This book explains how it came to be that Venus and Earth, while very similar in chemical composition, zonation, size and heliocentric distance from the Sun, are very different in surface environmental conditions. It is argued here that these differences can be accounted for by planetoid capture processes and the subsequent evolution of the planet-satellite system. Venus captured a one-half moon-mass planetoid early in its history in the retrograde direction and underwent its “fatal attraction scenario” with its satellite (Adonis). Earth, on the other hand, captured a moon-mass planetoid (Luna) early in its history in prograde orbit and underwent a benign estrangement scenario with its captured satellite.

"Early robot probes sent by Russian and American scientists had given us some tantalizing but fragmentary glimpses of the surface and atmosphere, hinting at some of the most exotic conditions seen in the solar system. Magellan showed a planet full of beautiful landscapes, some eerily familiar and some completely unexpected - a world of active volcanoes, shining mountains, and even river valleys carved by torrents of flowing lava. Venus may once have had a wet, temperate, comfortable climate, much like Earth's. What happened to turn it into a hostile, burning, acid world? Our twin has important tales to tell us regarding several of Earth's most pressing environmental problems, including ozone destruction, global warming, and acid rain. In Venus Revealed, David Grinspoon makes a compelling case for comparative planetology as an important tool for gaining knowledge that is vital for our long-term survival on our own planet. He re-examines the uniqueness of our own Earth in light of the recent Magellan findings, while also raising the provocative questions: Did a runaway greenhouse effect transform Venus into the burning oven she is today? By treating Venus as a "controlled experiment," what can we learn from her that will help us survive on Earth? Grinspoon tackles these and other long-debated questions while explaining the incredible scientific advances made possible by the Magellan space probe."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

In this work Toby L. Murray RMT connects human anatomy and physiology to the Inverse Square Law and the Biological Tides Theory in support of the hypothesis that the Moons gravity generates a `Monthly Cranial Respiration Cycle` in cerebral spinal fluid which induces the secretion of neuro-endocrine hormones thus regulating bodily functions such as menstruation. This hypothesis further proposes that as the Moon steadily moves further away from Earth in a process known as the Lunar-recession the Monthly Cranial Respiration Cycle diminishes leading to conditions such as menopause, disease, and aging in-general. The author combines the ideas of the late astronomers Drs. Thomas Van Flandern and Robert Harrington with Newtonian Mechanics and General Relativity to demonstrate that Mercury is the moon to the planet Venus which separated from Venus in a process similar to the Moons recession from Earth. The resulting new models of the solar and planetary systems are that of atoms of eight `life essential` elements with properties belonging to the group of non-metals on the Periodic Table of Elements.

The planet Venus is the closest neighbour to the Earth and in several respects similar to our globe. It revolves around the Sun at an average distance of 0. 72 astronomical units, in an elliptical orbit of eccentricity 0. 007. The corresponding 3 numbers for the Earth are 1 and 0. 017. The mean density of Venus is 5. 2 g/cm , 3 that of the Earth 5. 5 g/cm . Venus’ acceleration of gravity at its equator is 8. 9 2 2 m/s , compared with 9. 8 m/s at the Earth. The escape velocity is 10. 4 km/s, while the corresponding ?gure of the Earth is 11. 2 km/s. Although the mass of Venus is somewhat smaller than that of the Earth – the ratio is M /M =0. 815 V E – the diameters of the two planets are almost the same. In other words, Venus is indeed a sister planet of the Earth. In earlier times, when almost nothing was known about the physical con- tions of Venus, the similarity appeared even stronger than today. Not only was Venus’ period of rotation thought to be close to that of the Earth, it was also p- sible (and indeed common) to imagine intelligent life on Venus.

This book offers an exercise in theoretical planetology, presenting five different scenarios to assess the evolution of habitable conditions on Mars to assess planetary terraforming potential and to give insight into the ongoing search for habitable exoplanets. Four of the scenarios involve Martian satellite capture models, in which gravitational capture via tidal deformation and energy dissipation processes are measured to predict a pathway of biological evolution, while the fifth scenario analyzes the possible model that led to the Mars that we have today (i.e. with no life forms). In ten chapters, readers will learn how a Mars-like terrestrial planet can be transformed into a habitable planet, and what conditions must be assessed when searching for exoplanets in a star-centered orbit to support life. The book is intended for planetologists, and general enthusiasts of planetary evolution and our solar system.
