Moon - Prospective Energy and Material Resources (Hardcover, 2012): Viorel Badescu Moon - Prospective Energy and Material Resources (Hardcover, 2012)
Viorel Badescu
R6,629 Discovery Miles 66 290 Ships in 10 - 15 working days

The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration. In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon's prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources. The book collects together recent proposals and innovative options and solutions. It is a useful source of condensed information for specialists involved in current and impending Moon-related activities and a good starting point for young researchers.

The papers in this volume aim to represent the most up-to-date research contributions on the observations, theoretical interpretations, and empirical and physical models of variations observed in solar and stellar irradiances, as well as on Sun-climate connections. Both theoretical studies and irradiance observations show that the energy output of the Sun and solar-type stars varies, changing on time scales related to the short-term surface manifestations of solar/stellar magnetic activity as well as long-term modulations driven by processes in the interiors of the stars. Papers presented in this book point out that at the Earth these variations influence the terrestrial climate, radiative environment and upper atmospheric chemistry.

The magnetosphere is the region in which the solar wind interacts with the Earth's magnetic field, the zone which screens the Earth from most of the harmful cosmic rays which daily bombard it. The Aurora Borealis, or Norhun lights, other such phenourena result from the interaction of particles in the solar wind and the magnetosphere. Planetary physicists, geophysicists, plasma astrophysicists, and scientists involved with astronautics all have a primary interest in the configuration and dynamics of the magnetosphere, and much research is devoted to convection (the circulation of solarwind plastma in the magnetiosphere) and substorms, which are linked to the aurorae and thought to stimulate convection. In this book, one of the leading scientists in the field presents a synthesis of current knowledge on convection and substorms and proposes that the Planetary physicists, geophysicists, plasma astrophysicists, and scientists involved with astronautics all have a primary interest in the configuration and dynamics of the magnetosphere, and much research is devoted to convection (the circulation of solarwind plastma in the magnetiosphere) and substorms, which are linked to the aurorae and thought to stimulate convection.

R4,262 Discovery Miles 42 620 Ships in 18 - 22 working days

The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) satellite was launched on 5 February 2002. Its objective is to study the energy release and particle acceleration in solar flares through observations of X-rays and gamma rays. Two novel technologies are combined to obtain both spectra and images over a broad energy range. For the spectroscopy, cooled hyperpure germanium detectors are used to cover the energy range from 3 keV to 17 MeV with unprecedented keV-class resolution. Since focusing optics are not possible for making images with such high energy photons, tungsten and molybdenum absorbing grids are used to modulate the X-rays and gamma-rays coming from the Sun as the spacecraft rotates. This allows the spatial Fourier components of the source to be determined so that images can be made in spectral ranges where astronomical images have never been produced before. These new instrumental techniques require equally innovative software to reconstruct X-ray and gamma-ray spectra and images from the observations.

Ample solar activity, abundant observations, and an open data policy have attracted many researchers. Astronomers face in the RHESSI mission an exciting new scientific potential. It has unusually broad possibilities for improving our understanding of the enigmatic solar flare phenomenon that is becoming increasingly important as society depends more and more on space-based technologies.
In this volume, the functioning of RHESSI is explained, the data analysis techniques including spectroscopy and image reconstruction are introduced, and the experiences of the first few months of operation are summarized. First scientific results are presented thatprovide the essential base for more extended studies using RHESSI data and complementary observations by instruments on other spacecraft and at ground-based solar observatories.

The accompanying CD-ROM contains X-ray and EUV movies showing the dynamics of several solar flares. It also contains color versions of the graphics in the printed papers and additional material.

Scientists and students will find here the latest discoveries in solar flare research, as well as inspiration for future work. The papers will serve as references for the many new discoveries to come from the continuing RHESSI observations.
