| Summary: | The 44th International Conference on Environmental Systems was held in Tuscon, Arizona, USA on 13 July 2014 through 17 July 2014. Matthew T. Bamsey, German Aerospace Center (DLR), Germany Paul Zabel, German Aerospace Center (DLR), Germany Conrad Zeidler, German Aerospace Center (DLR), Germany Lucie Poulet, German Aerospace Center (DLR), Germany Daniel Schubert, German Aerospace Center (DLR), Germany Eberhard Kohlberg, Alfred Wegener Institute for Polar and Marine Research, Germany Designs for an Antarctic plant production system to be deployed at Germany’s Neumayer Station III are presented. Characterization and testing of several key controlled environment agriculture technologies are ongoing at the German Aerospace Center’s Institute of Space Systems. Subsystems under development at the Evolution and Design of Environmentally-Closed Nutrition-Sources (EDEN) laboratory include, tuned LED lighting, aeroponic nutrient delivery, ion-selective sensors and modular growth pallets. The Antarctic greenhouse module baseline form factor is a standard sea shipping container, which allows for use of nominal Antarctic logistics networks. The facility will be fixed onto a specially constructed platform and co-located near the Alfred Wegner Institute’s Neumayer Station III. The plant production facility will be operated year-round with maximum production per unit volume achieved through the deployment of modular grow units in a stackable rack architecture. In such a configuration the greenhouse module system can provide several kilograms of fresh edible biomass per day. Forty foot and 20 ft container configurations are described as well as the general design requirements, including specifics relevant to operations at Neumayer III. Successful deployment of such a facility will further the technology readiness and operational experience of space-based bioregenerative life support systems. Finally, the general design is presented in the context of an historical review of past Antarctic plant production facilities. ...
