  1. The Space Object Ontology.Alexander Cox, Christopher Nebelecky, Ronald Rudnicki, William Tagliaferri, John L. Crassidis & Barry Smith - 2016 - In 19th International Conference on Information Fusion (FUSION 2016). IEEE.
    Achieving space domain awareness requires the identification, characterization, and tracking of space objects. Storing and leveraging associated space object data for purposes such as hostile threat assessment, object identification, and collision prediction and avoidance present further challenges. Space objects are characterized according to a variety of parameters including their identifiers, design specifications, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, processes, operational statuses, and associated persons, organizations, or nations. The Space Object Ontology provides a consensus-based realist framework (...)

  4. A Jesuit Against Galileo? The Strange Case of Giovanni Battista Riccioli Cosmology.Alfredo Dinis, Álvaro Balsas & Ricardo Barroso (eds.) - 2017 - Braga: Axioma - Publicações da Faculdade de Filosofia.
    This study aims to contribute to the research in the history of science, specifically, in the area of the seventeenth century cosmology, which had in Riccioli, a contemporary of Galileo, an undeniable protagonist. In many histories of science, Giovanni Battista Riccioli (1598-1671) is either omitted or mentioned only briefly in relation to his main cosmological work, the Almagestum Novum (1651), which is generally taken as little more than a source of useful information. When it comes to evaluating Riccioli’s philosophical views (...)

    Human beings have wondered about the stars since the dawn of the species. Does life exist out there – intelligent life, even – or are we alone? The quest for life in the universe touches on fundamental hopes and fears. It touches on the essence of what it means to formulate a theory, grasp a concept, and have an imagination. This book traces the history of the science of this area and the development of new schools in philosophy. Its essays (...)

  7. Complementary Inferences on Theoretical Physics and Mathematics.Mesut Kavak - manuscript
    I have been working for a long time about basic laws which direct existence, and some mathematical problems which are waited for a solution. I can count myself lucky that I could make some important inferences during this time, and I published them in a few papers partially as some propositions. This work aimed to explain and discuss these inferences all together by relating them one another by some extra additions, corrections and explanations being physical phenomena are prior.

  8. Tycho's Talisman: Astrological Magic in the Design of Uraniborg.Alistair Kwan - 2011 - Early Science and Medicine 16 (2):95-119.
    Renaissance Vitruvianism provides a broad context in which to situate the architecture of Tycho Brahe’s Uraniborg, but fails to account for the motivation behind Tycho’s design, for how Tycho knew Vitruvian design principles, and for any of Uraniborg’s specific features. Identifying Uraniborg as a Palladian design fares even worse. Some of Uraniborg’s features can, however, be understood in terms of talismanic ideas such as those circulating in sources such as Agrippa’s De occulta philosophia (which Tycho possessed) and Dee’s Propaedeumata aphoristica.

  9. Interstellar Transmitter Concept (King David’s Sling).Glen Monahan & Sarvraj Singh - 2013 - American Journal of Modern Physics 2 (3):138-143.
    A simple operating principle (similar to a combination of a pottery wheel and a catapult or, simply, the weapon used by David to slay Goliath) coupled with the success of some moderate engineering challenges may allow for the transmission of a carrier wave from Earth to Mars in less than one second! This paper also directly addresses the controversy of light speed variance/invariance (which has arisen from the “wave/particle nature of light” debate) by referencing Joseph A. Rybczyk’s 2012 paper, “Lunar (...)

    When the time comes to decide how to govern an extraterrestrial settlement there will be many alternatives to chose from. We will have the opportunity to try new and so far untested theories, but there are also some old forms of government that might be tempting to try again. We might for instance let the company whose activities on the world are the reason for the establishment govern the settlement. This has been tried before on our own planet both because (...)

    During antiquity, the astronomical questions of the day and the methods used to formulate and answer them were clearly within the realm of philosophy. That changed most notably in the sixteenth century when Tycho Brahe turned astronomy into a modern empirical science by formulating (in principle) testable hypotheses, figuring out how to test them, building the proper instruments, and making – for that time – very accurate and systematic observations of the sky. These observations eventually led to the modern view (...)

    If we eventually discover extraterrestrial life, do we have any moral obligations for how to treat the life-forms we find; does it matter whether they are intelligent, sentient, or just microbial—and does it matter that they are extraterrestrial? -/- In this paper, I examine these questions by looking at two of the basic questions in moral philosophy: What does it take to be a moral object? and What has value of what kind? I will start with the first of these (...)

    This paper presents an ontology architecture concept for the European Space Agency‘s (ESA) Space Situational Awareness (SSA) Program. It incorporates the author‘s domain ontology, The Space Situational Awareness Ontology and related ontology work. I summarize computational ontology, discuss the segments of ESA SSA, and introduce an option for a modular ontology framework reflecting the divisionsof the SSA program. Among other things, ontologies are used for data sharing and integration. By applying ontology to ESA data, the ESA may better achieve its (...)

  16. The Orbital Space Environment and Space Situational Awareness Domain Ontology – Towards an International Information System for Space Data.Robert J. Rovetto - 2016 Sept - In Proceedings of The Advanced Maui Optical and Space Surveillance Technologies (AMOS) Conference.
    The orbital space environment is home to natural and artificial satellites, debris, and space weather phenomena. As the population of orbital objects grows so do the potential hazards to astronauts, space infrastructure and spaceflight capability. Orbital debris, in particular, is a universal concern. This and other hazards can be minimized by improving global space situational awareness (SSA). By sharing more data and increasing observational coverage of the space environment we stand to achieve that goal, thereby making spaceflight safer and expanding (...)

CEUR Scientific Workshops.
    A short summary paper of my Orbital Space Domain Ontology project (purl.org/space-ontology), originally conceived in 2011. Since then I've sought (without success) opportunities to realize it (either as a PhD or other degree thesis; or in an employment position) toward my original passion of entering the space sector and gaining further space education. Since then persons in the relevant space disciplines have seen the potential in it, and unfortunately some have taken advantage of my ideas yet excluded me from work. (...)

  18. The Space Object Ontology.Robert J. Rovetto - 2016 - 2016 1.
    This paper develops the ontology of space objects for theoretical and computational ontology applied to the space (astronautical/astronomical) domain. It follows “An ontological architecture for Orbital Debris Data” (Rovetto, 2015) and “Preliminaries of a Space Situational Awareness Ontology” (Rovetto, Kelso, 2016). Important considerations for developing a space object ontology, or more broadly, a space domain ontology are presented. The main category term ‘Space Object’ is analyzed from a philosophical perspective. The ontological commitments of legal definitions for artificial space objects are (...)

    This paper defends, and emphasizes the importance of, spaceflight, broadly construed to include human and unmanned spaceflight, space science, exploration and development. Within this discourse, I provide counter-replies to remarks by physicist Dr. Steven Weinberg against my previous support of human spaceflight. In this defense of peaceful spaceflight I draw upon a variety of sources. Although a focus is human spaceflight, human and unmanned modes must not be treated as an either-or opposition. Rather, each has a critical role to play (...)

  20. An Ontological Architecture for Orbital Debris Data.Robert J. Rovetto - 2015 - Earth Science Informatics 9 (1):67-82.
    The orbital debris problem presents an opportunity for inter-agency and international cooperation toward the mutually beneficial goals of debris prevention, mitigation, remediation, and improved space situational awareness (SSA). Achieving these goals requires sharing orbital debris and other SSA data. Toward this, I present an ontological architecture for the orbital debris and broader SSA domain, taking steps in the creation of an orbital debris ontology (ODO). The purpose of this ontological system is to (I) represent general orbital debris and SSA domain (...)

  21. The Essential Role of Human Spaceflight.Robert J. Rovetto - 2013 - Space Policy 29 (4):225-228.
    The question is: should the United States and nations at large pursue a human spaceflight program (and if so, why)? I offer an unwavering positive answer to this question, and state the reasons for it while considering the broad challenges and benefits of (human) spaceflight. Space exploration is a human activity that is intrinsically forward-looking, and as such, has positive potential. Both national and international space programs can galvanize the population, inspire the youth, foster job-creation, and motivate the existing workforce. (...)

    Space situational awareness (SSA) is vital for international safety and security, and for the future of space travel. The sharing of SSA data and information should improve the state of global SSA for planetary defense and spaceflight safety. I take steps toward a Space Situational Awareness (SSA) Ontology, and outline some central objectives, requirements and desiderata in the ontology development process for this domain. The purpose of this ontological system is to explore the potential for the ontology research topic to (...)

    This article offers two arguments for the conclusion that we should refuse on moral grounds to establish a human presence on the surface of Mars. The first argument appeals to a principle constraining the use of invasive or destructive techniques of scientific investigation. The second appeals to a principle governing appropriate human behavior in wilderness. These arguments are prefaced by two preliminary sections. The first preliminary section argues that authors working in space ethics have good reason to shift their focus (...)

    Human space exploration requires massive budgets every fiscal year. Especially under severe financial constraint conditions, governments are forced to justify to society why spending so much tax revenue for human space exploration is worth the cost. The value of human space exploration might be estimated in many ways, but its social significance and cost-effectiveness are two key ways to gauge that worth. Since these measures should be applied country by country because sociopolitical conditions differ in each country and must be (...)

    Many global catastrophic risks are threatening human civilization, and a number of ideas have been suggested for preventing or surviving them. However, if these interventions fail, society could preserve information about the human race and human DNA samples in the hopes that the next civilization on Earth will be able to reconstruct Homo sapiens and our culture. This requires information preservation of an order of magnitude of 100 million years, a little-explored topic thus far. It is important that a potential (...)
