We will be joined remotely by Lucie Poulet of CNES (Centre National d'Études Spatiales) who will be discussing the European Space Agency's MELiSSA project, a closed loop ecosystem under development at the University of Barcelona, Spain.

MELIiSSA (Micro-Ecological Life Support System Alternative) has been conceived as a micro-organisms and higher plants based ecosystem intended as a tool to gain understanding of the behaviour of artificial ecosystems, and for the development of the technology for a future regenerative life support system for long term manned space missions, e.g. a lunar base or a mission to Mars.

• Consider what closed-loop truly means?
• What does the human body require? What is the input/output diagram and how is that manifest physically? Where is the location of the input and output?
• What does the habitat itself require? What is the input/output diagram and how is that manifest physically? Where is the location of the input and output and how do these networks relate to eachother?
• What can be truly "self-sustainable" and what requires input and output from sources beyond the system itself?
• How are the spaces of your architecture influenced, or not, by these resource needs?
