Fire Delays Installation of DLR’s Lunar Greenhouse Project

A fire at an external contractor’s facility has forced the German Aerospace Center (DLR) to postpone the installation of its containerised greenhouse designed to simulate growing crops on the Moon, shifting the project timeline into the second quarter of 2027.

The fire was disclosed in a response to a parliamentary inquiry published by the German Bundestag on October 20, and the delay pushes the deployment of the EDEN-LUNA container beyond its original 2026 installation target.

The Tech TL;DR:

• A fire during the refurbishment of the EDEN-LUNA greenhouse container at an external contractor’s site has delayed the installation.
• The greenhouse is a key component for testing robotic plant maintenance and nutrient recovery systems in simulated lunar environments.
• Installation at the LUNA facility in Cologne is now scheduled for Q2 2027, following a DLR acknowledgment of the delay on September 4.

The EDEN-LUNA project builds on the agency’s previous EDEN ISS campaign, which operated near Germany’s Neumayer III research station in Antarctica between 2018 and 2022. Following the dismantling and return of that hardware to Germany in April 2023, the DLR began refurbishing and upgrading the container at its Institute of Space Systems in Bremen. The upgraded facility aims to integrate robotic assistance, automated plant monitoring, and systems designed to recover nutrients from waste products, to study potential technologies for growing fresh food during extended missions to the Moon and Mars.

The LUNA facility itself, inaugurated in September 2024, is jointly operated by DLR and the European Space Agency and is used to test technologies and train astronauts for future missions to the Moon, offering roughly 700 square meters of simulated lunar terrain. According to documentation from the parliamentary inquiry published by the German Bundestag, the fire occurred during the refurbishment phase at the contractor’s site.

While the report confirmed the incident, it provided no specifics regarding the extent of the damage or what had been damaged.

This greenhouse initiative is part of a broader international effort to solve the logistical bottleneck of human survival in extraterrestrial environments. Alongside NASA and the Canadian Space Agency (CSA), the DLR is developing the Lunar Agriculture Module – Ground Test Demonstrator (LAM-GTD). The project aims to address extreme temperature fluctuations, lack of fertile soil, scarce water, and the high radiation levels inherent to the lunar surface.

The collaboration between the DLR, NASA, and the CSA is set to decide by 2032 at the latest whether and how the demonstrator will actually be constructed; the planned demonstrator will first be built entirely on Earth. For now, the focus remains on the Earth-based LUNA facility in Cologne. The specific impact of the fire on the greenhouse remains unclear, as the parliamentary response did not specify what had been damaged.

How will the fire impact the planned 2027 deployment?
The incident has delayed the installation of the EDEN-LUNA greenhouse to the second quarter of 2027, according to the German Bundestag inquiry, following the fire that occurred while the container was being refurbished at the contractor’s facility.

What technologies are being tested in the EDEN-LUNA greenhouse?
The facility is designed to test robotic assistance, automated plant monitoring, and nutrient recovery systems from waste products, building on the previous EDEN ISS campaign in Antarctica.
