MELISSA: Overview of the Project and Perspectives
Bibliographic record
Abstract
<div class="htmlview paragraph">The MELISSA (Micro-Ecological Life Support Alternative) project was initiated in 1989. The recycling system is conceived as a micro-organisms and higher plants based ecosystem. As a matter of fact, it is intended as a tool to gain understanding of closed life support, as well as the development of the technology for a future life support system for long term manned space missions, e.g. a lunar base or a mission to Mars.</div> <div class="htmlview paragraph">The collaboration was established through a Memorandum of Understanding and is managed by ESA. It involves several independent organisations: University of Ghent, EPAS, SCK, VITO (B), University of Clermont Ferrand, SHERPA (F), University “Autonoma” of Barcelona (E), University of Guelph (CND). It is co-funded by ESA, the MELISSA partners, the Belgian (DWTC), the Spanish (CIRIT and CICYT) and Canadian (CRESTech, CSA) authorities. The driving element of MELISSA is the production of food water and oxygen from organic waste (inedible biomass, CO2, faeces, urea). Based on the principle of an “aquatic” ecosystem, MELISSA process comprises 5 compartments from the anoxygenic fermenter up to the photosynthetic one (algae and higher plants). The choice of this compartmentalised structure is required by the very high level of safety requirements and justified by the need of an engineering approach and to build deterministic control strategy.</div> <div class="htmlview paragraph">During the past 15 years of research and development, a very progressive approach has been developed to understand and control the MELISSA loop. This approach starts from the selection of the microbial strains and higher plant crops, their characterisation and mathematical modelling, the validation of the control strategy, up to the demonstration on Earth, at pilot scale.</div> <div class="htmlview paragraph">The project is organised in 5 phases: Basic R&amp;D, Preliminary flight experiment, Ground &amp; space demonstration, Terrestrial transfer, Education &amp; communication.</div>

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
