Field(s) of activity for the internship

Topic of the internship: Regenerative Life Support Systems for Future Exploration Missions

Future crewed missions to Mars will require considerable amounts of water, oxygen and nutritional food and will generate significant amounts of waste, with limited or no opportunity for Earth resupply. To enable such missions, it is therefore imperative to aim for enhanced autonomy. One such solution is the use of regenerative technologies to recycle crew waste, revitalize the air and produce water and food.

For more than 30 years, ESA has been active in the field of regenerative life support systems. MELiSSA (Micro-Ecological Life Support System Alternative) is the European project of circular life support systems. Inspired by terrestrial ecosystems, it was established to gain knowledge on regenerative systems, aiming at the highest degree of autonomy and consequently at producing food, water, and oxygen from mission wastes. This is often called Functional Ecology. Based on the collaboration of a large European industrial and academic consortium, MELiSSA is a pioneering effort and has contributed significantly to our understanding of how transformation processes can be integrated into circular systems.

To reach this objective, the MELiSSA project generated the concept of a "loop", inspired from a natural ecosystem and based on five interconnected compartments (waste degrading and transformation bioreactors; 2 compartments concomitantly in charge of oxygen production, water recycling and edible microalgae / higher plant production; a compartment with crew as a food, water and air consumer and producer of metabolic waste streams). As a part of the development of the project, a MELiSSA Pilot Plant (MPP) laboratory has been set up at the Universitat Autònoma de Barcelona. The role of the MPP is to demonstrate the feasibility, reliability, and robustness of the MELiSSA loop concept and systemic approach. For cost and safety reasons, demonstration is today performed with a mock-up crew of rats but in the next development steps, the MPP ambitions to transition to a human-rated facility.

The elaboration and design of a circular system such as the MELiSSA loop requires a system engineering approach and an independent procedure to evaluate and trade-off the possible system architectures. In the frame of MELiSSA, ESA has developed the ALiSSE (Advanced Life Support System Evaluator) methodology and associated software tool, based on a set of predefined criteria: mass, energy and power, crew time, efficiency, risk for human, reliability and sustainability.

In the frame of this internship, you will contribute to the system engineering activities of the MELiSSA project by using the ALiSSE methodology and recently upgraded ALiSSE software tool for different exploration mission scenarios (e.g., Mars transit mission, evolution of the MELiSSA Pilot Plant to a human-rated facility) and different life support system architectures. The work will also assess the impact of integrating plastic waste degradation in the MELiSSA loop, including state-of-the-art of the available technologies, pathway study for synthesis of bioproducts as building blocks for space applications, evaluation of the degrees of freedom and ALiSSE trade-off and evaluation.
