EDEN ISS is a project focused on the ‘Ground Demonstration of Plant Cultivation Technologies and ¬Operation in Space’ and the enhancement of those technologies, ‘For Safe Food Production on-board the International Space Station (ISS) and Future Human Space Exploration Vehicles and Planetary Outposts.’

The overall goal of the EDEN ISS project is to further advance key controlled environment agriculture technologies beyond the state-of-the-art, including; an advanced nutrient delivery system, a high performance LED lighting system, a bio-detection and decontamination system and food quality and safety procedures and technologies.



A mobile container-sized greenhouse test facility will be built to demonstrate and validate different key technologies and procedures necessary for safe food production within a (semi-) closed system.

The test facility will be designed to fit into standardized shipping containers and will consist of three essential ‘parts.’

The service section will house the main support subsystems, including; thermal, power, air ventilation and nutrient/water subsystems and will provide working space for pre- ¬and harvest procedures. The International Standard Payload Rack (ISPR) section will contain two rack systems for plant production (similar to the rack-type used on the ISS) and the Future Exploration Greenhouse (FEG) will consist of a highly adaptable multi-shelf growth system, capable of maintaining a number of different environmental settings.

The plant cultivation technologies will first be tested in a laboratory setting at the sites of the consortium partners. All systems will be integrated at DLR in Bremen, followed by an extensive test period. In October 2017, the complete facility will be shipped to the German Neumayer III station in Antarctica. The station is operated by the Alfred-Wegener-Institute and has unique capabilities and infrastructure for testing plant cultivation under extreme environmental and logistical conditions. It is foreseen that the container-sized greenhouse of the EDEN ISS project will provide year-round fresh food supplementation for the Neumayer Station III crew.
