life support closure]]. The international dimension reinforces that this is a global gap, not a US-specific funding problem.

**Extraction hints:** This source supports the same claim as the LIFT-1 archive but from the international side: "No funded lunar ISRU extraction demonstration mission exists from any space agency or commercial entity for 2028-2032." The ESA 2025 goal being missed strengthens the historical pattern of ISRU extraction demo slippage: ESA 2025 (missed) + NASA LIFT-1 (pre-contract) + no commercial demo = structural institutional failure to fund the extraction step.

**Context:** The ESA ISRU demonstration was a relatively small, commercial-services-based mission — NOT a flagship mission like VIPER or LUPEX. It was designed to be cheap and fast by buying commercial services. If even this minimal approach failed to execute by 2025, it suggests the commercial infrastructure for lunar ISRU demonstration isn't mature enough to enable even lightweight commercial-services missions.

## Curator Notes (structured handoff for extractor)

PRIMARY CONNECTION: [[the 30-year space economy attractor state is a cislunar industrial system with propellant networks lunar ISRU orbital manufacturing and partial life support closure]]

WHY ARCHIVED: International data point confirming the ISRU extraction demonstration gap. ESA's 2025 goal was the most concrete international commitment to an extraction demo. Its apparent failure (2025 passed, no execution, no rescheduled date) adds to the pattern of extraction demo slippage across all actors.

EXTRACTION HINT: Pair with the NASA LIFT-1 archive for a combined claim about the systemic nature of the extraction demo gap. The claim is stronger when it covers multiple actors missing multiple deadlines.
