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.’

A sustained human presence in space requires the development of new technologies to maintain environmental control, manage waste, to provide water, oxygen and food, and to keep astronauts healthy and psychologically fit. Innovative food cultivation technologies in closed-loop life support systems must be developed as an integral part of future space systems. The goal of the EDEN ISS project is to advance controlled environment agriculture technologies beyond the state-of-the-art. It focuses on ground demonstration of plant cultivation technologies and their application in space.

EDEN ISS develops an advanced nutrient delivery system, a high-performance LED lighting system, a bio-detection and decontamination system, imaging systems for monitoring plant health, and technologies for ensuring food quality and safety for integration within a Mobile Test Facility.

During the EDEN ISS Analogue Mission Antarctica (conducted since February 2018), the Mobile Test Facility provides fresh produce for the crew at the Neumayer III Antarctic station, operated by the Alfred-Wegener-Institute, and serves as an analogue environment for testing plant cultivation under extreme environmental and logistical conditions.

EDEN ISS Mobile Test Facility consists of two shipping containers that are subdivided into three distinct sections. The facility is operated by a crew member, with an emphasis on remote monitoring and operations.

The cold porch/airlock is a small buffer room to limit the entry of cold air into the Future Exploration Greenhouse when the main access door of the facility is in use. This section is also used for storage purposes.

The service section houses the main support subsystems, including; thermal, power, air management and nutrient/water subsystems and provides working space for pre- and post-harvest procedures. The plant cultivation system uses a space light-ready International Standard Payload Rack (ISPR) and is integrated within the service section.

The Future Exploration Greenhouse (FEG) is the main plant growth area of the Mobile Test Facility and consists of a highly adaptable multi-shelf growth system. It is capable of maintaining a number of different environmental settings.
