D2.5 Design Report

This document provides a summary of the results of the two week EDEN ISS concurrent engineering design study conducted from Sep 7-18, 2015. The primary goal of the study was to produce a preliminary design of the EDEN ISS Mobile Test Facility. This preliminary design includes details from all Mobile Test Facility subsystems as well as initial details on a number of scientific and operational themes relevant to the EDEN ISS project. It is important to note, that the design of the Mobile Test Facility will continue to evolve, especially at the subsystem level, but that this document represents a snapshot of the design at the system level, and its status at the completion of the concurrent engineering design study in conjunction with its associated period of post-processing. The design study also generated a number of important supplementary reference documents including subsystem block diagrams and detailed ‘subsystem calculators’ which detail all subsystem components, quantities, estimated mass, volume and power in addition to a first detailed estimate of project spares and consumables. Although extracts of this information are included directly in the report, the current drafts of these documents should be referenced as separate files. The EDEN ISS concurrent engineering design study has matured the design of the Mobile Test Facility and its Future Exploration Greenhouse, Service Section (including the ISPR full rack plant growth system demonstrator) and cold porch. The study has proven the feasibility of the EDEN ISS project and demonstrated that the facility will serve as a valuable resource to the Neumayer III Antarctic Station and as a test-bed for testing plant growth technologies and operational techniques for use within future space-based missions. &nbsp
