It is now a National Historic Landmark and is being restored to a level that represents the day the ight control teams walked out after the last lunar landing missions. This is the story of human eorts, specically the innovation, struggle, and sacrice carried out by otherwise ordinary men and women, that culminated in the spacesuit that made the first human surface explorations of the Moon possible. During spaceight, human performance can be deeply aected by physical, psychological, and psychosocial stressors.

Endorsed by the International Association for the Advancement of Space Safety IAASS and drawing on the expertise of the worlds leading experts in the eld, this book is primarily centered on humans on board spacecraft but also covers operators of con trol centers on the ground and behavioral aspects of complex organizations, thus addressing the broad spectrum of space actors. Aerospace journalist Joe Pappalardo has wit nessed rocket launches around the world, visiting every working spaceport in the United States.

In his book Spaceport Earth Pappalardo describes the rise of a plethora of private companies in the United States and how they are reshaping the way the world is using space for industry and scienceand creating spaceports.

Kennedys plan to land humans on the Moon as the plan was summarized for a very limited number of people who were highly placed in the organizational structure. More than photographs from the archives of NASA are paired with extended captions detailing the science behind some of our cos mic neighborhoods most extraordinary phenomena.

In this book, the journey of understanding galaxies is told through the lens of the evolving use of images as investigative tools. Initial chapters explore how early insights developed in line with new methods of scientic imaging, particularly photography.

By examining developments in imag ing, this text places the study of galaxies in its broader historical context, contributing to both astronomy and the history of science. Space is the ultimate canvas for the imagination, and in the s and s, as part of the space race with the United States, the solar system was the blank page upon which the Soviet Union etched a narrative of exploration and conquest.

In this book, drawing on a comprehensive corpus of rarely seen photographs and other visual phenomena, the author maps the complex relationship between visual propa ganda and censorship during the Cold War. Explorer was the original American space program and Explorer 1 its rst satellite, launched in Sixty years later, the Explorer satellite program is the longest continuously running space program in the world, demonstrating to the world how we can explore the cosmos with small spacecraft. Almost a hundred Explorers have already been launched.

It introduces the launchers Juno, or, etc. From the selection of the Mercury astronauts in to the International Space Station missions of the 21st century, the training sequence has met the challenges of preparing astronauts for ight far more often than it has failed. Barber traces the origins of the V2 and presents a detailed view of the research conducted at the secret, experimental rocket-testing facility at Kummersdorf West and the vast, infamous base at Peenemnde.

Drawing on recently declassied documents from intelligence agen cies, the Department of Defense, the Federal Bureau of Investigation FBI , and the State Department, this book examines the process of integrating German scientists into a national security state dominated by the armed services and defense industries. History of Rocketry and Astronautics, Vol. This book contains the proceedings of the 49th History Symposium of the International Academy of Astronautics, Jerusalem, Israel, This book contains the proceedings of the 50th History Symposium of the International Academy of Astronautics, Guadalajara, Mexico, In the aftermath of the STS Space Shuttle Columbia tragedy, people and communities came together to help bring home the remains of the crew and nearly 40 percent of the Shuttle, an eort that was instrumental in piecing together what happened so the Shuttle Program could return to ight.

Bringing Columbia Home shares the deeply personal stories that emerged as NASA employees looked for lost colleagues and searchers overcame immense physi cal, logistical, and emotional challenges and worked together to accomplish the impossible.

In his message, Kennedy argued for Congress to provide the funding for the nation to be able to meet its goal of putting a man on the Moon and to invest in the space program to make such an event possible. Only a few years prior, on 4 October , the Soviet Union had launched the worlds rst articial satellite, Sputnik.

As the United States was preparing to make Alan Shepard the rst human in space, the Soviet Union was already a step ahead. Shepards launch aboard the Mercury-Redstone 3 capsule occurred three weeks later, on 5 May In light of this development, Kennedy argued that it was more important than ever to fund the edgling American space program: For while we cannot guarantee that we shall one day be rst, we can guarantee that any failure to make this eort will make us last But this is not merely a race.

Space is open to us now. I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth. Again, he urged the nation to con sider its role in the space race: We choose to go to the Moon. We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard, because the goal will serve to organize and measure the best of our energies and skills. Even today, he is remembered as the leader who asked the nation to send a man to the Moon Alan Shepard prepares for his Freedom 7 mission in His personal and politien-US -en-US cal desires for a lunar landing propelled decades of en-US spaceight and lunar activity, lasting long after his en-US death in Kennedy and the Race to the Moonen-US, p.

His investment in the space program had en-US little to do with personal curiosity about the solar en-US system or pushing the boundaries of technology, but en-US rather a burning political desire to beat the Soviets on en-US some front of the Cold War. Logsdon argues that Kennedy en-US pointed the nation toward the goal of a lunar landing, en-US not necessarily for the challenge, but possibly because en-US leaving the Moon to the Soviets was unthinkably en-US chilling.

Kennedy stressed that en-US sending astronauts to the Moon was vitally important en-US for international political reasons. What Logsdon does suggest is that backing o being the rst to the Moon did not seem to be on Kennedys mind in November In remarks he planned to deliver in Dallas on 22 November, Kennedy would have said, the United States of America has no inten tion of nishing second in space. It is important to recognize and remember Kennedy not just as a singularly minded visionary with a com petitive goal, but as a man torn between the pros and cons of a lunar landing program and a brewing Soviet relationship.

Kennedys ambitious proposal to the nation not only sparked Americas entrance into the space race, but also helped propel years of forward thinking and inspired a generation to fulll his goal of landing an American on the Moon. President John F. Webb, and Vice President Lyndon B.

Kennedy honors astronaut John Glenn after his historic rst crewed orbital ight on Friendship 7 in Its such a unique opportunity that its no wonder that, in the nearly six decades since space became accessible to humans, countless people have declared, When I grow up, I want to be an astronaut. To many students stuck in classrooms and adults stuck in cubicles, the prospect of going to space became additionally appealing once astronauts began tak ing eld trips to various places throughout North America.

Geological Surveys Branches of Astrogeology and Surface Planetary Exploration with the express intent of turning them into competent lunar scientists. For nearly 10 years January November leading up to and encompassing the rst and subse quent Apollo lunar landing missions Apollo 11 , astronaut crews trained to explore the Moon using PAGE 29 29 en-USthe only otherworldly environments they had access en-US to on Earth. Doing so allowed the astronauts en-US to experience and practice moving and operating with en-US the backpacks on, just as they would on the Moon.

In his opinion, eld work would make the bigen-US -en-US gest impact on how successfully the astronauts would en-US be able to execute their roles as the front-runners in en-US lunar geology. In his own words, the goal of the eld en-US trips was to expose them to as many dierent geologen-US -en-US ical experiences as we possibly could.

Get them out in en-US the elddont let them sit in the classroom. Who knows? Maybe the success of astronaut en-US eld trips on Earth could convince schools to keep en-US up their own eld trips, just like the overall success of en-US astronauts in space can convince people that they want en-US to be astronauts, too. To complement these existing discipline areas, a concept is presented focusing on the development of a space environments and spacecraft effects SENSE organization.

This SENSE organization includes disciplines such as space climate, space weather, natural and induced space environments, effects on spacecraft materials and systems and the transition of research information into application. These technical working groups will survey customers and users, generate products, and provide knowledge supporting four functional areas: design environments, engineering effects, operational support, and programmatic support. The four functional areas align with phases in the program mission lifecycle and are briefly described below. Design environments are used primarily in the mission concept and design phases of a program.

Engineering effects focuses on the material, component, sub- system and system -level selection and the testing to verify design and operational performance. Operational support provides products based on real time or near real time space weather to mission operators to aid in real time and near-term decision-making. The programmatic support function maintains an interface with the numerous programs within NASA, other federal. Life support is vital to human spaceflight, and most current life support systems employ single-use hardware or regenerable technologies that throw away the waste products, relying on resupply to make up the consumables lost in the process.

Because the long-term goal of the National Aeronautics and Space Administration is to expand human presence beyond low-earth orbit, life support systems must become self-sustaining for missions where resupply is not practical. From May through October , the life support team at the Johnson Space Center was challenged to define requirements, develop a system concept , and create a preliminary life support system design for a non-planetary Deep Space Habitat that could sustain a crew of four in near earth orbit for a duration of days.

Some of the preferred technology choices to support this architecture were passed over because the mission definition has an unmanned portion lasting days. The main portion of the architecture was derived from technologies currently integrated on the International Space Station as well as upcoming technologies with moderate Technology Readiness Levels.

The final architecture concept contains only partially-closed air and water systems , as the breakeven point for some of the closure technologies was not achieved with the mission duration. Some of the preferred technology choices to support this architecture were passed over as the mission definition also has an unmanned portion lasting days. A shuttle and space station manipulator system for assembly, docking, maintenance, cargo handling and spacecraft retrieval preliminary design. Volume 3: Concept analysis. Part 1: Technical. Information backing up the key features of the manipulator system concept and detailed technical information on the subsystems are presented.

Space station assembly and shuttle cargo handling tasks are emphasized in the concept analysis because they involve shuttle berthing, transferring the manipulator boom between shuttle and station, station assembly, and cargo handling. Emphasis is also placed on maximizing commonality in the system areas of manipulator booms, general purpose end effectors, control and display, data processing, telemetry, dedicated computers, and control station design.

Concept , design approaches suited to space nuclear power systems in the range of 20 kWE. Given the variety of possible missions and flight dates, it seems advisable to widen the basis for future technical choices within the French preliminary studies of kWe space nuclear power systems.

In addition to the fast spectrum, liquid metal-cooled reactor presently considered as a reference, shorter development term system , gas- and Na K -cooled thermal spectrum reactors are being investigated. The need for adequate ZrH moderator temperature conditions can be satisfied through a Brayton cycle conversion subsystem featuring two separate, high temperature-heat pipes and low temperature-pumped loop radiators. The penalty in efficiency and in radiator area, resulting from the wanted lower reactor inlet temperature, can be limited, particularly in the case of the higher temperature, gas-cooled reactor system.

A multiple, pivoting tubes, low temperature radiator concept is proposed; it avoids an extension of the related structural support frame beyond the conversion subsystem region in flight configuration. Arrangements peculiar to small reactors and two-turbo-generator diagrams for reliability reasons are presented. Provisional, not yet optimized, thermal management mass estimates are evaluated.

REARM could dramatically decrease the time and the expense required to launch new exploratory missions on Mars by making them less dependent on Earth and by reusing the assets already designed, built, and sent to Mars. REARM would introduce a new class of Mars exploration missions, which could explore much larger expanses of Mars in a much faster fashion and with much more sophisticated lab instruments. Equipment concept design and development plans for microgravity science and applications research on space station: Combustion tunnel, laser diagnostic system , advanced modular furnace, integrated electronics laboratory.

Taking advantage of the microgravity environment of space NASA has initiated the preliminary design of a permanently manned space station that will support technological advances in process science and stimulate the development of new and improved materials having applications across the commercial spectrum. Previous studies have been performed to define from the researcher's perspective, the requirements for laboratory equipment to accommodate microgravity experiments on the space station.

Functional requirements for the identified experimental apparatus and support equipment were determined. From these hardware requirements, several items were selected for concept designs and subsequent formulation of development plans. This report documents the concept designs and development plans for two items of experiment apparatus - the Combustion Tunnel and the Advanced Modular Furnace, and two items of support equipment the Laser Diagnostic System and the Integrated Electronics Laboratory.

For each concept design, key technology developments were identified that are required to enable or enhance the development of the respective hardware. Volume 2, Appendix C: Food cooling techniques analysis. Appendix D: Package and stowage: Alternate concepts analysis. The relative penalties associated with various techniques for providing an onboard cold environment for storage of perishable food items, and for the development of packaging and vehicle stowage parameters were investigated in terms of the overall food system design analysis of space shuttle.

The degrees of capability for maintaining both a 40 F to 45 F refrigerated temperature and a 0 F and 20 F frozen environment were assessed for the following cooling techniques: 1 phase change heat sink concept ; 2 thermoelectric concept ; 3 vapor cycle concept ; and 4 expendable ammonia concept. The parameters considered in the analysis were weight, volume, and spacecraft power restrictions. Data were also produced for packaging and vehicle stowage parameters which are compatible with vehicle weight and volume specifications.

Certain assumptions were made for food packaging sizes based on previously generated space shuttle menus. The results of the study are shown, along with the range of meal choices considered. Cross support overview and operations concept for future space missions. Ground networks must respond to the requirements of future missions, which include smaller sizes, tighter budgets, increased numbers, and shorter development schedules. The Consultative Committee for Space Data Systems CCSDS is meeting these challenges by developing a general cross support concept , reference model, and service specifications for Space Link Extension services for space missions involving cross support among Space Agencies.

This paper identifies and bounds the problem, describes the need to extend Space Link services, gives an overview of the operations concept , and introduces complimentary CCSDS work on standardizing Space Link Extension services. Laryngeal spaces and lymphatics: current anatomic concepts. This investigation evaluates the anatomic concepts of individual spaces or compartments within the larynx by isotope and dye diffusion. The authors identified continuity of spaces particularly within the submucosal planes and a relative isolation within the fixed structures resulting from the longitudinal pattern of fibroelastic tissues, muscle bands, and perichondrium.

The historical data of anatomic resistance are refuted by the radioisotope patterns of dispersion and the histologic evidence of tissue permeability to the carbon particles. There is little clinical application of the compartment concept to the perimeter of growth and the configuration of extensive endolaryngeal cancers. The internal and extralaryngeal lymphatic network is presented and the regional associations are identified. The normal ipsilateral relationship is distorted by dispersion within the endolarynx supervening the anatomic midline.

The effects of lymphatic obstruction caused by regional lymphadenectomy, tumor fixation, and irradiation-infection sequelae are illustrated; these result in widespread bilateral lymphatic nodal terminals. Finally, the evidence suggests that the internal network is modified by external interruption to accommodate an outflow system in continuity with the residual patent lymphatic channels. Mazanek, Daniel D. There exists an infrequent, but significant hazard to life and property due to impacting asteroids and comets.

There is currently no specific search for long-period comets, smaller near-Earth asteroids, or smaller short-period comets. These objects represent a threat with potentially little or no warning time using conventional ground-based telescopes. These planetary bodies also represent a significant resource for commercial exploitation, long-term sustained space exploration, and scientific research. A space -based detection system , despite being more costly and complex than Earth-based initiatives, is the most promising way of expanding the range of detectable objects, and surveying the entire celestial sky on a regular basis.

CAPS is a future spacebased system concept that provides permanent, continuous asteroid and comet monitoring, and rapid, controlled modification of the orbital trajectories of selected bodies. CAPS would provide an orbit modification system capable of diverting kilometer class objects, and modifying the orbits of smaller asteroids for impact defense and resource utilization.

This paper provides a summary of CAPS and discusses several key areas and technologies that are being investigated. Exploring the Concept of Healing Spaces. Evidence-based design EBD research has demonstrated the power of environmental design to support improved patient, family, and staff outcomes and to minimize or avoid harm in healthcare settings.

While healthcare has primarily focused on fixing the body, there is a growing recognition that our healthcare system could do more by promoting overall wellness, and this requires expanding the focus to healing. This article explores how we can extend what we know from EBD about health impacts of spatial design to the more elusive goal of healing. By breaking the concept of healing into antecedent components emotional, psychological, social, behavioral, and functional , this review of the literature presents the existing evidence to identify how healthcare spaces can foster healing.

The environmental variables found to directly affect or facilitate one or more dimension of healing were organized into six groups of variables-homelike environment, access to views and nature, light, noise control, barrier-free environment, and room layout. While there is limited scientific research confirming design solutions for creating healing spaces , the literature search revealed relationships that provide a basis for a draft definition.

Healing spaces evoke a sense of cohesion of the mind, body, and spirit. They support healing intention and foster healing relationships. Nanotechnology is the art and science of building materials and devices at the ultimate level of finesse: atom by atom. Our nation's space program has need for miniaturization of components, minimization of weight, and maximization of performance, and nanotechnology will help us get there.

MSFC has a dedicated group of technologists who are currently developing high-payoff nanotechnology concepts. This poster presentation will outline some of the concepts being developed including, nanophase structural materials, carbon nanotube reinforced metal and polymer matrix composites, nanotube temperature sensors, and aerogels. The poster will outline these concepts and discuss associated technical challenges in turning these concepts into real components and systems.

Systemizing the Pedagogic Concepts. Directory of Open Access Journals Sweden. Full Text Available The paper emphasizes the necessity of systemizing the pedagogic concepts to complement the pluralism principle dominating in pedagogy over the recent years. The author recommends the person oriented systematic synergetic methodology combining various research data into a holistic scientific approach. The paper regards education as the core pedagogic concept - including training, upbringing, self-education, their respective subcomponents, and generated personal resource.

The elements of personal resource combine the acquired knowledge, skills and values, developed subjective attitudes and individual health data. The key pedagogic terms describing the educational process are represented by a three-level system ; the first level involves the educational form concepts , the second — generated personal resource, the third — summarized notion system combining the previous levels and reflecting their binary relations.

The given construct systemizes the pedagogic conceptual apparatus and clarifies the theoretical notion of personal education. Space Van system update. This price includes return on preoperational investment. The Space Van is a fully reusable, assisted-single-stage-to orbit system. The most innovative new feature of the Space Van system is the assist-stage concept. The assist stage uses only airbreathing engines for vertical takeoff and vertical landing in the horizontal attitude and for launching the rocket-powered orbiter stage at mach 0.

The primary version of the orbiter is designed for cargo-only without a crew. However, a passenger version of the Space Van should be able to carry a crew of two plus six passengers to a space -station orbit. Since the Space Van is nearly single-stage, performance to polar orbit drops off significantly. The cargo version should be capable of carrying kg to a km polar orbit. In the passenger version, the Space Van should be able to carry two crew members - or one crew member plus a passenger.

RoMPS concept review automatic control of space robot. The Robot operated Material Processing in Space RoMPS experiment is being performed to explore the marriage of two emerging space commercialization technologies: materials processing in microgravity and robotics.

This concept review presents engineering drawings and limited technical descriptions of the RoMPS programs' electrical and software systems. Concept of adaptability in space modules. The space program is aiming towards the permanent use of space ; to build and establish an orbital space station, a Moon base and depart to Mars and beyond. We must look after the total independency from the Earth's natural resources and work in the design of a modular space base in which each module is capable of duplicating one natural process, and that all these modules in combination take us to conceive a space base capable of sustaining life.

Every area of human knowledge must be involved. This modular concept will let us see other space goals as extensions of the primary project. The basic technology has to be defined, then relatively minor adjustments will let us reach new objectives such as a first approach for a lunar base and for a Mars manned mission. This concept aims towards an open technology in which standards and recommendations will be created to assemble huge space bases and spaceships from specific modules that perform certain functions, that in combination will let us reach the status of permanent use and exploration of space.

Hybrid system concepts. Hybrid systems studied for fissile material production, were reconsidered for minor actinide and long-lived fission product destruction as alternative to the traditional final disposal of nuclear waste. Now there are attempts to extend the use of the concepts developed for minor actinide incineration to plutonium burning. The most promising hybrid system concept considers fuel and target both as liquids. From the results obtained, the possibility to adopt composite targets seems the most promising solution, but still there remains the problem of Pu production, not acceptable in a burning system.

This kind of targets can be mainly used for fissile material production, while for accelerator driven burners it is most convenient to use a liquid lead target. The most suitable solvent is heavy water for minor actinide annihilation in the blanket of a hybrid system. Due to the criticality conditions and the necessity of electric energy production, the blanket using plutonium dissolved in molten salts is the most convenient one. Advanced mission studies are the first step in determining the feasibility of a given space exploration concept.

A space scientist develops a science goal in the exploration of space. This may be a new observation method, a new instrument or a mission concept to explore a solar system body. In order to determine the feasibility of a deep space mission, a concept study is convened to determine the technology needs and estimated cost of performing that mission.

Heuristics are one method of defining viable mission and systems architectures that can be assessed for technology readiness and cost. Developing a viable architecture depends to a large extent upon extending the existing body of knowledge, and applying it in new and novel ways. These heuristics have evolved over time to include methods for estimating technical complexity, technology development, cost modeling and mission risk in the unique context of deep space missions.

This paper examines the processes involved in performing these advanced concepts studies, and analyzes the application of heuristics in the development of an advanced in-situ planetary mission. The Venus Surface Sample Return mission study provides a context for the examination of the heuristics applied in the development of the mission and systems architecture.

This study is illustrative of the effort involved in the initial assessment of an advance mission concept , and the knowledge and tools that are applied. Concept research on general passive system. This paper summarized the current passive techniques used in nuclear power plants. Through classification and analysis, the functional characteristics and inherent identification of passive systems were elucidated.

By improving and extending the concept of passive system , the general passive concept was proposed, and space and time relativity was discussed and assumption of general passive system were illustrated.

Benefits of space exploration

The function of idealized general passive system is equivalent with the current passive system , but the design of idealized general passive system is more flexible. Habitability Concept Models for Living in Space. As growing trends show, living in " space " has acquired new meanings, especially considering the utilization of the International Space Station ISS with regard to group interaction as well as individual needs in terms of time, space and crew accommodations.

Habitability Concept Models can improve the methods and techniques used to support the interior design and layout of space architectures and at the same time guarantee a human focused approach. This paper discusses and illustrates some of the results obtained for the interior design of a Habitation Module for the ISS. In this work, two different but complementary approaches are followed. Hall, and Francesca Pregnolato, This approach offers flexible and adaptive design solutions.

The second is "subject oriented" and based on a Virtual Reality environment. With this approach human perception and cognitive aspects related to a specific crew task are considered. Data obtained from these two approaches are used to verify requirements and advance the design of the Habitation Module for aspects related to man machine interfaces MMI , ergonomics, work and free-time. It is expected that the results achieved can be applied to future space related projects. Analysis of space station requirements for LDR. A study was conducted to determine how the Large Deployable Reflector LDR might benefit from the use of the space station for assembly, checkout, deployment, servicing, refurbishment, and technology development.

Requirements that must be met by the space station to supply benefits for a selected scenario are summarized. Quantitative and qualitative data are supplied.

Benefits of space exploration - Wikipedia

Space station requirements for LDR which may be utilized by other missions are identified. A technology development mission for LDR is outlined and requirements summarized. A preliminary experiment plan is included. Alternative power generation concepts for space. With the advent of the NASA Space Station, there has emerged a general realization that large quantities of power in space are necessary and, in fact, enabling.

Several factors led to the consideration of solar dynamic and nuclear power systems. These include better scaling to high power levels, higher efficiency conversion and storage subsystems, and lower system specific mass. The objective of this paper is to present the results of trade and optimization studies that high-light the potential of solar and nuclear dynamic systems relative to photovoltaic power systems.

There are papers on the technology needed for LDSMs. Few are looking at how groundbased pre-mission training and on-board in-transit training must be melded into one training concept that leverages this technology. Even more importantly, fewer are looking at how we can certify crews pre-mission. This certification must ensure, before the crew launches, that they can handle any problem using on-board assets without a large ground support team. Advances in solar array and electric thruster technologies now offer the promise of new, very capable space transportation systems that will allow us to cost effectively explore the solar system.

NASA has developed numerous solar electric propulsion spacecraft concepts with power levels ranging from tens to hundreds of kilowatts for robotic and piloted missions to asteroids and Mars. During the s several discoveries and advances in the development of carbon nano-tube CNT materials indicated that material strengths many times greater than common high-strength composite materials might be possible.

Progress in the development of this material led to renewed interest in the space elevator concept for construction of a tether structure from the surface of the Earth through a geostationary orbit GEO and thus creating a new approach to Earth-to-orbit transportation infrastructures. To investigate this possibility the author, in , managed for NASA a space elevator work:hop at the Marshall Space Flight Center to explore the potential feasibility of space elevators in the 21 century, and to identify the critical technologies and demonstration missions needed to make development of space elevators feasible.

This paper will review some of the latest ideas for space elevator development, the critical technologies required, and some of the ideas proposed for demonstrating the feasibility for full-scale development of an Earth to GEO space elevator. Critical technologies include CNT composite materials, wireless power transmission, orbital object avoidance, and large-scale tether deployment and control systems.

Numerous paths for technology demonstrations have been proposed utilizing ground experiments, air structures. In conclusion, this paper finds that the most critical technologies for an Earth to GEO space elevator include CNT composite materials development and object avoidance technologies; that lack of successful development of these technologies need not preclude continued development of. Full Text Available Integral Education, despite being the subject of public policy agenda for some decades, still carries disparities related to its concept.

In this sense, this article aims to problematize not only the concepts of integral education but also the categories time and space contained in the magazines Em Aberto. The work reveals convergent and divergent conceptual multiplicity, provoking a discussion about a critical conception of integral education. Keywords: Integral Education. Historical-Critical Pedagogy. Content Analysis.

Materials and design concepts for space -resilient structures. Space exploration and terraforming nearby planets have been fascinating concepts for the longest time. Nowadays, that technological advancements with regard to space exploration are thriving, it is only a matter of time before humans can start colonizing nearby moons and planets. This paper presents a state-of-the-art literature review on recent developments of " space -native" construction materials, and highlights evolutionary design concepts for " space -resilient" structures i.

This paper also details effects of harsh and unique space environments on various terrestrial and extraterrestrial construction materials, as well as on space infrastructure and structural systems. The feasibility of exploiting available space resources in terms of "in-situ resource utilization" and "harvesting of elements and compounds", as well as emergence of enabling technologies such as "cultured lab-grown " space construction materials are discussed. Towards the end of the present review, number of limitations and challenges facing Lunar and Martian exploration, and venues in-need for urgent research are identified and examined.

Topics include and overview, science objectives, study objectives, coronagraph types, metrics, ACCESS observatory, laboratory validations, and summary. Optimization of operating parameters of ground source heat pump system for space heating and cooling by Taguchi method and utility concept. In the present research, a methodology is proposed to optimize the operating parameters of a GSHP system which will operate on both heating and cooling modes. Condenser inlet temperature, condenser outlet temperature, dryness fraction at evaporator inlet and evaporator outlet temperature are considered as the influencing parameters of the heat pump.

Optimization of these parameters for only heating or only cooling mode operation is achieved by employing Taguchi method for three level variations of the above parameters using an L 9 3 4 orthogonal array. Higher the better concept has been used to get a higher COP. Based on this analysis, the maximum COP for only heating and only cooling operation are obtained as 4.

By making use of the utility concept both the higher values of COP obtained for heating and cooling modes are optimized to get a single optimum COP for heating and cooling modes. A single. Volume 2: Concept development and selection. The overall program background, the various system concepts considered, and the rationale for the selected design are described.

The concepts for each subsystem are also described and compared. The various concepts for utilizing thermionic conversion in space reactor power plants are described and evaluated. The problems and progress toward their solution of the in-core concept , particularly, are considered. Progress in thermionic conversion technology is then reviewed from both the hardware and research points of view. Anticipated progress in thermionic conversion and the possible consequences for the performance of electrical propulsion systems are summarized.

Sustainable spacecraft life support concepts may allow the development of more reliable technologies for long duration space missions. Currently, life support technologies at different levels of development are not well evaluated against each other, and evaluation methods do not account for long term reliability and sustainability of the hardware. This paper presents point-of-departure sustainability evaluation criteria for life support systems , that may allow more robust technology development, testing and comparison.

An example sustainable water recovery system concept is presented. The concept of temperature in space plasmas. Independently of the initial distribution function, once the system is thermalized, its particles are stabilized into a specific distribution function parametrized by a temperature. Classical particle systems in thermal equilibrium have their phase- space distribution stabilized into a Maxwell-Boltzmann function. In contrast, space plasmas are particle systems frequently described by stationary states out of thermal equilibrium, namely, their distribution is stabilized into a function that is typically described by kappa distributions.

The temperature is well-defined for systems at thermal equilibrium or stationary states described by kappa distributions. This is based on the equivalence of the two fundamental definitions of temperature, that is i the kinetic definition of Maxwell and ii the thermodynamic definition of Clausius This equivalence holds either for Maxwellians or kappa distributions, leading also to the equipartition theorem.

The temperature and kappa index together with density are globally independent parameters characterizing the kappa distribution. While there is no equation of state or any universal relation connecting these parameters, various local relations may exist along the streamlines of space plasmas. Observations revealed several types of such local relations among plasma thermal parameters. Habitat Concepts for Deep Space Exploration. Future missions under consideration requiring human habitation beyond the International Space Station ISS include deep space habitats in the lunar vicinity to support asteroid retrieval missions, human and robotic lunar missions, satellite servicing, and Mars vehicle servicing missions.

Habitat designs are also under consideration for missions beyond the Earth-Moon system , including transfers to near-Earth asteroids and Mars orbital destinations.

Account Options

A variety of habitat layouts have been considered, including those derived from the existing ISS designs and those that could be fabricated from the Space Launch System SLS propellant tanks. This paper presents a comparison showing several options for asteroid, lunar, and Mars mission habitats using ISS derived and SLS derived modules and identifies some of the advantages and disadvantages inherent in each.

Key findings indicate that the larger SLS diameter modules offer built-in compatibility with the launch vehicle, single launch capability without on-orbit assembly, improved radiation protection, lighter structures per unit volume, and sufficient volume to accommodate consumables for long duration missions without resupply. The information provided with the findings includes mass and volume comparison data that should be helpful to future exploration mission planning efforts. On the Concept of Hydrologic Space. Forests provide a number of important water-related ecosystem services including water purification and flood mitigation.

We illustrate that the forest role in precipitation recycling and the regulation of the hydrologic cycle must also be clearly recognized as an ecosystem service. Deforestation leads to more local runoff and reduced precipitation. However, the importance of afforestation in contributing to the flow of atmospheric moisture and thus promoting precipitation recycling is underappreciated.

System Error Occurred.

Since much of the evapotranspiration from forests falls again as precipitation, the terrestrial, forest-based production of atmospheric moisture has important consequences, both for local and downwind precipitation and water availability. We emphasize the importance of inter-basin connectivity: what happens in one basin cannot be separated from what happens in others. Country of Publication: US Dimensions cm : Help Centre.
