Book excerpt: This reports the results of a general study for NASA Lewis in relation to the use of small satellites for a Mars Relay Satellite (MRS) that supports communications between Mars and Earth: commands to, and telemetry from, Mars Landers and Rover. The scope of the study encompasses a survey of small satellites, those that are lower than 800 kg in mass, by NASA, DoD, and commercial companies. Additionally, surveys in advanced technologies in the area of composite materials, propulsion subsystems, battery subsystems, communications components and subsystems, and ground operations are also provided, A summary of NASA Mars Programs and their status as relevant to MRS is also included. Attempts to draw detailed cost conclusion is generally not possible due to its proprietary nature. In any event, cost is driven by market demands rather than new technologies. A preliminary comparison with the cost estimate of the S-Tel/OSC report did suggest the possibility of cost savings for the MRS by the use of production busses. On the other hand, cost savings in normalized terms from the use of automated ground systems were obtained with some degree of details.

This book was released on 2016-11-06 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space-based observations have transformed our understanding of Earth, its environment, the solar system and the universe at large. During past decades, driven by increasingly advanced science questions, space observatories have become more sophisticated and more complex, with costs often growing to billions of dollars. Although these kinds of ever-more-sophisticated missions will continue into the future, small satellites, ranging in mass between 500 kg to 0.1 kg, are gaining momentum as an additional means to address targeted science questions in a rapid, and possibly more affordable, manner. Within the category of small satellites, CubeSats have emerged as a space-platform defined in terms of (10 cm x 10 cm x 10 cm)- sized cubic units of approximately 1.3 kg each called "U's." Historically, CubeSats were developed as training projects to expose students to the challenges of real-world engineering practices and system design. Yet, their use has rapidly spread within academia, industry, and government agencies both nationally and internationally. In particular, CubeSats have caught the attention of parts of the U.S. space science community, which sees this platform, despite its inherent constraints, as a way to affordably access space and perform unique measurements of scientific value. The first science results from such CubeSats have only recently become available; however, questions remain regarding the scientific potential and technological promise of CubeSats in the future. Achieving Science with CubeSats reviews the current state of the scientific potential and technological promise of CubeSats. This report focuses on the platform's promise to obtain high- priority science data, as defined in recent decadal surveys in astronomy and astrophysics, Earth science and applications from space, planetary science, and solar and space physics (heliophysics); the science priorities identified in the 2014 NASA Science Plan; and the potential for CubeSats to advance biology and microgravity research. It provides a list of sample science goals for CubeSats, many of which address targeted science, often in coordination with other spacecraft, or use "sacrificial," or high-risk, orbits that lead to the demise of the satellite after critical data have been collected. Other goals relate to the use of CubeSats as constellations or swarms deploying tens to hundreds of CubeSats that function as one distributed array of measurements.
Download or read book The Role of Small Satellites in NASA and NOAA Earth Observation Programs written by National Research Council and published by National Academies Press. This book was released on 2000-05-12 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote observations of Earth from space serve an extraordinarily broad range of purposes, resulting in extraordinary demands on those at the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and elsewhere who must decide how to execute them. In research, Earth observations promise large volumes of data to a variety of disciplines with differing needs for measurement type, simultaneity, continuity, and long-term instrument stability. Operational needs, such as weather forecasting, add a distinct set of requirements for continual and highly reliable monitoring of global conditions. The Role of Small Satellites in NASA and NOAA Earth Observation Programs confronts these diverse requirements and assesses how they might be met by small satellites. In the past, the preferred architecture for most NASA and NOAA missions was a single large spacecraft platform containing a sophisticated suite of instruments. But the recognition in other areas of space research that cost-effectiveness, flexibility, and robustness may be enhanced by using small spacecraft has raised questions about this philosophy of Earth observation. For example, NASA has already abandoned its original plan for a follow-on series of major platforms in its Earth Observing System. This study finds that small spacecraft can play an important role in Earth observation programs, providing to this field some of the expected benefits that are normally associated with such programs, such as rapid development and lower individual mission cost. It also identifies some of the programmatic and technical challenges associated with a mission composed of small spacecraft, as well as reasons why more traditional, larger platforms might still be preferred. The reasonable conclusion is that a systems-level examination is required to determine the optimum architecture for a given scientific and/or operational objective. The implied new challenge is for NASA and NOAA to find intra- and interagency planning mechanisms that can achieve the most appropriate and cost-effective balance among their various requirements.

Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of the 2014 Reinventing Space conference present a number of questions in the context of a constantly innovating space industry, from addressing the future of global cooperation, investigating the impact of cuts in US government spending on the private space sector, and probing the overall future of the commercial launch sector. Space tourism and new technology promise the revival of interest in space development (the Apollo Era was the first period of intense space activity and growth). The need to create dramatically lower cost, responsive and reliable launch systems and spacecraft has never been more vital. Advances in technology are allowing smaller and cheaper satellites to be orbited - from cubesats to nanosatellites to femtosatellites. Thanks to more efficient new launch possibilities, low cost access to space is becoming ever more achievable. Commercial companies and countries are targeting the industry with new funding. Organised by the British Interplanetary Society, the presentations at this conference thoroughly address these challenges and opportunities.

This book was released on 2008 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Using a solar sail, the Solar Polar Imager mission would observe the Sun from a polar orbit to observe magnetic fields and convective flows in the polar regions as well as coronal mass ejections and the Sun's outer atmosphere in order to better understand the solar dynamo and solar activity. Titan Explorer mission includes an orbiter with remote sensing instruments and an airship platform to investigate the atmosphere, clouds, haze, and surface of Saturn's moon Titan. Neptune Orbiter with Probes mission would use aerocapture to explore Neptune's rings and magnetosphere, which serve as an analog for the primordial solar nebula and accretion disks around other stars, and its satellite Triton, which resembles small objects at the outer boundary of our solar system today. Neptune Orbiter, Probe, and Lander mission would use nuclear electric propulsion to investigate Neptune and orbit its satellite, Triton. Interstellar Probe would leave the heliosphere to explore interstellar space, learning about its composition and dynamics and its interaction with our solar system. Observing distant stars with ultra-high resolution, the Stellar Imager mission could reveal their magnetic activity and internal structure, helping us understand solar activity and magnetohydrodynamics throughout the Universe. By bringing our understanding of other galaxies nearly up to our understanding of our own, the Modern Universe Space Telescope could illuminate how the chemical elements are created and dispersed, how normal galaxies form and evolve, and how stars and planetary systems form. Generation-X mission could detect the first black holes formed when the Universe was only a few hundred million years old. Advanced Compton Telescope is a wide-field gamma-ray spectrometer designed to uncover how supernovae and other stellar explosions create the chemical elements through an all-sky survey of nuclear line emissions. Far-Infrared/Submillimeter Interferometer in Space would use a two-element array to study the formation of the earliest-born stars and galaxies in the Universe and to probe the structure of the disks of gas and dust collapsing today to form a new generation of stars and planets. Single Aperture Far Infrared Observatory would be a single-spacecraft large space telescope for observing the early chemical history of the Universe and the structure of young planetary systems, tracking the chemistry needed for life from interstellar clouds to young solar systems. A final chapter describes an analysis of directions for future technology development inspired by this portfolio of mission concepts."--Publisher description.

Download or read book Reducing Space Mission Cost written by James R. Wertz and published by Springer. This book was released on 1996-07-31 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing Space Mission Cost is the first complete treatment of the technology, process, and problems in the most critical areas of modern spaceflight. The demand to reduce cost is unrelenting. This pioneering book addresses all aspects of this problem, including: Technology and processes for reducing cost Cost reduction in mission engineering, spacecraft design, manufacture, launch, and operations Implementation methods and problems The price of reducing cost 10 detailed case studies of what works in practice in: Science missions Interplanetary probes Communications spacecraft Test and Applications missions Beginning on the inside front cover, this book provides real cost data on a variety of missions, systems, and subsystems. According to the authors: `Reducing mission cost is hard enough if you know what the real costs are, and virtually impossible if you don't.' This book challenges traditional methods, yet recognizes that all space programs are run to minimize cost within the rules under which they are built and flown. It provides practical recipes for reducing cost in both new and ongoing missions and discusses what works, what government can do to help, and what methods intended to reduce cost may be counterproductive and unintentionally increase cost. As shown on the inside rear cover, the case studies described in the book have reduced total mission cost by 80% to more than 90% with respect to projections by traditional cost methods. This book is a follow-on to the now standard text and reference, Space Mission Analysis and Design, also edited by Drs. Wertz and Larson. It is required reading for professionals, students, and managers in astronautics or space sciences and managers or scientists involved in space experiments. This book shows that reducing space mission cost, without reducing reliability, is as possible as it is important for the future of space exploration.
