SGAC: Canada's Space Generation is Moonbound
Developed by Canadian young professionals and students, the titular theme of the UN Space Generation Advisory Council (SGAC) “Canada’s Space Generation is Moonbound” will explore a fusion of thematic areas representative of today’s space industry and its plurality. It has been prominently developed to provide insights into the growing panoramic view of Canada’s modern space sector including its makeup – an evolving genetic identity highlighting the significance of inclusion and diversity, intermixed with diversity of ideas blending technical and non-technical domains. A major highlight is accessibility to space opportunities for the Canadian youth and international outlook for space exploration through sustainable partnerships. At its heart, the core of the session reflects on Canada's heritage in space and its future: the space generation terra firma ripe of collaborative opportunities, leveraging imagination as a pivot to exploration and innovation.

The outputs generated from the session will be consolidated into a report by SGAC. They will be redirected to key stakeholders, including the Canadian Space Agency Canada's Space Advisory Board, as well as internationally to UN Committee on the Peaceful Uses of Outer Space (UN COPUOS), among others.

Using Machine Learning to Predict Risk of Asteroid Collision
Prédire la risqué d’une collision astéroïde avec la terre est un grand défi. Plusieurs astéroïdes sont trop petits, et leur orbite trop imprécise pour être détecté de la terre. Ils peuvent seulement être observé à leur approche finale a la terre. Au 15 Avril 2018 l’Astéroïde 2018 GE3 est venu entre la terre et la lune des heures avant sa détection. Les mécanismes utilisé aujourd'hui pour la détection des astéroïdes comptent trop sur des télescopes de grand champ situé sur la terre.

On doit aller au-delà de comment on analyse et détermine le risque des collisions d’astéroïdes avec terre. Pendant que la quantité d’information venant des surveillances de ciel augmente, le numéro d’astronomes pour analyser cette information reste la même.

L’intelligence artificiel est utilisé pour chercher des motifs dans des donnés énormes. J’ai utilisé un Réseau-de-Neurones « Feed-Forward » pour créer un index répertoriant le risque de collision Astéroïde-Terre à l’aide des données du Centre pour les objets proches de la Terre (CNEOS, NASA)

La couche d’entrée de ce réseau neuronal était composée de trois paramètres: la vitesse de l’astéroïde, son diamètre et sa magnitude absolu. La couche de sortie était le risque de cet astéroïde entrer en collision avec la terre. Il compare la probabilité de l'impact potentiel détecté avec le risque moyen présenté par des objets de taille identique ou supérieure au fil des ans jusqu'à la date de l'impact potentiel.

Curieusement, aucun des astéroïdes modélisés par mon algorithme n'a généré un indice de risque positif. Cela indique que le risque de collision entre un astéroïde et la Terre est très faible mais non nul. L'indice suivait un indice de risque normalisé centré sur la distribution de -4 sur échelle logarithmique. Cela implique que le risque actuel est dix mille fois inférieur à un événement de fond aléatoire.

Data Fusion and Multivariate Analysis: A Tool for the Identification of Clay Minerals During in-situ Planetary Exploration
Clay minerals present an opportunity to satisfy NASA’s primary objective of determining whether life ever arose on Mars and are recognized as high-priority targets for future missions. Clay minerals form by chemical interactions between liquid water and rock and are thus key markers of environments that may have been warm, wet, and habitable in the past. Further, clays have a demonstrated capacity to preserve chemical and morphological fossil and have even been implicated in the abiogenesis of life on Earth.
However, the exact identification of clay minerals by conventional analytical methods is complicated and often inaccurate. Analytical issues are associated with the ultrafine grain size, the compositional variability, and the structural disorders that are common amongst clay minerals. It is therefore necessary to develop a rapid analysis technique for clay properties so that upcoming exploration rovers can be reliably guided towards high-priority clay-bearing targets.
We investigate a technique known as data fusion, in which the information collected from two spectroscopic techniques, namely, laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy (RS), will be combined into a single data-set. This methodology is founded on the basic premise that aggregating information from multiple sources offers more relevant knowledge about a sample and yields more specific, refined inferences (classifications with less error and predictions with less uncertainty) than an individual source acting alone. LIBS and RS are well-suited for this task as they provide complimentary information: LIBS records the elemental composition while RS reveals molecular structures. We hypothesize that exploiting the synergistic nature of LIBS and RLS through data fusion techniques will enable definitive mineral phase identification and produce clay mineral classification models with lower uncertainty, higher reliability, and improved interpretability because the uncertain identity of a target that arises from the molecular features may be clarified by the chemical profile, and vice versa.

New Space and the role of predictive multi-physics modelling
The continually increasing availability of computational resources has completely upended the field of aviation. These predictive tools are essential to the successful design of modern commercial aircrafts as they allow for the exploration of new design spaces, reduce reliance on experimental tests, and permit an assessment of aerodynamic performance within the preliminary design stages. This greatly reduces both time and cost for the development of new aircrafts. A similar integration of numerical predictive tools has yet to take a strong foothold in the field of rocket propulsion and aerodynamics, primarily due to the inherent complexity of the multi-physics interactions in rocket sub-systems. In many of the most prominent commercial space companies, predictive modelling tools are only used for simple design decision or for a posteriori analyses. Within the emerging paradigm of New Space—where cost reduction is driving innovation—predictive computational tools are called to take a more prominent role. The present talk will highlight some of the contributions of our research group towards modelling of complex heat transfer, acoustics, thermal protection systems, and guidance and control systems applied to rocket propulsion systems.

Simulation de l'impact sur le système squelettique trois mois dans l'ISS | Simulation of the impact on the skeletal system within three months on the ISS
Il est connu que la microgravité présente dans l’espace occasionne une perte osseuse et augmente la fragilité des os des astronautes lors du retour sur terre. Les astronautes restent en moyenne de trois à six mois à l’intérieur de la Station Spatiale International (ISS) où ils sont aussi sujets aux radiations spatiales dix fois plus importantes que celles retrouvées au sol. La conférence exposera la magnitude du potentiel effet délétère de l’interaction entre l’apesanteur et les radiations ionisantes sur le système squelettique, spécifiquement dans l’ISS. En commençant par une courte revue de littérature pour poser les bases de l’actuelle compréhension de l’impact individuel de ces facteurs sur le remodelage osseux, ainsi qu’une description des techniques utilisées au sol pour simuler l’environnement spatial (hindlimb suspension, bed rest study). Il sera ensuite question de l’étude à laquelle j’ai participé, utilisant des souris males C57BL/6 suivant un protocole de suspension des pattes arrière afin de simuler l’absence de contraintes mécaniques sur les membres inférieurs retrouvée en apesanteur, en concomitance avec une irradiation ponctuelle aux rayons-X (25mGy) représentative d’une exposition de trois mois dans l’ISS. Le but étant de déterminer si l’irradiation serait suffisante pour créer des effets délétères sur les paramètres osseux, et si ces effets sont additifs ou synergétiques. Des analyses micro-architecturales et histomorphométriques ont montré que l’épaisseur des os trabéculaires et corticales diminuait (-16.77% et -10.98%; respectivement), alors que les marqueurs cellulaires de résorptions osseuse montrent une augmentation (34.70%) par rapport au contrôle. Les résultats obtenus suggèrent que l’irradiation a un effet délétère additif sur la perte osseuse et modifie la balance entre résorption osseuse (ostéoclastes) et formation osseuse (ostéoblastes). La conclusion montrera les techniques futures (microscopie confocal et histochimie) qui permettront une analyse plus précise des composantes cellulaires (ostéoblastes, ostéoclastes, ostéocytes) agissant sur le remodelage osseux.

High-Performance Thermoplastics for Lunar Exploration

Over the last decade, advanced engineering thermoplastics (polyether ether ketones (PEEKs), polyetherimides (PEIs), etc.) have received increased attention and interest for automotive, energies, aeronautic and aerospace applications. In these domains, high-performance thermoplastics are being developed to bring lightness in combination with exceptional mechanical, thermal and chemical properties. For spatial and/or lunar environment applications, various parameters should be considered when developing material formulations, including tolerance to extreme temperature changes (- 200° C to + 100° C), resistance to abrasive and electrostatic nanoscale dust, adequate outgassing properties, and resistance to high-energy radiations.

The main objective of this work is to develop high-performance polymer blends/nanocomposites materials for the design of the next generation of lunar rovers. This work is part of a multidisciplinary project made possible by the cooperation between the Research Center for High Performance Polymer and Composite Systems (CREPEC), a FRQ-NT Strategic Cluster, and the Canadian Space Agency.
