Development of 6DOF Hardware-in-the-Loop Ground Testbed for Autonomous Robotic Space Debris Removal

This paper presents the development of a hardware-in-the-loop ground testbed featuring active gravity compensation via software-in-the-loop integration, specially designed to support research in autonomous robotic removal of space debris. The testbed is designed to replicate six degrees of freedom (6DOF) motion maneuvering to accurately simulate the dynamic behaviors of free-floating robotic manipulators and free-tumbling space debris under microgravity conditions. The testbed incorporates two industrial 6DOF robotic manipulators, a three-finger robotic gripper, and a suite of sensors, including cameras, force/torque sensors, and tactile tensors. Such a setup provides a robust platform for testing and validating technologies related to autonomous tracking, capture, and post-capture stabilization within the context of active space debris removal missions. Preliminary experimental results have demonstrated advancements in motion control, computer vision, and sensor fusion. This facility is positioned to become an essential resource for the development and validation of robotic manipulators in space, offering substantial improvements to the effectiveness and reliability of autonomous capture operations in space missions.

Church Unity or Ecumenism: The Perspective of the United Congregational Church of Southern Africa 1967–2022

Right-wing politics is re-emerging all over the world, challenging the church to defy this trend and be true to her nature of oneness and Catholicism. This brings to the fore the question of unity and the ecumenical spirit. It is from this understanding that this article, which is an exercise in contemporary church history, seeks to contribute to the Reformed Church scholarship in the face of the current context of mission. The United Congregational Church of Southern Africa (UCCSA), as part of Reformed Churches, has a rich history of union. This discussion stems from the hermeneutical considerations of the reformed understanding of church unity, and particular focus is given to the UCCSA’s understanding of unity and ecumenism. After articulating what ought to be happening, the article delves into the historical considerations of the UCCSA and Church unity.

Designing Visual Displays for Deep Space Habitats: Challenges and Opportunities from a Cognitive Task Analysis with ISS Mission Control

This paper explores some challenges and opportunities in designing visual interfaces for deep space habitats with communication delays to Earth. The study first examines how Mission Control for the International Space Station (ISS) operates in detecting and responding to anomalous events. Interviews with participants who have held roles as flight controllers, backroom engineers, astronauts, or flight instructors for ISS and shuttle missions were conducted to gain insights into the responses to anomalous events. The collected anomalous scenarios were then re-considered under the context of deep space missions, where communication delays and other environmental factors are substantially different. Findings and insights on data analysis of the anomalous scenarios were then presented subsequently. Based on the findings, four areas of challenges and opportunities for visual interfaces design were identified. The paper suggests that these design challenges and opportunities be considered in more detail in future research.

ICACIA: An Intelligent Context-Aware framework for COBOT in defense industry using ontological and deep learning models

Most of the world’s most advanced defense technologies are robots, and the defence industry is slowly moving toward including AI in the military robots they build. For these smart robots to make their own decisions about where to go and what to do, they need to be limited by several algorithms that run continuously and at the same time. Autonomy is the range of automated systems that can be adapted to a specific mission, residual risk, and level of team cohesion between humans and robots. Self-driving robotic systems should be collaborative, which means they should be able to interact actively with humans in a shared space or in proximity to humans and robots. Human–Robot Collaboration (HRC) works better when these COBOTs are aware of their surroundings. Mobile Robot (MR) teams whose perceptual and cognitive abilities are very well developed can help a lot with context awareness. To work well with humans, these robots should know what is going on with their human and other robot teammates so they can make decisions on their own. Also, robots should be able to share information about their surroundings so that humans can benefit from a better understanding of the situation. At the same time, humans should be able to see what the robots are doing. In this paper, we propose a knowledge-based framework for humans and robots to work together to understand the context of Defense missions. An ontological model of contexts for missions, agents, and situations; a knowledge base comprising all the tools necessary for a sort of situation; and an efficient and reliable method of collaborative learning are some of its main contributions. The framework works well in terms of how long it takes for people to talk to each other. As the team continues to expand, it can also easily manage communication challenges and a widely differing event frequency range.

Managing and accessing web archives: Irish practitioners' perspectives.

This article provides practitioners’ perspectives on preservation of the Irish web space by the National Library of Ireland (the NLI). The context of this work is outlined including the history of Ireland’s national library, its role, resources and place in library, archive, cultural and digital preservation networks. The development of the NLI Web Archive is discussed within the wider context of the Library’s mission and digital collecting and preservation policies, as well as international approaches to preserving the web. The article looks at how the NLI has developed its selective web archive over the past decade, and has grown the content and access to it as a way to mitigate against the absence of at-scale solutions. The unusual legal context in Ireland regarding legislative barriers to archiving the Irish web space at scale and the NLI’s work for over a decade to change this situation are discussed as are the significant implications of the current legal situation for data loss and long-term access to Ireland’s contemporary record. Distinctive Irish aspects of digital cultural heritage preserved in the NLI Web Archive collections are highlighted. The opportunities and challenges in developing outreach and access for the Web Archive are considered together with its relationship with the collecting activities of the Library’s Born Digital Pilot Projects. This article will also discuss types of usage and user groups in relation to archived Irish web data. Potential for creative and imaginative uses of Irish web archive collections and data are also considered in relation to the Library’s broader public learning and outreach programmes.

The study of large-scale variability in total water storage within the context of modern satellite gravity missions

The analysis of Earth’s gravity field changes is the one of essential task of physical geodesy. So the knowledge about selected characteristics of gravity field is the basic element of the Earth shape determining process and help to find information about mass redistribution in the Earth system. Since 2002, the gravity field changes have been successfully observed by the Gravity Recovery and Climate Experiment (GRACE) satellite gravity mission and its continued GRACE-FO (GRACE Follow-On) mission. The results obtained from GRACE/GRACE-FO observations are presented, among other, in form of mascons and they are provid-ed by three processing centers: (1) Center for Space Research (CSR; Austin, United States), (2) Jet Propulsion Laboratory (JPL; Pasadena, United States), and (3) Goddard Space Flight Center (GSFC; Maryland, United States). In the following study, we used data provided by GSFC in form of the global distribution of Total Water Storage (TWS), which are expressed in terms of Equivalent Water Height (EWH). In our study, we focused on identifying areas with significant changes in TWS. We analysed TWS fluctuations in seasonal short-term changes, i.e., amplitude of annual oscillation (the most pronounced oscillation in the land hydro-sphere) and longterm changes, i.e., trend (a key parameter for climate studies) determined using the Least Squares Method. As a result, we selected 15 areas characterised by extreme TWS changes, i.e., 11 areas for annual amplitude and 4 areas for trend parameter. We obtained seasonal changes greater than 140 mm in areas within the equator (mainly Amazon, Niger, Ganges, Brahmaputra river basin regions) and areas covered by huge ice masses (Alaska, Greenland). The greatest rate of change in water storage at ±70 is observed around West Antarctica, Patagonia or the Caspian Sea. The results also emphasize the significant human impact in continental water masses (e.g. Mexico, Indus and Ganges river basins). Keywords: GRACE, TWS, land hydrology, gravity missions

Covid-19, Trends in Global Mission, and Participation in Faithful Witness

Mission is shaped by the life and experience of the church, both past and present, and this in turn is the function of both the work of the Spirit of God and the interaction of the people of God with their contexts. In line with this position, we examine the impact of Covid-19, highlighting some elements of the global context of mission, trends in world Christianity and mission. We then explore how global mission is in a process of realignment that has the potential to be enhanced through embracing the conditions Covid-19 has imposed on us. Finally, we consider the need for deep reflection on our identity if we are to take the opportunity to bear faithful witness in this moment.

Trends in Global Mission, Covid-19 and God’s Work among Muslims

Mission is shaped by the life and experience of the church, both past and present, and this in turn is the function of both the work of the Spirit of God and the interaction of the people of God with their contexts. In line with this position, we highlight some elements of the global context of mission, discuss trends in world Christianity and mission, then examine, as a historical case, the reported evidence of the work of the Spirit of God among Muslims. In exploring the evidence of the Spirit’s operation among Muslims, the paper reviews a selection of missionary sources, an autobiography of an illustrious Muslim convert and a selection of relatively recent secondary works. The underlying argument is that crises often lead to a search for new meaning and purpose, although not all of these may necessarily result in outward conversion and belonging. This should not discourage us, but rather be a source of rejoicing and a step towards partnership with God in his mission and ministry.

The isotopic composition of volatiles in the unique Bench Crater carbonaceous chondrite impactor found in the Apollo 12 regolith

Projectiles striking the Moon have modified its crust and delivered volatile elements to its interior and surface. Direct evidence of impactor origins is recorded by the rare occurrence of sub-cm sized meteorite fragments identified in Apollo samples and lunar meteorites. The Bench Crater meteorite is a millimetre-sized carbonaceous chondrite collected in regolith on the rim of Bench impact crater at the Apollo 12 landing site. Transmission electron microscopy has previously shown that Bench Crater contains abundant hydrated silicates, establishing the survivability of hydrated material impacting the lunar surface. To provide further information on the volatile inventory of the Bench Crater meteorite, we report here the isotope compositions of hydrogen, nitrogen, carbon and oxygen. This is the first direct isotopic analysis of meteoritic material delivered to the lunar surface and provides context for volatile and organic element signatures in lunar regolith samples, and the survivability of volatile material delivered to planetary surfaces during impact bombardment. The Bench Crater meteorite is characterised by δD values ranging between −36 ± 40 and 200 ± 40‰, and bulk average δ13C of −13 ± 30‰, and δ15N of −40 ± 36‰ (all uncertainties at the 2σ confidence level). The oxygen isotope compositions measured in situ in matrix silicates and magnetite in Bench Crater are consistent with those measured in matrix and magnetite in CI and CM chondrite falls. Altogether, these new H, C, N and O isotope data, coupled to mineralogical and geochemical observations, suggest that Bench Crater may have been derived from an asteroidal parent body not represented in the terrestrial meteorite collection. This is a crucial outcome in the current context of sample-return missions to carbonaceous asteroids, and more broadly for investigating the flux of material delivered to the Earth-Moon system through time.

힌두권의 소규모 비즈니스 선교(BAM) 다수 사례 연구

It has been 20 years since the concept of Business as Mission (BAM) was first introduced. BAM may be a good approach for the new context of cross-cultural missions today. This is a multiple case study, looking at 5 BAMs in a city in the Hindu world. Here are some findings. Concentrating on business in the early stage helped establish the business better. In the survival stage, paying attention to the needs of the market and customers provided more chance for survival. All BAMers in the study catered to the locals. The BAMers in the study did not have expertise in their business, but they sought and received help from experts and supporters. BAMers’ understanding of BAM was closely related to their ministry and the growth of their business.

‘True and Pious Men’: Anglican Ministry to Chinese Settlers in Southern Queensland, 1850–1914

Chinese men began emigrating to the Australian colonies from the 1840s onward. Past historiography has been sceptical of the impact of Christianity on these Chinese immigrants. This paper revisits this theme, placing it in the wider context of mission to Chinese immigrants in other anglophone countries. It documents the ministry of the Anglican Church among Chinese settlers in colonial Queensland, and especially the role that Chinese converts played in the evangelisation of their fellow countrymen. It provides a new perspective on the ways in which the Chinese embraced Christianity, and their contribution to the evangelisation of their countrymen.

Sunspot observation by the cooperation of amateur astronomers and researchers in Japan in early 20th century as early citizen science program

AbstractThe development of astronomy has been developed by the cooperation of amateur astronomers and researchers. Sunspot observation is a good example of Extreme citizen science in early days. Issei YAMAMOTO (1889–1959), organized “Oriental Astronomical Association (OAA),” Yamamoto’s materials (now in Kwasan observatory) include solar observation data sent from many observers in Japan. From the viewpoint of today’s Citizen Science, collaborative observation of sunspot between researchers of solar physics and amateur astronomers in Japan has clearly a context of social mission rather than mere academic interest. From the viewpoint of science communication, we can see that Yamamoto’s call includes a social mission to promote astronomy in Japan, and that amateurs responded to Yamamoto’s call by participating in the observation network. It can be said that this collaboration have not only “cultural” aspect but also “civic”or “practical” aspect.

Do Military Chaplains Preach? Exploring Sermons for Soldiers by Protestant Military Chaplains in the Dutch Army

The practice of Military Chaplains has been studied from various angles (sociological, historical, ethical) except from an empirical homiletical perspective. What do military chaplains do when they preach, if ‘preaching’ is the correct label for their (religious) speeches. This paper provides a first introduction to study the actual sermons of military chaplains in order to contribute to homiletical theory. It presents the outline of a research design and presents some of its initial results. The paper is based upon 10 sermons by army and naval chaplains within the context of peacekeeping missions. Three concepts emerge from these data, focussing upon the homiletical activity of military chaplains. They redefine the liturgical conditions for preaching, they witness to sources of wisdom, and they dignify the individual soldier in the presence of Christ. The paper closes with a proposal to understand religious discourse in the military context by presenting a tentative typology that is based upon the ceremonial setting of discourse and its religious referentiality.

Rendezvous design in a cislunar near rectilinear Halo orbit

ABSTRACTIn the context of future human spaceflight exploration missions, Rendezvous and Docking (RVD) activities are critical for the assembly and maintenance of cislunar structures. The scope of this research is to investigate the specifics of orbits of interest for RVD in the cislunar realm and to propose novel strategies to safely perform these kinds of operations. This paper focuses on far rendezvous approaches and passively safe drift trajectories in the Ephemeris model. The goal is to exhibit phasing orbit requirements to ensure a safe far approach. Ephemeris representations of Near Rectilinear Halo Orbits (NRHOs) were derived using multiple-shooting and adaptive receding-horizon targeting algorithms. Simulations showed significant drift and overlapping properties for phasing and target orbits of interest, motivating the search for safe natural drift trajectories and using impact prediction strategies.

Online or Face-to-Face: Do Mission-Related Student Learning Outcomes Differ?

This study investigated how an authentic assessment program was used to examine student learning outcomes within the context of a Christian university’s institutional mission, core values, and distinctive qualities. For the purposes of this study, an authentic assessment program is defined as assessing student-produced work within the context of the institutional mission. A sample of 1,814 undergraduate students taking one or more general education courses at the university during the 2007–2009 academic years was examined for any significant differences in student learning outcomes. A univariate analysis of covariance (ANCOVA) indicated the Student Assessment System (SAS) scores for the online students were not significantly different from the SAS scores for the face-to-face (F2F) students after controlling for course grade. These results suggest that online students achieved the same critical mission-related educational outcomes that the university required of its F2F students. An implication of this finding is that the university just as effectively articulated its faith-based mission and vision to the online students as it did to its students taking classes F2F.

Achieving resiliency in major defense programs through nonfunctional attributes

AbstractThis article examines how the ilities, or nonfunctional attributes, help to understand the concept of resiliency in engineered systems. For engineered systems, resiliency describes the ability of a system to react to and return to full function after an interruption to system operation. The literature on resiliency of engineered systems defines resiliency in both the context of mission and platform resiliency; however, it leaves an opportunity to research how to understand, manage, and achieve resiliency. This work proposes an application of the systems engineering ilities to resiliency to understand how systems engineers can account for resiliency in the design process and incorporate resiliency into systems. Quality, robustness, and agility assist in understanding the components of resiliency and the ilities of repairability, extensibility, flexibility, adaptability, and versatility provide means for systems to achieve resiliency. This article applies this framework to examine two cases of DoD systems, the B‐52 bomber and the F‐117 stealth fighter. These two examples demonstrate how nonfunctional attributes enable engineered systems to achieve resiliency and help to better understand the concept of resiliency in engineered systems.

Revisiting the Food and Agriculture Organization (FAO): International Histories of Agriculture, Nutrition,and Development

ABSTRACTAs far as international organizations and their written histories are concerned, the United Nations Food and Agriculture Organization, FAO, presents quite a paradox. Though in its early years, the organization itself as well as individual staff members were determined to document and narrate FAO's history, sixty years later many aspects of FAO's history remain largely unknown. The following articles re-examine the history of FAO through a range of new perspectives that shed light on the intellectual roots of rural development ideas within the organization and illuminate the context of specific development missions, as well as the transnational flows of knowledge and expertise.

Non-transport emergency medical service missions - a retrospective study based on medical charts.

In Finland, approximately 40% of emergency medical service (EMS) missions do not result in transport of the patient to a hospital by ambulance, and there is wide variability in the reasons underlying non-transport decisions. The aim of this study was to describe the context of these EMS non-transport missions. The data were collected retrospectively between 3 September and 20 October 2014 by investigating non-transport EMS charts (n=1154). Event information and patients' main symptoms were extracted from information found in EMS charts and quantified using content and statistical analyses. Patients' need for EMS were explained by various reasons. One-third of the missions were caused by organ-specific symptoms, whereas in 30.8% of cases the reason for EMS was unspecified. Sudden onset symptoms were noted for 38.4% of the cases, whereas in 14.7% of cases the symptoms had persisted for days or weeks before EMS contact. EMS personnel offered guidance instead of treatment in 79.2% of the missions. Non-transport missions represent a significant daily work load for the EMS. Although most of the symptoms showed acute onset, the majority of these missions involved only assessment of medical necessity and/or guidance without any medical treatment. It is questionable whether this use of the EMS is cost-effective for any healthcare system.
