In recent years, the integration of Artificial Intelligence (AI) has revolutionized the field, offering unprecedented opportunities to enhance the efficiency, autonomy and intelligence of space missions. This survey paper aims to provide a comprehensive overview of the multifaceted applications of AI in space exploration, exploring the evolution of this synergy and its impact on mission success, scientific discovery, and the future of space endeavors. Indian Space Research Organization (ISRO) has achieved great feats in the recent moon mission (Chandrayaan-3) and sun mission (Aditya L1) by using artificial intelligence to enhance moon navigation as well as help young scientists to study the Sun even before the launch by creating AI-generated image visualizations. Throughout this survey, we will review key advancements, challenges and prospects in the intersection of AI and space exploration. As humanity continues its quest to explore the cosmos, the integration of AI promises to unlock new frontiers, reshape mission architectures, and redefine our understanding of the universe. This survey aims to serve as a comprehensive resource for researchers, engineers and enthusiasts interested in the dynamic and evolving landscape of AI applications in space exploration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20exploration" title=" space exploration"> space exploration</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20missions" title=" space missions"> space missions</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a> </p> <a href="https://publications.waset.org/abstracts/188421/orbiting-intelligence-a-comprehensive-survey-of-ai-applications-and-advancements-in-space-exploration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188421.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">33</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1759</span> A Radiofrequency Based Navigation Method for Cooperative Robotic Communities in Surface Exploration Missions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francisco%20J.%20Garc%C3%ADa-de-Quir%C3%B3s">Francisco J.

For this approach to succeed, it is necessary however to deploy the required infrastructure for the robotic community to achieve efficient self-localization as well as relative positioning and communications between nodes. In this paper, an exploration mission concept in which two cooperative robotic systems co-exist is presented. This paradigm hinges on a community of reference agents that provide support in terms of communication and navigation to a second agent community tasked with exploration goals. The work focuses on the role of the agent community in charge of the overall support and, more specifically, will focus on the positioning and navigation methods implemented in RF microwave bands, which are combined with the communication services. An analysis of the different methods for range and position calculation are presented, as well as the main limiting factors for precision and resolution, such as phase and frequency noise in RF reference carriers and drift mechanisms such as thermal drift and random walk. The effects of carrier frequency instability due to phase noise are categorized in different contributing bands, and the impact of these spectrum regions are considered both in terms of the absolute position and the relative speed. A mission scenario is finally proposed, and key metrics in terms of mass and power consumption for the required payload hardware are also assessed. For this purpose, an application case involving an RF communication network in UHF Band is described, in coexistence with a communications network used for the single agents to communicate within the both the exploring agents as well as the community and with the mission support agents. The proposed approach implements a substantial improvement in planetary navigation since it provides self-localization capabilities for robotic agents characterized by very low mass, volume and power budgets, thus enabling precise navigation capabilities to agents of reduced dimensions. Furthermore, a common and shared localization radiofrequency infrastructure enables new interaction mechanisms such as spatial arrangement of agents over the area of interest for distributed sensing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cooperative%20robotics" title="cooperative robotics">cooperative robotics</a>, <a href="https://publications.waset.org/abstracts/search?q=localization" title=" localization"> localization</a>, <a href="https://publications.waset.org/abstracts/search?q=robot%20navigation" title=" robot navigation"> robot navigation</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20exploration" title=" surface exploration"> surface exploration</a> </p> <a href="https://publications.waset.org/abstracts/73661/a-radiofrequency-based-navigation-method-for-cooperative-robotic-communities-in-surface-exploration-missions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73661.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">294</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1758</span> Entry, Descent and Landing System Design and Analysis of a Small Platform in Mars Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniele%20Calvi">Daniele Calvi</a>, <a href="https://publications.waset.org/abstracts/search?q=Loris%20Franchi"> Loris Franchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabrina%20Corpino"> Sabrina Corpino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thanks to the latest Mars mission, the planetary exploration has made enormous strides over the past ten years increasing the interest of the scientific community and beyond. These missions aim to fulfill many complex operations which are of paramount importance to mission success. Among these, a special mention goes to the Entry, Descent and Landing (EDL) functions which require a dedicated system to overcome all the obstacles of these critical phases. The general objective of the system is to safely bring the spacecraft from orbital conditions to rest on the planet surface, following the designed mission profile. For this reason, this work aims to develop a simulation tool integrating the re-entry trajectory algorithm in order to support the EDL design during the preliminary phase of the mission. This tool was used on a reference unmanned mission, whose objective is finding bio-evidence and bio-hazards on Martian (sub)surface in order to support the future manned mission. Regarding the concept of operations (CONOPS) of the mission, it concerns the use of Space Penetrator Systems (SPS) that will descend on Mars surface following a ballistic fall and will penetrate the ground after the impact with the surface (around 50 and 300 cm of depth). Each SPS shall contain all the instrumentation required to sample and make the required analyses. Respecting the low-cost and low-mass requirements, as result of the tool, an Entry Descent and Impact (EDI) system based on inflatable structure has been designed. Hence, a solution could be the one chosen by Finnish Meteorological Institute in the Mars Met-Net mission, using an inflatable Thermal Protection System (TPS) called Inflatable Braking Unit (IBU) and an additional inflatable decelerator. Consequently, there are three configurations during the EDI: at altitude of 125 km the IBU is inflated at speed 5.5 km/s; at altitude of 16 km the IBU is jettisoned and an Additional Inflatable Braking Unit (AIBU) is inflated; Lastly at about 13 km, the SPS is ejected from AIBU and it impacts on the Martian surface. Since all parameters are evaluated, it is possible to confirm that the chosen EDI system and strategy verify the requirements of the mission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EDL" title="EDL">EDL</a>, <a href="https://publications.waset.org/abstracts/search?q=Mars" title=" Mars"> Mars</a>, <a href="https://publications.waset.org/abstracts/search?q=mission" title=" mission"> mission</a>, <a href="https://publications.waset.org/abstracts/search?q=SPS" title=" SPS"> SPS</a>, <a href="https://publications.waset.org/abstracts/search?q=TPS" title=" TPS"> TPS</a> </p> <a href="https://publications.waset.org/abstracts/105604/entry-descent-and-landing-system-design-and-analysis-of-a-small-platform-in-mars-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105604.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">169</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1757</span> Cognitive Performance and Physiological Stress during an Expedition in Antarctica</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9e-Anne%20Parent">Andrée-Anne Parent</a>, <a href="https://publications.waset.org/abstracts/search?q=Alain-Steve%20Comtois"> Alain-Steve Comtois</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Antarctica environment can be a great challenge for human exploration. Explorers need to be focused on the task and require the physical abilities to succeed and survive in complete autonomy in this hostile environment. The aim of this study was to observe cognitive performance and physiological stress with a biomarker (cortisol) and hand grip strength during an expedition in Antarctica. A total of 6 explorers were in complete autonomous exploration on the Forbidden Plateau in Antarctica to reach unknown summits during a 30 day period. The Stroop Test, a simple reaction time, and mood scale (PANAS) tests were performed every week during the expedition. Saliva samples were taken before sailing to Antarctica, the first day on the continent, after the mission on the continent and on the boat return trip. Furthermore, hair samples were taken before and after the expedition. The results were analyzed with SPSS using ANOVA repeated measures. The Stroop and mood scale results are presented in the following order: 1) before sailing to Antarctica, 2) the first day on the continent, 3) after the mission on the continent and 4) on the boat return trip. No significant difference was observed with the Stroop (759±166 ms, 850±114 ms, 772±179 ms and 833±105 ms, respectively) and the PANAS (39.5 ±5.7, 40.5±5, 41.8±6.9, 37.3±5.8 positive emotions, and 17.5±2.3, 18.2±5, 18.3±8.6, 15.8±5.4 negative emotions, respectively) (p>0.05). However, there appears to be an improvement at the end of the second week. Furthermore, the simple reaction time was significantly lower at the end of the second week, a moment where important decisions were taken about the mission, vs the week before (416±39 ms vs 459.8±39 ms respectively; p=0.030). Furthermore, the saliva cortisol was not significantly different (p>0.05) possibly due to important variations and seemed to reach a peak on the first day on the continent. However, the cortisol from the hair pre and post expedition increased significantly (2.4±0.5 pg/mg pre-expedition and 16.7±9.2 pg/mg post-expedition, p=0.013) showing important stress during the expedition. Moreover, no significant difference was observed on the grip strength except between after the mission on the continent and after the boat return trip (91.5±21 kg vs 85±19 kg, p=0.20). In conclusion, the cognitive performance does not seem to be affected during the expedition. Furthermore, it seems to increase for specific important events where the crew seemed to focus on the present task. The physiological stress does not seem to change significantly at specific moments, however, a global pre-post mission measure can be important and for this reason, for long-term missions, a pre-expedition baseline measure is important for crewmembers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antarctica" title="Antarctica">Antarctica</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20performance" title=" cognitive performance"> cognitive performance</a>, <a href="https://publications.waset.org/abstracts/search?q=expedition" title=" expedition"> expedition</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological%20adaptation" title=" physiological adaptation"> physiological adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=reaction%20time" title=" reaction time"> reaction time</a> </p> <a href="https://publications.waset.org/abstracts/45890/cognitive-performance-and-physiological-stress-during-an-expedition-in-antarctica" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45890.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1756</span> Development of a Web Exploration Support System Focusing on Accumulation of Search Contexts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Yamazaki">T.

Moreover, advanced exploration often conducted in intellectual activities such as surveys in research activities. This kind of exploration is conducted for a long period with trials and errors. In such a case, it is extremely important for a user to accumulate the search contexts and understand them. However, existing support systems were not effective enough since most systems could not handle the various factors involved in the exploration. This research aims to develop a novel system to support web exploration focusing on the accumulation of the search contexts. This paper mainly describes the outline of the system. An experiment using the system is also described. Finally, features of the system are discussed based on the results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=web%20exploration%20context" title="web exploration context">web exploration context</a>, <a href="https://publications.waset.org/abstracts/search?q=refinement%20of%20search%20intention" title=" refinement of search intention"> refinement of search intention</a>, <a href="https://publications.waset.org/abstracts/search?q=accumulation%20of%20context" title=" accumulation of context"> accumulation of context</a>, <a href="https://publications.waset.org/abstracts/search?q=exploration%20support" title=" exploration support"> exploration support</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20visualization" title=" information visualization"> information visualization</a> </p> <a href="https://publications.waset.org/abstracts/4213/development-of-a-web-exploration-support-system-focusing-on-accumulation-of-search-contexts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4213.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">309</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1755</span> Interstellar Mission to Wolf 359: Possibilities for the Future</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajasekar%20Anand%20Thiyagarajan">Rajasekar Anand Thiyagarajan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the driving forces of mankind is the “le r`eve d'etoiles" or the “dream of stars", which has been the dynamo of our civilization. Since the beginning of the dawn of the civilization, mankind has looked upon the heavens with wonder and he has tried to understand the meaning of those twinkling lights. As human history has progressed, the understanding of those twinkling lights has progressed, as we now know a lot of information about stars. However, the dream of stars or the dream of reaching those stars always remains within the expectations of mankind. In fact, the needs of the civilization constantly drive for better knowledge and the capability of reaching those stars is one such way that knowledge and exultation can be achieved. This paper takes a futuristic case study of an interstellar mission to Wolf 359, which is approximately 8.3 light years away from us. In terms of galactic distances, 8.3 light years is not much, but as far as present space technology capabilities are concerned, it is next to impossible for us to reach those distances. Several studies have been conducted on various missions to Alpha Centauri and other nearby stars such as Barnard's star and Wolf 359. However, taking a more distant star such as Wolf 359 will help test the mankind's drive for interstellar exploration, as exotic means of travel are needed. This paper will take a futuristic case study of the event and various possibilities of space travel will be discussed in detail. Comprehensive tables and graphs will be given, which will depict the amount of time that will pass at each mode of travel and more importantly some idea on the cost in terms of energy as well as money will be discussed within today's context. In addition, prerequisites to an interstellar mission to Wolf 359 will be given in detail as well as a sample mission which will take place to that particular destination. Even though the possibility of such a mission is probably nonexistent for the 21st century, it is essential to do these exercises so that mankind's understanding of the universe will be increased. In addition, this paper hopes to establish some general guidelines for such an interstellar mission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wolf%20359" title="wolf 359">wolf 359</a>, <a href="https://publications.waset.org/abstracts/search?q=interstellar%20mission" title=" interstellar mission"> interstellar mission</a>, <a href="https://publications.waset.org/abstracts/search?q=alpha%20centauri" title=" alpha centauri"> alpha centauri</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20diameter" title=" core diameter"> core diameter</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20length" title=" core length"> core length</a>, <a href="https://publications.waset.org/abstracts/search?q=reflector%20thickness%20enrichment" title=" reflector thickness enrichment"> reflector thickness enrichment</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20temperature" title=" gas temperature"> gas temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=reflector%20temperature" title=" reflector temperature"> reflector temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20density" title=" power density"> power density</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20of%20the%20space%20craft" title=" mass of the space craft"> mass of the space craft</a>, <a href="https://publications.waset.org/abstracts/search?q=acceleration%20of%20the%20space%20craft" title=" acceleration of the space craft"> acceleration of the space craft</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20expansion" title=" time expansion "> time expansion </a> </p> <a href="https://publications.waset.org/abstracts/33363/interstellar-mission-to-wolf-359-possibilities-for-the-future" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33363.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">428</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1754</span> Living the Religious of the Virgin Mary (RVM) Educational Mission: A Grounded Theory Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Violeta%20Juanico">Violeta Juanico</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While there was a statement made by the RVM Education Ministry Commission that its strength is its Ignacian identity, shaped by the Ignacian spirituality that permeates the school community leading to a more defined RVM school culture, there has been no empirical study made in terms of a clear and convincing conceptual framework on how the RVM Educational mission is lived in the Religious of the Virgin Mary (RVM) learning institutions to the best of author’s knowledge.

However, it is unclear what exploration and exploitation capabilities imply in improvement and development work within an operations context. So in order to better understand how to develop exploration and exploitation capabilities within operations, the main characteristics of these constructs needs to be identified and further understood. Thus, the objective of this research is to increase the understanding about exploitation and exploration characteristics, to concretize what they translates to within the context of improvement and development work in an operations unit, and to identify practical challenges. A literature review and a case study are presented. In the literature review, different interpretations of exploration and exploitation are portrayed, key characteristics have been identified, and a deepened understanding of exploration and exploitation characteristics is described. The case in the study is an operations unit, and the aim is to explore to what extent and in what ways exploration and exploitation activities are part of the improvement structures and processes. The contribution includes an identification of key characteristics of exploitation and exploration, as well as an interpretation of the constructs. Further, some practical challenges are identified. For instance, exploration activities tend to be given low priority, both in daily work as in the manufacturing strategy. Also, the overall understanding about the concepts of exploitation and exploration (or any similar aspect of dynamic improvement capabilities) is very low. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exploitation" title="exploitation">exploitation</a>, <a href="https://publications.waset.org/abstracts/search?q=exploration" title=" exploration"> exploration</a>, <a href="https://publications.waset.org/abstracts/search?q=improvement" title=" improvement"> improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20production" title=" lean production"> lean production</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing" title=" manufacturing"> manufacturing</a> </p> <a href="https://publications.waset.org/abstracts/32306/exploration-and-exploitation-within-operations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32306.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">487</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1752</span> Development of Requirements Analysis Tool for Medical Autonomy in Long-Duration Space Exploration Missions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lara%20Dutil-Fafard">Lara Dutil-Fafard</a>, <a href="https://publications.waset.org/abstracts/search?q=Caroline%20Rh%C3%A9aume"> Caroline Rhéaume</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Archambault"> Patrick Archambault</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Lafond"> Daniel Lafond</a>, <a href="https://publications.waset.org/abstracts/search?q=Neal%20W.%20Pollock"> Neal W.

The Advanced Crew Medical System - Medical Condition Requirements study, funded by the Canadian Space Agency, aimed to create knowledge content and a scenario-based query capability to support medical autonomy of astronauts. The key objective of this study was to create a prototype tool for identifying medical infrastructure requirements in terms of medical knowledge, skills and materials. A multicriteria decision-making method was used to prioritize the highest risk medical events anticipated in a long-term space mission. Starting with those medical conditions, event sequence diagrams (ESDs) were created in the form of decision trees where the entry point is the diagnosis and the end points are the predicted outcomes (full recovery, partial recovery, or death/severe incapacitation). The ESD formalism was adapted to characterize and compare possible outcomes of medical conditions as a function of available medical knowledge, skills, and supplies in a given mission scenario. An extensive literature review was performed and summarized in a medical condition database. A PostgreSQL relational database was created to allow query-based evaluation of health outcome metrics with different medical infrastructure scenarios. Critical decision points, skill and medical supply requirements, and probable health outcomes were compared across chosen scenarios. The three medical conditions with the highest risk rank were acute coronary syndrome, sepsis, and stroke. Our efforts demonstrate the utility of this approach and provide insight into the effort required to develop appropriate content for the range of medical conditions that may arise. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decision%20support%20system" title="decision support system">decision support system</a>, <a href="https://publications.waset.org/abstracts/search?q=event-sequence%20diagram" title=" event-sequence diagram"> event-sequence diagram</a>, <a href="https://publications.waset.org/abstracts/search?q=exploration%20mission" title=" exploration mission"> exploration mission</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20autonomy" title=" medical autonomy"> medical autonomy</a>, <a href="https://publications.waset.org/abstracts/search?q=scenario-based%20queries" title=" scenario-based queries"> scenario-based queries</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20medicine" title=" space medicine"> space medicine</a> </p> <a href="https://publications.waset.org/abstracts/109950/development-of-requirements-analysis-tool-for-medical-autonomy-in-long-duration-space-exploration-missions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109950.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1751</span> A Review on the Future Canadian RADARSAT Constellation Mission and Its Capabilities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Dabboor">Mohammed Dabboor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spaceborne Synthetic Aperture Radar (SAR) systems are active remote sensing systems independent of weather and sun illumination, two factors which usually inhibit the use of optical satellite imagery. A SAR system could acquire single, dual, compact or fully polarized SAR imagery. Each SAR imagery type has its advantages and disadvantages. The sensitivity of SAR images is a function of the: 1) band, polarization, and incidence angle of the transmitted electromagnetic signal, and 2) geometric and dielectric properties of the radar target. The RADARSAT-1 (launched on November 4, 1995), RADARSAT-2 ((launched on December 14, 2007) and RADARSAT Constellation Mission (to be launched in July 2018) are three past, current, and future Canadian SAR space missions. Canada is developing the RADARSAT Constellation Mission (RCM) using small satellites to further maximize the capability to carry out round-the-clock surveillance from space. The Canadian Space Agency, in collaboration with other government-of-Canada departments, is leading the design, development and operation of the RADARSAT Constellation Mission to help addressing key priorities. The purpose of our presentation is to give an overview of the future Canadian RCM SAR mission with its satellites. Also, the RCM SAR imaging modes along with the expected SAR products will be described. An emphasis will be given to the mission unique capabilities and characteristics, such as the new compact polarimetry SAR configuration. In this presentation, we will summarize the RCM advancement from previous RADARSAT satellite missions. Furthermore, the potential of the RCM mission for different Earth observation applications will be outlined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compact%20polarimetry" title="compact polarimetry">compact polarimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=RADARSAT" title=" RADARSAT"> RADARSAT</a>, <a href="https://publications.waset.org/abstracts/search?q=SAR%20mission" title=" SAR mission"> SAR mission</a>, <a href="https://publications.waset.org/abstracts/search?q=SAR%20applications" title=" SAR applications"> SAR applications</a> </p> <a href="https://publications.waset.org/abstracts/74263/a-review-on-the-future-canadian-radarsat-constellation-mission-and-its-capabilities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74263.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">185</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1750</span> Enhance Concurrent Design Approach through a Design Methodology Based on an Artificial Intelligence Framework: Guiding Group Decision Making to Balanced Preliminary Design Solution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Loris%20Franchi">Loris Franchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniele%20Calvi"> Daniele Calvi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabrina%20Corpino"> Sabrina Corpino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a design methodology in which stakeholders are assisted with the exploration of a so-called negotiation space, aiming to the maximization of both group social welfare and single stakeholder’s perceived utility. The outcome results in less design iterations needed for design convergence while obtaining a higher solution effectiveness. During the early stage of a space project, not only the knowledge about the system but also the decision outcomes often are unknown. The scenario is exacerbated by the fact that decisions taken in this stage imply delayed costs associated with them. Hence, it is necessary to have a clear definition of the problem under analysis, especially in the initial definition. This can be obtained thanks to a robust generation and exploration of design alternatives. This process must consider that design usually involves various individuals, who take decisions affecting one another. An effective coordination among these decision-makers is critical. Finding mutual agreement solution will reduce the iterations involved in the design process. To handle this scenario, the paper proposes a design methodology which, aims to speed-up the process of pushing the mission’s concept maturity level. This push up is obtained thanks to a guided negotiation space exploration, which involves autonomously exploration and optimization of trade opportunities among stakeholders via Artificial Intelligence algorithms. The negotiation space is generated via a multidisciplinary collaborative optimization method, infused by game theory and multi-attribute utility theory. In particular, game theory is able to model the negotiation process to reach the equilibria among stakeholder needs. Because of the huge dimension of the negotiation space, a collaborative optimization framework with evolutionary algorithm has been integrated in order to guide the game process to efficiently and rapidly searching for the Pareto equilibria among stakeholders. At last, the concept of utility constituted the mechanism to bridge the language barrier between experts of different backgrounds and differing needs, using the elicited and modeled needs to evaluate a multitude of alternatives. To highlight the benefits of the proposed methodology, the paper presents the design of a CubeSat mission for the observation of lunar radiation environment. The derived solution results able to balance all stakeholders needs and guaranteeing the effectiveness of the selection mission concept thanks to its robustness in valuable changeability. The benefits provided by the proposed design methodology are highlighted, and further development proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concurrent%20engineering" title="concurrent engineering">concurrent engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=negotiation%20in%20engineering%20design" title=" negotiation in engineering design"> negotiation in engineering design</a>, <a href="https://publications.waset.org/abstracts/search?q=multidisciplinary%20optimization" title=" multidisciplinary optimization"> multidisciplinary optimization</a> </p> <a href="https://publications.waset.org/abstracts/105602/enhance-concurrent-design-approach-through-a-design-methodology-based-on-an-artificial-intelligence-framework-guiding-group-decision-making-to-balanced-preliminary-design-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105602.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">136</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1749</span> Lunar Exploration based on Ground-Based Radar: Current Research Progress and Future Prospects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiangwan%20Xu">Jiangwan Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chunyu%20Ding"> Chunyu Ding</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lunar exploration is of significant importance in the development and utilization of in-situ lunar resources, water ice exploration, space and astronomical science, as well as in political and military strategy. In recent years, ground-based radar (GBR) has gained increasing attention in the field of lunar exploration due to its flexibility, low cost, and penetrating capabilities. This paper reviews the scientific research on lunar exploration using GBR, outlining the basic principles of GBR and the progress made in lunar exploration studies. It introduces the fundamental principles of lunar imaging using GBR, and systematically reviews studies on lunar surface layer detection, inversion of lunar regolith dielectric properties, and polar water ice detection using GBR. In particular, the paper summarizes the current development status of Chinese GBR and forecasts future development trends in China. This review will enhance the understanding of lunar exploration results using GBR radar, systematically demonstrate the main applications and scientific achievements of GBR in lunar exploration, and provide a reference for future GBR radar lunar exploration missions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ground-based%20radar" title="ground-based radar">ground-based radar</a>, <a href="https://publications.waset.org/abstracts/search?q=lunar%20exploration" title=" lunar exploration"> lunar exploration</a>, <a href="https://publications.waset.org/abstracts/search?q=radar%20imaging" title=" radar imaging"> radar imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=lunar%20surface%2Fsubsurface%20detection" title=" lunar surface/subsurface detection"> lunar surface/subsurface detection</a> </p> <a href="https://publications.waset.org/abstracts/190029/lunar-exploration-based-on-ground-based-radar-current-research-progress-and-future-prospects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190029.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">30</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1748</span> Mission Driven Enterprises in Ecosystems as Drivers for Sustainable System Change</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monique%20de%20Ritter">Monique de Ritter</a>, <a href="https://publications.waset.org/abstracts/search?q=Annemieke%20Roobeek"> Annemieke Roobeek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study takes a holistic multi-layered systems approach on entrepreneurship, innovation, and sustainability. Concretely we looked how mission driven entrepreneurs (level 1) employ new business models and launch innovative products and/or ideas in their enterprises, which are (level 2) operating in entrepreneurial ecosystems (level 3), and how these in turn may generate higher level sustainable change (level 4). We employed a qualitative grounded research approach in which our aim is to contribute to theory. Fourteen in-depth semi-structured interviews were conducted with mission driven entrepreneurs in the Netherlands in which their individual drives, business models, and ecosystems were discussed. Interview transcripts were systematically coded and analysed and the ecosystems were visually mapped. Most important patterns include 1) entrepreneurs have a clear sustainable mission and regard this mission as de raison d’être of their enterprise; 2) entrepreneurs employ new business models with a focus on collaboration for innovation; the business model supports or enhances the sustainable mission of the enterprise, 3) entrepreneurs collaborate in ecosystems in which a) they also regard suppliers as partners for innovation and clients as ambassadors for the sustainable mission, b) would like to improve their relationships with financial institutions as they are in the entrepreneurs’ perspective often lagging behind with their innovative ideas and models, c) they collaborate for knowledge and innovation with several parties, d) personal informal connections are very important, and e) in which the higher sustainable mission is not a point of competition but of collaboration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainability" title="sustainability">sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title=" entrepreneurship"> entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem" title=" ecosystem"> ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20models" title=" business models "> business models </a> </p> <a href="https://publications.waset.org/abstracts/27692/mission-driven-enterprises-in-ecosystems-as-drivers-for-sustainable-system-change" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27692.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">375</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1747</span> Optimal Peer-to-Peer On-Orbit Refueling Mission Planning with Complex Constraints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jing%20Yu">Jing Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongyang%20Liu"> Hongyang Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Hao"> Dong Hao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> On-Orbit Refueling is of great significance in extending space crafts' lifetime. The problem of minimum-fuel, time-fixed, Peer-to-Peer On-Orbit Refueling mission planning is addressed here with the particular aim of assigning fuel-insufficient satellites to the fuel-sufficient satellites and optimizing each rendezvous trajectory. Constraints including perturbation, communication link, sun illumination, hold points for different rendezvous phases, and sensor switching are considered. A planning model has established as well as a two-level solution method. The upper level deals with target assignment based on fuel equilibrium criterion, while the lower level solves constrained trajectory optimization using special maneuver strategies.

Building on the tradeoff argument, many authors have assumed that a company's market performance should be positively dependent on its strategic balance between exploration and exploitation over time. In this study, we apply this reasoning to the pharmaceutical industry. Using exploratory regression analysis we show that the long-term market performance of a pharmaceutical company is linked to both its ability to carry out exploratory projects and its ability to develop exploitative competencies. In particular, our findings demonstrate that, on average, the company's annual sales performance is higher the better the strategic alignment between exploration and exploitation is balanced. The contribution of our research is twofold. On the one hand, we provide empirical evidence for the initial tradeoff hypothesis and thus support the theoretical position of those who understand exploration and exploitation as strategic substitutes. On the other hand, our findings show that a balanced relationship between exploration and exploitation is also important in research-intensive industries, which naturally tend to place more emphasis on exploration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exploitation" title="exploitation">exploitation</a>, <a href="https://publications.waset.org/abstracts/search?q=exploration" title=" exploration"> exploration</a>, <a href="https://publications.waset.org/abstracts/search?q=market%20performance" title=" market performance"> market performance</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceutical%20industry" title=" pharmaceutical industry"> pharmaceutical industry</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy" title=" strategy "> strategy </a> </p> <a href="https://publications.waset.org/abstracts/128901/linking-market-performance-to-exploration-and-exploitation-in-the-pharmaceutical-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128901.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">218</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1744</span> Jesus’ Approach in Liberation of the Poor, Luke 4:18-19: Lesson for Nigerian Leaders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aboekwe">Aboekwe</a>, <a href="https://publications.waset.org/abstracts/search?q=Mary%20Emilia"> Mary Emilia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Jesus’ mission was not only a religious one but had social and political implications. From the birth to the death of Jesus, God’s message of liberation is proclaimed in and through Jesus. This work studied Jesus’ inaugural mission in Luke 4: 18 -19 in the context of Nigerian leaders. A theological interpretation was adopted and it was discovered that Luke 4: 18-19 unfolded Jesus’ mission statement. This mission statement centered in preaching the good news to the poor, the release of the captives, healing the sick, liberation to the oppressed, and favour and abundance in the land. Related to the Jewish-Roman world of Jesus and the Nigerian nation, it was discovered that most of the maladies enumerated in Jesus’ inaugural mission statement were prevalent in Nigerian society. Maladies like poverty, oppression, violence, sickness and diseases are widespread in Nigeria. Poverty affects all, irrespective of gender, religion, or ethnicity. There is insecurity everywhere. Unemployment bites harder on Nigeria’s youthful population, and they are unable to find a job at the prevailing wage rate. To this effect, therefore, this study proposes Jesus’ liberative technique as a solution to these maladies prevalent in the country. The work equally challenged the Nigerian leaders to emulate Jesus’ mission statement and take proactive measures in fighting against these social challenges resident in Nigeria today. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liberation" title="liberation">liberation</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership" title=" leadership"> leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=maladies" title=" maladies"> maladies</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty" title=" poverty"> poverty</a> </p> <a href="https://publications.waset.org/abstracts/170358/jesus-approach-in-liberation-of-the-poor-luke-418-19-lesson-for-nigerian-leaders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170358.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1743</span> Examining the Significance of Service Learning in Driving the Purpose of a Rural-Based University in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Maphosa">C.

The most effective way of achieving this goal is to be able to penetrate strategic targets. Strategic targets are generally located deep inside of the countries and are defended by modern and efficient surface to air missiles (SAM) platforms which are operated as integrated with Intelligence, Surveillance and Reconnaissance (ISR) systems. On the other hand, these high valued targets are buried deep underground and hardened with strong materials against attacks. Therefore, to penetrate these targets requires very detailed intelligence. This intelligence process should include a wide range that is from weaponry to threat assessment. Accordingly, the framework of the attack package will be determined. This mission package has to execute missions in a high threat environment. The way to minimize the risk which depends on loss of life is to use packages which are formed by UAVs. However, some limitations arising from the characteristics of UAVs restricts the performance of the mission package consisted of UAVs. So, the mission package should be formed with UAVs under the leadership of a fifth generation manned aircraft. Thus, we can minimize the limitations, easily penetrate in the deep inside of the enemy territory with minimum risk, make a decision according to ever-changing conditions and finally destroy the strategic targets. In this article, the strengthens and weakness aspects of UAVs are examined by SWOT analysis. And also, it revealed features of a mission package and presented as an example what kind of a mission package we should form in order to get marginal benefit and penetrate into strategic targets with the development of autonomous mission execution capability in the near future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UAV" title="UAV">UAV</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomy" title=" autonomy"> autonomy</a>, <a href="https://publications.waset.org/abstracts/search?q=mission%20package" title=" mission package"> mission package</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20attack" title=" strategic attack"> strategic attack</a>, <a href="https://publications.waset.org/abstracts/search?q=mission%20planning" title=" mission planning"> mission planning</a> </p> <a href="https://publications.waset.org/abstracts/10355/evaluating-the-use-of-manned-and-unmanned-aerial-vehicles-in-strategic-offensive-tasks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10355.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">550</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1741</span> The Development of a Miniaturized Raman Instrument Optimized for the Detection of Biosignatures on Europa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aria%20Vitkova">Aria Vitkova</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanna%20Sykulska-Lawrence"> Hanna Sykulska-Lawrence</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, Europa has been one of the major focus points in astrobiology due to its high potential of harbouring life in the vast ocean underneath its icy crust. However, the detection of life on Europa faces many challenges due to the harsh environmental conditions and mission constraints. Raman spectroscopy is a highly capable and versatile in-situ characterisation technique that does not require any sample preparation. It has only been used on Earth to date; however, recent advances in optical and laser technology have also allowed it to be considered for extraterrestrial exploration. So far, most efforts have been focused on the exploration of Mars, the most imminent planetary target. However, as an emerging technology with high miniaturization potential, Raman spectroscopy also represents a promising tool for the exploration of Europa. In this study, the capabilities of Raman technology in terms of life detection on Europa are explored and assessed. Spectra of biosignatures identified as high priority molecular targets for life detection on Europa were acquired at various excitation wavelengths and conditions analogous to Europa. The effects of extremely low temperatures and low concentrations in water ice were explored and evaluated in terms of the effectiveness of various configurations of Raman instruments. Based on the findings, a design of a miniaturized Raman instrument optimized for in-situ detection of life on Europa is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=astrobiology" title="astrobiology">astrobiology</a>, <a href="https://publications.waset.org/abstracts/search?q=biosignatures" title=" biosignatures"> biosignatures</a>, <a href="https://publications.waset.org/abstracts/search?q=Europa" title=" Europa"> Europa</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20detection" title=" life detection"> life detection</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman%20Spectroscopy" title=" Raman Spectroscopy"> Raman Spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/124524/the-development-of-a-miniaturized-raman-instrument-optimized-for-the-detection-of-biosignatures-on-europa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124524.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">212</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1740</span> An Analysis of Curricular and Other Curricular Activities of Ramakrishna Mission School</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shri%20Krishna%20Mishra">Shri Krishna Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Badri%20Yadav"> Badri Yadav</a> </p> <p class="card-text"><strong>Abstract:</strong></p> India is a democratic country requires creative dynamic citizen for its development.

The extent to which the demands of the astronaut occupation and exposure to spaceflight-related hazards affect the health of the astronaut population over the life course is not completely known. A better understanding of the individual, population, and mission impacts of astronaut occupational exposures is critical to providing clinical care, targeting occupational surveillance efforts, and planning for future space exploration. The ability to characterize the risk of latent health conditions is a significant component of this understanding. Provision of health screening services to active and former astronauts ensures individual, mission, and community health and safety. Currently, the NASA-Johnson Space Center (JSC) Flight Medicine Clinic (FMC) provides extensive medical monitoring to active astronauts throughout their careers. Upon retirement, astronauts may voluntarily return to the JSC FMC for an annual preventive exam. However, current retiree monitoring includes only selected screening tests, representing an opportunity for augmentation. The potential long-term health effects of spaceflight demand an expanded framework of testing for former astronauts. The need is two-fold: screening tests widely recommended for other aging populations are necessary to rule out conditions resulting from the natural aging process (e.g., colonoscopy, mammography); and expanded monitoring will increase NASA’s ability to better characterize conditions resulting from astronaut occupational exposures. To meet this need, NASA has begun an extensive exploration of the overall approach, cost, and policy implications of expanding the medical monitoring of former NASA astronauts under the Astronaut Occupational Health program. Increasing the breadth of monitoring services will ultimately enrich the existing evidence base of occupational health risks to astronauts. Such an expansion would therefore improve the understanding of the health of the astronaut population as a whole, and the ability to identify, mitigate, and manage such risks in preparation for deep space exploration missions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=astronaut" title="astronaut">astronaut</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20health" title=" long-term health"> long-term health</a>, <a href="https://publications.waset.org/abstracts/search?q=NASA" title=" NASA"> NASA</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20health" title=" occupational health"> occupational health</a>, <a href="https://publications.waset.org/abstracts/search?q=surveillance" title=" surveillance"> surveillance</a> </p> <a href="https://publications.waset.org/abstracts/58163/protecting-the-health-of-astronauts-enhancing-occupational-health-monitoring-and-surveillance-for-former-nasa-astronauts-to-understand-long-term-outcomes-of-spaceflight-related-exposures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58163.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">533</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1738</span> Study of Interplanetary Transfer Trajectories via Vicinity of Libration Points</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhe%20Xu">Zhe Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Li"> Jian Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Lvping%20Li"> Lvping Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Zezheng%20Dong"> Zezheng Dong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work is to study an optimized transfer strategy of connecting Earth and Mars via the vicinity of libration points, which have been playing an increasingly important role in trajectory designing on a deep space mission, and can be used as an effective alternative solution for Earth-Mars direct transfer mission in some unusual cases. The use of vicinity of libration points of the sun-planet body system is becoming potential gateways for future interplanetary transfer missions. By adding fuel to cargo spaceships located in spaceports, the interplanetary round-trip exploration shuttle mission of such a system facility can also be a reusable transportation system. In addition, in some cases, when the S/C cruising through invariant manifolds, it can also save a large amount of fuel. Therefore, it is necessary to make an effort on looking for efficient transfer strategies using variant manifold about libration points. It was found that Earth L1/L2 Halo/Lyapunov orbits and Mars L2/L1 Halo/Lyapunov orbits could be connected with reasonable fuel consumption and flight duration with appropriate design. In the paper, the halo hopping method and coplanar circular method are briefly introduced. The former used differential corrections to systematically generate low ΔV transfer trajectories between interplanetary manifolds, while the latter discussed escape and capture trajectories to and from Halo orbits by using impulsive maneuvers at periapsis of the manifolds about libration points. In the following, designs of transfer strategies of the two methods are shown here. A comparative performance analysis of interplanetary transfer strategies of the two methods is carried out accordingly. Comparison of strategies is based on two main criteria: the total fuel consumption required to perform the transfer and the time of flight, as mentioned above. The numeric results showed that the coplanar circular method procedure has certain advantages in cost or duration. Finally, optimized transfer strategy with engineering constraints is searched out and examined to be an effective alternative solution for a given direct transfer mission. This paper investigated main methods and gave out an optimized solution in interplanetary transfer via the vicinity of libration points. Although most of Earth-Mars mission planners prefer to build up a direct transfer strategy for the mission due to its advantage in relatively short time of flight, the strategies given in the paper could still be regard as effective alternative solutions since the advantages mentioned above and longer departure window than direct transfer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circular%20restricted%20three-body%20problem" title="circular restricted three-body problem">circular restricted three-body problem</a>, <a href="https://publications.waset.org/abstracts/search?q=halo%2FLyapunov%20orbit" title=" halo/Lyapunov orbit"> halo/Lyapunov orbit</a>, <a href="https://publications.waset.org/abstracts/search?q=invariant%20manifolds" title=" invariant manifolds"> invariant manifolds</a>, <a href="https://publications.waset.org/abstracts/search?q=libration%20points" title=" libration points"> libration points</a> </p> <a href="https://publications.waset.org/abstracts/63162/study-of-interplanetary-transfer-trajectories-via-vicinity-of-libration-points" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63162.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">244</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1737</span> Analyzing the Oil and Gas Exploration Opportunities in Poland: Five Prospective Areas Selected and Dedicated to the Tender</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krystian%20W%C3%B3jcik">Krystian Wójcik</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Wr%C3%B3blewska"> Sara Wróblewska</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcin%20%C5%81ojek"> Marcin Łojek</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Sobie%C5%84"> Katarzyna Sobień</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polish Geological Survey selected five of the most prospective areas for oil and gas exploration in Poland.

In this way, the feasibility of the lunar instrument structure is demonstrated in terms of the modal modes, stresses, and random vibration and a better understanding of the structural tests design is provided by our results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang%E2%80%99E4" title="Chang’E4">Chang’E4</a>, <a href="https://publications.waset.org/abstracts/search?q=Chinese%20national%20space%20administration" title=" Chinese national space administration"> Chinese national space administration</a>, <a href="https://publications.waset.org/abstracts/search?q=lunar%20lander%20neutron%20dosimetry" title=" lunar lander neutron dosimetry"> lunar lander neutron dosimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=nastran-patran" title=" nastran-patran"> nastran-patran</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20analysis" title=" structural analysis"> structural analysis</a> </p> <a href="https://publications.waset.org/abstracts/71329/study-case-of-spacecraft-instruments-in-structural-modelling-with-nastran-patran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71329.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">529</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1735</span> 3D High-Precision Tunnel Gravity Exploration Method for Concealed High-Density Ore-Bodies: A Case Study on the Zhaotong Maoping Carbonate-Hosted Zn-Pb-(Ag-Ge) Deposit in Northeastern Yunnan, China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Han%20Run-Sheng">Han Run-Sheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Wen-Yao"> Li Wen-Yao</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Feng"> Wang Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Fei"> Liu Fei</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiu%20Wen-Long"> Qiu Wen-Long</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Li"> Lei Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accurately positioning detection of concealed deposits or ore-bodies is one of the difficult problems in mineral exploration field. Theory calculation and exploration practices for tunnel gravity indicate that 3D high-precision Tunnel Gravity Exploration Method (TGEM) can find concealed high-density three-dimensional ore-bodies in the depth. The ore-finding breakthroughs at the depth of the Zhaotong Maoping carbonate-hosted Zn–Pb–(Ag–Ge) deposit in Northeastern Yunnan have proved that the exploration method in combination with MEAHFZ method is effective to detect concealed high-density ore-bodies. TGEM may overcome anomalous ambiguity of other geophysical methods for 3D positioning of concealed ore-bodies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20tunnel%20gravity%20exploration%20method" title="3D tunnel gravity exploration method">3D tunnel gravity exploration method</a>, <a href="https://publications.waset.org/abstracts/search?q=concealed%20high-density%20Ore-bodies" title=" concealed high-density Ore-bodies"> concealed high-density Ore-bodies</a>, <a href="https://publications.waset.org/abstracts/search?q=Zn%E2%80%93Pb%E2%80%93%28Ag%E2%80%93Ge%29%20deposit" title=" Zn–Pb–(Ag–Ge) deposit"> Zn–Pb–(Ag–Ge) deposit</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaotong%20mapping" title=" Zaotong mapping"> Zaotong mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=Northeastern%20Yunnan" title=" Northeastern Yunnan"> Northeastern Yunnan</a> </p> <a href="https://publications.waset.org/abstracts/58530/3d-high-precision-tunnel-gravity-exploration-method-for-concealed-high-density-ore-bodies-a-case-study-on-the-zhaotong-maoping-carbonate-hosted-zn-pb-ag-ge-deposit-in-northeastern-yunnan-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58530.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">326</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1734</span> Cross-Cultural Evangelism a Necessity in Contemporary Times: A Case Study of Mission of Diocese on the Niger Anglican Communion to Togo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nnatuanya%20Chinedu%20Emmanuel">Nnatuanya Chinedu Emmanuel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The focus of this research is to point out the importance of mission across nations, tribes, and languages.

New advancements in XR technologies offer expanding possibilities to advance the future of human space exploration with increased crew autonomy. This paper seeks to identify implementation gaps between existing and proposed XR space applications to inform future mission planning. A review of virtual reality, augmented reality, and mixed reality technologies implemented aboard the International Space Station revealed a total of 16 flown investigations. A secondary set of ground-tested XR human spaceflight applications were systematically retrieved from literature sources. The two sets of XR technologies, those flown and those existing in the literature were analyzed to characterize application domains and device types. Comparisons between these groups revealed untapped application areas for XR to support crew psychological health, in-flight training, and extravehicular operations on future flights. To fill these roles, integrating XR technologies with advancements in biometric sensors and machine learning tools is expected to transform crew capabilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=augmented%20reality" title="augmented reality">augmented reality</a>, <a href="https://publications.waset.org/abstracts/search?q=extended%20reality" title=" extended reality"> extended reality</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20space%20station" title=" international space station"> international space station</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20reality" title=" mixed reality"> mixed reality</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title=" virtual reality"> virtual reality</a> </p> <a href="https://publications.waset.org/abstracts/138128/analyzing-extended-reality-technologies-for-human-space-exploration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138128.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">216</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1731</span> Establishment of Precision System for Underground Facilities Based on 3D Absolute Positioning Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yonggu%20Jang">Yonggu Jang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jisong%20Ryu"> Jisong Ryu</a>, <a href="https://publications.waset.org/abstracts/search?q=Woosik%20Lee"> Woosik Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study aims to address the limitations of existing underground facility exploration equipment in terms of exploration depth range, relative depth measurement, data processing time, and human-centered ground penetrating radar image interpretation.
