This is the ultimate, easy-to-read guide for 'eclipse-chasers'. Eclipse chasers are now numbered in the tens of thousands. Every total solar eclipse sees dozens of cruise ships, each with about a thousand people on board, steaming along the track of the eclipse. Tens of thousands of observers travel to the eclipse track on land, to witness these rare astronomical events. There are some important eclipses coming up in the years ahead: in 2008 August across Siberia, and then through the Gobi Desert. In 2009, there is a six minute 38 second eclipse (very long) in China, south of Japan, and the Pacific Ocean. There will be two more big ones in the south Pacific in 2010 and 2012, then in 2017 there is a solar eclipse that will be visible right across the USA. The technology available to amateur astronomers is improving fast. Recent additions are low-cost white-light solar binoculars, and the new generation of affordable H-Alpha telescopes. These can of course be used to view prominences without an eclipse taking place, and the book includes something of this too.

В книге рассмотрена новая модель пространства Вселенной, которое не является пустым вместилищем для тел, а плотно заполнено мельчайшими частицами - максимонами. Все объекты в этой модели - пористые структуры внутри максимонной среды. Показано на конкретных примерах, что каждый объект окружен слоистой максимонной структурой, в которой возможно рождение новых частиц и тел из "пустоты". Гравитационные силы в этой модели объясняются градиентом давления максимонной среды, степень разреженности которой убывает по мере удаления от объекта обратно квадрату расстояния. На основании этой модели предлагаются принципиальные схемы антигравитационных двигателей различного типа. Дается объяснение левитации.

Satellites as they cross the night sky look like moving stars, which can be accurately tracked by an observer with binoculars as well as by giant radars and large cameras. These observations help to determine the satellite's orbit, which is sensitive to the drag of the upper atmosphere and to any irregularities in the gravity field of the Earth. Analysis of the orbit can be used to evaluate the density of the upper atmosphere and to define the shape of the Earth. Desmond King-Hele was the pioneer of this technique of orbit analysis, and this book tells us how the research began, before the launch of Sputnik in 1957. For thirty years King-Hele and his colleagues at the Royal Aircraft Establishment, Farnborough, developed and applied the technique to reveal much about the Earth and air at a very modest cost. In the 1960s the upper-atmosphere density was thoroughly mapped out for 100 to 2000 km, revealing immense variation of density with solar activity and between day and night. In the 1970s and 1980s a picture of the upper-atmosphere winds emerged, and the profile of the pear-shaped Earth was accurately charted. The number of satellites now orbiting the earth is over 5000. This book is the story of how this inexpensive research of their orbits developed to yield a rich harvest of knowledge about the Earth and its atmosphere, in a scientific narrative that is enlivened with many personal experiences.

Martian Outpost provides a detailed insight into the various technologies, mission architectures, medical requirements, and training needed to send humans to Mars. It focuses on mission objectives and benefits, and the risks and complexities that are compounded when linked to an overall planet exploration program involving several expeditions and setting up a permanent presence on the surface. The first section provides the background to sending a human mission to Mars. Analogies are made with early polar exploration and the expeditions of Shackleton, Amundsen, and Mawson. The interplanetary plans of the European Space Agency, NASA, and Russia are examined, including the possibility of one or more nations joining forces to send humans to Mars. Current mission architectures, such as NASA’s Constellation, ESA’s Aurora, and Ross Tierney’s DIRECT, are described and evaluated

Вот уже несколько столетий, используя все более и более мощные телескопы, астрономы пытливо вглядываются в крохотные, неясные изображения планет... За это время их движение было изучено почти досконально, но о самой природе этих небесных тел и о том, что происходит на их поверхности, ученые еще совсем недавно знали до обидного мало. За последние десятилетия XX века межпланетные космические станции побывали около всех планет, кроме Плутона, и заново открыли Солнечную систему. И мы тоже по-новому увидим планеты — от Меркурия до Плутона, — совершив прекрасное путешествие прямо на страницах этой книжки...

Deep Space Craft opens the door to interplanetary flight. It looks at this world from the vantage point of real operations on a specific mission, and follows a natural trail from the day-to-day working of this particular spacecraft, through the functioning of all spacecraft to the collaboration of the various disciplines to produce the results for which a spacecraft is designed. These results are of course mostly of a scientific nature, although a small number of interplanetary missions are also flown primarily to test and prove new engineering techniques. The author shows how, in order to make sense of all the scientific data coming back to Earth, the need for experiments and instrumentation arises, and follows the design and construction of the instruments through to their placement and testing on a spacecraft prior to launch. Examples are given of the interaction between an instrument’s science team and the mission’s flight team to plan and specify observations, gather and analyze data in flight, and finally present the results and discoveries to the scientific community.

The world’s most populous nation views space as an asset, not only from a technological and commercial perspective, but also from a political and militaristic one. The repercussions of this ideology already extend far beyond Washington. China vs. United States offers a glimpse of future Chinese aspirations in space and the politico-militaristic implications of a looming space race, and explains why an interplanetary spaceship called the Tsien Hsue Shen might one day travel to the outer planets. Until China successfully launched taikonauts into orbit, China’s space program had attracted little international attention. The book opens with an analysis of the short fifteen-year history of the China National Space Administration and its long list of accomplishments. Chapter 2 assesses Sino-U.S. technological and commercial interests in space and their implications in fuelling a potential space race. The national security objectives of the U.S. and China are examined, showing how their intentions are increasingly leading to the military integration of space technologies. Chapter 3 describes China’s anxieties about U.S. space power, its obsession with national prestige, and how manned spaceflight is viewed as a crucial element to sustain the legitimacy of the Communist Party. China is currently focusing on similar goals to those of NASA’s Constellation Program - lunar and Mars exploration. The following chapter examines the ambitious plans of both nations, and evaluates whether China’s bold goal of landing taikonauts on the Moon by 2020 is matched by the necessary capability.
