Blocher, Andrew Gene. "Alternative Mission Concepts for the Exploration of Outer Planets Using Small Satellite Swarms." DigitalCommons@CalPoly, 2017. https://digitalcommons.calpoly.edu/theses/1820.
Full textAbstract:
Interplanetary space exploration has thus far consisted of single, expensive spacecraft missions. Mission costs are particularly high on missions to the outer planets and while invaluable, finite budgets limit our ability to perform extensive and frequent investigations of the planets. Planetary systems such as Jupiter and Saturn provide extremely complex exploration environments with numerous targets of interest. Exploring these targets in addition to the main planet requires multiple fly-bys and long mission timelines. In LEO, CubeSats have changed the exploration paradigm, offering a fast and low cost alternative to traditional space vehicles. This new mission development philosophy has the potential to significantly change the economics of interplanetary exploration and a number of missions are being developed to utilize CubeSat class spacecraft beyond earth orbit (e.g., NEAScout, Lunar Ice Cube, Marco and BioSentinel). This paper takes the CubeSat philosophical approach one step further by investigating the potential for small satellite swarms to provide extensive studies of the Saturn system. To do this, an architecture was developed to best replicate the Cassini Primary Mission science objectives using swarms of CubeSats. Cassini was chosen because of its complexity and it defines a well-understood baseline to compare against. The paper outlines the overall mission architecture developed and provides a feasible initial design for the spacecraft in the architecture. The number of swarms needed, number of CubeSats per swarm, size of the CubeSats, overall science output and estimated mission cost are all presented. Additional science objectives beyond Cassini's capabilities are also proposed. Significant scientific returns can be achieved by the swarm based architecture and the risk tolerance afforded by the utilization of large numbers of low-cost sensor carriers. This study found a potential architecture that could reduce the cost of replicating Cassini by as much as 63%. The results of this investigation are not constrained to Saturn and can be easily translated to other targets such as Uranus, Neptune or the asteroid belt.

Full textAbstract:
The National Aeronautics and Space Administration maintains a challenging schedule of planned and on-going space exploration missions that extend to the outer reaches of our galaxy. New missions represent a huge investment, in terms of actual costs for equipment and support infrastructure, and personnel training. The success of a mission is critical considering both the monetary investment, and for manned missions, the lives which are put at risk. Tragedies involving Challenger, Columbia, Apollo 7, and the near tragedy of Apollo 13 exemplify that space exploration is a dangerous endeavor, posing extreme environmental conditions on both equipment and personnel. NASA, the National Science Foundation and numerous independent researchers indicate that predictive simulations have the potential to decrease risk and increase efficiency and effectiveness in space exploration activity. Simulations provide the capability to conduct planning and rehearsal of missions, allowing risk reducing designs and techniques to be discovered and tested. Real-time simulations may improve the quality of the response in a real-time crisis situation. The US Army developed Layered Terrain Format (LTF) database is a uniquely architected database approach that provides high fidelity representation of terrain and specialized terrain query functions that are optimized to support real-time simulations. This dissertation investigates the question; can the unique LTF database architecture be applied to the general problem of celestial body representation? And if so, what benefits might it bring for mission planners and personnel executing the mission? Due to data limitations, this research investigates these questions through a lunar analog setting involving S band and Earth-bound communication signals as might be needed to conduct manned and/or robotic mission on the moon.; The target terrain data set includes portions of the Black Point Lava Flow in Arizona which will be used for NASA's 2010 Desert RATS analog studies. Applied Research Associates Inc, the developer of the LTF product, generated Black Point databases and made limited modifications to the LTF Viewer tool, RAVEN, which is used for visualization of the database. Through the results attained during this research it is concluded that LTF product does provide a useful simulation capability which could be used by mission personnel both in pre-mission planning and during mission execution. Additionally, LTF is shown to have application an information system, allowing geo-specific data of interest to the mission to be implemented within its layers.

Spencer, Ronald L. "Implementing international standards for "continuing supervision"." Thesis, McGill University, 2008. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=111581.
Full textAbstract:
The Outer Space Treaty established the obligation to provide continuing supervision of its national space activities by the appropriate state. The implementation of this obligation remains a matter of state discretion. Since this Treaty came into force the world has evolved to become reliant on space based utilities to enable the global economy and state governance. Today, space faring states are increasingly dependent upon the supervision practices of other states to assure its space interests as the attribution of state responsibility becomes more difficult to ascribe.Therefore, the absence of binding supervision standards may become an impediment to future space applications due to three identified trends. First, the trend towards space commercialization requires active state supervision. Second, the rise in environmental hazards requires minimal safety standards to decrease the harmful effects on space applications. Third, space security requires identification of intentional acts and prudent measures to safeguard vital space applications.

Statham, Shannon M. "Autonomous structural health monitoring technique for interplanetary drilling applications using laser doppler velocimeters." Diss., Georgia Institute of Technology, 2011. http://hdl.handle.net/1853/39488.
Full textAbstract:
With the goal to continue interplanetary exploration and search for past or existent life on Mars, software and hardware for unmanned subsurface drills are being developed. Unlike drilling on Earth, interplanetary exploration drills operate with very low available power and require on-board integrated health monitoring systems, with quick-response recovery procedures, under complete autonomous operations. As many drilling faults are not known a priori, Earth-based direction and control of an unmanned interplanetary drilling operation is not practical. Such missions also require advanced robotic systems that are more susceptible to structural and mechanical failures, which motivates a need for structural health monitoring techniques relevant to interplanetary exploration systems.
Structural health monitoring (SHM) is a process of detecting damage or other types of defects in structural and mechanical systems that have the potential to adversely affect the current or future performance of these systems. Strict requirements for interplanetary drilling missions create unique research problems and challenges compared with SHM procedures and techniques developed to date. These challenges include implementing sensors and devices that do not interfere with the drilling operation, producing "real-time" diagnostics of the drilling condition, and developing an automation procedure for complete autonomous operations.
Thus, the completed thesis work presents basic research leading to the dynamic analysis of rotating structures with specific application to interplanetary subsurface drill systems, and the formulation of an autonomous, real-time, dynamics-based SHM technique for drilling applications. This includes modeling and validating the structural dynamic system, with and without damage or faults, for a prototype interplanetary subsurface drill, exploring the use of Laser Doppler Velocimeter sensors for use in real-time SHM, developing signal filters to remove inherent harmonic components from the dynamic signal of rotating structures, developing an automation procedure with the associated software, and validating the SHM system through laboratory experiments and field tests.
The automated dynamics-based structural health monitoring technique developed in this thesis presents advanced research accomplishments leading to real-time, autonomous SHM, and it has been validated on an operating dynamic system in laboratory and field tests. The formulated SHM and drilling operation also met or exceeded all specified requirements. Other major contributions of this thesis work include the formulation and demonstration of real-time, autonomous SHM in rotating structures using Laser Doppler Velocimeter sensors.

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Physics, 2004.Includes bibliographical references (p. 59).
In this thesis, I discuss the Brans-Dicke theory of gravitation, the Higgs mechanism, and the relevance of these two theories to the bridging of cosmology and particle physics. Although the former theory is in the field of cosmology while the latter is in particle physics, their similarities are impressive. Both attempt to understand the origins of mass. Even more striking is the mathematics involved in each of these theories. The Brans-Dicke theory and the Higgs mechanism both introduce a new scalar field that is coupled to matter in the universe. Although these theories were formulated around the same time in the early 1960s, are so similar in motivation and method, and became quite popular in their own respective fields, they remained relatively unknown outside of their field for quite some time. In this thesis, I have summarized both the Brans-Dicke theory and the Higgs mechanism. Then, I have analyzed the number of articles citing the Brans-Dicke and Higgs papers to understand when particle physics and cosmology first began integrating. To extend this further, I have looked at how many articles in 1961, 1971, 1981, and 1991 can be categorized as both particle physics and cosmology. In conclusion, we see that the two fields were slow to build common ground, although this has improved since the 1980s. By the 1990s, collaboration between particle physics and cosmology had greatly increased, most likely because of attempts to unify gravity with the other three forces.

Full textAbstract:
Private entities, investing billions of dollars, as a matter of reasonable commercial corporate expectations, want to be protected against undue use, exploitation and copying of their technology and inventions which they have put into their space ventures (often termed as 'theft') by any third party. States, to secure an environment friendly to such generation, use and transfer of intellectual property rights (IPRs) in outer space, have initiated applying and/or extending their national IP laws into outer space either in form of a statute or a multilateral agreement. This may have both commercial and political significance.This thesis deals with IP issues in international perspective (with reference, however, to some leading national IP legislation when and where it is necessary) with special reference to the contemporary legal regime governing outer space. While emphasizing the existing legal regime relating to IPRs in outer space, it explores the possibility of commercial exploitation of IPRs made in space and on ground through the existing international trade system. The increasing importance of cooperation between the World Intellectual Property Organization and World Trade Organization in this regard is also examined, against the back drop of space activities and the outer space legal regime relating to IPRs.

Full textAbstract:
One of the most prominent trends of our time is the emergence of an information society. The amount of data available is absolutely surging, at the same time as we are becoming more and more dependent on constant access to updated and relevant information. To derive high quality information from a large quantity of textual data, we need efficient methods for structuring and querying the data. One way is to use the Vector Space Model (VSM), a mathematical way of representing the relationship between words and documents. Wellknown examples of this approach are Latent Semantic Indexing (LSI) and Random Indexing (RI). This thesis describes the implementation of an information retrieval system based on the VSM that uses fragments of parse trees to index data.

Full textAbstract:
Satellite telecommunications, global navigation and remote sensing systems are key drivers in the ongoing transformation of an industrial based global economic order to one increasingly dominated by information services. A growing number of States are establishing an independent presence in outer space and all States (and indeed, individuals) can access a broad range of affordable space-related products and services (e.g., Google Earth imagery, GPS receivers, and global voice and data transmissions). Consistent with broad historical trends, these technologies are inevitably influencing the way States think about, plan for, and conduct warfare. Inspired by the prospect of seizing the ultimate "high ground" of outer space and achieving "information superiority" over an enemy, militaries around the world are rapidly pursuing independent space capabilities and adapting their strategies, doctrine and force structures to reflect these capabilities. These trends have prompted various political and legal efforts to ban the placement and/or use of weapons in outer space. As these efforts have failed to gain traction and seem unlikely to do so in the foreseeable future, this thesis argues that existing bodies of international law grounded in a pragmatic acceptance of armed conflict must be consulted if humankind wishes to mitigate the impact and spread of warfare conducted in, from and through outer space. In particular, this thesis will examine how the traditional customary principles underlying the law of neutrality may be reconceptualized by States to serve as a mechanism to mediate competing claims of belligerents and neutrals during armed conflict in outer space. After a brief introduction, Chapters One and Two will develop the economic and military trends discussed above. Chapter Three will provide an overview of the relevant international law governing military activities in outer space. Chapter four will analyze the law governing State responsibility for outer space activities to determine which State(s) will bear primary international responsibility for satellite support provided to belligerents during armed conflict. Chapter Five will provide a detailed overview of the law of neutrality and attempt a preliminary analysis of how belligerent and neutral States may seek to adapt this law to suit their interests during armed conflict in outer space. Concluding that the law of neutrality may serve to mitigate the impact and spread of armed conflict in outer space, this thesis offers various proposals designed to facilitate the application of this law.

Full textAbstract:
After the end of the Cold War, a dramatic swift has been observed in the space activities of States. Whereas in the beginning the various space programmes where more peace-oriented, the increased commercialization of outer space led to the need to increase defensive technology in space as well. The problems arising out of the intensified militarization of outer space over the last decades form part of the analysis of the present Thesis. The interrelation of general international law and of space law is at the background of all relevant argumentation presented in this paper. The modern trends in State practice are also presented and analysed, within the context of the current legal regime. Suggestions and comments on the different proposals presented for solving the problems, real or fictional, of space law, have been included in the Thesis.The conclusion drawn from the research performed for the writing of this paper indicates that the current legal regime governing space law is sufficient for the regulation of almost all issues created by modern technology. The only necessary change is that of a change of attitude and conviction of the States towards the law, and perhaps a few minor adjustments to address completely novel concepts.Après la fin de la guerre froide, une rapidité spectaculaire a été observée dans les activités spatiales des États. Alors que dans le début des programmes spatiaux différents, où plus orientée vers la paix, la commercialisation accrue de l'espace a conduit à la nécessité d'accroître la technologie de défense dans l'espace aussi bien.Les problèmes découlant de l'intensification de la militarisation de l'espace au cours des dernières décennies font partie de l'analyse de la présente thèse. L'interrelation entre le droit international général et le droit de l'espace est au fond de tous les arguments pertinents présentés dans ce document.Les tendances modernes dans la pratique des États sont également présentées et analysées dans le contexte du régime juridique actuel. Suggestions et commentaires sur les différentes propositions présentées pour résoudre les problèmes, réels ou fictionnels, de droit de l'espace, ont été inclus dans la thèse.La conclusion tirée de la recherche effectuée pour la rédaction de ce document indique que le régime juridique actuel régissant le droit spatial est suffisant pour la réglementation de presque tous les problèmes créés par la technologie moderne. Le seul changement nécessaire est celle d'un changement d'attitude et la conviction des États envers la loi, et peut-être quelques ajustements mineurs à l'adresse des concepts totalement inédits.

This dissertation concerns the role of place in scientific practice. Ideas of place, I argue, shape and are shaped by science. I specifically look at the community of planetary scientists who, though they cannot step foot on the objects they study, transform planets into places. This is an ethnographic work that draws on 18 months of fieldwork during which time I encountered several different communities of planetary scientists. At MIT, I worked alongside astronomers looking for planets around other stars. These "exoplanet" astronomers transformed numerical counts of photons into complex worlds with atmospheres and weather. Data visualizations characterized the work of a community learning to see unseen planets in specific, place-based ways. I also traveled with an astronomer to a Chilean observatory where she studied the night sky hoping to find a "habitable planet." Many other astronomers share this goal and have designed various ways to detect a planet like Earth. The importance of these projects signifies that exoplanet astronomers are more interested in finding planetary kin - planets that are familiar places - than exotic aliens. To determine how the planetary places created by exoplanet astronomers differ from those in our own Solar System, I spent time at the NASA Ames Research Center with a group of computer scientists who create high resolution and three-dimensional maps of Mars. These maps reflect the kind of place Mars is today: it is available to everyone to explore, it is displayed such that you can imagine standing on the surface, and it is presented as geologically dynamic in ways similar to Earth. Even though these maps help give Mars a sense of place, Martian science is still stymied by the inability to send humans to its surface. Instead, planetary scientists travel to terrestrial sites deemed to be "Mars-like" to approximate performing geologic fieldwork on Mars. I went to one of these locations to see how, during these outings, Mars and Earth become entwined as scientists forge connections between two planetary places. These diverse scientific activities, I conclude, are transforming our view of the cosmos. Outer space is becoming outer place.

Full textAbstract:
The politics of outer space has in recent years been given attention from political elites and scientist due to increasing usage and reliance on space based assets, and due to increasing numbers of actors trying to utilize the benefits of space. Concerns have been raised if the increasing military usage of space will lead to a future weaponization of space, making some political leaders and scholars claiming the inevitability of space weaponization. In this thesis I investigate why the United States of America this far has chosen not to weaponize space based on the strategical setting of outer space politics. The research question guiding this thesis reads: What strategic considerations explain the US decision not to weaponize outer space? In order to evaluate the strategic setting and US strategical considerations I apply Game Theory and Non-Formal Rational Choice Theory to highlight what is causing the greatest space faring nation not to weaponize space. I empirically base this study on official space policy documents and one report written by an official commission to asses US national security space management. Based on the strategic setting of outer space politics and US strategical considerations it is found that the US has not commenced a process leading to the weaponization of space since such development would not increase its national security, but rather in several ways decrease it. I conclude that a process of space weaponization is not likely to be initiated by the US in the current strategical setting.

This thesis explores the intersection of folkloric ritual theory and popular culture, expressed in science fiction television. The three-part rite of passage model established by folklorist Arnold van Gennep and later expounded upon by anthropologist Victor Turner is used as an analytical tool to establish the themes and structures of two popular television programs, Battlestar Galactica and Doctor Who. Both contain structures that resemble a rite of passage and exhibit a particular feature of the liminal stage of a rite of passage: ludic recombination. In the discussion of Battlestar Galactica, the plot arc of the entire series is analyzed as a rite of passage. On Doctor Who, the ritual model is examined as a structural component of the "companion" character. The structure and features of rites of passage allow science fiction narratives to explore sociocultural issues and existential themes in a meaningful way.

Full textAbstract:
This thesis investigates the European Union’s (EU) conceptualisation of outer space security in the absence of clear borders or boundaries. In doing so, it analyses the means the EU undertakes to secure the space segments of its critical outer space infrastructures and the services they provide. The original contribution to knowledge offered by this thesis is the framing of European outer space security as predicated upon anticipatory mechanisms targeted towards critical outer space infrastructures. The objective of this thesis is to contribute to astropolitical literature through an analysis of the EU’s efforts to secure the space segments of its critical outer space infrastructures, alongside a conceptualisation of outer space security based upon actor-specific threats, critical infrastructures and anticipatory security measures. The EU’s Galileo and Copernicus programmes are identified as future critical outer space infrastructures through their services’ expected contributions to EU-level policy-multiplication and European states and societies, making them examples of regional and global European space power projection. Following the designation of the Galileo and Copernicus programmes as critical outer space infrastructures, the thesis details the dangers and risks, both intentional and environmental, which the EU has publicly acknowledged as being the most threatening. Although the specific risk assessments for the Galileo and Copernicus projects are confidential, the generic dangers and risks for satellites in Lower Earth Orbit and Middle Earth Orbit referred to in EU policy documents are explored, including space debris, space weather phenomena, orbital congestion and the possibility of the future weaponisation of near-Earth space.

Typical design for manufacturing applications requires simultaneous optimization of conflicting performance objectives: Design variations that improve one performance metric may decrease another performance metric. In these scenarios, there is no unique optimal design but rather a set of designs that are optimal for different tradeoffs (called Pareto-optimal). In this thesis, I present a novel approach to discovering the Pareto front, allowing designers to navigate the landscape of compromises efficiently. The approach is based on a first-order approximation of the Pareto front, which allows entire neighborhoods rather than individual points on the Pareto front to be captured. In addition to allowing for efficient discovery of the Pareto front and the corresponding mapping to the design space, this approach allows one to represent the entire trade-off manifold as a small collection of patches that comprise a high-quality and piecewise-smooth approximation. Additionally, I will present the early stages of an extension to the aforementioned work - namely the capability to discover a Pareto gamut that arises from multiple fronts affected by one or more application variables.

Full textAbstract:
Molti problemi rimangono aperti riguardo il gruppo degli automorfismi di un gruppo libero finitamente generato, primo fra tutti il problema del coniugio e la sua decidibilità. Un ottimo modo per studiare un gruppo è trovare uno spazio con buone proprietà su cui questo agisca e realizzarlo quindi come gruppo di simmetrie di tale spazio. Su quest’onda l’Outer Space nasce dall’esigenza di studiare il gruppo degli automorfismi di un gruppo libero finitamente generato.
Questo spazio ha molte analogie con lo spazio di Teichmuller di una superficie, che parametrizza le strutture complesse su di essa. Un punto dell'Outer space relativo al gruppo libero su n elementi è sostanzialmente dato da un grafo metrico con gruppo fondamentale isomorfo a quest'ultimo e un fissato isomorfismo. Il gruppo degli automorfismi del gruppo libero su n elementi agisce sull'Outer space modificando questo isomorfismo. Per poter studiare il gruppo degli automorfismi di un gruppo libero finitamente generato mediante l'Outer space è utile conoscere alcune basilari proprietà geometriche di quest'ultimo. In questo elaborato ne dimostriamo la contraibilità.

Nearly fifty years have passed since the beginning of the space age, but international lawmakers have yet to determine where airspace ends and outer space begins. This paper examines the need to settle the boundary dispute, specifically taking into account the effect it has on emerging technologies and the 'new' space industry.The opening chapter examines the fundamental changes that have occurred since the beginning of the space age, both in terms of the technology and the space exploration infrastructure. The background of the delimitation question is then provided, followed by a discussion of the legal significance of the boundary issue. The final chapter analyzes the spatialist and functionalist approaches to the delimitation of outer space, looking at the pros and cons of each position.

Full textAbstract:
The purpose of the thesis is to explore to what extent, if any, has the principle of the common heritage of mankind been implemented in the practice of states and in what areas. With that objective in mind, various fields of international law are critically canvassed, including the Antarctic Treaty, the Outer Space Treaty and the U.N. Convention on the law of the Sea, plus such international organizations as the European Space Agency and INMARSAT, all with the view to finding the best model for the application of the principle of the Common Heritage of Mankind to Outer Space. The thesis recommends the establishment of a special outer space organization as the best way to satisfy the needs of the developing countries and their expectations.

Full textAbstract:
This thesis explores the institutional and cultural development of the British Interplanetary Society (BIS) and its influence in wider cultures of ‘British outer space’ in the mid-twentieth century. The Society was founded in 1933 in Liverpool by P E Cleator, and having attracted a small group of enthusiastic members before the outbreak of the Second World War, successfully re-grouped after the conflict and grew to become one of the most influential of all the space flight societies by the 1960s. The thesis starts by examining the ways in which the discipline of geography has recently started to re-engage with outer space as a field of enquiry, and suggests that geopolitical and cultural approaches to studying outer space would be a productive academic pursuit. The empirical chapters start by looking at the institutional cultures of the BIS, and explore the relationship between the Society and the production of interplanetary knowledge. The Society’s global connections and internationalist stance are also brought into focus, with contrasting accounts identified before and after the war raising questions about the geopolitics of British outer space. The empirical chapters go on to study how the BIS became connected to the wider world of popular culture in Britain, examining imaginative and amateur representations and performances. This section includes analyses of certain science fiction texts, including the selected novels of Olaf Stapledon, Arthur C Clarke and C S Lewis, and also considers Frank Hampson’s Dan Dare space adventure comics and the long-running television series The Sky at Night, whilst maintaining an empirical connection to the BIS throughout. The thesis closes with a discussion of what it means to bring together materials from both institutional and popular cultures, in the context of the emerging research area of the geographies of outer space.

Full textAbstract:
The uncontrolled growth of the space debris population is an environmental challenge. The several major debris-generating events at the beginning of the 21st Century suggests that the existing space governance regime encourages self-interested, rational state and non-state space actors to freely access and make use of the extraterrestrial commons without credible restraint, and lacks the robustness to hold these entities directly accountable and liable for their polluting activities. Such non-discriminatory right encourages these users to act and behave individualistically when utilising outer space, and make irresponsible choices like decisions to carry out debris-creating activities. These events also show that actors are tied together in a lattice of interdependence so long as they continue to share the space environment. An irresponsible operator who carries out an unsafe, risky activity increases the environmental costs shared by all members, both current and future users. The debris problem is an externality produced by human activities in space which can over time create a type of social dilemma called the ‘Tragedy of the Commons’ - a situation involving the environmental degradation and possible ruin of a shared resource. Many conferences have emphasised the seriousness of space congestion, and technological efforts have been adopted to reduce environmental degradation. However, while they are practical in the short and medium term, these measures lack the capacity to offer long-term solutions to deal with the problem. Often overlooked is a scrutiny on the adequacy of the existing space governance regime to preserve the space environment and control the debris population. The focus has been on exploration and exploitation and less on actively regulating the actions and behaviours of space actors when appropriating the resource, and restraining those strategic choices users would take in given situations. This thesis considers the shortcomings of the current outer space regulatory regime and proposes alternative space governance arrangements. It uses insights from the works of two property-rights theorists: Garrett Hardin and Elinor Ostrom – who developed the most widely used institutional designs to manage terrestrial and small-scale common-pool resources. They argue that resource users cannot efficiently coordinate collective action to deal with social dilemmas because of its institutional arrangement, and that such regime must be redesigned. However, their policy prescriptions are competing. Hardin states that the commons should be either privatised or managed by an external authority. Ostrom, on the other hand, argues that community-based governance can be successful when certain conditions are satisfied. From their respective works, this thesis constructs theoretical frameworks to determine if either Hardin’s or Ostrom’s prescriptions can be so crafted to provide an alternative space governance regime, and address the space debris problem. If the proposed institutional arrangement is appropriate and viable to govern outer space, it offers considerations on what further must be done to ensure its robustness to effectively regulate access and oversee the use of the space environment; restrain actors from carrying out potentially harmful activities; and organise actors to resolve collective action problems.

Full textAbstract:
Space technologies are becoming increasingly indispensible for modern societies and militaries around the globe, through a heightened dependency on satellite based services. At the same time, anti-satellite weapons are being developed and tested with the capacity to attack and destroy a satellite with precision. In the light of this development, the legal uncertainty on what rules apply to belligerent use of force in the realm of outer space is problematic. Since dual-use satellites do not enjoy explicit special protection in international law, it is relevant to clarify what legal protection they do hold, being objects enabling indispensable societal services. Would state practice and hostile space conduct prevail clarification, a fatal international custom might develop, and the difficulty of reaching agreements regulating attacks on satellites, along with other hostile behavior, enhanced. The purpose of this thesis is to investigate what the current frameworks of space law and international humanitarian law provide in terms of restraints to states’ legal possibilities to attack dual-use satellites in times of armed conflict. It is concluded that both frameworks do hold restrictions respectively. Though, the need for regulation is still evident in order to achieve a clear and foreseeable legal reality along with a sustainable future of space exploration where international peace and security can be maintained.

As processors scale deep into the multi-core and many-core regimes, bandwidth and energy-efficiency of the on-die interconnect network have become paramount design issues. Recognizing potential limits of electrical interconnects, emerging nanophotonic integration has been recently proposed as a potential technology option for both on-chip and chip-to-chip applications. As optical links avoid the capacitive, resistive and signal integrity limits imposed upon electrical interconnects, the introduction of integrated photonics allows for efficient realization of physical connectivity that are costly to accomplish electrically. While many recent works have since cited the potential benefits of optics, inherent design tradeoffs of photonic datapath and backend components remain relatively unknown at the system-level. This thesis develops insights regarding the behavior of electrical and hybrid optoelectrical networks and systems. We present power and area models that capture the behavior of electrical interface circuits and their interactions with optical devices. To animate these models in the context of a full system, we contribute DSENT, a novel physical modeling framework capable of estimating the costs of generalized digital electronics, mixed-signal interface circuitry, and optical links. With DSENT, we enable fast power and area evaluation of entire networks to connect the dynamics of an underlying photonics interconnect to that of an otherwise electrical system. Using our methodolody, we perform a technology-driven design space exploration of intra-chip networks and highlight the importance of thermal tuning and parasitic receiver capacitances in network power consumption. We show that the performance gains enabled by photonics-inspired architectures can enable savings in total system energy even if the network is more costly. Finally, we propose a photonically interconnected DRAM system as a solution to the core-to-DRAM bandwidth bottleneck. By attacking energy consumption at the DRAM channel, chip, and bank level with integrated photoncis, we cut the power consumption of the DRAM system by 10x while remaining area neutral when compared to a projected electrical baseline.

The present thesis describes the PhD research activities dealing with the topic “Space Exploration Systems, Strategies and Solutions”.
Traveling beyond low Earth orbit is the next step in the conquest of the solar system and so far, a human expedition to Mars is considered the most interesting goal of future human space exploration. Due to the technological and operational challenges associated with such a mission, it is necessary to define an opportune path of exploration, relying on many missions to intermediate and “easier” destinations, which would allow a gradual achievement of the capabilities required for the human Mars mission.
The main scope of this research has been the development of a rigorous and versatile methodology to define and analyze evolutionary exploration scenarios and to provide a detailed technologies’ database, to support strategic decisions for human space exploration. The very innovative aspect of this work regards the development of a flexible methodology which can be followed to assess which are the next destinations for the exploration of space beyond LEO and to preliminarily define mission’s architectures, identifying the most significant needed elements and advanced technologies. The obtained results should be seen as a pure technical reference, as no cost and/or political considerations have been included, and can be exploited to opportunely drive the decisions of the agencies to place investments for the development of specific technologies and get ready for future exploration missions.
The first part of the work has been devoted to the definition of a reference human space exploration scenario, which relies on both robotic and human missions towards several destinations, pursuing an increasing complexity approach and looking at a human expedition to Mars as final target. The scenario has been characterized through the assessment of the missions and
the relative phases and concepts of operations. Accordingly, the needed space elements, or building blocks, have been identified. In this frame, the concept design of two specific elements has been performed: the first is a pressurized habitation module (Deep Space Habitat) for hosting astronauts during deep space missions; the second is an electrical propulsive module (Space Tug), mainly envisioned for satellites servicing. The last part of the work has focused on the analysis of innovative and enabling technologies, with particular attention to the aspects related to their on-orbit demonstration/validation, prior to their actual implementation in real exploration missions.
The PhD has been sponsored by Thales Alenia Space - Italy and the overall work has been performed in different frameworks along the three years, as well as participating to several additional activities.
In line with the objectives of the PhD, in 2012 a collaboration between Politecnico di Torino and Massachusetts Institute of Technology has been established (MITOR Project, managed by MIT-Italy Program), with the support of Thales Alenia Space as industrial partner. The MITOR project, titled “Human Space Exploration: from Scenario to Technologies”, has been aimed at identifying and investigating state of the art for Human Space Ex- ploration, enabling elements, subsystems and technologies with reference to a selected scenario and relevant missions and architectures. Part of the nine months activities has been carried out at MIT AeroAstro department. Besides MITOR project, the PhD activities have been carried out in synergy with some other research programs, such as ESA “Human Spaceflight & Exploration Scenario Studies” and STEPS2 project (Sistemi e Tecnologie per l’EsPlorazione Spaziale - phase 2).
Furthermore, in 2013 a specific study has been performed in collabora- tion with university “La Sapienza” (Rome), “Osservatorio Astrofisico di Torino” (Astrophysical Observatory of Torino) and DLR (Deutsches Zentrum fr Luft- und Raumfahrt) in Bremen; its main objective has been the analysis of an interplanetary cubesats mission, aimed at space weather evaluations and technologies demonstration.

Full textAbstract:
The purpose of this research is to examine the outer space governance regime and to identify key governance deficits which are arguably the main reason for the far-reaching proliferation of space debris in the outer space commons. To this end, the research initially inspects two of the existing global commons – the maritime and polar regions – their governing regimes, and the regulatory, legal, and political challenges encountered in each. The discussion on the connection between global governance deficits and the environmental tragedies within these domains aims to establish the conceptual foundation of this study. Based on this foundation, the research discusses legislative and regulatory dimensions of outer space governance and international responses to the challenges facing the outer space commons. It concludes with the examination of the space debris problem and potential policy responses to address this global environmental tragedy. In this regard, in the light of Ostrom’s design principles, an international treaty on space environment protection, a financial programme in managing the cost of debris removal programmes and maintenance of spatial resources, and an international space agency to coordinate these fields and provide substantial cooperation between space actors, are offered as fundamental steps to prevent the tragedy in outer space – the common heritage of mankind. Therefore, this research intends to contribute to the understanding of the space debris problem and its consequences for global welfare.

As the debate over demarcation between airspace and outer space remains unresolved, advancements in technology are bringing these two realms of flight closer than ever before. Rather than relying on traditional functional or spatial approaches to define the legal framework of flight, this paper proposes a completely new legal system based on orbital status known as "Orbit Law."The first chapter examines the functional versus spatial debate, and highlights those aspects of existing International Air Law and Space Law which may be useful to an Orbit Law regime. Chapter II studies the science bridging air flight with space flight, and proposes the standardization of safety requirements for all suborbital and orbital flights. Finally Chapter III outlines the new legal principles of Orbit Law, highlighting innovative submissions for suborbital and orbital flights, solutions to issues of liability, and "Open Skies" for all flights.

This Thesis aims to examine recent efforts of the developing countries, within the Legal Subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), to increase their participation in space activities and in particular, to develop their own indigenous space capabilities. The Thesis will demonstrate that the United Nations is not, given the present economic and political climate, the best forum within which the developing countries should try to develop space law.Chapter 1 examines the main problems facing the developing countries in the transfer of space technology from the technologically advanced states. Chapter 2 examines the legal basis of their claims for greater cooperation. Chapter 3 examines the present debate within COPUOS where the developing countries are attempting to further develop international space law to their advantage. Chapter 4 suggests alternative routes which should be considered by the developing countries in order to work towards greater cooperation which will meet their needs.

The European Space Agency’s (ESA’s) 241Am radioisotope power systems (RPSs) research and development programme is ongoing. The chemical form of the americium oxide ‘fuel’ has yet to be decided. The fuel powder will need to be sintered. The size and shape of the oxide powder particles are expected to influence sintering. The current chemical flow-sheet creates lath-shaped AmO2. Investigations with surrogates help to minimise the work with radioactive americium. This study has proposed that certain cubic Ce1-xNdxO2-(x/2) oxides (Ia-3 crystal structures with 0.5 < x < 0.7) could be potential surrogates for some cubic AmO2-(x/2) phases. A new wet-chemical-synthesis-based process for fabricating Ce1-xNdxO2-(x/2) with a targeted x-values has been demonstrated. It uses a continuous oxalate coprecipitation and calcination route. An x of 0.6 was nominally targeted. Powder X-ray diffraction (PXRD) and Raman spectroscopy confirmed its Ia-3 structure. An increase in precipitation temperature (25 °C to 60 °C) caused an increase in oxalate particle median size. Lath/plate-shaped particles were precipitated. Ce Nd oxide PXRD data was Rietveld refined to precisely determine its lattice parameter. The data will be essential for future sintering trials with the oxide where variations in its crystal structure during sintering will be investigated. Sintering investigations with micrometric CeO2 and Nd2O3 have been conducted to understand how AmO2 and Am2O3 may sinter. This is the first reported pure Nd2O3 spark plasma sintering (SPS) investigation. A comparative study on the SPS and the cold-press-and-sinter of CeO2 has been conducted. This is the first study to report sintering lath-shaped CeO2 particles. Differences in their sizes and specific surface areas affected powder cold-pressing and caused variations in cold-pressed-and-sintered CeO2 relative density and Vickers hardness. The targeted density range (85-90%) was met using both sintering techniques. The cold-press-and-sinter method created intact CeO2 discs with reproducible geometry and superior Vickers hardness to those made by SPS.

Full textAbstract:
This thesis addresses the legal and policy issues relating to what may be the most exciting prospect in the history of the human civilisation: the commercial exploitation of natural resources in outer space. The thesis is based on the hypothesis that such ventures are inhibited not by physical, technological and economic factors, but by the inadequacies and uncertainties present in the current body of space law and policy. Consequently, a new international legal framework and a policy consensus are required to provide a legal environment favourable for such a valuable and necessary development.
To substantiate this hypothesis, the thesis begins by establishing the economic necessity and technical feasibility of space mining today, an estimate of the financial commitments required. This is followed by a risk analysis of a typical commercial mining venture in space, identifying the economic and legal risks. This leads to the recognition that the legal risks must be minimised to enable such enormous financial commitments to be made.
What then follows is a detailed analysis of the legal framework for such activities as well as identifying the inadequacies of space law for the commercial exploitation of celestial resources. This is achieved through a discussion of the general principles of international space law, particularly dealing with state responsibility and international liability, as well as some of the issues arising from space mining activities. Much detail is devoted to the analysis of the content of the common heritage of mankind doctrine in international law and the effect of international disagreement over its application to celestial bodies.
Having established the relevant legal issues, the thesis then turns to consider the past failures in reach similar agreements and the competing policy interests that have prevented the success of such agreements. It attempts to balance such interests in creating a legal and policy compromise that may be acceptable to a majority of the international community and provide some practical proposals on the structural, procedural, administrative and judicial aspects of creating and implementing a new legal framework.

Full textAbstract:
In the building automation domain, there are gaps among various tasks related to design engineering. As a result created system designs must be adapted to the given requirements on system functionality, which is related to increased costs and engineering effort than planned. For this reason standards are prepared to enable a coordination among these tasks by providing guidelines and unified artifacts for the design. Moreover, a huge variety of prefabricated devices offered from different manufacturers on the market for building automation that realize building automation functions by preprogrammed software components. Current methods for design creation do not consider this variety and design solution is limited to product lines of a few manufacturers and expertise of system integrators. Correspondingly, this results in design solutions of a limited quality. Thus, a great optimization potential of the quality of design solutions and coordination of tasks related to design engineering arises. For given design requirements, the existence of a high number of devices that realize required functions leads to a combinatorial explosion of design alternatives at different price and quality levels. Finding optimal design alternatives is a hard problem to which a new solution method is proposed based on heuristical approaches. By integrating problem specific knowledge into algorithms based on heuristics, a promisingly high optimization performance is achieved. Further, optimization algorithms are conceived to consider a set of flexibly defined quality criteria specified by users and achieve system design solutions of high quality. In order to realize this idea, optimization algorithms are proposed in this thesis based on goal-oriented operations that achieve a balanced convergence and exploration behavior for a search in the design space applied in different strategies. Further, a component model is proposed that enables a seamless integration of design engineering tasks according to the related standards and application of optimization algorithms.
